Résumé :

In modern times, one of the dangerous processes of biosphere pollution is pollution by heavy metals, they accumulate excessively in the atmosphere and pedosphere. Pollution by scale and degree of impact on biological objects, including humans, heavy metals occupy a special place among pollutants. Among heavy metals, especially dangerous pollutants are lead, mercury, cadmium. The source of pollution by heavy metals is mainly motor transport, ferrous and non-ferrous metallurgy enterprises, and waste. Waste from motor transport through the atmosphere gets into the soil and plants and poses a real threat to the environment.

Résumé :

The study evaluated the effect of industrial waste on soil pollution in Asaba, Delta State. The procedure adopted the ex post facto research model comprising a comprehensive range of simultaneous measures of industrial waste collection and soil quality in the selected industrial areas in Asaba. Industries in Asaba were selected based on the nature and type of industrial waste generated at random. Six existing industrial locations in Asaba were selected. The collected soil samples were used to investigate the soil pH, Zinc, Lead, Chromium, Silver and Copper concentration levels of the soils. Multiple regression was used to ascertain the effect of industrial waste on the soil in Asaba. 188071 Kg of industrial waste containing flammable, corrosive and toxic substances were generated at industrial landfills in Asaba. The industrial waste generated exceeds WHO standards. This is an implication that the industrial waste generated in Asaba is hazardous. The study revealed that most soils in industrial dumpsites are acidic and this is a reflection of the industrial waste's corrosive ability. Soils in the industrial dump sites are very high in Zinc, lead and chromium contents. Asaba Expressway 2 industrial dump sites have the highest amount of zinc and lead content, while Summit Junction industrial dump site has the highest content of silver. At a P<0.05 significance level, the calculated F value is 3.11 while the critical table value is 41.95. Thus, the toxicity in the soils in Asaba is significantly dependent on the chemical (Zinc, lead and Chromium) properties of industrial waste generation. Furthermore, as Zinc, lead and Chromium properties in industrial waste increase, the toxicity of the soil increases as well. Thus polluting the soils in Asaba industrial areas. The results obtained from this study portrayed that the Zero waste approach would be the recommended choice for sustainable waste management.

Résumé :

There is a growing public concern over the potential accumulation of heavy metals in soil, owing to rapid industrial development. In an effort to describe the status of the pollutions of soil by industrial activities, relevant data sets reported by many studies were surveyed and reviewed. The results of our analysis indicate that soils were polluted most significantly by metals such as lead, zinc, copper, and cadmium. If the dominant species are evaluated by the highest mean concentration observed for different industry types, the results were grouped into Pb, Zn, Ni, Cu, Fe, and As in smelting and metal production industries, Mn and Cd in the textile industry, and Cr in the leather industry. In most cases, metal levels in the studied areas were found to exceed the common regulation guideline levels enforced by many countries. The geoaccumulation index (Igeo), calculated to estimate the enrichment of metal concentrations in soil, showed that the level of metal pollution in most surveyed areas is significant, especially for Pb and Cd. It is thus important to keep systematic and continuous monitoring of heavy metals and their derivatives to manage and suppress such pollution.

Résumé :

The development of all spheres of human activity is associated with an increase in anthropogenic pressure on environment. Metropolitan areas and large cities are experiencing the greatest pressure. Both the development of new areas adjacent to built-up areas, as well as operating existing industrial and residential complexes suffer the influences. The article presents the results of a soil study conducted in the city of Novokuibyshevsk to determine the prospects for future growth of the city. Soil samples were taken throughout the city. When choosing the place of sampling, the locations of highways, industrial zones and residential buildings were taken into account. Soil testing was carried out to obtain data on the concentrations of heavy metals (lead, zinc, copper, cadmium, nickel, manganese, etc.), as well as sulfates and nitrates. The results were analyzed and contrasted with the standards and results of previous years.Based on the study of the current state of the soil, the authors assessed the degree of pollution of urban soils in an industrial city. In their study they proposed and developed measures to improve the condition of the soil, namely, analyzed the efficiency of using phytoremediation to reduce soil contamination in residential areas of the city.

Résumé :

Soil pollution by some heavy metals including: Cr, Mn, Fe, Ni, Cu, Zn, As, Mo, Cd and Pb from northern industrial area of Erbil City was assessed. The contamination indices including: geoaccumulation (Igeo), contamination factor (CF), enrichment factor (EF), degree of contamination (Cdeg), pollution load index (PLI) and element contamination index (ECI) were applied to assess soil pollution in Erbil North Industrial area at three sites (for both surface and sub-surface soils). Maximum Fe value 34243.6 ppm was recorded in sub-surface soil (site 2). Maximum values 265.4, 248.8, 98.23 and 397.45 ppm were recorded for Cr, Ni, Cu and Zn at sub-surface soil (site 3). Whereas, maximum values of 22.52, 5.36, 23.9, 6.12 and 65.67 ppm were recorded for As, Mo, Ag, Cd and Pb at surface soil (site 3). Results of analysed heavy metals for soil Cr, Mn, Fe, Ni, Cu, Zn, As, Mo, Ag, Cd and Pb have shown that the studied sites were severely contaminated with Cd, so the maximum detected Cd concentration was 6.12 ppm in surface soil (300 meters away from the industrial area). The soil pollution in the studied area was classified as moderate to strong surface and sub-surface soil contamination. Behavioral toxicity experiment showed slight growth effect on Lepidium sativum L.

Résumé :

A case study was conducted on the potential pollution in the soils surrounding three industrial facilities in Wasit City, Iraq. This includes the Zubaidiya Thermal Power Plant, the Textile Factory in Kut, and the Brick Factories in the Hai region, examining the impact of emissions resulting from incomplete fuel combustion and their liquid waste discharged into the river from these sources on the surrounding areas in terms of heavy metal pollution in the soil, such as titanium (Ti), iron (Fe), gallium (Ga), arsenic (As), bromine (Br), rubidium (Rb), strontium (Sr), yttrium (Y), zirconium (Zr), molybdenum (Mo), and barium (Ba). Soil samples were collected from distances ranging between 0-500 meters and depths of 0-30 cm and 30-60 cm near the pollution source to assess pollution levels based on global soil pollution standards. Comparison samples were also obtained 4 kilometers away from the pollution source at both depths, with three replicates for each site in October and March of 2023. In general, this indicates that industrial sites have an impact on pollution of the environment because the study found that the total concentration of heavy metals in soils affected by residues from these sites was higher than in control soils. When comparing the concentrations of heavy elements in the soil for October samples with the world average according to Kabata 2011, we found that the elements Iron, Gallium, and Rubidium were close to the world average, as well as the element Bromine, except for the first depth in the soil contaminated with the brick factory, where it was higher than the average. As for the elements Titanium, Arsenic, Strontium, Yttrium, and Molybdenum, their concentrations exceeded the world average, whether in the comparison soil or the contaminated soil. As for the elements Zirconium and Barium, they were lower than the world average, despite the fact that the concentrations in the contaminated soil were higher than the control samples, but their concentrations were lower than the average, according to Kabata 2011. As for the March samples, they followed the same trend as the October samples, indicating the extent of the contribution of pollution sources to the increase in concentrations of heavy elements in the soil in particular and the environment in general.

Résumé :

This study assessed the risks of soil pollution by heavy metals in Chilmari Upazila, northern Bangladesh, using the static environmental resilience (Pi) model of soil. Geostatistical modeling and self-organizing maps (SOM) identified pollution areas and spatial patterns, while a positive matrix factorization (PMF) model revealed pollution sources. The results showed that the average concentrations of Cr, Pb and As were well above background levels. Agricultural and industrial soils were mainly contaminated with Cr, Pb and As according to the Nemerow Pollution Index (NPI), Ecological Risk (ER) and Pi Index. Over 70% of the sites were contaminated with Pb and Cr, while co-contamination was particularly high. A one-way ANOVA showed significant correlations between Pb, Cu and Zn levels and human activities. The PMF analysis revealed that industrial effluents, agrochemicals and lithogenic sources were the main contributors to soil contamination with 16%, 41% and 43%, respectively. The SOM analysis revealed three distinct spatial patterns (Pb-Zn, Cr-Cu-Ni and Co-Mn-As), which are consistent with the PMF results. These results emphasize the need for stringent measures to reduce industrial emissions and remediate soil contamination in order to improve soil quality and food security.

Résumé :

We have carried out a retro-assessment of the data on metal pollution of soils in the city of Chisinau dated by the peak of industrial activity in the late 80s of the twentieth century. The proximity of geochemical spectra in soils of industrial areas and in children's institutions was observed. Statistical analysis of the main components indicated a high specialization of metal pollution in the industrial areas. Soil pollution in areas of children's institutions had a clear residential-transport character. The elimination of a multisectoral industrial production, the redevelopment of industrial areas and an increase in traffic intensity in the city over the past 30 years should have led to a significant change in the spatial structure and spectrum of pollution in the city of Chisinau.

Résumé :

With rapid industrialization in Gazipur areas of Bangladesh, untreated industrial effluents have been polluting rice soils which could exert potential ecological risk. Therefore, four different types of industries including chemical (SL), textile and paints (MIX), dyeing (CK), and sweater and dyeing (RD) were selected to monitor the intensity of heavy metal pollution in rice soils and ecological risk assessment. The di-acid digestion method was used for the determination of Pd, Cd, and Ni, and the DTPA extraction method was used for Fe, Zn, and Cu. ArcGIS was used to visualize the spatial patterns of heavy metal pollution, and different pollution indices were calculated to assess the ecological risk. The highest concentration (mg kg−1) of Cd (0.72), Pb (104.20), and Ni (5.02) was found in soils of the MIX industrial area. The highest concentration (mg kg−1) of Fe (147.65) and Zn (11.27) was found in the SL industry, while the highest Cu (7.67) was found in the CK industry. It was evident from the spatial distribution that the soils of paddy fields adjacent to the different industries are more contaminated than background soil. Although the potential ecological risk of heavy metal was low, different pollution indices indicated low to high pollution. Thus, the adjacent rice field soil of different industries is being contaminated by different heavy metals which may raise ecological risk.

Résumé :

The work aimed to evaluate the state of agricultural soil contamination what is important for the gaining of information needed for growing of hygienic safe raw materials and foodstuffs. Metallic pollution of soil in Zemplínska polluted area has begins by accumulation of heavy metals in soil, mainly resulting from location in vicinity of chemical and industrial factories, as well as from many others sources. The pH value development indicates gradual trend of soils acidification, except of alkalic ones reaching up to 20% from total arable soils in Slovakia. Acidification is process, where acidity of abiotic compounds has been increased. Soil reaction is a significant agrochemical property markedly affecting growing and developing of plants, and has directly effect on soil fertility, influencing the ecological conditions for plants and soil microorganisms. The site had been localised with GPS and 5 sampling places had been fixed. From these sites the soil samples were taken from 1 depth, A horizon (0–0,2 m) and then processed and managed according to particular ISO norms. The soil reaction and the heavy metals contents in solution of aqua regia and HNO3 in soil samples were assessed. Afterwards the gained results had been compared with limit values from legislative documents.

Résumé :

As a primary sink of pollutants, urban soil heavy metal pollution and its influence on urban residents and ecosystems has been becoming one of the most important environmental problems. In the present study, four indices, the Geoaccumulation index (Igeo), improved Nemerow index (IMN), degree of contamination (mCd), and contamination security index (CSI), as well as potential ecological risk (RI), were used to evaluate individual or integrated heavy metal pollution and its ecological risk for soil samples collected from city parks, the vicinity of a landfill, and an industrial area within the city of Guangzhou. The results indicated that the improved Nemerow index (IMN) calculated from the Geoaccumulation index was suitable for heavy metal pollution assessment of soils within landfills and industrial areas. As for soils collected from city parks, degree of contamination (mCd) was more suitable than IMN. Heavy metals Cd, Hg, Zn, and As were the main pollution elements in urban soils of Guangzhou. Potential ecological risks were mainly caused by Cd and Hg in urban soil of Guangzhou. Soil samples collected from city parks and the vicinity of the industrial area were moderately to highly and even extremely seriously polluted by heavy metals. Differing from the traditional cognition of the public, the ecological impact of heavy metal in soil in the vicinity of the landfill was similar to or even better than that within city parks.

Résumé :

The extensive pattern of economic growth has an inestimable negative impact on the ecological environment, which causes the soil pollution problem to become increasingly prominent. In order to improve the effectiveness and rationality of prevention and control of heavy metal pollution in regional soil, it is necessary to understand the current situation of pollution, identify pollution sources and clarify future pollution risks. In this paper, an industrially developed city in eastern China was taken as the study region. The positive matrix factorization model (PMF) model and Unmix model was applied to identify and apportion the pollution sources of soil potential toxic elements after evaluating the ecological risk of soil potential toxic elements. The PMF model identified six factors, including single source and composite source. The Unmix model also identified six sources, including sources of nature, industrial discharge and traffic emissions. The comparison between the two models showed that Hg and Ni pollution, as well as Cr enrichment in the study region, were related to the industrial discharge from enterprises and factories. Cd pollution was related to traffic emission sources. Cu and Zn pollution were related to the multiple sources mixed with soil parent material, traffic emissions and industrial discharge from electronic enterprises. Pb pollution was related to natural sources (e.g., soil pH) but also to industrial sources (e.g., industrial wastes discharge). Enrichment was related to soil parent material and agricultural inputs. Our study also implies that soil heavy metal pollution or enrichment in the study region was mainly from anthropogenic sources and supplemented by natural sources.

Résumé :

Soil pollution is one of the types of environmental pollution. Soils are as cathartic in nature. In addition to being suppliers of food, it has also refined property. This property can be obtained due to their physical properties, chemical properties and biological properties. One of the major concerns of today's agriculture is soil contaminated with pollutants harmful to human. Soil pollution is as a major environmental problem in the known world. Various sources of pollution such as agricultural pollution, oil pollution, heavy metals, industrial wastes and so reduce the quality of the soil, spread in groundwater levels and the incidence of other environmental problems. However, the lack of proper management of organic waste can lead to the increase of concentration of salts, heavy metals, pathogenic microorganisms, soil pollution, water pollution, agricultural products, fish etc.

Résumé :

Pollution in water bodies and soil is a major and ever-increasing environmental issue nowadays, and most conventional remediation approaches do not provide appropriate solutions. The contamination of soil is a major concern for the environment and needs to be remediated. These pollutants include complex organic compounds, heavy metals released from industries and plants and natural products such as oils from accidental release. Further the nature of pollution will be governed by the source and type of the contaminant, and other inorganic compounds are released into the environment from a number of sources like mining, smelting, electroplating, and farming. Plants can clean up many types of contaminants like metals, pesticides, oils, and explosives. Phytoremediation is emerging as a bio-based and low-cost alternative in the cleanup of heavy metal-contaminated soils.

Abstract. The heavy metal pollution of urban soil of industrial area and its impact on human healths becoming one of the environmental problems in Ulaanbaatar city of Mongolia. The purpose of this study was to determine spatial distribution and health risk of heavy metal pollution in soils surrounding area of leather processing factory and wastewater treatment plants (WWTP) of Ulaanbaatar city. Mapping the spatial distribution of contaminants in soils is the basis of pollution evaluation and risk control. Interpolation methods are extensively applied in the mapping processes to estimate the heavy metal (As, Zn, Pb, Cd, Cr, Cu) concentrations of topsoils. The average concentrations of Cr, Ni, Pb, Zn, Cu and As were 1986.9, 110.5, 111.0, 110.5, 53.5, 16.4 mg/kg, respectively. According to result as the soil pollution index with spatial distribution, a high pollution level for Cr while Zn, Cu and Pb have medium pollution levels. The soil pollution index (PI) values of heavy metals of study areas are, following descending orders Cr > Zn > Cu > Pb > As > Ni. The potential ecological risk of Cr, Cu, Pb, As indicated high ecological risk in the study area. The Hazard index values for almost all the metals were higher than 1, it is indicating a carcinogenic risk for children and adults. The risk index values of two metals (Cr, As) were contribute to a higher risk of development of cancer in humans. Heavy metal contamination can occur when soil particles are swept away from the initial pollution areas by the wind. Therefore, it is necessary to take measures to reduce soil pollution and encourage rehabilitation.

Résumé :

Soil pollution is a major challenge for ensuring a healthy environment and for human health. One of the critical points in soil pollution policy is the education and public awareness of the problem caused by soil pollution. Education influences decision-making on soil and water care. It is crucial to spread knowledge to undergraduate and graduate students about the determinantal effects of soil pollution on ecosystems and humans, considering today’s students are tomorrow’s guardians of soil and human health. A course on soil pollution aims to provide students with a foundation of the knowledge and skills required to work in this field. Knowledge of soil and contaminant properties, soil-pollutant interaction processes, transport of pollutants by soil and water, human health and ecological risk assessment, and measures for preventing soil pollution are fundamental for the sustainable management of soil and food safety. Students should be aware of the need to avoid the three types of soil pollution (chemical, radioactive, and biological) in industrial, agricultural, forest, and urban soils. This article provides a broad view of the knowledge taught in subjects related to soil pollution and introduces learning activities for undergraduate students.

Résumé :

This study evaluated the contamination of heavy metals (HMs) in the soil of 153 urban parks in Busan using soil pollution indices such as the single pollution index (PI), geoaccumulation index (Igeo), Nemerow pollution index (PIne), and potential ecological risk index (RI). The average concentration of each HM was 0–269.7% of the natural background concentration and 0–34.9% of the soil pollution warning standard. The artificial pollution level of cadmium (Cd) was higher than that of other HMs. The high degree of pollution of Cd may be related to emissions from industrial facilities and transport vehicles. Although the concentration of HMs are lower than the soil pollution warning standard, there is a possibility that HMs will accumulate due to point sources, such as various industrial activities, and non-point sources, such as vehicle pollution and import of soil from unknown sources. The PI and RI were used to determine the soil pollution levels of the urban parks. This study provides a policy basis for the management and hazard prevention of park soil pollution.

Résumé :

Existing methodological approaches to assessing the risk to public health from the effects of heavy metal pollution are highlighted. This article considers the influence of emissions from motor transport and industrial enterprises on the level of soil contamination by movable forms of heavy metals in different functional zones of the Odessa city. The degree of technogenic and chemical pollution of urban soils is determined by ecological indicators: concentration coefficient (Kc), hazard coefficient (Kn) and total pollution indicator (Zc). It is established that the indicators of the content of heavy metals in the humus horizons of the soils of Odessa city have a high variability and depend on the degree of industrial and transport impact. It was found that only the soils of the Botanical Garden have an optimal content of heavy metals. It is established that the soils are the most polluted by emissions from road transport in terms of lead (18 TVL), zinc (23 TVL) and cadmium (15 TVL). Accumulation of heavy metals was found in all studied soils of the city. The ecological condition of soils varies from optimal (park zone) to unsatisfactory condition (zone of joint influence of motor transport and industrial enterprises). In terms of total pollution, soils within the impact of road transport and industrial enterprises have a very high (extremely dangerous) level of pollution. The highest values of the total indicator of soil pollution were determined within the impact of road transport (Zc = 758.72) and the combined impact of industrial enterprises and road transport (Zc = 921.6). For the first time, a method was used to assess the risk to the health of the population of the Odessa city from the effects of soil contamination with heavy metals according to the probit regression model. It was determined that the study area of the city mainly has a high and dangerous risk to public health. The conducted researches allowed us to reveal the level of toxicity of the city soils and the level of danger to the health of the population, which will contribute to the implementation of appropriate measures to reduce pollution of the urban environment. The methodology for assessing the health risk from urban soil pollution by heavy metals is a promising approach to quality control of the system «environment – human health» and requires further research.

Résumé :

Introduction. The article presents the results of the study of the quality of soil cover in the cities located in the mountainous areas of the Trans-Urals in the Republic of Bashkortostan. The object of the study was the soil of lands for various purposes in cities of Uchaly, Sibay, and Baymak. In the study of soils of industrial zones, there were taken samples adjacent to the dumps and tailing dumps of mining production at a distance of up to 500 m. In the recreational zone there were included the territories of parks, in the residential zone - all micro-districts where the population of the city resides. There were investigated territories of collective gardens located near sources of pollution. Material and methods. The gross content of heavy metals and their mobile forms extracted from the soil of ammonium acetate buffer at pH 4.8 were determined by atomic absorption. Generally accepted ecological values of maximum permissible concentrations (MPC) and regional geochemical background (RGF) were used to estimate the degree of soil pollution. To assess the degree of soil pollution, the total ZC index was calculated using the formula proposed by Yu. E. Saet. Results. As a result of the study, in all studied samples of the soil excess of MPC on gross forms on the content of Cu, Zn, in some cases, Mn, Cd, Co was revealed. Calculations of the General norm of Zc showed urban soil lands of all types of purpose by gross content to belong to the category of permissible pollution. The level of soil contamination with heavy metals in all the studied cities is higher in soils for industrial purposes. Increased level of mobile forms of Cu, Zn, Mn, Cd was revealed in all studied soil samples. The soils of the residential zone of Baymak according to the content of mobile forms belong to the moderately dangerous category of pollution, the rest of the studied soils had an acceptable category of pollution. In the cities of Sibay and Uchaly, the territories adjacent to the quarry dumps belong to a particularly dangerous category of pollution. Conclusion. The level of soil contamination with heavy metals in urban areas of the Mountainous region of the Republic of Bashkortostan is determined by the type of destination of urban land. The most polluted are the soils of industrial zones located in close proximity to mining enterprises. The ecological danger of pollution is that in this zone there is a part of residential neighborhoods with knots, as well as garden cooperatives, where potatoes, vegetables and fruit and berry crops are grown.

Résumé :

At the end of the 20th century, a geoinformation database on soil degradation in Russia, relied on the soil map of Russia at a scale of 1 : 5 million, was developed under the leadership of V.S. Stolbovoy. As part of the development of this problem and in the course of obtaining new information on soil degradation, an attempt was made to refine and supplement this database, that relies on the soil map of the Russian Federation 1 : 2.5 million scale. Soil degradation resulted from the impact of various types of pollution was taken into account, including industrial emissions, leakage of oil products, excessive application of pesticides, the impact of vehicles and radiation pollution. Each soil polygon of the soil map exposed to the pollution was characterized by the degree and area of pollution in accordance with the developed scales. The results of the analysis were used to construct cartograms illustrating the spatial distribution of chemical and radiation degradation of the country soils. According to the data obtained, in the zone of pollution derived from industrial enterprises and oil pollution, 20% of the soil-geographic polygons of the map are characterized by a strong degree of pollution, and 30% and 50% – by weak and medium, respectively. Agricultural pollution due to excessive use of plant protection products in Russia does not exceed 10% of the area of polygons and is characterized by a low degree. About 10% of the soil polygons of the basic soil map are heavily contaminated with radioactive contamination, while 40% and 50% of the polygons are moderately and weakly contaminated, respectively. Pollution from vehicles is weak and generally has low level. At the same time, megacities and highways with heavy traffic are distinguished by relatively high level of pollution.

Résumé :

Introduction: Diesel oil is the most used petroleum product in Iran and other countries. The majority of diesel oil is stored in underground reservoirs and Fuel stations. This product can heavily pollute the adjacent soil. Diesel oil pollution has some ecological effects on soil that disturb the composition and diversity of the microbial community. The present research aimed to investigate the effects of diesel oil pollution on two different types of soil. Materials and Methods: To examine the effects of diesel oil on microbial communities, two different types of soil (industrial and forest types) were collected from Kerman province, Iran. Six microcosms were designed based on three microcosms existing in each type of soil, including unpolluted microcosm, polluted microcosm, and polluted microcosm with nutrients (Nitrogen and Phosphor). Some factors were assayed in each microcosm during 120 days of the experiment. These factors included total heterotrophic bacteria, total diesel oil-degrading bacteria, dehydrogenase enzyme, and diesel oil biodegradation. Results: The quantity of diesel oil-degrading bacteria was significantly lower than heterotrophic bacteria in all soil microcosms. The quantity of diesel oil-degrading bacteria had a decrement pattern until day 60 of the experiment, but after that, these bacteria had an increment pattern. The best dehydrogenase activity between different microcosms was related to polluting microcosms with diesel oil except for farmland soil. The highest biodegradation of diesel oil in all studied soil types belonged to the industrial microcosm (95%). Statistical analysis of the results indicated a significant correlation between the most probable number quantity of heterotrophic bacteria and other assayed factors. Forest soil was significantly different from other soil types. Conclusion: Given the obtained results of the current research, that forest soil is more sensitive to diesel oil pollution, compared to industrial soil. It is, therefore, possible to propose appropriate strategies for the bioremediation of different studied soil types.

Résumé :

The distribution and accumulation of heavy metals in the planting base soils in Shenyang, northeast of China, were investigated. Sixty soil samples were collected and characterized for heavy metals contents (AsCdCrPbHgNiCu and Zn). Concentration data were processed using correlation analysis and soils pollution assessment was carried out using geoaccumulation and PI. The results revealed that eight heavy metals contents of planting base all reached pollution level, which Pb and Hg pollution relatively serious, reached 2.41 and 2.1 respectively. The order of heavy metal pollution levels are: Pb> Hg> Zn = Cu> As> Ni> Cd> Cr. A significant correlation exists in Pb-Cd, Pb-Cu, Cd-As, Cu-Ni, while an extremely significant correlation exists between Zn-Cu. In addition to the parent material soil, the sources of soil heavy metals are mainly by the industrial, agricultural, transportation or other human activities and the effect of atmospheric transport and deposition.

Relevance. Potentially toxic elements serve as the most important indicators of environmental pollution, creating a potential risk for the ecology and health of the ecosystem, as well as humans in industrial regions. Soil is the main geochemical sink for various pollutants and provides a medium for the transport of many pollutants to the atmosphere, the hydropheric and biomass. Therefore, it is necessary to conduct a comprehensive study to assess geoecological risks from potentially toxic elements in soils. Aim. Assessment of the potential geoecological risk of soil contamination on the territory of the industrial site of the Udachny Mining and Processing Division using various pollution assessment indices. Objects. Dominant soil types in the northern taiga landscapes of the Daldyn kimberlite field. Methods. Atomic absorption, statistical methods. Results and conclusions. The author has carried out the assessment of potential sources of soil pollution and geoecological risks using such pollution indicators as the geoaccumulation index, Improved Nemerov index, pollution index, pollution load index, potential ecological risk. The soils of the study area are predominantly contaminated with Ni, Co, Cr and Mn. 19.51% of objects in the study area had a high potential environmental risk for Mn and Ni, and only 4.87% had a low potential environmental risk. Analysis of the spatial distribution of various pollution indices showed similar pictures. Local points with high values of pollution indices were identified. Hot spots were noted in the areas affected by the Udachny and Zarnitsa pipes dumps and tailings dump no. 2.

Résumé :

This study investigated the characteristics and sources of heavy metal(loid) pollution in the soil of a key industrial park in Kunming, China. In total, 60 soil samples (40 from agricultural land and 20 from construction land) were collected from and around the park. The soil pH and contents of Arsenic (As), lead (Pb), copper (Cu), zinc (Zn), cadmium (Cd), mercury (Hg), nickel (Ni), and chromium (Cr) were measured. The contents of the eight heavy metal(loid)s were analyzed using the background values of heavy metal(loid)s in the Kunming soil. The pollution load, geoaccumulation, and Nemero Comprehensive Pollution Indices were used for environmental risk evaluation. Cluster and principal component analyses were used to resolve heavy metal(loid) sources. Cd was enriched in construction and agricultural soils. As, Hg, Cd, Pb, Cu, and Zn exhibited large spatial differentiation and were significantly affected by the external environment. A regional pollution load index of 3.02 indicated overall heavy pollution. The pollution load index for each heavy metal(loid) indicated light pollution. The geoaccumulation index indicated relatively severe As, Cd, Cu, Pb, and Zn pollution. The Nemero Composite Pollution Index value showed that the study area was heavily polluted, with construction land being mildly polluted by Cd, and agricultural land being moderately polluted. The results of the spatial distribution show that there were high levels of contamination in the center. Correlation and principal component analyses showed that the pollution sources of the eight heavy metal(loid)s varied. Hg, Cd, and Pb originate primarily from industrial and agricultural pollution. Traffic sources significantly impacted Cu, Pb, Cd, and Cr. Natural sources are the main sources of Cr, Ni, and Cd. Ni is also affected by industrial sources, whereas Zn and Cu are affected by agricultural pollution. The influences of As, Cd, and Pb on the surface soil in the study area were more serious. Cd is more widely polluted and should be a priority in controlling soil heavy metal(loid)s.

Résumé :

Introduction. The paper presents the results of a study of environmental and hygienic assessment of soils in urban administrative centers of the Vladimir region for the content of heavy metals and arsenic. Materials and methods. The object of research is the upper horizons of urban soils in eighteen administrative centers of the Vladimir region. Soil samples were taken in the summer of 2022-2023 in various functional zones of cities. The soil cover was studied using the X-ray fluorescence method to determine the content of heavy metals and arsenic. Results. The maximum, minimum, and median values of concentrations of heavy metals and arsenic in the soils of the administrative centers of the region were established. Soil contamination with heavy metals and arsenic across cities is characterized by significant differentiation. The highest concentrations of pollutants were recorded in urban soils of industrial zones, the minimum – in landscape and recreational zones. The priority soil pollutants in the cities of the Vladimir region are As and Pb. The maximum values of the total indicator of soil pollution were identified in such cities as Gus-Khrustalny, Kovrov, Melenki, which makes it possible to classify them as extremely dangerous. The city of Suzdal turned out to be the most favourable in terms of soil pollution, positioned primarily as a historical and tourist center, in which there are practically no industrial enterprises. Limitations. The calculation methodology, which is focused on soil types and their granulometric composition, which differ in different administrative centers. Conclusion. An assessment of the contamination level of urban soils in the administrative centers of the Vladimir region in terms of the content of heavy metals and arsenic showed the majority of the urban population to live in an area with soils of a moderately hazardous and permissible category. The maximum values of the total indicator of soil pollution are associated, first of all, with abnormal local technogenic chemical pollution caused by the activities and specifics of industrial enterprises using heavy metal compounds in technological processes. The likelihood of high risks to public health and the environment of the urban space of the administrative centers of the Vladimir region determines the need to manage constant environmental and hygienic monitoring of their soil cover, since soil pollution may result in a deterioration in the safety and comfort of the living environment of urban residents.

Résumé :

Modern swine has been notable for growth in the last decades, however, the intensification of pig farming has been causing great environmental problems, evidencing the pollution of natural resources such as air, soil and water. In regions with high concentration of farms, most animal waste is released to the soil and water courses without criteria or prior treatment, becoming an important source of environmental pollution. When waste is properly managed, it is no longer polluting and becomes a valuable source of fertilizer, as well as preserving and improving the physical, chemical and biological properties of the soil, avoiding the use of petroleum-based inputs that are highly energetic and expensive. In our country several methods are used for the handling and treatment of waste, each of which has its own particularities. This paper deals with the environmental impacts caused by the irrational disposal of industrial swine residues and presents the legal techniques of treatment of swine manure, aiming at its reuse with higher agronomic value.

Résumé :

Heavy metal pollution has been a problem of concern in soil ecology in recent decades. This study investigated the spatial distribution of heavy metals and their pollution levels in the soil of Xinjiang, based on the data of heavy metals published in the literature in the past five years, by using a geostatistical method, pollution index method, and geographic information system (GIS)-based spatial analysis. Additionally, the effects of five economic development indicators, such as population and industrial activities on the accumulation of heavy metals in soil, were explored by correlation analysis. The results showed that the average contents of Cd, Cr, Cu, Ni, Pb, and Zn in the soils were 2.858, 1.062, 1.194, 1.159, 1.192, and 1.086 times higher than the background values in Xinjiang, respectively. The semi-variance functions indicated that the Cd and Pb block gold coefficients of soils were greater than 25% and less than 50%, with an obvious spatial correlation. The spatial patterns showed that the high values of Cd, Cr, Cu, Ni, Pb, and Zn were mainly distributed in Karamay, Changji, Tacheng, and Kashi areas, with an overall decreasing trend from north to south, and the pollution index showed that the pollution of heavy metal Cd in soil was the most serious. Furthermore, Karamay, Changji, and Kashi areas were at heavy pollution levels. Correlation analysis showed that heavy metal Pb in the soil was significantly positively correlated with the agricultural GDP in Xinjiang, while Cd was correlated significantly and positively with comprehensive energy consumption and more significantly with industrial GDP. Thus, this study could provide a scientific basis for local evaluation of soil environmental quality and prevention and control of soil heavy metal pollution, which is of great significance for understanding the impact of human activities.

Résumé :

The concern about industrial pollution and food safety is growing due to crop contamination and a major route to human exposure. The experiment was completed at a net house of Sher-e-Bangla Agricultural University during November 2021 to April 2022 to find out the effect of industrial soil pollution and fertilizer management on growth, yield and metal accumulation by BARI Tomato 8. Industrially polluted soils were collected from contaminated areas considering the soil pollution intensity. The physico-chemical properties were determined in soils. The experiment consists of two-factor, as Factor A: Six different soils (S0: Non-polluted soil; S1: Polluted soil-1, S2: Polluted soil-2; S3: Polluted soil-3, S4: Polluted soil-4 and S5: Polluted soil-5) and Factor B: Three fertilizer treatments (T0: Control; T1: 100% soil test basis dose of fertilizer; T2: 50% soil test basis dose of fertilizer and 50% nutrient from cowdung). High yielding tomato variety BARI Tomato 8 was used for experiment. Among the soils, the highest tomato yield was found in S1 and S5 polluted soils, while the lowest was obtained in S4 and S0 soils. The highest tomato yield was recorded in T2 treatment and the lowest in T0 treatment. The highest tomato fruit dry matter, Pb (1.359 mg kg-1) and Cd (0.759 mg kg-1) concentrations were found in T0 treatment and the lower levels were obtained in T1 (100% RDCF) and T2 (100% RDCF + 50% nutrient from cowdung) treatments. The higher tomato Pb and Cd concentrations were recorded in polluted soils with T0 and T1 treatments and the lower with T2. The highest tomato Pb concentration (1.656 mg kg-1) was obtained in S4T1 and the lowest (0.501 mg kg-1) in S3T2. The highest tomato Cd concentration (1.149 mg kg-1) was obtained in S5T0 and the lowest (0.097 mg kg-1) in S2T2 treatment combinations. J Bangladesh Agril Univ 22(4): 404–411, 2024

Résumé :

Few studies have been done on temporal changes of heavy metal pollution of urban soils. Eight soil samples at the same sites were collected inKaifengCity, China, in1994and 2006. Concentrations of Pb, Cd, As and Hg in the samples was measured. The pollution change of heavy metals from 1994 to 2006, and the relations between metal pollution and some human factors were discussed. The results show that soil pollution with metals in 2006 was higher than that in 1994 with economic growth. Soils in industrial district (ID) were more strongly polluted than in the following districts: (i) cultural and educational district (CED), (ii) mixed district of resident-commerce-administration (RCD), (iii) recreational district (RD), and (iv) suburban district (SD). Cd and Hg were the dominant pollutants. Economic growth, changes of land use and land-use authority can influence soil metal pollution significantly.

Résumé :

Farmland soil quality is a crucial determinant for agricultural productivity, food safety, and human well-being. Among the various contaminants, heavy metals have emerged as pervasive factors significantly impacting farmland quality, attracting widespread societal concern. In this study, we systematically applied multivariate statistical analysis, geostatistical methods, and the positive matrix factorization (PMF) source apportionment technique to elucidate the sources and contributions of eight heavy metals (Cd, Hg, As, Pb, Cr, Cu, Zn, Ni) in farmland soils within an industrialized town. Our findings reveal that Cd, Hg, Pb, and Zn exhibit pollution or enrichment in farmland soils compared to natural background levels, with Hg and Cd surpassing 164.3% and 50.2%, respectively. Notably, Zn demonstrates discernible point-source pollution. Source apportionment results highlight industrial point sources, coal combustion, and agriculture as the primary anthropogenic contributors to heavy metal contamination, with zinc-plating enterprises being the predominant industrial point sources. Addressing the specific issue of point-source pollution from Zn in industrial activities, further analysis establishes a correlation between soil Zn content and the distance from zinc-plating enterprises. Utilizing an atmospheric transport model, we observe that the impact of industrial activities on soil Zn is limited when the distance exceeds 1.5 km, emphasizing the importance of monitoring Zn pollution within areas less than 1.5 km. This study pioneers a progressive source apportionment approach, considering the origins of different heavy metals, pollution levels, distance factors, and the cost-effectiveness of environmental measures. The insights gained provide scientifically sound strategies for future decision making in environmental protection.

Résumé :

The article considers that the course of more than 5 decades as a result of the infiltration of contaminated waters of open pits, dumps, slag accumulators of the copper smelting plant (CSP), the production association (PА) "Ammophos", tailing dumps of copper concentrating factories (СCF -1 and СCF -2), as well as due to the leakage of reagents from the sulfuric acid shop through rocks that are not consistent in area and insignificant thickness of loess-like loams, and the penetration of polluting components into the aquifer occurs. Due to the action of the infiltration flow, a change in the chemical composition of soils occurs on solid soil particles, a number of chemical compounds are sorbed. The article provides recommendations for reducing the pollution of the geological environment.

Résumé :

Industrial effluents, containing heavy metals, drain directly into downstream water sources within the Hawassa Industrial Zone. These, water sources are used for irrigation, drinking water and other domestic purposes. The load of pollutants, environmental risks and potential human impacts are generally, unknown for soil in Ethiopia. Therefore, the aim of this study was to determine the extent of heavy metal pollution of soil within the Hawassa Industrial Zone and to evaluate environmental impacts using contamination factor (CF), degree of contamination (Cd), modified degree of contamination (mCd), ecological risk factor (Er), ecological risk index (ERI) and pollution load index (PLI) analyses. Seven heavy metals: Cr, Ni, Cu, Zn, As, Cd and Pb were determined in soil samples from three different sites by inductively coupled plasma mass spectrometry (ICP-MS). Average concentration of metals decreased in the order of Zn>Cu>Cr>Ni>Pb>As>Cd consistent with the normal order of abundance in non-polluted soils. One way ANOVA revealed significant differences (P<0.05) in the concentrations of Cu, As, Cd and Pb among the sampling sites. Pearson’s correlation, principal component and cluster analyses revealed that heavy metals are originating from different sources. Within the industrial area, the CF increased in the order of Pb<Cd<Zn<As<Cu<Cr<Ni. The result of Cd revealed that there was considerable to very high contamination of the soil. The mCd index showed moderate contamination of the soils. The Er increased in the order of Zn<Cr<Pb<Cu<Ni<As<Cd and the result of the ERI value revealed considerable ecological risk for the soils. Overall, the study showed that the soils within the Hawassa Industrial Zone are highly contaminated with heavy metals. Therefore, regular monitoring of heavy metals concentration in soil and policy interventions with respect to waste disposal are recommended.

Résumé :

The potentially toxic element pollution of agricultural soils has become a significant environmental threat to food safety and human health. Accurately identifying sources of potentially toxic element pollution is key to developing effective pollution prevention and control measures. In this study, regional potentially toxic element pollution of the soils in the Nanliujiang River Basin was analyzed using the positive matrix factorization (PMF) model and the geo-detector model. First, topsoil samples from the study area were collected to analyze eight potentially toxic elements in the soil, including As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn. The PMF model was used to conduct source apportionment of the potentially toxic element data and identify the primary pollution sources and their contribution rates. Then, the geo-detector model was used to analyze the key factors affecting the spatial distribution of the potentially toxic elements and the influence of natural and human factors on the distribution of the potentially toxic elements. There are four potentially toxic element pollution sources of the agricultural soil in the study area: geological background, agricultural activities, industrial discharge, and river irrigation. The geological background contributed the most. The main factors affecting the spatial distribution of potentially toxic elements included agricultural activities, industrial discharge, and river irrigation. This integrated method can analyze the formation of potentially toxic element pollution in depth from the perspectives of source apportionment and spatial differentiation and provide a scientific basis and decision support for preventing and controlling potentially toxic element pollution in agricultural soils. This study provides a new method and scientific basis for identifying and preventing potentially toxic element pollution sources in agricultural soil and can guide the formulation of targeted soil pollution control measures.

Résumé :

With the rapid development of urbanization and industrialization in China, whether the abandoned industrial land can be reused has become the focus of land planning. So soil environmental quality assessment on the abandoned land is necessary. In this paper, the land of a discarded chemical plant in Chongqing, China was chosen as the study object. The concentrations of heavy metal were studied. Single Factor Pollution Index (SFPI) and Integral Pollution Index (IPI) were applied to assess the degree of soil pollution. The results revealed that the abandoned industrial soil in this work was slight polluted and could only be planned for the 2nd type of land utilization, including green land, commercial land, public facilities land, etc.

Résumé :

Concentration of 2 heavy metals; lead and mercury (Pb and Hg) in rivers and sediments soil were studied at different sites in Basrah. In this study, the effect of lead and mercury pollutions is studied together with determining their locations in the surface water and sediments at some areas in the South of Iraq (Basrah Governorate) particularly in the upper areas of the Arabian Gulf and in its northern part. These seven locations are: Qurnah, Madinah, Deir, Ashar, Abo Alâ€“Khasib, Zubair and Um Qasir. The effect of the lead and mercury concentration on surface water and sediments analysed during 2014-2015 quarterly. Standardized method have been followed in analysing and comparison the surface water standards and sediment soil just to determine the percentage of lead and mercury pollution and assesse the values with standard pollution index. Overall concentrations of Pb in the rivers ranged from 0.44-4.5 mg/l for surface water and soil sediment samples ranged from 0.0-7.36 mg/kg, and for Hg in the rivers from 0.0003-0.006 mg/l and soil sediment samples ranged from 0.0005-0.009 mg/kg. The concentration of heavy metals in the surface water and soil display the following decreasing trend: Pb>Hg. From this result, found that levels of heavy metal in surface water and soil near industrial areas give higher value compared with other locations in Basrah. The Pollution index revealed that Pb and Hg give low contamination. The highest concentrations values are recorded in Abo Al-Khasib (7.63 ppm) for the underground sediments, the lowest concentrations values are recorded in Madina for the depth sediments. The highest concentrations are recorded in Al-Deer (0.009 ppm) for the mercury pollution. Results of combined heavy metal concentration and heavy metal assessment indicate that industrial activities and traffic emission represent most important sources for Hg and Pb. The pollution Index were calculated for the two pollutants concentrations at the rivers and soils.

Résumé :

Abstract The problem of soil contamination around industrial areas in recent years might be due to arbitrary industrialization, unproper irrigation practices, modern industrialization practices, and the indiscriminate use of fertilizer and pesticides that contribute to environmental degradation. Such anthropogenic activity always results in depletion of soil and water quality, such as deterioration of soil quality and pollution of soil and surface water, which result in a variety of health hazards. Therefore, there is a need to study a comprehensive approach to land quality issues in industrial areas. In this study, contamination indices and soil quality guidelines were used to evaluate the contamination status of soils around the Pasir Gudang industrial area. Soil samples were collected at the selected locations near industrial, riverside, residential, and educational areas. The data generated in the current study will be very useful for safe monitoring of the area by authorities and planners in land resource management.

Résumé :

This study assesses heavy metal (HM) contamination in soils of an urban industrial zone using statistical and spatial analysis methods. Concentrations of 12 key HMs, including Zn, Pb, Cu, and Ni, were measured using X-ray fluorescence (XRF), with values exceeding background levels several times in certain areas. Pollution indices such as the Pollution Load Index (PLI) and Total Pollution Indicator (Zc) revealed moderate to high contamination levels, with PLI values ranging from 1.05 to 3.38 and Zc values between 0.67 and 51.34. Health risk assessments indicated that the hazard quotients (HQ) exceeded safe thresholds in hotspots, highlighting potential risks. Spatial distribution maps identified industrial activities as the primary source of contamination. Specifically, according to the PLI, approximately 93.757% of the studied area is classified as moderately contaminated, while 0.702% is considered significantly contaminated. These findings provide a baseline for monitoring and mitigating soil pollution in industrial regions while offering insights for sustainable land management.

Résumé :

Samara Region is one of the largest industrial and agricultural centers of the Russian Federation. It is characterized by a high level of urbanization. Soil degradation, its chemical and bacteriological pollution as well as declining fertility are the result of versatile economic activity in the region. The rate and level of soil pollution are actively monitored however only very scarce data on its sanitary-epidemiological condition are available. At present Samara Region is facing a boost of residential, administrative and industrial constriction which requires sanitary-epidemiological testing of soil at construction sites. The paper deals with the above mentioned problem. It has been determined that the most reliable criteria in estimating the sanitary-epidemiological condition of soil are sanitary-significant microorganisms, a group of coliform bacillus in particular. The causes and effects of urban soil pollution by microbiological contaminants have been analyzed. The role of lactose-positive intestinal protozoa as sanitary-significant microorganisms has been studied. A quantitative evaluation of lactose-positive intestinal protozoa index has been carried out for the soils below residential buildings, administrative buildings, industrial constructions as well as the utility systems area. In particular, it has been measured that the level of soil pollution by lactose positive intestinal protozoa depends on the period they have been in human use. An aggravated level of soil pollution in certain areas can be observed due to uncontrolled littering as well as pet walking or an increasing number of stray animals. Industrialized areas (oil plants) are characterized by the lowest level of lactose positive protozoa contamination which is explained by the fact that those industries use modern technologies which are able to minimize ecological risks. However, such areas are polluted in a different way. Dangerous level of soil contamination by lactose positive protozoa is registered at several large automotive plants.

Résumé :

Many rivers throughout Bangladesh are now under threat due to both human-made and natural causes. In this context, we describe the Buriganga river system, its uses of the river, its level of pollution, and its sources of pollution. The present condition of the Buriganga water and its surrounding areas soils and plants might not be suitable for fisheries and irrigation; it has been observed that sampling points of 9,10,11 were highly polluted, with sampling point 7 with the highest water pH value (7.19), in sampling point 11 EC value was found (799 μS/cm) with other physicochemical parameters and Fe, Cd, Cr and Zn content in plant and soil samples were comparatively high at sampling point 9 and 11. In the studied area, the correlation coefficient of heavy metal content among soil and water, the Cr concentration (0.0289mg/l), was highly significant; it has been indicated that heavy metals were uptake by soil.
