Full textAbstract:
This issue of Mineralogical Magazine is the 5th in a loosely defined series of special thematic issues (or part issues), deriving from conferences organized by the Mineralogical Society. The associated conference was entitled ‘Environmental Mineralogy, Geochemistry and Human Health’ and took place in January 2005, in Bath. A common thread to all these Mineralogical Society conferences has been the role of mineralogy in applied science and technology and particularly in environmental science, focussing on the multidisciplinarity of modern mineralogy; the conferences (and special issues) have been particularly successful in bringing along scientists from outside traditional Mineralogy/Earth Sciences. Notably, the series comes at a time when the popularity of Mineralogy/Geology, but also science in general, is low, and many, particularly young, scientists are seeking to place themselves in a better position in the eye of the public and the media, and often also to find new focus for their research. A primary ambition for the series is thus to demonstrate Mineralogy's extensive outreach and has so far succeeded in giving the scientific community a sense of the wider role mineralogists can play.

<p>At present, all countries in the world attach great importance to the development and application of remote sensing technology, which is widely used in many fields. By means of detection methods, this technology combines physics knowledge and modern network technology to provide relevant information for human exploration of geology, atmosphere, ocean and weather. In recent years, the global economy has developed rapidly. However, the environmental pollution has become increasingly serious at the same time. Industrial enterprises have discharged a large number of pollutants, resulting in air pollution, water pollution, soil pollution and so on, which seriously endanger human health and life safety. Environmental monitoring is the basis of effective control of environmental pollution. Remote sensing technology can be applied to carry out environmental monitoring and improve the monitoring effect of environmental monitoring.</p>

Coccidioidomycosis (CM) is a disease of major public health importance due to the challenges in its diagnosis and treatment. To understand CM requires the attributes of a multidisciplinary network analysis to appreciate the complexity of the medical, the environmental and the social issues involved: public health, public policy, geology, atmospheric science, agronomy, social sciences and finally humanities, all which provide insight into this population transformation.In section 1 of this paper, we describe the CM-epidemiology, the clinical features, the diagnosis and finally the treatment.In section 2, we highlight the most important contributions and controversies in the history of the CM-research by using scientometric or bibliometric evaluations of research that are based on Garfield’s work (Garfield.library.upenn.edu) on the propagation of scientific thinking.

Abstract Increased concern over the contamination of surface waters by road salts and their adverse effects on the freshwater organisms led to the inclusion of “road salts” on the second Priority Substances List (PSL2) under the Canadian Environmental Protection Act The list identifies substances that must be assessed on a priority basis to characterize the nature and extent of the risk they pose to the environment or human health. This paper adds to the collection of several reports which constitute “supporting documentation” for the environmental risk assessment of the priority substance “road salts”. It reviews the physical-chemical properties of inorganic salts commonly used for road maintenance and their fate and transport in surface waters and sediments, together with the environmental concentrations of road salt constituents in the context of watershed geology and other environmental factors governing their concentrations. The paper also provides a spatial map of chloride concentrations as a basis for developing an understanding of a spatially based, ecological risk assessment for surface water systems and relates the spatial risk map to observed concentrations of chlorides. The data suggest that the surface waters most sensitive to road salts impacts are small ponds and streams draining large urbanized areas. Environment Canada is presently considering several alternatives for dealing with road salts.

Large-scale mining activities have a huge impact on the environment. Determination of the size of the effect and monitoring it is vital. In this study, risk assessment studies in mining areas and the effect of mining on groundwater and ecosystems were investigated. Best management practices and risk assessment steps were determined, especially in areas with huge amounts of mining wastewater. The pollution of groundwater and its reaching humans is a risk of major importance. Our study showed, using many cases with different parameters and countries, that the management of mining wastewater is vital. Environmental impact assessments and monitoring studies must be carried out before operation and at the closure of the mine. Policies must be in place and ready to apply. Factors of climate, geology, ecology and human health must be considered over a long period. Currently, only the developed countries are applying policies and paying attention to the risk. International assessments and health risk assessments should be carried out according to international standards.

Full textAbstract:
In the area of study the quality and quantity of groundwater are below the normal standards. In this study spatial statistical methods have been used to demarcate highly polluted zones. Especially fluoride concentrated areas in Nalgonda district. Water quality, especially excess of fluoride concentration in groundwater, is a major concern in the study area. Levels of fluoride in groundwater are considerably greater than the permissible limit especially in Nalgonda district which is known for endemic fluorosis, which is caused by intake of high fluoride water is a slow, progressively, crippling malady affecting young and old, poor and rich, rural and urban population. The area under investigation lies in between the longitude 790 0'-79o 30' E and latitude 16o 45'-17o 15' N. In as many as 1122 habitations in Ranga Reddy and Nalgonda districts, fluorosis is prevalent and they have fluoride content in excess of 1.5 mg/l drinking water. One such area where fluoride contamination in groundwater has been known for several years in parts of Nalgonda district of Telangana state. In this district, several thousands of people in various villages are suffering with advanced fluorosis. A number of studies carried out earlier established the extent of fluoride contamination in different villages. However, no attempt was made to study the spatial distribution of various quality parameters including fluoride in the groundwater of this area. With this background this investigation is planned and undertaken. The spatial variability of groundwater G.I.S techniques were presented. The fluoride variation with reference to other quality parameters was brought out. An attempt is being made to summarise and understand the factors that control the groundwater quality variation in the area of study. A detailed study on fluoride occurrence is taken up, mainly to see its relationship with various other parameters and the influence of hydrogeology and lineament pattern on fluoride occurrence.

Full textAbstract:
In Viet Nam, non-sulfide zinc ore in the Cho Dien deposit has been exploited for a long time. Up to the present, zinc ore remains the major exploited ore in Cho Dien. There are numerous studies of Pb-Zn ore in Cho Dien. However, most of the studies have dedicated only to description of mineralogical and chemical composition of Pb-Zn ore. There has been no publication on this non-sulfide zinc ore. Based on the mineralogical studies, the content of Pb and Zn in groundwater determined by reflective microscope, SEM, EPMA and ICP-MS methods, the study explained the formation of secondary non-sulfide zinc ore in the Cho Dien deposit. Strong weathering process makes the upper part of ore bodies completely oxidized. Difference in geochemical behavior of lead (Pb) and zinc (Zn) in the oxidation process of Pb-Zn ore is the reason to form non-sulfide zinc ore in the Cho Dien deposit. Oxidation of primary Pb-Zn ore is mainly sphalerite, pyrite, galena minerals which creates a low pH environment and transforms of zinc from immobile (sphalerite - ZnS) to mobile (Zn2+) and retained in solution under acid pH conditions whereas lead has the tendency to form soluble minerals (anglesite, cerussite). The acid neutralization actions of the surrounding rocks make zinc precipitate, to form secondary non-sulfide zinc minerals.ReferencesAndreas Nuspl, 2009.

Full textAbstract:
ABSTRACT The U.S. Environmental Protection Agency (EPA or the Agency) has prepared revised guidelines on discharging oil into U.S. waters to assist research efforts on the prevention, preparedness and response to oil pollution that cannot be conducted in a laboratory, test tank, or other facility. The revised guidelines update the 1971 guidelines developed for the same purpose. Under these guidelines, the applicant for an oil discharge permit should; 1) provide data on the methods used to assess the environmental effects of the proposed test; 2) provide information and demonstrate (if possible) that the proposed test site has been selected to minimize adverse environmental impacts; 3) assess the potential impacts of the proposed test on the aesthetic, recreational, and economic uses of the proposed test site; 4) address potential impacts to public health; 5) describe how expected environmental effects will be controlled; 6) provide an opportunity for public participation in the permitting process; 7) provide a detailed description of the proposed test site; and 8) include a description of the geology, hydrology, water quality, ecology, climatic and any other environmental factors that could effect the petroleum discharge and the site. EPA recognizes that bench- and meso-scale testing has prompted interest in field testing (using intentional discharges of oil) on a larger scale than was contemplated when the original guidelines were issued in 1971. The Agency has, therefore, removed the 1,000-gallon upper limit on the size of the permitted oil discharge in the original guidelines. The Agency is aware, however, that the discharge of greater volumes of oil will require correspondingly greater efforts to protect the public health and environment. EPA will therefore closely examine the justifications for large-volume discharge applications (greater than 1,000 gallons) to determine whether the proposed discharge size is justified.

Full textAbstract:
SUMMARYThe prohibition of commercial mineral resource extraction through the Antarctic Treaty System has removed one significant source of potential damage to Antarctica's geological and geomorphological values. However, given the on-going increase in Antarctic tourism and scientific footprint, some high-quality geological features may be vulnerable to human impact, such as damage due to the construction of logistical facilities, unregulated collection of geological specimens or oversampling for scientific purposes. The Protocol on Environmental Protection to the Antarctic Treaty puts in place a framework for the protection of Antarctica's environmental, scientific, historic, wilderness and aesthetic values. However, the Antarctic Protected Area system is still immature and further implementation of existing management tools may be required to protect the diverse range of vulnerabilities, qualities and spatial scales represented in the geology and geomorphology of the continent. At sites where high-quality mineralogical or palaeontological specimens exist in limited quantities, considerations of how best to prevent oversampling and manage access to remaining material may be supported by assessment of cumulative impacts. Examination of the level of Antarctic specimen loans from a selection of national geological collections suggested that existing publically accessible geological collections could be better utilized, which could reduce environmental impact and oversampling at vulnerable Antarctic sites.

The scientific community has been concerned about heavy metals contamination and their effects on human health and the environment. Rural areas of Descoberto municipality, southern Minas Gerais State, were submitted to gold extraction using rudimentary techniques of mineral processing. In 2002, local population detected metallic mercury presence on soil surface, and in 2005 Environmental Foundation of Minas Gerais State (FEAM) delimited a critical contamination area. This works proposes bioavailability assessment of mercury (Hg), zinc (Zn) and copper (Cu) in distinct grain sizes of a soil sample collected into the critical area delimited by FEAM. Granulometric analysis was done using nylon sieves of 200 # (75 µm), 100 # (150 µm), 80 # (180 µm), 42 # (350 µm) and 10 # (1700 µm). Mineralogical characterization was executed using X-ray difratometry. Earthworms acute toxicity test follows ASTM (2004) procedures. Metals determination in soil and earthworms was performed using Atomic Absorption technique. Methylmercury (MeHg) quantification was made using Gas Chromatography. Grain sizes analysis showed sand predominance. Total chemical analysis demonstrated a very high level of contamination of Hg, Zn and Cu, confirming previous studies executed by FEAM. It was observed an affinity between grain size and metals concentrations, which is related to increasing specific surface. Acute toxicity test denoted that earthworms absorbed Hg and Cu from the soil, and Zn uptake involved absorption and bioaccumulation for smaller grain sizes. Total chemical analysis of metals in earthworms revealed that finer granulometric intervals showed higher levels of heavy metals bioavaibility. MeHg quantification denoted concentrations about 21 a 33% of total Hg. In conclusion, it is expected that these results can give an important support for future decisions in medical geology programs and in environmental control actions

Coal mining is an integrated trade which involves the geology, well ventilated, transportation, electricity and environmental protection and so on. The mining industry has labor intensity, bad work condition, many harm factors. Each kind of virulent noxious gas, coal dust, fire, electromechanical device are all immediate danger to operate personnel's safety and healthy. Well-balanced and suitable ventilation is the postulate to keep the health of underground worker and the safety of the production. We take air quantity of laneway as the research emphasis, considering the release of state regulations on coal min. We figure out the optimum area of air quantity via building the optimization programming model, and realize an actual case study to interpret the process of the probabilistic risk analysis (PRA) with statistic theory. We take the theory to the actual production. We establish a MIS base on the theory. In the process of establishing the system, we use the object-oriented analysis method and the B/S structure, take JAVA as the development kit, and realize the risk analysis system. Then the risk manager can take the corresponding monitoring measure.

Road-traffic-noise exposition is widespread in Germany and can have harmful health effects. As guidance for informed decision-making, we estimated the environmental burden of disease attributable to road-traffic noise in Hesse, Germany as disability-adjusted life-years (DALYs). Using detailed road-traffic-noise exposure data provided by the Hessian Agency for Nature Conservation, Environment, and Geology (HLNUG), we calculated the DALYs due to road-traffic noise > 40 dB(A) L24h (unweighted average 24 h noise level) and other noise metrics for endpoints with known dose-response functions and evidence in the literature (NORAH-study on disease risks and WHO reviews): cardiovascular disease, depressive disorders, road-traffic annoyance, and sleep disturbance. We calculated the population-attributable fractions (PAF) for road-noise-related cardiovascular disease (hypertensive heart disease, ischemic heart disease, and stroke) and depressive disorders in the population using published relative risk estimates. We multiplied the PAFs with the Hessian proportion of the 2015 WHO DALY estimates for Germany in people aged ≥ 40 years. For high annoyance and high sleep disturbance, we used published dose-response functions to determine the burden for residents of all ages. For Hesse, we found a total of 26,501 DALYs attributable to road-traffic noise or 435 DALY per 100,000 persons for the reference year, 2015. Further, we estimated that a hypothetic uniform road-traffic-noise reduction of 3 dB would prevent 23% of this burden of disease.

This study presents an overview about the arsenic (As) contamination and its sources in two European countries. Arsenic is a highly toxic element in its inorganic form and it is carcinogenic to human seven in low concentrations. The occurrence of As in surface water, stream and marine waters, groundwater, bottled water, sediment, soil, mines, and seafood, its environmental origin, and its impacts on human health are discussed. The classes of Geoaccumulation Index for As in Greece ranges from practically uncontaminated to extremely contaminated, and in Cyprus varies between practically uncontaminated and heavily contaminated. In many cases, the As contamination reaches very high concentrations and the impacts may be crucial for the human health and ecosystems. Physicochemical properties, regional climate and geological setting are controlling the occurrence and transport of As. In Greece and Cyprus, the geology, lithology, and ore-deposits are the most important factors for the variation of As contents in water, soil, and sediment. The dominant As species are also determined by the location and the redox conditions. The findings of this paper may be useful for scientists and stakeholders monitoring the studied areas and applying measures for protection of the human and terrestrial ecological receptors (plants, avian, mammals).

Full textAbstract:
Rainfall and river flows are environmental variables influencing the microbial status of bivalve mollusc harvesting areas. This study investigated spatial and temporal relationships between rainfall, river flows and concentrations of Escherichia coli in mussels (Mytilus spp.) and Pacific oysters (C. gigas) from three harvesting areas in the Dart Estuary over the period 1996–2009. Mussels growing on the riverbed were found to be more contaminated than oysters growing in the water column. A step change in the levels of the microbial indicator was identified in both species from all harvesting areas. The highest levels of E. coli were detected when total rainfall exceeded 2 mm and water levels in the main tributaries exceeded the mean flow. The magnitude of response in levels of E. coli to these hydrological events varied between species and monitoring points, but was consistently higher between the 3rd and 4th days after the rainfall event. This lag time is assumed to result from catchment topography and geology determining peak levels of runoff at the headwaters 12–24 h after rainfall events. It is considered that future risk management measures may include sampling targeting hydrograph events.

Hence this study set out to assess the lead soil content in four different sites of Kabwe district, Central province of Zambia. Literature was reviewed from studies that covered soil lead contamination. a quantitative analytical study was carried out and it involved geographical mapping of four different sites the north, South, East, and West of Kabwe district which were conveniently selected to collect soil Samples which were taken to The University of Zambia School of Mines, Geology Engineering Laboratory to determine the Levels of soil Lead content using a technique called Geo-Chemical Analysis. The results suggest that Chowa area is highly polluted with lead metal according to the globally recommended WHO guidelines and Zambia Environmental Management agency which all states that Residential areas should not exceed 400Kg/mg or parts per million.

Full textAbstract:
The harmful health effects of airborne particulate matter (PM) pollutants are well-known. However, the spatial coverage of automated air quality observation stations of Latvian Environment, Geology and Meteorology Centre (LEGMC) is sparse. Therefore the capability for PM concentration detection was examined by using the low-cost optical PM sensor to improve the spatial resolution of environmental data. The aim of the study was to perform 24h/7d measurements of PM2.5 and PM10 concentrations during a period of one year and to identify air quality in Esplanāde housing estate, Daugavpils city. For data obtaining on the concentration of PM2.5 and PM10 particles measurements have been performed by optical sensor Nova SDS011; meteorological data were obtained using the database of LEGMC; for processing, analysis and visualization of obtained data statistical methods were applied. Evaluation of PM2.5 and PM10 daily average concentration variability in 2020 indicates that air quality in the urban environment could be assessed as good. A well-expressed statistical correlation between meteorological factors (t°C, relative humidity) and the average concentration of PM particles was not found. It highlights the necessity of further research.

The healthy water resources are necessary and essential prerequisite for environmental protection and economic development, political, social and cultural rights of Iran. In this research, water quality parameters i.e. total dissolved solids (TDS), sodium absorption rate (SAR), electrical conductivity (EC), Na+, Cl-, CO32-, K+, Mg2+, Ca2+, pH, HCO3- and SO42- during 2010-2011 were obtained from Iranian Water Resources Research Institute in water quality measurement stations on Mazandaran province, Iran. Then, the most important catchment characteristics (area, mean slope, mean height, base flow index, annual rainfall, land cover, and geology) were determined on water quality parameters using stepwise regression via backwards method in the 63 selected rivers. The results showed that sodium absorption rate (SAR), total dissolved solids (TDS), electrical conductivity (EC), Na+ and Cl- parameters are strongly linked to geology characteristics, while K+, Mg2+ and Ca2+ cations is linked to rainfall and geology characteristics. pH and HCO3- are related to area, rainfall, land cover and geology characteristics, CO32- is related to area, rainfall, rangeland area and geology characteristics and SO42- is related to area, rainfall, range and bar land area and geology characteristics. Adaptive Neuro-Fuzzy Inference System (ANFIS) was used for modeling the selected catchment characteristics and water quality parameters. The ANFIS models have a high Nash–Sutcliffe model efficiency coefficient (NSE) and low root mean squares error (RMSE) to estimate water quality parameters.

In recent decades, the pace of industrialization has caused an number of environmental problems. A considerable increase in the global energy demand is one of the most important problems in today’s world. In fact, fossil fuels are the main source of energy triggering the release of huge amounts of greenhouse gases into the atmosphere. Many efforts have been made by researchers to come up with different strategies to mitigate the global consequences of greenhouse gas emissions such as global warming. One of these strategies is to reduce the amount of greenhouse gas emited into the atmosphere. This study aims to select the appropriate sites for carbon dioxide underground storage facilities. The selection of the best sites for CO2 underground storage is very important from various perspectives of sustainable development to accelerate the commercialization of such facilities. In this regard, fuzzy-Delphi methodology was used to prioritize the most important criteria in the CO2 storage process. Nineteen sub-criteria were selected in the technical, health, safety and environmental (HSE), economic and social categories. Specialist questionnaires were prepared, considering all relevant scientific and technical aspects, and experts in the field were invited to participate in the survey. The results were analyzed using SPSS 25.0. According to results, Geology and Lithology, Caprock Permeability, Social Acceptance, Depth, Reservoir Permeability, and Porosity were determined as the highest priorities. Based on the results achieved, it can be concluded that technical criteria are of the highest importance in the site selection of underground carbon dioxide site selection facilities.

Full textAbstract:
The Malekhu Khola is accessible and potential for the construction materials in today’s developing phase. The study mainly concerns with mining of construction aggregate and effect of indiscriminate mining from river and its basin area which may impose many harmful effects on environment. The objective of the study is to identify the condition of river using morphological and physical parameters, and to investigate the factors which are directly responsible for the environmental degradation. Such study of rivers in present context is essential as it provides insights of strength of the river. To examine the circumstance of river, the study was proceed by selecting the area into three reaches of each 500 m, and further each reaches are divided into six transects. Both reach-scale and transect-scale attributes were assessed. The scoring was done by adding all the attributes of the standard survey sheet. A cross-sectional study was carried out along 3 different stations, Reach 1 to Reach 3 from upstream to downstream. Various fluvial parameters and data from pebble count were used to calculate morphological parameter and grain size distribution. The channel sediments were found to be extremely poorly sorted, the distribution of grain size is varied from transect to transect, which might be the result of unplanned mining. All the result acquired from field study and satellite image confirms that the river is worsening day by day. The formation of pools and deposition of organic matter show that the river is not flowing in its natural way. After all the examination, it indicates that the Malekhu Khola is being violated by the human and mining activities, thus the river reclamation measure is required at abandoned mining sites to maintain the Malekhu Khola channel morphology and habitat of the river.Bulletin of the Department of Geology, Vol. 18, 2015, pp. 59-66

Full textAbstract:
The main scope of this study was to remediate Acid Mine Drainage (AMD) by application of biohydrometallurgical processes, environmentally friendly, to remove heavy metals such as Zn, Cu, Mn, Cd, Al and Fe. The processes studied have been electrowinning and bioprecipitation. The samples utilised were collected from the zinc mine located in Italy and from a cooper – iron ore deposit in Slovakia. By electrochemical experiments, high metals removal, with a low energetic consumption, has been achieved: in particular, by Zn electrodeposition, it was possible to achieve 95-99% Zn removal. Culture of sulphatereducing bacteria (SRB) of genera Desulfovibrio sp. was used for the bioprecipitation tests. The precipitation kinetic of metals at the original pH of aforementioned AMD by SRB has been investigated. This method has been performed in two interconnected reactors. Achieved results indicate the 98-99% selective elimination of Cd from AMD - Italian mine, and the 98-99% selective elimination of Cu from AMD - Slovak mine by bacterially produced H2S. Both the electrowinning and bioprecipitation processes have been demonstrated the technical feasibility to decrease the heavy metals concentration. The experimental work has been carried out in the framework of the agreement of scientific cooperation between the Institute of Environmental Geology and Geoengineering of the CNR, Italy and the Institute of
Geotechnics of Slovak Academy of Sciences, Slovakia (years 2007-2009).

Full textAbstract:
Industrial pollution in Nnewi-North local Government Area, Anambra state, South Eastern Nigeria has become a major environmental concern due to unregulated discharge of industrial emissions and effluents into the environment. However, the paucity of environmental data and research from this area makes it difficult to ascertain the effect of the industrial activities on the surrounding environment. For this reason, it became imperative to assess the impact of the industrial activities on the quality of the surrounding surface and groundwater for agricultural and domestic purposes. To this end, an integration of geological, and geochemical method of analyses was adopted. The geology of the study area was determined through surface geological mapping, 22 groundwater water samples, and 3 surface water samples were collected within the study area following American Public Health Association (APHA) procedures. The sample collections were done in such a way that consider lateral and during the dry season. Atomic Absorption Spectroscopy (AAS), titrimetric and gravimetric, analytical method was used to ascertain the chemical composition of the water. The laboratory and field results were analyzed by employing several geochemical indices calculations, and inferential and summary statistics. Results from groundwater indices such as GWQI, HPI, HEI and Cd calculated with respect to WHO, 2011 and NSDWQ for both dry seasons revealed that the groundwater was contaminated, and unfit for drinking. Then from the surface water samples result of irrigation quality indices such as TH, MH, SAR, RSBC, Na% and PI calculated for dry season, indicated that the surface water is fit for irrigation for all irrigation indices expect RSBC and MH. From the statistics of PCA and T-test it was statistical proven that the source of contamination of surface and groundwater was anthropogenic (that is from industrial waste) and geogenic. Since the groundwater is contaminated, it is therefore recommended that the water should be treated before consumption.

AbstractThe government authorities in developing countries are awfully concerned with coping out the problems of the rising issues related to the disposal of solid wastes. Most of the Indian cities still dispose of solid waste unscientifically causing to severe environmental as well as public health problems. Geographic information systems (GIS) and analytic hierarchy process (AHP) have emerged as efficient tools for multiple criteria decision analysis (MCDA) in effective solutions of solid waste management. The present study focuses on the integration of GIS and AHP in identifying potential sanitary landfill areas for solid waste disposal in Durgapur city, West Bengal, India. Eleven criteria were selected viz. land elevation, slope, soil, geology, land use land cover, distance to surface water, distance to tube wells, distance to roads, distance to industrial belts, distance to sensitive places, and land cost. All the criteria were aggregated using weighted overlay analysis in GIS environment. The study identified three potential landfill areas for MSW disposal covering the areas of 13.83854, 33.80678, and 27.20085 ha, respectively, in Durgapur city. The result found that land cost value was the most significant criterion in the model with a weight of 0.25258. Followed by land cost value, sensitive places and roads were the second and third most important criteria with a weight value of 0.1409 and 0.1233, respectively.

Full textAbstract:
Se is essential to human and animal health but can be toxic in excess. An interest in its geochemistry has developed alongside a greater understanding of its function in a number of health conditions. Geology exerts a strong control on the Se status of the surface environment; low-Se rock-types (0·05–0·09 mg Se/kg) make up the majority of rocks occurring at the Earth's surface, which in turn account for the generally low levels of Se in most soils. However, there are exceptions such as associations with sulfide mineralisation and in some types of sedimentary rocks (e.g. black shales) in which contents of Se can be much higher. Baseline geochemical data now enable a comparison to be made between environmental and human Se status, although a direct link is only likely to be seen if the population is dependent on the local environment for sustenance. This situation is demonstrated with an example from the work of the British Geological Survey in the Se-deficiency belt of China. The recent fall in the daily dietary Se intake in the UK is discussed in the context of human Se status and declining use of North American wheat in bread making. Generally, US wheat has ten times more Se than UK wheat, attributed to the fact that soils from the wheat-growing belt of America are more enriched in Se to a similar order of magnitude. In agriculture effective biofortification of crops with Se-rich fertilisers must be demonstrably safe to the environment and monitored appropriately and baseline geochemical data will enable this process to be done with confidence.

Sewage Sludge (SEL) has been used in agricultural activities to improve physical and chemical properties of soils. However, this compound also contains very high levels of heavy metals and pathogenic microorganisms, which can cause serious negative effects on biota and human health. This paper aims to assess potential toxicity of latosols and chernosols amended with SEL, using Eisenia andrei earthworms. Acute toxicity and behavioral tests were performed according to ASMT (2004) and ISO (2002) procedures, respectively. Heavy metals determination was made by Atomic Absorption, and mineralogical characterization by Ray-X Difratometry. Biomass loss was evaluated considering average individual weight. Mercury, lead, zinc and cooper determination in SEL in natura and soils amended with SEL revealed values higher than that recommended by Brazilian legislation. SEL addition to the soils caused no mortality to the organisms, while SEL in natura provoked lethal effects on 100% of the earthworms. Latosol in natura demonstrated higher mortality in comparison to chernosol in natura Behavioral tests indicated that 98,3% and 96,43% of the organisms avoided SEL in natura and latosol with SEL, respectively. However, only 31% of the organisms avoided chernosol with SEL, suggesting a lower level of toxicity in comparison to latosol. Possibly the natural properties of the studied soils (fertility, organic matter content, clay mineralogy, etc.) played an important role in the avoidance behavior of the organisms. Probably expansive clays presence in chernosol stimulates ions adsorption and their concentrations decreasing in soil solution; consequently contaminants bioavailability also tends to decrease. Biomass loss results revealed that the SEL addition decreased the weight loss of the tested organisms, and biomass losses were higher for latosol than for chernosol. In conclusion, it is expected that these results can be used in human health and ecological risk assessment, as well as in sustainable reconditioning of tillable soils, facilitating decision actions in environmental control and public health programs

Ammonium perchlorate, a risk to human health, was used formerly to manufacture rocket fuel at the Naval Weapons Industrial Reserve Plant (NWIRP) McGregor, McLennon County, Texas. Perchlorate exists in several groundwater contaminant plumes, whose geometries were suspected to be influenced by transmissive bedrock structures. To identify these possible contaminant-transport pathways, a towed-array ground-penetrating radar (GPR) system was used to acquire 118 line-km of data across [Formula: see text] of the property. The shallow geology consists of bedrock limestone overlain by [Formula: see text] of clay soil. For the [Formula: see text] antennas used, the conductive clay limits depth penetration to less than [Formula: see text] and yields a [Formula: see text] wavelength, reducing lateral and vertical resolution. Nevertheless, GPR data resolved the top of bedrock in many areas. Linear discontinuities in bedrock were interpreted as weathered fracture zones, and linear areas of signal loss were attributed to deeper clay weathering along fracture zones. GPR-interpreted fractures have orientations corresponding to known lineament and fault trends, appear to control plume geometries, and tend to have higher hydraulic transmissivities. GPR results led to a more complete contaminant-transport model and were used to optimize the positions of monitoring wells needed to define the extent of contamination. This reduced the cost and time required for an environmental investigation at the site. GPR was helpful also in positioning remedial trenches across contaminated structures, resulting in plume containment at the property boundaries.

The problem in this research relates to the learning theory that rarely considered as a basis in learning in Indonesia. learning plans and syllabus structure in the national curriculum is not included learning theory point. learning theory only has been less studied in the subjects in geography education undergraduate. This makes learning theory material less explored. Learning theory is also often forgotten in educational research undergraduate and postgraduate programs. Many research did not allude to the relevance of learning theory in learning. After graduating, they less develop or linking learning theory with the teaching profession. That condition makes learning essence should be strengthened to become weak or even disappear.This research aims to describe the compatibility when applying outdoor study environment subjects with the psychological theories of intelligence and meaningful learning theory in senior high school. This research used a qualitative methodology with the type of descriptive exploitative research. Data sources are students and geography teachers. The process of collecting data uses the method of observation and interviews. Data were analyzed with the 6 Cresswell's qualitative analyzing steps. The results show that the application of outdoor study is suitable both the psychological theories of intelligence and meaningful learning. The compatibility is reflected in the learning activities, there are: before, during, and after working in the outdoor. The teacher's ability to implement the basis of psychological theories of intelligence and meaningful learning makes learning more easily understood and meaningful for students.

Full textAbstract:
Mercury bioaccumulation was investigated in four tropical fish species (Genidens genidens, Aspistor luniscutis, Haemulon steindachneri and Micropogonias furnieri) from Ribeira Bay and Guanabara Bay (Rio de Janeiro State, Brazil). The sampling of 198 and 83 specimens was performed in the Ribera and Guanabara Bays, respectively. Total mercury content in fish muscles was determined by atomic absorption coupled to the thermodesorption technique. Biometry (weight and length) of the sampled specimens was performed in order to prepare bioaccumulation curves. Average concentrations of mercury in G. genidens revealed that this species presented higher levels at the Guanabara Bay and lower at the Ribeira Bay. In the Ribeira Bay, the highest average mercury concentration was quantified in H. steindachneri, which presented average content closer to the limit established by World Health Organization (500 ng/g) for human consumption. Besides that, at the Ribeira Bay mercury accumulation speed by G. genidens and M. furnieri was more accelerated than the other species collected in this bay. Although mercury input into Ribeira Bay is not so expressive, mercury seems to be more bioavailable than at the Guanabara Bay, where bottom sediments play an important role in the metals storage. If hydrogeochemical conditions of the Guananabara Bay are modified, mercury in the sediments may become easily bioavailable. Similarly, high inputs of mercury into Ribeira Bay would be easily assimilated by biota. The bioaccumulation curves obtained in this work will help in the prediction of mercury concentration in fish muscles, just using biometric data.

Groundwater is essential to crop production in many parts of the world, and the provision of clean groundwater is dependent on healthy groundwater ecosystems. To understand better the functioning of groundwater ecosystems, it is necessary to understand how the biota responds to environmental factors, and so distinguish natural variation from human induced changes. This study compares the groundwater biota of the adjacent Gwydir and Namoi River alluvial aquifers, both in the heartland of Australia’s cotton industry, and investigates the relative importance of environmental, anthropogenic, geological, and evolutionary processes on biotic distribution. Distinct differences in biotic assemblages were recorded between catchments at a community level. However, at a functional level (e.g. microbial activity, stygofauna abundances and richness) both ecosystems were similar. The distribution of biota in both catchments was influenced by similar environmental variables (e.g. geology, carbon availability, season, and land use). Broad trends in biotic distribution were evident: stygofauna responded most strongly to geological variables (reflecting habitat) and microbes to water quality and flow. Agricultural activities influenced biota in both catchments. Although possessing different taxa, the groundwater ecosystems of the two aquifers were functionally similar and responded to similar environmental conditions.

Full textAbstract:
ABSTRACT Naturally occurring asbestos (NOA) is a global public health issue because minerals that may be classified as asbestos are a common constituent of certain types of rock and soil, found in many regions on every continent. Disturbance of these rocks and soils, especially through construction activities, can result in airborne particles, leading to inhalation and risk of disease from these known human carcinogens. The presence of NOA in the environment affects all the human activities aimed at its modification, and all engineering/geological actions in the natural environment should take it into account. In the presence of NOA, specific procedures for sampling, evaluation of environmental risk, and monitoring should be applied to minimize the risk of exposure for the workers and the general public. Unfortunately, detailed procedures have been lacking to date, and consensus is difficult to achieve because basic issues, such as the definition of asbestos itself, are still open and being debated by scientists and regulators. While the term “asbestos” has been used in older geological publications, it is not currently defined by geologists. For the past century, “asbestos” was a commercial term used to describe minerals mined for specific purposes, and the term then entered the legal lexicon for purposes of control and compensation. All these basic matters are critically illustrated in the article. Finding clear and universally accepted definitions is mandatory; otherwise, there will continue to be controversial positions that can cause regulatory and legal issues and the outcome of lawsuits to be very subjective.

Abstract Environmental geology is scientific discipline dealing with the interactions between humans and the geologic environment. Many natural hazards, which have great impact on humans and their environment, are caused by geological settings. On the other hand, human activities have great impact on the physical environment, especially in the last decades due to dramatic human population growth. Natural disasters often hit densely populated areas causing tremendous death toll and material damage. Demand for resources enhanced remarkably, as well as waste production. Exploitation of mineral resources deteriorate huge areas of land, produce enormous mine waste and pollute soil, water and air. Environmental geology is a broad discipline and only selected themes will be presented in the following subchapters: (1) floods as natural hazard, (2) water as geological resource and (3) the mining and mineral processing as types of human activities dealing with geological materials that affect the environment and human health.

Health problems arising from geological materials and processes are more common than most people believe. Geology may appear remote from human health. However, rocks are the fundamental building blocks of the Earth’s surface, full of important minerals and chemical elements. Rock weathering and alteration products not only form our soils to support our crops but provide essential elements to build biology. Drinking water travels through rocks and soils as part of the water cycle, and much of the dust and gases contained in the atmosphere are of ultimate geological origin. Without this tectonic “rock cycle” connection to atmosphere and water, there can be no life. Human evolution is also intimately bound to geology. The African rift valley unique geology and metallogenesis is fundamental to the cradle of human evolution and expansion, both physiographically and bio-geochemically. Facilitated by an amplified oscillating mosaic environments climate, biology and geology, particularly in the last 2.6Ma of the 30 Ma Cenozoic cooling and drying, hominoids were not only adapted to biological and climactic factors but also parent rock elements, including metal (loids) used to build their biological structures and functions. Numerous enzymes incorporate metal(loids) central to their catalytic functions. Over 1,200 are known to be involved in neurobiology alone, likely impacting evolution of Homo habilis to H. erectus, near doubling brain size, complexity and energy demand. Metalliferous enzyme homeostatic deregulation widely impacts health from cancer to neurological diseases. Pre-adapted to the African rift biogeochemistry mosaic, a far more skewed metalliferous anthropecen now adversely impacts metal homeostasis and our health. Concentrating on the Medical Geology of highly toxic cadmium (Cd), we explore its environmental relationship with Breast Cancer. We studied urinary Cd levels in 150 women with Breast Cancer (diagnosis age 20 to 69 years). Cd levels trend aggressive with different risk profile from later-onset disease “stage III”. Conditional logistic regression was used to calculate odds ratios and 95% confidence intervals. After correcting for differential calendar time of sample collection, statistically significant associations were observed between Cd levels and Breast Cancer risk amongst participants with localized breast cancer, Odds Ratio (OR): OR=1.35; 94% CI: 1.2- 1.8; p=0.004 and participants with regional/distal Breast Cancer: OR=1.81; 96% CI: 1.4-2.4; p=0.001. We concluded, the association of Breast Cancer risk with Cd levels did not differ between participants treated by surgery and/or radiation (p ≥ 0.05) only OR=1.34; 93% CI: 1.0-1.5 and those treated with chemotherapy OR=1.35; 94% CI: 1.0-1.6. Cd exposure probably related to the association between Cd and renal diseases, cardiovascular outcomes, cancer, especially Breast Cancer family history. Avoiding excessive metal(loid), including Cd, in all sources is advisable. These may include tattoo and or colorful cosmetics, Indian rice dietary habits, known higher in metal(loids) due to expensive local rice and smoking. We recommend women older than 40 years, particularly with family Breast Cancer history, to largely avail themselves of a plant based diet, along with adequate heavy metal ameliorating trace elements e.g. selenium, to drink anti-inflammatory herbal tea in daily diet, and non-smoking habits.

Full textAbstract:
Health care delivery in the Circumpolar North is challenged by a scarcity of culturally relevant health care services, few medical providers trained in cross-cultural care, and high costs of transportation. Community health workers (CHWs) are primarily Indigenous individuals who provide on-the-ground health care and health promotion services in their own communities. The CHWs’ scope of work varies from health education to clinical care and often focuses on upstream factors that impact the public’s health. Although often overlooked and underutilized, the CHW role is an innovative approach to promoting more sustainable and culturally relevant care within health systems. Investigating and understanding the potential ways that CHW-integrated health care systems support health and wellness could allow for a clearer understanding of how to translate this approach to other regions seeking a transition to sustainability in health and wellness. Drawing on experiences with CHWs in the Circumpolar North, this article introduces a conceptual model summarizing pathways that describe how integrating CHWs supports wellness in their communities. The proposed model includes five pathways for how CHWs could support wellness: (1) the recruitment of CHWs from within a community promotes community capacity and control; (2) the CHW role allows them to advocate to address structural and systemic inequalities that contribute to ill health, if CHWs are supported to organize their communities around wellness; (3) CHWs have the potential to support and empower community members; (4) CHWs have the potential to develop culturally relevant, feasible, and effective health promotion strategies; and (5) CHWs have the potential to build on community strengths. This model allows for CHW-integrated health care systems to be critically examined to both test and refine this proposed model, and support and empower community health workers as a transition to a more sustainable health care delivery system that reduces inequities and promotes health.
