Abstract:

Soil is an essential ecosystem, delivering valuable services such as the provision of food, energy and raw materials, carbon sequestration, water purification and infiltration, nutrient regulation, pest control and recreation. Therefore, soil is crucial for fighting climate change, protecting human health, safeguarding biodiversity and ecosystems and ensuring food security. Pollution of the soil by organic and inorganic substances is, therefore, detrimental to ecosystem services and/or human health. Heavy metals at harmful concentrations are highly detrimental, and here, mining activities are

Abstract:

In this paper a stepwise adsorption purification bed was introduced to be used for overflow wastewater treatment. According to the principle of natural purification of soil and paddy fields on sewage, the stepwise adsorption purification bed imitated the self-purification function of natural materials, such as defoliation，rotten wood, charcoal and the stone were processed as filler. The removal rate of the parameters, such as COD, NH3-N and TP was invested to show the treatment effect of this system. The result showed that the system had a high removal rate of the contamination in the sewage.

Abstract:

On-site wastewater treatment and dispersal systems (OWTS) are used in non-sewered populated areas in Australia to treat and dispose of household wastewater. The most common OWTS in Australia is the septic tank–soil absorption system (SAS)—which relies on the soil to treat and disperse effluent. The mechanisms governing purification and hydraulic performance of a SAS are complex and have been shown to be highly influenced by the biological zone (biomat) which develops on the soil surface within the trench or bed. Studies suggest that removal mechanisms in the biomat zone, primarily adsorption a

Abstract:

The unsaturated zone is recently getting special attention because of its purification efficiency on discharges of septic tanks, leaking sewers, and seepage of agricultural lands. Since knowledge of quantitative effects and removal processes is poor, investigations are conducted by the use of lysime-ters and a full-scale soil disposal system. Results on variation of seepage water ingredients and mass balances are shown. These and further results give the possibility of upgrading soil disposal systems, in order to minimize pollution of soil and groundwater.

Abstract:

The data on the gross harvest of tubers in the Russian Federation are given: approximately 71% of potatoes are produced by the population, 17.4% by agricultural enterprises and 11.5% by farms. It is noted that in the industrial production of potatoes, negative impacts on the soil are associated with crushing and removal of the fertile soil layer, which arise in the process of extracting root crops by the digging and separating working bodies of the harvesting machines. It is proposed to use ultrasonic action on root crops for cleaning them from soil impurities. It was determined that in order

Abstract:

In leather industries and tanneries, large amount of wastes has been disposed; which polluting water, soil, and atmosphere and causing serious human health problems. In particular, chemical dehairing process of leather industries produces fair amount of toxic wastes. It is, thus, urgently needed to use alternative processes free from pollution. As more than 90% of keratin is contained in feather, it is desirable to develop bioremediation process using keratinolytic microorganisms. In the present investigation, therefore, we first identified Bacillus cereus and Pseudomonas sp. to be able to pro

Abstract:

Growing NH4+ content of groundwater results in increasing exchangeable and fixed ammonium ion content of the soil. NH4+ bond in the soil may go again into solution parallel with the dilution of the soil solution but at a slower rate than fixing. This process influences significantly the NH4+ content of the soil. In settlements with no sewerage system the high NH4+ content of sewage flowing out of uninsulated septic tanks may increase the fixed NH4-N content of the soil that could have a significant effect on the quality of groundwater even after the potential disappearance of pollution sources

Abstract:

Plastic pollution is one of the biggest environmental problems facing the world. In recent years, microplastics, polymer particles from 1 µm to 5 mm, have been getting much attention. The presence of microplastics has already been confirmed in aquatic and marine ecosystems, soil, atmosphere, biota, and others. The organic output from mechanical–biological treatment (MBT) plants was added to the list of microplastics sources only recently. However, according to preliminary estimates, it may be the second-largest source of microplastics. This article presents an overview of already published inv

Abstract:

The intensification of pig production is considered a risky activity for the environment when the generated pig slurry is not adequately treated. In addition, intensive agriculture practices where pig slurry is applied to the cropland could cause nitrate leaching, salinization, and soil pollution (heavy metals and pathogens), thus the development of an eco-friendly system for pig slurry treatment is essential to avoid undesirable environmental impacts. The main objective of this study was to assess the efficiency of an integrated purification system (IPS) for treating pig slurry. The system in

Abstract:

Landfills of municipal solid waste (MSW) have a negative impact on the environment and people: air, soil, surface water and groundwater are polluted. During the storage of MSW in the body of the landfill natural anaerobic decomposition of organic waste takes place under conditions of oxygen lack, high temperature and humidity. One product of this process is landfill gas - a mixture of methane and carbon dioxide with small amounts of impurities (nitrogen, silicon, sulfur, hydrogen sulfide). Tens and hundreds of different organic compounds are also included as a compound of landfill gas. The com

Abstract:

Biofilms are the result of adhesion and growth of microorganisms at interfaces. They consist mainly of water (70-95 % wet weight), held by the highly hydrated extracellular polymers (EPS, 70-95 % dry weight) in which the microorganisms are embedded. Adhering cells differ from their suspended counterparts in both activity and resistance to toxic substances. The cells are immobilized next to each other and form well organized consortia, capable of performing sequential degradation processes. Biofilms are ubiquitous and the majority of microorganisms on earth is living in biofilms. The particular

The “ecological ditch” (eco-ditch) is an effective measure used to alleviate agricultural non-point-source pollution. However, information is lacking about the continuous transport characteristics of internal and external nitrogen and phosphorus in the interstitial water of the bottom mud of these ditches and overlying water under dynamic continuous inflow conditions. Understanding of the effect of matrix dams and microbial communities inside eco-ditches on the continuous transport characteristics of the N and P therein needs to be improved.
