Source control by on-site retention and infiltration of stormwater is a sustainable and proven alternative to classical drainage methods. Unfortunately, sedimentary particles and pollutants from drained surfaces cause clogging and endanger soil and groundwater during long-term operation of infiltration devices. German water authorities recommend the use of infiltration devices, such as swales o...
Composting (aerobic treatment of organic wastes) and digestion (anaerobic treatment of organicwastes combined with biogas production) are important waste management strategies with increasingsignificance in the European Union and Switzerland. Most of the compost produced is applied toagricultural soils, which hereby recycles nutrients and influences soil properties beneficially. How...
Origin and impact of heavy metal and radionuclide pollution Pollution of soil by heavy metals arises from a number of sources, including emissions from motor vehicle exhausts and from manufacturing industry, sewage sludge application, and acid mine drainage. Heavy metals such as zinc, cadmium and lead are toxic and may affect man directly through ingestion after passing through the food chain [...
The effluent generated from a thermal power plant waste is a mixture of several chemicals and to identify the effect of these chemicals on soil, a case study on naturally contaminated sites at Al-Musayyib region, Hilla city in Iraq has been carried out. Soil and water samples were collected from the sites and analyzed to identify the pollutants and their effect on soil characteristics. Laborato...
A health risk assessment of long-term emissions of carcinogenic and non-carcinogenic air pollutants has been carried out for the municipal solid waste incinerator (MSWI) of the city of Taranto, Italy. Ground level air concentrations and soil deposition of carcinogenic (Polychlorinated Dibenzo-p-Dioxins/Furans and Cd) and non-carcinogenic (Pb and Hg) pollutants have been estimated using a well d...
Nowadays study of the industrial pollutions has become a controversial issue to reduce the risks of them in all of the world. Studding of air, water, and soil pollutions as separately may cause neglect from address to a comprehensive look in industrial pollution issue. In addition, without the exact information about quantity and quality of pollution sources, reduce or eliminate industrial poll...
Contamination of soil, sediments and groundwater by organic pollutants is a current problem that threatens both human and environmental health. The use of microorganisms to remediate pollution (bioremediation) is a viable option for site remediation. However, limited knowledge exists concerning the key microorganisms involved in the degradation of many pollutants. In this study, specific aspect...
Plants are good environmental sensors of the soil conditions in which they are growing. They also respond directly to the state of air. The tops of plants are collectors of air pollutants, and their chemical composition may be a good indicator for contaminated-areas when it is assessed against background values obtained for unpolluted vegetation. Both, aquatic and terrestrial plants are known t...
Passive sampling devices have been used since the 1970s to measure time-weighted average (TWA) or equilibrium concentrations of pollutants in various environmental matrices (e.g. air, soils and sediments and water). In recent years the popularity of using such samplers has increased and the technology in now well established for the measurement of atmospheric pollutants. This sector has a long ...
Environmental and economic problems in water bodies can result from the lack of understanding of these processes. For example, sediment moving through a watershed transports nutrients and pollutants that can damage aquatic habitat and reduce soil productivity in agricultural areas. In addition, sediment movement and deposition in streams can increase the cost to maintain navigation and interfer...
