The virtual elimination of the principal point sources of human bacterial pollution through advanced treatment systems has not produced 100% compliance with microbial standards at all UK bathing water locations where they have been installed. This is partly explained by the existence of diffuse bacterial pollution derived from agricultural activities within catchments draining to the bathing zo...

It has been more than half a century that plant geneticists and breeders have been trying to assemble a combinationof genes in crop plants, in order to make them as suitable and productive as possible. Plant transformation technology incrop plants was first undertakenin the 1980s based on the ability of foreign gene integration into host plant genome andregeneration of transformed plant cells i...

Polychlorinated Biphenyls (PCBs) have been widely used to flame-retard products common in homes and theworkplace, and subsequently. Polychlorinated biphenyls (PCBs) typify a class of highly toxic, stable aromaticpollutants. PCBs are recently being scrutinized for potential environment damage in groundwater and in theatmosphere. The elimination of chemical pollutants from a contaminated environm...

INTRODUCTION Winter air pollution in Ulaanbaatar, Mongolia is among the worst in the world. The health impacts of policy decisions affecting air pollution exposures in Ulaanbaatar were modeled and evaluated under business as usual and two more-strict alternative emissions pathways through 2024. Previous studies have relied on either outdoor or indoor concentrations to assesses the health risks ...

one of the main problems in the quality control of rivers is the high control cost imposed upon pollutant units. the cooperative policy approach in the treatment process between two or more pollutant units is a new and economic perspective in the environmental management of catchment basins. origins of large amounts pollutants which require a high cost to control pollution are trying to start p...

petroleum hydrocarbons are important energy resources used by industry and in our daily life, whose production contributes highly to environmental pollution. to control such risk, bioremediation constitutes an environmentally friendly alternative technology that has been established and applied. it constitutes the primary mechanism for the elimination of hydrocarbons from contaminated sites by ...

the sources of groundwater pollution such as, industrial effluents, sewage and extensive farming have lead to agrochemical pollution. mathematical modeling helps to analyze the existing situation, allows forecasting, and to evaluate the effects of changes in the surrounding water quality. the present research has been focused mainly towards understanding the various processes affecting the tran...

In this study, ZnO/TiO2 and ZnO/Nb2O5 photocatalysts were evaluated in the river pollution remediation wastewater treatment from textile factories, thus, target pollutants selected for study enteropathogenic bacteria commercial dyes. The mixed oxide systems extensively analyzed order to explore their physicochemical properties. From analysis, it was found that coupling of two oxides did not mod...

In the process of sustainable development regions, negative consequences arise in form (1) depletion natural and energy resources, (2) reduction biological diversity, (3) violation stability ecosystems, (4) pollution environmental objects, including atmospheric air. The constant prolonged chronic aerogenic impact aromatic hydrocarbons on human body can make a significant contribution to formati...

Traditional tanning practices often result in harmful waste products that pose significant environmental risks, including water pollution, non-biodegradable solids, hazardous emissions, and unpleasant odors. However, this study introduces a simple effective alternative method for industrial-scale vegetable tanning, with the goal of minimizing pollution. This innovative eliminates use common sal...
