In the recent past, household hazardous waste has become an issue to more and more communities. In an effort to control the pollution generated within a household, various methods have been set forth in col­ lecting and disposing of these wastes. Unfortunately, all too often the hazardous waste collection days are poorly attended, and the costs become prohibitive when measured against the amoun...

according to the reports, industrial livestock activities have most pernicious and harmful impacts on water resources quality. livestock activities include cattle breeding, animals feeding, cleaning animals resting sites, the storage of livestock manure and even abandoned places for livestock keeping impose large negative effects on water quality. such impacts stems from high density or livesto...

In recent years, optimal use of fossil fuels, reduction of environmental pollution and exploitation of renewable energy is one of the most important issues in the policies of different countries, and as you know, Iranchr('39')s electricity industry is dependent on fossil fuel consumption strongly, which causes environmental pollution. The aim of this study is to obtain the optimal combination o...

existence of heavy minerals in waters in some regions causes serious environmental pollution and affects the soil and water resources quality. soil and waters sensitive to pollutants were investigated in this research, based on the degree of sensitivity of their parameters. the samples obtained from industrial and agricultural areas for identifying water tables at higher risk and display region...

Numerous studies have shown a positive association between daily mortality and particulate air pollution, even at concentrations below regulatory limits. These findings have motivated interest in the shape of the exposure-response relation. The authors have developed flexible modeling strategies for time-series data that include spline and threshold exposure-response models; they apply these mo...
