Land disposal of poultry litter is an environmental concern often associated to excess phosphorus (P) in soils and potential water pollution in regions with intense poultry production. Although poultry litter can be moved off the farm and traded as fertilizer, its transportation becomes less economical with increasing distances from the farm. Thus, new litter management alternatives are needed ...

Millions of barrels of crude oil gushed freely from these wells, creating oil lakes in low-lying areas of the desert. Lakes were formed at more than 500 different locations, covering a total area initially estimated at 49 km. While the Kuwait Oil Company (KOC) has recovered 22.5 million barrels of the spilled crude; the remaining amount, is considered unrecoverable by standard methods. An estim...

Soil is a complex physical and biological system that provides support, water, nutrients and oxygen to the plants. Apart from these, it acts as a connecting link between inorganic, organic and living components of the ecosystem. In recent years, presence of xenobiotics, alterations in the natural soil environment, application of pesticides/inorganic fertilizers, percolation of contaminated surf...

In order to reveal the influence of the metals of soil-water interface in a manganese mine (Xiangtan, China), on local water environment, there are six kinds of metals (Mn, Ni, Cu, Zn, Cd, and Pb) characterized by measuring their concentration, correlation, source, and special distribution using principal component analysis, single factor, and Nemero comprehensive pollution index. The results s...

In the present study the effect of sewage water and canal water irrigation were compared by their physicochemical properties and heavy metals concentration in soil. The mean values of different physico-chemical parameters and heavy metals were : Bulk density (gm/cm) 1.26, Water holding capacity(%)-53.60, Temperature(oC)-16.33, Electrical conductivity (dsm-1)0.122, pH-7.5, Organic carbon (%)-1.9...

water and soil pollution by human pathogenic bacteria draw attention of many researchers. duration of bacterial survival for reach to the soil and water resources is very important. current study focused on the effects of caco3 and caso4 compounds on escherichia coli survival. using caco3, caso4 compounds and fine sand particles (
