presence of arsenic, a heavy metal, in soil and water resources originating from geological formations of qorveh plain, which is considered as the main agricultural zone of kurdistan province in western iran, has put the agricultural products of this region at risk of pollution. since arsenate, as the most abundance form of arsenic in soil environment, competes against phosphate anion; applicat...

abstract herbicides are the main sources of soil and water pollution in paddy fields. herbicides mobility to the surface and ground water is a major concern for human health and the environment. it is, therefore, necessary to investigate their fate and their interactions in natural ecosystems. to meet this purpose, field experiments were conducted to measure kinetic of thiobencarb dissipation i...

We quantitatively investigated the eighth century heavy metal pollution in Heijo-kyo (Ancient Nara), the first large, international city of Japan. In this metropolis, mercury, copper, and lead levels in soil were increased by urban activity and by the construction of the Great Buddha statue, Nara Daibutsu. Mercury and copper pollution associated with the construction of the statue was particula...

Background Environmental health professionals (EHPs) have always played a critical role in protecting the public’s health by preventing outbreaks, responding to environmental emergencies, and enforcing public health standards. Tradi­ tionally, this role has not focused on improv­ ing the built environment, which is the physi­ cal environment where people live, work, and play. The design of the ...

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...

Pharmaceuticals used in livestock production may be present in manure and slurry as the parent compound and/or metabolites. The environment may therefore be exposed to these substances due to the application of organic fertilisers to agricultural land or deposition by grazing livestock. For other groups of substances that are applied to land (e.g. pesticides), preferential flow in clay soils ha...

Soil contamination due to the compounds of chlorophenols is very difficult to treat. Among the chlorophenols, pentachlorophenol (PCP) is quite persistent in the environment which causes serious pollution problem to the surface and subsurface environment (Berta et al., 2007). PCP, an important class of compounds, is used in many industrial applications, and is found in the effluent and soil asso...
