GEOLOGICAL AND BIOLOGICAL REDISTRIBUTION OF HEAVY METALS THROUGH POLLUTION AND ITS ADVERSE EFFECT ON FOOD SAFETY

ABSTRACT/DESCRIPTION


Wastes are the major source of soil pollution originates from mining, chemical, metal processing industries and other allied industries. These wastes include varieties of chemicals like heavy metals, phenolic organic, non metals etc. Heavy metals are the intrinsic component of the environment with essential and non essential both types. Soils polluted with heavy metals have become common due to increase in geologic and anthropogenic activities. It is the unplanned disposal of municipal waste, mining, use of extensive pesticide, insecticide, fungicides and other agrochemicals uses were significant causes of environment pollution and causes of most concern. Heavy metals such as Cadmium, Copper, Lead, Chromium, Manganese and iron are major environmental pollutants particularly in areas with high anthropogenic pressure. Heavy Metals accumulation in soils is o concern in agricultural production due to the adverse effects on food safety, marketability and crop growth due to phytotoxicity and environmental health of soil organisms. The influence caused by the geological and biological redistribution of heavy metals through pollution of the air, water and soil were briefly discussed in this work.
