Assessment of Heavy Metal Contamination in Soil: A Review

Abstract: Metal contamination in soil is a major problem growing rapidly now-a-days due to industrialization and human activities such as mining, smelting and electroplating. Metals above their permissible limit are dangerous due to high toxicity as they affect human and animal health. The high amount of these metals in soil is unacceptable for the cultivation of crops due to the risk of bioaccumulation and biomagnifications in the food chain. Thus, indirectly affect human health. Furthermore, decreased soil microorganism activity is also due to the presence of high amount of metal in soil as a result soil quality decreased. Thus, presence of high amount of metal in soil is one of the major environmental factors which influences many aspects of human life. Therefore, in light of above this study is an attempt to assessing the heavy metaleffects in soiland its consequences.
