A review on sources of heavy metal pollution ind its impacts on environment

Atia Arzoo and Kunja Bihari Satapathy

Human activities such as industrial production, mining, agriculture and transportation, release high amounts of heavy metals into surface and ground water, soils and ultimately to the biosphere. Some of heavy metals at very low concentration are essential for plants and animals but at higher concentration all heavy metals are toxic to the environment. This paper briefly explains about the impacts of heavy metals on environment. It is evident from the several research reports that judicious use and presence of heavy metals have toxic effects on plants, animals and other living organisms and affects the same after certain limits. Therefore, it is well needed to intensify the research programmes for better understanding of heavy metal toxicity on environment and its remediation.
