Bioaccumulation of some heavy metals: An overview

Abstract

The use of heavy metals has increased with rapid population and urbanization which
in turn has both positive and negative impacts. As some of them are essential
elements to living systems, many of them are being used in the manufacturing of
products thereby fulfilling the physical demands of many products in our lives in a
way heavy metals are good for us while their accumulation into the soil affects soil
ecosystem, plants and ultimately to the human body has adverse effects in the human
body with different concentration. As it has an adverse effect on the long run as well
as in short durations, it becomes an emerging field to investigate the sources of heavy
metal, its pathways through which it could enter the biological system including both
the environment and the human body and its effect on the human body.
