Heavy metals can be emitted into the environment by both natural and anthropogenic causes. The anthropogenic sources of emission are the various industrial point sources including former and present mining sites, foundries and smelters, combustion by products and traffics. Through rivers and streams metals are transported as either dissolved species in water or an integral part of suspended sediments. Human health is under constant risk of deterioration due to increasing chronic exposure of such metals that adversely affect the quality of life of people. The deterioration of human heath due to exposure to heavy metals has become a major issue of concern worldwide. If one is exposed to cadmium a number of factors will determine whether or not a person will be affected. These factors are age, sex, diet, family; life style and state of health also tend to contribute to determine extent of exposure. The objective of this paper is to review available information on possible toxicities of cadmium on human health.
