Heavy Metals Toxicity and the Environment

Heavy Metals Toxicity and the Environment

+

Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological appliions have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment.
