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.

Interaction of Lead with Calcium, Iron, and Zinc in the

31/08/2017· Interaction between toxic and essential elements is of particular interest, because the deficiency of essential element can dramatically increase the absorption rate of toxic metals inside the body. This study was conducted to evaluate the possible correlation of lead (Pb) with calcium (Ca), iron (Fe), and zinc (Zn) in biological samples (whole blood and scalp hair) of malnourished children (MNC).

Chapter 6.4 Chromium

Chromium (Cr) is a grey, hard metal most commonly found in the trivalent state in nature. Hexavalent (chromium(VI)) compounds are also found in small quantities. Chromite (FeOCr2O3) is the only ore containing a significant amount of chromium. The ore has not been found in the pure form; its highest grade contains about 55% chromic oxide (1).
