Présentation
Heavy metal is a member of an ill-defined subset of chemical elements that exhibit metallic properties. Many different definitions of the term heavy metal have been proposed, based on either density, atomic number, atomic weight, chemical properties or toxicity. The term heavy metal refers to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations. Examples of heavy metals include Mercury (Hg), Cadmium (Cd), Arsenic (As), Chromium (Cr), Thallium (Tl), and Lead (Pb) “Our focus element in this study”.
