Almost thirty chemical elements are persistently found in living organisms, taking part in vital biochemical and physiological functions, and recognized as essential elements for life. Those required in higher concentrations per day, form the main electrolytes and take part in the maintenance of the homeostasis. Those required in few micrograms to a few milligrams per day are Essential trace elements also participate in numerous biochemical vital processes necessary to maintain good health. Majority of the known metals and metalloids are very toxic to living organisms and even those considered as essential, can be toxic if present in excess. Metal ions present in the solid phase available under certain biological and physico-chemical conditions such as, exudation of special chelators, desorption, redox and pH changes, etc. The dietary contribution for toxic metal intake has been extensively studied
