1 Answer

Answer :

(1) Cadmium Explanation: Cadmium (Cd), a by-product of zinc production, is one of the most toxic elements to which man can be exposed at work or in the environment. Once absorbed, Cd is efficiently retained in the human body, in which it accumulates throughout life. Cd is primarily toxic to the kidney, especially to the proximal tubular cells, the main site of accumulation. Cadmium accwnulates in the kidneys and may sometimes cause kidney failure when it is in excess.
