One of the most common kidney problems nephrotoxicity has been traced to exposures to drugs and toxic chemical substances. The disorder eventually causes kidney damage and disturbs the body functions and elimination of urine and wastes. Reports have indicated that prolonged periods of exposure to metals causes neurotoxicity among workers. Also cadmium other environmental heavy metals and the organometallic compounds used as therapeutic agents anticancer drugs cyclosporin analgesic abuse and antibiotics have been implicated in kidney disorder diseases. The kidney is the filtration mechanism for the blood. As is well known the kidney has to perform three major functions to maintain normal health.

However prolonged exposure to chemical substances causes adverse health effects and damage of the renal system in animals and humans a health disorder termed nephrotoxicity. This disorder has been found among workers and members of the public exposed to toxic chemicals and because of improper medication. The chemical substances that cause damage to the renal system are called nephrotoxins.
