Abstract
The draft Toxicological Review of Urea provides scientific support and rationale for the hazard and dose-response assessment pertaining to chronic exposure to Urea. Urea, also known as carbamide, is an endogenous product of protein and amino acid catabolism. It can also be produced synthetically by combining ammonia, carbon monoxide, and sulfur in methanol. Urea is utilized in diesel selective catalyst reduction, in fertilizers and animal feed, plastics, flame-proofing agents, adhesives, flavoring agents and consumer goods such as liquid soaps, detergents and household cleaning products.
