Calculate volatile organic compound emissions from agricultural applications of nonfumigant pesticides. Although dichlorvos doesn’t accumulate in the environment nor in the bodies of living organisms, it remains a substance toxic to several animals. Once in the body, permethrin decomposes to the liver to safe metabolites. Hence, it can be concluded that Cypermethrin in do have adverse toxic effect on the humans and animals, though the toxic level varies with the nature and extent. While the LC 50 for inhibiting mammalian brain acetylcholinesterase is similar between dichlorvos and paraoxon (i.e., the active metabolite of parathion), the acute LD 50 values for these agents are considerably different, due in part to the more rapid metabolism and elimination of dichlorvos.
