Comments

A cholinesterase inhibitor; [Hawley] A mild skin and eye irritant; In an exposure of 120 vineyard workers, symptoms included dizziness, weakness, headache, blurred vision, and tightness in the chest; Most plasma and red cell values were depressed more than 60%. All fully recovered, although 85 received medical attention and three were hospitalized; [HSDB] Some evidence of reproductive effects in feeding study with hamsters; [RTECS] No adverse gross or histopathological observations in three generation oral study with rats; No teratogenic effects observed in two studies with rabbits and one with macaques; No evidence of mutagenicity; No clinical observations of neurotoxicity in study with birds; Mildly irritating to skin and eyes of rabbits; Effects in high-dose feeding studies with rodents include cholinesterase inhibition and some evidence of liver necrosis; No significant effects observed in gross, histopathological, or tumor frequency in long term feeding studies with rats; [INCHEM JMPR]
