(22) suggested that the formation of DEA from alachlor in rats and monkeys is dependent upon the conjugation of alachlor to glutathione, consequent enterohepatic circulation of this reduced glutathione (GSH) conjugate, conversion of the GSH conjugate to the secondary methylsulfide, and amide hydrolysis of the secondary methylsulfide to DEA (22).
