title: Study of the degradation products of bromopropylate, chlordimeform, coumaphos, cymiazole, flumethrin and tau-fluvalinate in aqueous media.
abstract: Degradation processes of bromopropylate, coumaphos, chlordimeform, cymiazole, flumethrin and fluvalinate in aqueous media have been studied by HPLC. Cymiazole is stable at any tested pH (1-11), while bromopropylate, flumethrin and coumaphos are unstable at basic pH and chlordimeform and fluvalinate in neutral and basic media. The main degradation products have been identified by GC-MS. The reaction rate constants and half-lives were calculated and the effect of co-solvents on the rate and product profile was studied.
