Abstract
Degradation processes of bromopropylate, coumaphos, chlordimeform, cymiazol e, flumethrin and fluvalinate in aqueous media have been studied by HPLC. C ymiazole is stable at any tested pH (1-11), while bromopropylate, flumethri n and coumaphos are unstable at basic pH and chlordimeform and fluvalinate in neutral and basic media. The main degradation products have been identif ied by GC-MS. The reaction rate constants and half-lives were calculated an d the effect of co-solvents on the rate and product profile was studied.
