Abstract
This paper reports on the stability of 6 organophosphorous insecticide s in ethanol-water at pH 2.0, 7.5 and 8.5. The kinetics of insecticide degradation and the corresponding parameters were calculated from the data obtained by analyses of the residual parental compounds. Pestici de degradation was found to proceed by 2 distinct mechanisms.
