The effect of concentration (0.01; 0.1; 1 ppm), polarity of solvent (hexane and 2-propanol), dose rate of gamma-irradiation (0.026; 0.042; 0.14 kGy/min) on a radiation degradation degree of organochlorinated pesticides (OCP) is discussed in this article. The conditions of maximal degradation of model solutions of OCP under gamma-irradiation are determines, based on the results obtained.
The results of formation of stable products of organochlorinated pesticides (OCP) under gamma-irradiation (dose 10 kGy, dose rate 0.026, 0.14 kGy/min) are discussed in the article. The model solutions of alpha-,gamma-hexachlorocyclohexane (alpha-,gamma-HCH), p,p-dichlorodiphenyl-trichloroethane (p,p-DDT) and p,p-dichlorophenyl-dichloroethylene (DDE), with initial concentrations of 1.0-0.1 ppm, were exposed to gamma-radiation. Among the products of OCP radiolysis such compounds as DDE, 2,2-di(chlorophenyl)-1-chloroethylene, dichlorophenyl-dichloroethane and various isomers of HCH were found. It was shown that taking in account the whole data on the formed metabolites the toxicological characteristics of pesticide solutions cannot be improved by exposure to gamma-radiation.
