To better understand the fate of dichlorodiphenyltrichloroethane (DDT) in the atmosphere, probing the oxidation mechanism of DDT is of great importance. The results showed that the degradation of DDT yields oxygenated DDT and nitrated DDT including phenolic compounds, dialdehyde, epoxides and nitrooxy-DDT. The rate constant for the reactions of DDT with OH and NO3 radicals are 1.16 x 10(-11) cm(3) molecule(-1) s(-1) and 2.19 x 10(-14) cm(3) molecule(-1) s(-1), respectively in the temperature of 298 K. The lifetime of DDT determined by the reactions with OH and NO3 radicals is 8.1 h.
