Abstract：The atmospheric organochlorine pesticides (OCPs) in the Shijingshan District of Beijing was analyzed by gas chromatography (GC). It was found that the concentration of HCHs, p,p’- DDT, p,p￠-DDE, p,p￠-DDD, o,p￠-DDT, heptachlor, chlordane was 4344.4, 1000.2, 778.0, 213.4, 1319.3, 645.7 and 376.6 pg/m3 in the gas phase and was 37.3, 5.3, 0, 0.7, 15.8, 1.6, 0.6 pg/m3 in the particle phase, respectively. The OCPs were mostly existed in the gas phase. HCHs and DDTs were the most abundant compounds in the atmosphere which totally accounted for 87.2% in gas phase and 90.9% in the particle phase. The concentrations ratio of α-HCH/γ-HCH and p,p￠-DDE/p,p￠-DDT were <1.5 and <1.0, respectively, indicating some new input of γ-HCH and DDT in the Beijing area. Most of the atmospheric OCPs in Beijing air were from the historical usage. The application of dicofol is a possible new source of DDT in the environment.
