In this paper, the residues of organochlorine pesticides including HCH and DDT in soils of some rural area in Nanchong City of Sichuan Province were monitored continuously for two years during 2010 - 2011. The results showed that nearly none HCHs in soil were detected in 2011. The detectable rates of DDTs in two years were 100% ; the main residue of OCPs was p, p ' -DDE, accounting for 75% of the total residues ; the residue levels in the lands for different usage were ranked as vegetable land 〉 polluted area 〉 basic farmland 〉 residential area; the HCHs contents in all soil samples reached the Grade I ( 〈0.05 mg/kg ) of "Soil Environmental Quality Standard (GB15168 - 1995) of China, the content of DDTs in all soil samples reached the Grade II ( 〈0. 50 mg/kg), belonging to light pollution.关键词
