| Abstract: |
| To study the residue characters of organochlorine pesticide（OCPs） in soil and shallow groundwater of Xiaodian sewage irrigation area, Taiyuan city, three profile soils and sixteen shallow groundwater samples were collected to analyze the content of OCPs detected by GC-ECD.The results showed that HCHs and DDTs predominate in soil-groundwater systems. The concentration of HCHs in the soil ranged from 0.25 to 9.21 ng·g-1, and 0.14 to 30.4 ng·g-1 for DDTs；The content of HCHs and DDTs in the shallow groundwater ranged from 0.30 to 51.23 ng·L-1,1.41 to 32.78 ng·L-1, respectively. Various OCPs components presented different migration in soil under the impact of wastewater irrigation. HCHs migrated faster than DDTs. p，p′-DDE was main DDTs in the soil samples while β-HCH of HCHs present the highest content in groundwater. |
