| 中文摘要: |
| 为了研究有机氯农药（OCPs）在污灌区土壤和浅层地下水中的残留特征，运用气相色谱电子捕获检测器（GC-ECD）对太原市小店污灌区3个钻孔不同层位土样和16个浅层地下水样中的OCPs进行检测。结果表明：六六六（HCHs）和滴滴涕（DDTs）普遍存在于污灌区土壤和地下水中，土壤中HCHs含量范围为0.25～9.21 ng·g-1， DDTs残留范围为0.14～30.4 ng·g-1；浅层地下水中，HCHs含量范围为0.30～51.23 ng·L-1，DDTs残留范围为1.41～32.78 ng·L-1；污灌对OCPs不同组分在土壤中的垂直迁移影响不同，相对于DDTs，HCHs更容易向深层土壤中迁移；土壤中p，p′-DDE含量最高，地下水中β-HCH平均含量最高。 |

| 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. |
