采用气相色谱法定量测定了桑沟湾海域2009年4月-2009年12月的经济贝类中有机氯农药和多氯联苯的残留量。结果显示:该海域贝类中 HCHs 为 N.D.~2.04×10-9,均值为0.30×10-9; DDTs 为(0.13~3.36)×10-9,均值为0.97×10-9;PCBs为(0.01~3.20)×10-9,均值为0.59×10-9,有机氯物质含量均低于相关国家标准值,符合食用安全要求。经济贝类中的有机氯农药的组分特征为HCHs中b-HCH占优势, DDTs中p, p′-DDT占相对优势; PCBs中多为5~7个氯原子。与北海等6个海域相比,桑沟湾海域经济贝类有机氯污染物中, HCHs、DDTs和PCBs的残留量都处于中等水平。

To analyze and evaluate the residue levels and distribution of organochlorinated pesticides (OCPs) and polychlorinated biphenyls (PCBs) pollutants in Sanggou Bay, the concentrations of hexachlorocyclohexane (HCHs), dichlorodiphenyltrichloroethane (DDTs) and PCBs in shellfish collected from May to December 2009 in study area were detected by gas chromatography (GC). The results showed that the shellfish was polluted by HCHs, DDTs and PCBs at different levels, but their contents were lower than the national standard value, in line with food safety re-quirements. The concentration range of HCHs was N.D.~2.04×10-9 (wet weight) and average was 0.30×10-9 . The concentration range of DDTs was (0.13~3.36)×10-9 (wet weight) and average was 0.97×10-9. The concentration range of PCBs was (0.01~3.20)×10-9 (wet weight) and average was 0.59×10-9. b-HCH occupied the main part of HCHs and p,p¢-DDT occupied the main part of DDTs, while PCBs with 5~7 chlorine occupied the main part of PCBs. Compared with the other six coastal areas, the concentration of OCPs and PCBs was at the middle level.
