| 摘 要： | 于1994年6月，采用高分子多孔聚合树脂对武汉东湖水进行富集采样，样品经净化后利用毛细管柱色谱进行多氯联苯（PCBs）总量及同类物（congeners）的分离测定。结果表明，东湖水样中PCBs总含量为2．7ng／L，检出的20多个PCBs同类物其含量分别在0．002－1．12ng／L范围内。其同类物中低氯取代的PCBs相对含量明显高于工业用商品PCBs中的相应含量。

| Abstract: | Water samples were collected from Donghu Lake in June 1994 and preconcentrated using XAD-2 resin. The polychlorinated biphenyls(PCBs) fraction of the sample was analyzed by high resolution GC. The concentration of PCBs in Donghu Lake was 2.7ng / L and the concentrations of individual congeners of PCBs ranged between 0.002 and 1.12ng / L The pereentages of congeners with a relatively small number of substituted chlorine atoms in the sample were apparently higher than those in commereial PCBs. |
