| 摘 要： | 采用GC／MS法对哈尔滨市18个表层土壤及1个深层土壤中PCBs的浓度进行了测定，并讨论了PCBs在土壤中的分布特征及同族体的组成情况。结果表明，该市表层土壤中∑PCBs浓度分布在0．025-1．795ng／g之间，平均值为0．545ng／g，深层土壤中未能检测到目标物，土样中共有18种同系物有不同程度的检出，主要以五氡联苯为主，其中工业区的土壤样品中∑PCBs含量最高。

| Abstract: | The concentration levels of PCBs in eighteen top-soil samples and one deep soil sample collected in the Harbin city were analyzed by GC-MS.The spatial distribution of PCB congeners and composition of PCB homologues were also discussed.The results showed that values of PCBs in the top-soil samples were in a range of 0.025～1.795ng/g,with an average value of 0.545ng/g.And no PCB congeners were detected in the deep soil sample.Eighteen PCB congeners were detected at different residue level,among which the Penta-chlorinated biphenyls are abundant in all samples.PCB concentrations are higher in industrialized area than those at other sites. |
