摘　　要：对某电子垃圾拆解区及周边土壤和河流沉积物进行了采样检测,分析了土壤和沉积物中多氯萘的污染程度。结果表明,所有土壤和沉积物样品中均检出了PCNs,土壤样品中ΣPCNs的浓度范围为95.94～3 061.26 ng/kg;沉积物中为56.23～1 981.51 ng/kg。与国内外其它研究相比,研究区域内土壤中PCNs处于中高水平;沉积物中PCNs处于中低水平。The soil and sediment samples from an electronic waste recycling area were sampled to analyze the degree of pollution of polychlorinated naphthalenes（PCNs）. The PCNs were detected in all soil and sediment samples,with total concentration of PCNs（∑PCNs）in soil samples in the range of 95.94～3 061.26 ng/kg and 56.23～1 981.51 ng/kg in sediment samples. Compared to other studies,the PCNs concentration in soil samples of the study area was at the middle and high levels,while sediment samples was at low level.
