| 摘 要： | 短链氯化石蜡(SCCPs)是一类新的持久性有机污染物(POPs),目前我国相关研究较少。为了解SCCPs在土壤中的污染现状和分布特征,测定了24个广州土样(含3个剖面采样点)中SCCPs的含量,分析了其同族体分布模式。结果表明:广州表层土壤中SCCPs的含量变化范围为6.8～541.2ng/g,均值为79.6ng/g;剖面土壤中SCCPs的含量范围为7.5～115.8ng/g,均值为33.1ng/g。不同类型土壤中SCCPs各同系物组分的分布模式相似,以碳原子数为10和11的Cl6-SCCPs/Cl7-SCCPs为主。

| Abstract: | Short-chain chlorinated paraflqns （SCCPs） are a new kind of persistent organic pollutants （POPs）, on which the studies are insufficient in China. In this paper, to control the pollution situation and distribution of SCCPs in soils, 24 soil samples from three sampling sections in Guangzhou were determined. The distribution modes of SCCPs homologues were analyzed. The results showed that in Guangzhou the SCCPs content in surface soil ranged in 6. 8 - 541.2 ng/g with an average value of 79. 6 ng/g and that for the profile soil ranging in 7. 5 - 115.8 ng/g with an average value of 33. 1 ng/g. The SCCP homologues were distributed similarly in different kind of soil, mainly consisting of C16-SCCPs/C17- SCCPs with 10 or 11 carbon atoms. |
