  • 摘要: 以峰江为中心，采集了台州电子垃圾拆解区域的26个表层土壤样品，调查台州地区短链氯化石蜡（SCCPs）的污染状况、空间分布和单体构成情况. 结果表明，SCCPs在所有土壤样品中均有检出，其浓度水平介于47.95—1298 ng·g-1干重，平均值为276.7 ng·g-1干重. C10和Cl6—7为土壤中SCCPs最主要的碳原子和氯原子同族体. 空间分布表明短链氯化石蜡的浓度水平总体呈现随距采样点中心峰江距离增加而减少的趋势，说明电子垃圾拆解活动可能是SCCPs的一个潜在释放源.
    Abstract: Taizhou is a major e-waste dismantling area in China. A large quantity of contaminants in the electronic and electrical equipments can be released to the ambient environment through the unregulated e-waste dismantling activities. In this study, 26 soil samples from Fengjiang, a typical e-waste dismantling site in Taizhou, were collected in 2008—2009 to investigate the pollution levels, spatial distribution and congener patterns of short chain chlorinated paraffins (SCCPs) in the soils. SCCPs were detected in all soil samples, with the total concentrations ranging from 47.95 to 1298 ng·g-1 dw (mean value of 276.7 ng·g-1). The chlorine content of SCCPs in soil samples were in the range of 59.1%—62.8%. C10 and Cl6,7 were the dominant homologue groups among all SCCPs congeners. A significant decreasing trend of the total concentrations of ∑SCCPs was found in the soil samples with increasing distance from Fengjiang, suggesting that e-waste dismantling activities might be a major source of SCCPs released to the ambient environment.
