摘要
文章对某电子垃圾拆解场地及周边土壤以及河流沉积物进行了采样检测,分析了土壤和沉积物样品中PCDD/Fs的污染程度,结果显示周边土壤样品检出浓度为1.2~7.4 ng TEQ/kg,均值为3.3 ng TEQ/kg,焚烧场区浓度为12 ng TEQ/kg,拆解区浓度为2.4ng TEQ/kg;沉积物样品检测浓度为0.34~0.96 ng TEQ/kg。PCDD/Fs污染来源主要是电子垃圾焚烧过程,其污染特征符合国内其他垃圾焚烧过程污染特征,污染程度也和国内其他垃圾焚烧场所相近。
Samples were collected near E-waste dismantling sites and analyzed for polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs). The concentration of PCDD/Fs in soil which is near E-waste dismantling ranged from 1.2 to 7.4ng TEQ/kg, and the average concentration is 3.3 ng TEQ/kg. The concentration of PCDD/Fs in soil of incineration and dis-mantling sites are 12 ng TEQ/kg, 2.4 ng TEQ/kg, and 0.34 to 0.96 ng TEQ/kg in sediment. Respectively, the waste incinera-tion in this study area is the main emission resource of the PCDD/Fs. Compared with the other domestic waste incineration plants, the pollution features and the degree of contamination are similar to them.
