采集了杭州市城北老工业区土壤样品（8个）、新工业区土壤样品（5个）和旅游区土壤样品（2个）,检测土样中17种二恶英有毒异构体的同系物毒性当量,初步获得了城区土壤二恶英的质量分数分布特性.分析结果显示,老工业区土壤的二恶英质量分数较高,毒性当量I-TEQ为0.65～41.75pg/g,平均值为12.73pg/g.新工业区和旅游区的土壤二恶英质量分数较低,土壤中二恶英毒性当量分别为0.61～1.33pg/g和1.53～2.11pg/g,平均值分别为1.07pg/g和1.81pg/g.有毒同系物毒性当量分析显示,老工业区土壤毒性当量最大贡献者是八氯代二恶英（OCDD）,占总量的33.6%,主要原因可能为OCDD在环境中较其他有毒同系物稳定,也说明老...

The concentrations of 17 polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) congeners as well as tetra-to-octa-homologues were determined in 8 soils in the old industrial area, 5 soils in the new industrial area and 2 soils in the tourism area from Hangzhou. The levels of PCDD/Fs in urban soils were primarily obtained. The I-TEQ values of soils in old industrial area ranged 0.65~41.75 pg/g with average 12.73 pg/g, which is higher than the other two areas. The I-TEQ values of soils in the new industrial area and tourism area ranged (average) 0.61~1.33 pg/g (1.07 pg/g)...
