摘    要:利用同位素稀释高分辨气相色谱-高分辨质谱(HRGC/HRMS)的分析方法研究了东北某钢铁厂及其周围生活区、背景对照区土壤中二噁和多氯联苯污染物的污染水平和分布规律。结果表明,土壤中二噁的浓度和毒性当量分别为26pg/g(6.02~109pg/g)、0.72pg I-TEQ g-1(0.008~5.43pg I-TEQ g-1)。土壤中多氯联苯的浓度为955pg/g(268~3504pg/g),毒性当量值达0.07pg TEQ g-1(0.006~0.33pg TEQ g-1)。该区域土壤中的二噁和多氯联苯浓度明显低于一般国家居住地的土壤控制标准,处于较低的污染水平。

关 键 词:二恶英  多氯联苯  钢铁厂  土壤  高分辨气相色谱-高分辨质谱联用

Abstract:The concentrations and distribution patterns of PCDD/Fs and PCBs were investigated in the soil from an iron and steel making plant, and the surrounding residential area and background areas, Northeastern China. The concentrations and TEQ values of PCDD/Fs were 26pg g-1(6.02~109pg g-1) and 0.72pg I-TEQ g-1(0.008~5.43pg I-TEQ g-1). The PCBs levels in the soil were 955pg g-1 (268~3504pg g-1), with the TEQ values of 0.07pg TEQ g-1(0.006~0.33pg TEQ g-1). The concentrations of PCDD/Fs and PCBs in this study were in a low level and were lower than the national soil quality guidelines for developed countries.
Keywords:PCDD/Fs  PCBs  Rron and steel making plant  Soil  HRGC/HRMS
