  • 摘要: 利用高效液相色谱-串联四极杆质谱分析了我国四川省中北部地区（成都、德阳、绵阳）表层土壤中六溴环十二烷（HBCD）的浓度水平和分布特征. 成都、德阳、绵阳等3个地区土壤中HBCD的平均浓度分别为77.0 pg·g-1 dw（-1 dw）、48.9 pg·g-1 dw（-1 dw）、121 pg·g-1 dw（25.0—334 pg·g-1 dw）. HBCD具有较高的检出率（83.3%），但与欧洲、亚洲其他国家及我国东南部沿海地区相比，HBCD污染仍处于较低水平. 土壤中HBCD异构体以γ-HBCD为主，且平均组成与工业品相似. 工业区污染物浓度最高，其次为城市、郊区和农田，表明城市和工业活动可能是HBCD的潜在污染源.
    Abstract: HBCD in surface soils from Chengdu, Deyang and Mianyang city in Sichuan Province was analyzed using a high performance liquid chromatography coupled with triple quadrupole mass spectrometer (HPLC-MS/MS). The average concentrations of HBCD were 77.0 pg·g-1 dw (dry weight) (-1 dw), 48.9 pg·g-1 dw (-1 dw) and 121 pg·g-1 dw (25.0—334 pg·g-1 dw) in soils from Chengdu, Deyang and Mianyang, respectively. The high detection frequency of HBCD (83.3%) suggest ubiquitous existence in these areas. Compared to Europe, other countries in Asia and the southeast coastal regions of China, HBCD concentrations in soils from the three cities are at relatively low level. γ-HBCD was the predominant isomer in the soils, which is very similar to those in the industrial products of HBCD. The HBCD concentrations in soils from industrial parks were the highest, followed by those from urban sites, rural sites and farmlands, indicating that the urban and industrial activities might be the potential sources of HBCD.
