摘　　要：目的了解浙江省典型污染地区河塘底泥和鲫鱼中二噁英和多氯联苯的污染状况。方法样品加入同位素标记内标物,经有机溶剂提取浓缩后,再经凝胶色谱、多层硅胶柱和氧化铝柱净化,以高分辨气相色谱高分辨质谱仪测定二噁英和多氯联苯残留。结果5个地区河塘底泥和鲫鱼中二噁英和多氯联苯的浓度范围分别为379.6～9811.6pg/g干重、10000～762433pg/g干重和0.084～12.168pg/g湿重、149.03～57304pg/g湿重;总毒性当量范围为11.2～2162pg/g干重和0.234～39.251pg/g湿重。结论二噁英和多氯联苯在5个地区的底泥和鲫鱼中均有不同程度的检出,但以路桥地区为最严重,废旧电器拆解产业是当地环境中多氯联苯的主要排放源,该地区二噁英类物质的污染状况已不容忽视。Objective To reveal the pollution status of PCDD/Fs and PCBs in sludge and crucian from typical polluted areas of Zhejiang Province.Methods After having been spiked the 13 C-labeled surrogate internal standards,the extracts were purified by a series of columns like GPC,multiple silica columns and alumina columns,and then analyzed by HRGC-HRMS. Results Concentration ranges of dioxins and PCBs in sludge and Crusians from five areas were 379.6-9811.6pg/g dry weight,10 000-762 433pg/g dry weight and 0.084-12.16...
