摘　　要：对中国某电子垃圾拆解区周边66个土壤样品中25种多溴联苯醚(PBDEs)进行了分析。结果表明,25种PBDEs总质量浓度为0.13~11.80ng/g,其中BDE209的质量浓度为0.10~11.60ng/g,占比达到了50.9%~98.3%。聚类分析和主成分分析表明,该拆解区土壤中PBDEs主要有两类来源,一类来源于八溴联苯醚商业工业品,一类来源于五溴联苯醚和八溴联苯醚商业工业品。一至六溴代的低溴代PBDEs在土壤中有一定的迁移能力,能够从高浓度地区向低浓度地区迁移,而八至十溴代PBDEs在土壤中不易迁移。Polybrominated diphenyl ethers(PBDEs)in 66 soil samples collected from an electronic waste dismantling venue were analyzed.Results showed that the mass concentrations of total 25 PBDEs were 0.13-11.80 ng/g,and that of BDE209 were 0.10-11.60 ng/g,accounting for 50.9%-98.3%.Cluster analysis and principal component analysis displayed that PBDEs in the electronic waste dismantling venue had two sources,one from decaPBDE and another from pentaPBDE and octaPBDE.PBDEs with 1-6 bromine atoms could migrate from high concentration areas to low ones.However,PBDEs with 7-10 bromine atoms hardly transferred.
