摘　　要：为了探明上海地区留鸟麻雀中多溴联苯醚(PBDEs)污染水平、分布模式及其区域性地理分布特征,本研究以上海为典型研究区域,检测了不同功能区域内麻雀肌肉中PBDEs的含量。结果发现,上海麻雀肌肉样品中Σ_(7)PBDEs含量(BDE 28、BDE 47、BDE 99、BDE 100、BDE 153、BDE 154和BDE 183含量之和,以脂质质量计)范围为9.0~83.6 ng·g^(-1),BDE 209最高含量达292.0 ng·g^(-1),BDE 209平均含量是Σ_(7)PBDEs平均含量的2倍左右,表明十溴联苯醚(Deca)商业品是上海地区麻雀中PBDEs的主要污染源。上海工业园区和城市中心地区样品中Σ8PBDEs含量(Σ_(7)PBDEs和BDE 209含量之和)显著高于农村地区的麻雀样品,Σ_(8)PBDEs地理空间分布遵从填埋场>工业园区>城市中心地区>城郊结合部>农村的规律,垃圾填埋场、工业园区是上海区域潜在的PBDEs的释放源。与全国其他地区相比,上海市麻雀中PBDEs含量处于较低水平,上海地区PBDEs的生态风险较小,但垃圾填埋场、工业园区和中心城区的个别麻雀样品PBDEs含量水平较高,其潜在环境风险不容忽视。This study took Shanghai as a typical research area.Eurasian tree sparrow muscles from different functional areas were selected to analyze the levels of polybrominated diphenyl ethers(PBDEs)and their geographical distribution patterns in Shanghai.The concentrations of Σ_(7)PBDEs(sum of BDE 28,BDE 47,BDE 99,BDE 100,BDE 153,BDE 154 and BDE 183 concentrations)ranged from 9.0 ng·g^(-1) to 83.6 ng·g^(-1)(lipid weight).The highest concentration of BDE 209 was 292.0 ng·g^(-1).The average concentration of BDE 209 was about twice that of Σ_(7)PBDEs.Commercial decabromodiphenyl ether products were the main source of sparrow PBDEs pollution in Shanghai.The concentrations ofΣ8PBDEs(sum of Σ_(7)PBDEs and BDE 209 concentrations)in sparrow muscle in central urban areas and industrial parks were significantly higher than that in rural areas.The geographical distribution pattern of Σ_(8)PBDEs followed the rule of landfill>industrial park>urban central area>suburban area>rural area.Shanghai waste landfills and industrial parks were potent sources of PBDEs release.Compared with other regions of China,the concentrations of PBDEs in sparrows in Shanghai were at a low level and pose relatively little ecological risk.However,the concentrations of PBDEs in individual sparrow samples from landfills,industrial parks and urban centers were relatively high,and therefore the potential environmental risk should not be ignored.
