| 摘 要： | 采用GC-MS/MS技术对长江3条支流(沱江、藕池河下游和松澧洪道)在不同水期的81个表层水样进行分析.实验发现样品表层水样中PCB8、18和28是优势污染物.∑PCBs在沱江、藕池河下游和松澧洪道3条支流不同水期表层水中的几何均值分别为1.96~2.59 ng ·L-1、1.84~2.54 ng ·L-1和1.52~2.38 ng ·L-1,含量均低于美国EPA连续暴露基准(14 ng ·L-1).实验结果与国内外相关文献报道值相比较,显示该研究区域表层水中PCBs浓度处于较低水平,癌症风险评价结果表明饮用该区域水摄入PCBs而带来的风险为0.15×10-7~0.26×10-7,说明研究区水样中因PCBs污染引起的癌症风险较低.
