| 摘 要： | 利用气质联用仪(GC-NCI-MS)对中国川藏地区饮用水、表土和青稞样品中PBDEs(包括十溴联苯醚在内)和TBBPA的含量进行了检测,分析了PBDE同系物的分布模式,比较研究了不同区域的溴系阻燃剂(BFRs)的污染水平、可能来源和环境影响因素.结果显示,西藏地区饮用水中均未检出PBDEs和TBBPA.表土样品中∑13PBDEs的含量范围为0.87~10.56 ng·kg-1(以干重计),PBDE主要同系物为BDE-15、209、47和99(所有样品中100%检出),分别占∑13PBDE含量的39.0%、16.5%、10.5%和10.5%.另外,研究发现,土壤中∑13PBDEs与TBBPA的含量显著相关,暗示了它们相似的空间分布,且PBDEs和TBBPA均与TOC值显著相关,PBDEs和TBBPA与海拔高度呈显著线性关系.这表明川藏地区土壤中PBDEs和TBBPA的污染为同一来源,且其含量不仅受TOC值和海拔高度的影响,也可能受与PBDE和TBBPA有关的大气传输、稀释或吸附、沉降多种因素影响.在偏远地区的农作物青稞中检测到了PBDEs和TBBPA,可能是通过大气沉降到农作物表面,被生物富集和吸收.青稞为该地区居民主食的原料,尽管PBDEs和TBBPA的含量非常低,但可能对当地居民健康产生影响.
