Preliminary Study of PCBs and PBDEs in Indoor Air Samples Collected from Typical Houses in Shanghai

  • 摘要: 于2008年12月─2009年3月用PUF被动采样器采集了上海市6个典型家庭室内的空气样本,利用GC-EI-MS和GC-NCI-MS法分别测定了样本中14种多氯联苯(PCBs)和7种多溴联苯醚(PBDEs)的质量浓度,采用GC-ECD法测定了ρ(BDE-209). 结果表明:ρ(PCBs)为313.84 ~ 753.79 pg/m3,平均值为442.09 pg/m3;ρ(PBDEs)为0.62 ~83.35 pg/m3,平均值为21.83 pg/m3;ρ(BDE-209)为114.9~ 221.19 pg/m3,平均值为185.58 pg/m3. 与文献报道相比,上海市家庭室内空气中ρ(PCBs)处于中等水平,ρ(PBDEs)略低,但ρ(BDE-209)明显高于其他地区. 儿童和成人对PCBs的日均暴露量达到1 980和4 772 pg/d,对PBDEs的日均暴露量达到930和2 241 pg/d. PCBs和PBDEs能够引起人体生物毒性效应,因此,作为在室内空气中普遍存在的有机污染物,其持续低剂量的暴露应引起重视.
