在定义暴露人群和综合考虑各项暴露途径的情况下,利用概率分布暴露模型分别对国内城市中普通人群和职业人群(电子废弃物回收从业人员)对多溴联苯醚(PBDEs)的人体暴露情形进行了模拟和评估。结果显示:职业人群的潜在暴露量为普通人群潜在暴露量的3～5倍,暴露量的分布与现有人体内暴露的实例研究结论取得了较好的一致性。普通人群的PBDEs最高暴露量约为20 000 ng,而2%的职业人群高于此值,极端高值可达60 000 ng。在研究的5种PBDEs同系物中,BDE-209的比例最高。
In the definition of exposed population and comprehensive consideration of various exposure ways, the probability distribution exposure model was applied to the human exposure of PBDEs to the general population and occupational population (e-waste recycling practitioners) in cities in China Simulation and evaluation. The results showed that the potential exposure of occupational population was 3-5 times of the potential exposure of the general population, and the distribution of exposure had a good agreement with the existing case studies of human exposure. The highest exposure of PBDEs in the general population is about 20,000 ng, while in 2% of the occupational population it is above this value and the extreme high value is 60,000 ng. Among the five PBDEs studied, the highest proportion of BDE-209 was found.
