摘　　要：为改善污染物人体暴露的评估方法,研究了哈尔滨大气环境中多溴联苯醚(PBDEs)的暴露情况,评估各形态PBDEs单体经皮肤每日摄入量,利用多粒径气/粒分配公式与皮肤摄入量公式,实现对粒径影响下颗粒态PBDEs经皮肤每日摄入量的预测。结果表明,哈尔滨大气PBDEs经皮肤摄入量为71.6 pg/d,颗粒态和气态PBDEs的经皮肤摄入量相当,分别为32.8和38.8 pg/d,BDE-209是经皮肤摄入的主要单体。受颗粒物质量浓度影响,供暖期的PBDEs经皮肤摄入量高于非供暖期。颗粒态PBDEs的经皮肤摄入量由粗颗粒主导,其中传质系数为主要影响因素。本研究首次提出预测粒径影响下颗粒态PBDEs经皮肤摄入量的方法,并应用哈尔滨、上海和广州的监测数据进行验证,证明之前推导的恒稳态多粒径气/粒分配公式可以很好地预测粒径影响下颗粒态PBDEs的经皮肤摄入量。To improve the assessment of human exposure to pollutants,the exposure of atmospheric polybrominated diphenyl ethers(PBDEs)in Harbin was investigated,and the daily dermal intake of PBDEs with various phases and particle sizes was evaluated.Using size-resolved G/P partitioning equation and dermal intake formula,a method that can predict the size-dependent daily dermal intake of particulate PBDEs in atmosphere was proposed.The daily dermal intake of atmospheric PBDEs in Harbin was 71.6 pg/d,where the dermal intake of particulate PBDEs was similar to that of gaseous PBDEs,with their intakes 32.8 and 38.8 pg/d respectively.The dermal intake of BDE-209 was dominant.Considering the effects of the total suspended particle concentrations,the dermal intake of PBDEs was higher during heating period than that during non-heating period.The dermal intake of particulate PBDEs was dominated by the coarse particles,and the mass transfer coefficient was the main factor.It was the first time that this study explored a method to predict the size-dependent dermal intake of particulate PBDEs.The method was verified by using the monitored data in Harbin,Shanghai,and Guangzhou,which proves that the derived size-resolved G/P partitioning equation under steady state can be well applied to predict the size-dependent dermal intakes of particulate PBDEs.
