【摘要】 结合北京市再生水利用工程,建立了再生水用于公园绿化、道路降尘和冲洗作业时,职业人群和公众的暴露评价方法和评价模型,通过现场调研和监测分析,首次提出了再生水利用暴露人群的再生水日摄入量和终生日均暴露剂量,为健康危险度分析提供定量依据.其中公园绿化职业人群通过皮肤和吸入的日均总摄入量为0.07L/d,公众为0.04~0.05L/d,消毒副产物的日均暴露剂量为:职业人群经呼吸途径终生日均暴露剂量为2.8×10-7~1.2×10-5mg.(kg.d)-1,经皮肤渗入途径终生日均暴露剂量为5.8×10-8~2.4×10-6mg.(kg.d)-1;公众经呼吸途径终生日均暴露剂量为1.1×10-7~6.8×10-6mg.(kg.d)-1.更多还原

【Abstract】 The exposure assessment method and model of various reclaimed water uses are built combining with Beijing reclaimed water project.Firstly the daily ingesting dose and lifetime average daily dose(LADD) of exposure people are provided via field work and monitoring analysis,which could be used in health risk assessment as quantitative reference.Take park irrigation as a example,for occupational workers,the total daily ingesting dose is 0.07L/d,LADD of disinfection by-products(DBPs) via the respiratory route is 2.8×10~-7～1.2×10~-5mg·(kg·d)~-1,LADD of DBPs via the dermal route is 5.8×10~-8～2.4×10~-6mg·(kg·d)~-1.For common people,the total daily ingesting dose is 0.04～0.05L/d,LADD of DBPs via the respiratory route is 1.1×10~-7～6.8×10~-6mg·(kg·d)~-1.更多还原
