辽宁省典型城市空气中挥发性有机物健康风险评价

美国综合风险评估系统(IRIS)提供了污染物的参考剂量(RFD)和污染物参考浓度(RfC)的相关数据,但某些化合物的RFD和RfC数据不全,造成了风险评价的困难,基于RFD的风险评价很难确定污染物由呼吸系统的准确摄入量。应用SPSS软件剖析了RFD和RfC的相关性,提出了以RfC为基础的风险评价体系,与RFD评价结果对比表明:基于RfC的风险评价更能准确反映VOCs污染的风险。尝试应用RFD和RfC值对沈阳、鞍山、抚顺、葫芦岛四个城市空气中VOCs进行非致癌健康风险评价。

The U.S.Integrated Risk Assessment System（IRIS）provides a reference pollutant dose（RFD）and reference concentration of pollutants（RfC）of the relevant data,but some of the compounds of RFD and RfC incomplete data,resulting in a risk assessment of the difficulties,RFD based on risk assessment of pollutants from the respiratory system is difficult to determine the accuracy of intake.In this paper,analyzed the correlation of RfC and RFD by using SPSS software,proposed RfC-based risk assessment system,compared with the RFD evaluation,the results show that：the risk assessment based on RfC could more accurately reflect the risk of VOCs contamination.Try to apply values of the RFD and RfC on cities of Shenyang,Anshan,Fushun,Huludao for VOCs in urban air non-carcinogenic risk assessment.
