摘要
我国甲苯生产量大,且用途广泛,研究以某园区为例,采用美国环境保护局(US EPA)吸入风险评估模型,针对园区周边人群(非职业人群)开展甲苯吸入的健康暴露风险评估。结果表明,基于目前甲苯单一污染物的暴露水平,以暴露时限70 a,估算的甲苯最大危害商为3.81×10^(-3),空气中甲苯的最大允许暴露浓度为1.97×10^(3)μg·m^(-3),远高于目前园区大气中实测的甲苯浓度。此外,结合国内外对甲苯的管控策略和园区环境管理的需求,提出下一步对园区甲苯环境风险的管控对策建议。
The production of toluene in China is large with wide application.Taking an industrial park as an example,we adopted the inhalation risk assessment model developed by United States Environmental Protection Agency(US EPA)to conduct the health exposure risk assessment of toluene inhalation by people around the industrial park(non-occupational group).The results showed that if basing on the current exposure level of toluene,the single pollutant with the exposure duration of 70 years,the estimated maximum harm factor of toluene will be 3.81×10^(-3),and the maximum allowable exposure concentration of toluene in the air will be 1.97×10^(3)μg·m^(-3),which is much higher than the measured concentration of toluene in the air at present.In addition,we provided the suggestions of the control countermeasures for the environmental risk of toluene in the park combining with the domestic and international control of toluene and requirements for the environmental management of the park.
