摘要
本文利用美国的EPA健康风险评价模型以及参数不确定性的蒙特卡诺模拟,对株洲市居民住宅室内外的PM2.5污染来源对人体暴露于颗粒物的健康风险进行研究。结果表明:人们受PM2.5暴露的健康风险中,室内暴露风险是室外暴露风险的8.5倍。Mn元素对人体存在一定非致癌风险,Cr存在致癌风险,Co元素的非致癌和致癌风险表现为室内贡献最大,Cr元素室外贡献最大。
The paper aims to investigate the effect of indoor and outdoor PM2.5 pollution sources of residents on human health in Zhuzhou city,using the EPA health risk assessment model in United States and Monte Carlo simulation with uncertain parameters.The results indicate that indoor exposure risk is 8.5 times the risk of outdoor exposure.Different elements have different cancer risk.Mn has certain non-carcinogenic risks to human and Cr has carcinogenic risk.What’s more,the results reveal that Co has the highest risk of non-carcinogenicity in indoor,but Cr is the most risky outdoor.
