| 摘 要： | 现场检测长沙市住宅室内空气PM2.5颗粒物浓度及其颗粒物中包含的四种主要致癌风险重金属元素含量,并运用蒙特卡罗方法分别对4种重金属元素进行致癌风险模拟与不确定性因素分析,研究发现住宅室内PM2.5颗粒物中四种致癌重金属元素的致癌风险大小排列为Cr>As>Cd>Ni,四种致癌重金属元素Cr、Ni、As、Cd的致癌风险贡献值大小为CA>ET>BW,因此应采取有效措施降低室内PM2.5浓度。 |
| 关 键 词： | 室内 PM2.5 重金属元素 致癌风险 |

| Abstract: | The concentration of PM2.5 particulate matter in indoor air and the contents of four major carcinogenic heavy metals in particulate matter of residential buildings in Changsha City were detected on the spot.The carcinogenic risk simulation and uncertainty analysis of four heavy metals were carried out by Monte Carlo method.It was found that the carcinogenic risk of four carcinogenic heavy metals in PM2.5 particulate matter was high for both men and women.The contribution value of four carcinogenic heavy metals,Cr,Ni,As and Cd,is CA>ET>BW.Therefore,measures should be taken to reduce indoor PM2.5 concentration. |
| Keywords: | indoor PM2.5 metal elements carcinogenic risk |
