Concentration Levels and Personal Exposure Characteristics of Black Carbon in a Shanghai Subway Station

  • 摘要: 基于对职业环境空气污染物的个体暴露风险关注,在上海某地铁站进行了ρ(黑碳)的连续定点(新风井和车辆控制室)监测;同时对地铁工作人员进行个体黑碳暴露采样,并与定点监测的ρ(黑碳)比较,探讨个体采样在黑碳暴露研究中的作用. 结果表明:某地铁站新风井处ρ(黑碳)与ρ(NO2)呈显著相关(R=0.75,P<0.05),而与ρ(PM10)无显著相关性(R=0.43,P>0.1);由ρ(黑碳)日变化及其在工作日和休息日的差异可知,地铁站内ρ(黑碳)可能与室外机动车尾气排放相关;与定点监测结果不同,个体黑碳暴露浓度波动范围大,出现了未在定点监测中观测到的极高值,并且个体黑碳暴露浓度的四分位差值(IQR)是定点监测结果的2倍;尽管车控室内平均个体黑碳暴露浓度较低,但由于个体72%的工作时间是在车控室内度过的,因此车控室的个体黑碳暴露剂量比非车控室环境高.
