| 中文摘要: |
| 针对当前全国性雾霾频发的问题，本文在合肥地区大学生群体中开展PM2.5暴露水平研究，基于问卷调研所获得的大学生活动模式基础数据，结合主要微环境浓度实测结果，开展大学生个体和单位体重潜在暴露剂量的评估工作。研究发现，大学生每天超过50%的时间在宿舍度过，教室占1/5；秋、冬、春三季中除宿舍和图书馆外的其他微环境平均浓度皆超过相关环境标准，并且所有微环境室内外PM2.5浓度I/O比皆大于1；颗粒物暴露贡献最高的微环境为教室和宿舍，两者各占总量的27%；个体潜在暴露剂量影响因素中，体重>性别>年级>季节>工作日/周末；单位体重潜在暴露剂量影响因素中，性别>体重>年级，季节和工作日/周末与单位体重潜在暴露剂量不呈显著相关性。 |

| Since haze weather has dominated recently, based on a questionnaire survey in college students of Hefei city and a series of tests in the typical microenvironment, assessments of college students’ exposure to PM2.5 in Hefei were carried out. The results show that college students spend more than half of their time in the dormitory and 1/5 in the classroom. Average concentrations of these microenvironment exceed national standard except in the dormitory and library in the autumn, winter and spring seasons, but I/O ratio is all higher than 1. Classroom and dormitory have the maximum exposure contribution, each accounting for 27%. For influence factors of potential exposure level of each individual, the importance ranks as weight> gender > grade > season > weekdays/weekends. For weight-specific, gender> weight> grade, season and weekdays/weekends are not significantly correlated with potential exposure level of weight-specific. |
