Continuous monitoring of fine particulate matter in school classrooms and assessment of students' exposure level

  • 摘要:   目的  了解学校室内PM2.5污染状况和学生暴露水平,为学生健康防护提供基础数据。  方法  通过在线环境监测仪对佳木斯8所中小学16间自然通风教室的PM2.5进行为期2个学期的连续监测,同时抓取室外PM2.5数据进行对比研究,对学生在校期间暴露量进行评价。  结果  春、秋两学期教室内PM2.5平均质量浓度分别为(26.93±24.7)和(31.85±30.37) μg/m3,教室内外PM2.5 I/O值分别为0.92和0.95,存在强相关性。两学期所有教室的全天PM2.5平均质量浓度为(28.93±26.85)μg/m3,略高于白天学生在校期间的(27.53±26.53)μg/m3,且工作日质量浓度高于周末。随着楼层升高,室内PM2.5质量浓度逐渐下降。学生在校期间的累积暴露量,春季学期为28.48 μg /m3,秋季学期为31.87 μg /m3  结论  教室内PM2.5随时间、水平空间与垂直空间的变化会有所不同,且室内PM2.5的污染程度极大依赖于室外污染源;春、秋两学期学生在校期间PM2.5暴露量有所差异。
