中国北方某市城区室内外细颗粒物污染特征研究
发布时间：2023-06-03 08:13
城市中个人暴露于PM2.5及其所包含的化合物情况比较复杂,来源包括居民区,商业和工业部门,个人进入各类环境暴露的总和。民居室内外空气中PM2.5暴露水平的相关研究引发关注。近年来,东北寒冷地区冬季供暖和生物质燃烧导致雾霾污染加剧。本研究旨在通过实测和模型计算的方法,研究中国北方寒冷地区室内和室外微观环境中PM2.5和PM10的污染特征,采用多种模型方法开展颗粒物污染来源解析,通过多种方法计算室外污染物的渗透率,并评估室内外颗粒物对人类健康的影响。通过实测大气环境中颗粒物的污染水平,开展PM2.5和PM10污染特征研究,结果表明:PM2.5和PM10的年平均质量浓度分别为82.4μg/m3和120.1μg/m3,相对湿度和风是影响PM2.5和PM10分布模式的主要因素。同时主要水溶性离子(NO3-...
