  • 摘要: 为掌握室内外细颗粒物（PM2.5）污染特性，监测采集西安市某办公场所室内外PM2.5样品，统计分析PM2.5质量浓度特征，探究室内外PM2.5相关性、微观形貌以及矿物组成的差异。结果表明：室内外PM2.5年均质量浓度分别为85.32和109.83 μg·m-3，冬季污染尤为严重。室内PM2.5受室外PM2.5影响显著，室内外PM2.5质量浓度的相关系数为0.890 0。室内PM2.5多为粒径小于1 μm的球状颗粒物，而室外颗粒物形状、大小不规则，室内外PM2.5均含有大量的碳、氧元素，其他元素的种类和含量存在一定差异。室内PM2.5中矿物多为非晶态物质，室外PM2.5主要由石英、赤铁矿和碳酸钙等矿物质组成。
    Abstract: To investigate the pollution characteristics of indoor and outdoor PM2.5, samples were collected in an office building in Xi'an. Characteristics of PM2.5 mass concentration were analyzed, indoor and outdoor PM2.5 correlation, morphology and mineral composition were explored. The results showed that the average annual mass concentration of PM2.5 indoor and outdoor were 85.32 μg·m-3 and 109.83 μg·m-3, respectively. The pollution was the most serious in winter. Indoor PM2.5 were affected by outdoor PM2.5 significantly and the correlation coefficient was 0.890 0.Indoor PM2.5 consisted of particle size less than 1 μm and spherical particles, whereas the shape and size of outdoor PM2.5 were irregular. Carbon and oxygen elements were predominant for both indoor and outdoor PM2.5 while the species and amount were different. Indoor PM2.5 was mostly made up of amorphous compounds while outdoor PM2.5 contained some crystalline materials such as quartz, hematite and calcium carbonate.
