摘要
2014年4—6月,在齐齐哈尔大学设立采样点,采集PM2.5样品。采用离子色谱法测定其中的主要水溶性无机离子,分析主要组成及污染来源。结果表明,齐齐哈尔市春季PM2.5平均质量浓度为46μg/m3,水溶性无机离子平均质量浓度为20.67μg/m3,占PM2.5质量浓度的42.82%。齐齐哈尔市PM2.5中二次组分主要以酸式硫酸盐形式存在。来源分析发现,PM2.5主要来源于移动源(如汽车尾气)、生物质燃烧及垃圾焚烧、固定源(化石燃料燃烧)、土壤及建筑尘。
The samples of PM2.5 were collected in the Qiqihar University of Qiqibar City from Apr. 2014 - Jun. 2014, and theconcentrations of water-soluble ions were analyzed using ion chromatography. The results showed that the daily average massconcentrations of PHI2.5 was 46 μg/m3 , and concentrations of water-soluble ions was 20. 67 μg/m3 which accounted for 42.82%of PM2.5. The sulfate was main components of secondary reactions in Qiqihar city. Concerning on the source analyzing, it wasalso detected that PM25 might be from vehicle emission sources, biomass burning, stationary source emissions, fugitive dust ofsoil and building dusts.
