| 摘 要： | 近１０ 余年来在中国的城市地区和清洁地区进行了ＰＭ２－５ 的采集和分析，其中包括ＰＭ２－５ 的质量浓度、离子和元素成分、酸度和酸化缓冲能力以及来源解析，研究结果表明，中国大部分地区ＰＭ２－５ 的污染较重，不论是质量浓度，还是各种主要成分浓度，在ＴＳＰ 和ＰＭ１０ 中都占有很高的比重，而ＰＭ２－５ 的酸度也远远高于ＴＳＰ 和ＰＭ１０ ，特别是近年来ＰＭ２－５ 污染还有相对加剧的趋势

| Abstract: | Sampling and analysis of PM 2 5 have been carried out in municipal areas and clean areas in China during the past fifteen years,including mass density of PM 2 5 ,compositions of ions and elements,acidity and buffer ability of acidity together with source apportionment.Research showed that PM 2 5 pollution is serious in most areas in China and the acidity of PM 2 5 is much higher than that of TSP and PM 10 . Moreover,there is a trend that the PM 2 5 pollution is intensifying in recent years. |
