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。

关 键 词:大气污染  大气气溶胶  PM_(2-5)  酸性降水

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.
Keywords:atmospheric pollution  atmospheric aerosol  PM    2  5  acidic precipitation
