摘要: 本文通过在WMO GAW 区域大气本底污染监测站-临安大气本底污染监测站采集的气溶胶样品的化学成分的分析结果,分别用Malm(1994)和Stelson(1981)提出的方法(分别记为Malm方法和Stelson方法)重建气溶胶质量浓度,并与称重获得的质量浓度进行对比,发现虽然Stelson和Malm方法所考虑的物质组成及所使用的化学成分个数并不相同,其计算结果略有差异,但总的来说两种方法都能较好的反映绝大部分的气溶胶质量,在实际应用中可以根据所分析的化学成分数据情况和研究的目的采用不同的质量重建方法。

Abstract:

Based on the data of aerosol chemical compositions obtained at WMO GAW (World Meteorological Organization Global Atmospheric Watch) station in eastern China-Lin’An regional background air pollution monitoring station, two methods (referred as Malm method and Stelson method) that were described by Malm (Malm et al.,1994) and Stelson (Stelson and Seinfeld, 1981) were used to study the mass closure (or mass reconstruction) of sampled aerosols. The inter-comparison of reconstructed aerosol masses with the gravimetric masses showed good agreements, although the two methods used different chemical composition species. The mass closure indicated that both methods could identify most of aerosol masses sampled during the experiment. This study suggested that based on the interests or objectives of the specific study, both of the Malm method and the Stelson method could be used for the aerosol mass closure.

Key words: aerosol mass reconstruction, Malm method, Stelson method
