摘要
针对大气气溶胶质量浓度的测量在城市污染监测中的重要性,提出了利用双角度光学粒子计数器测量大气气溶胶质量浓度的方法,该方法利用气溶胶粒子体积谱和密度来计算气溶胶质量浓度,可以对不同粒径范围的气溶胶质量浓度进行计算,最后采用2004年9月和2007年11月在北京测量的数据对计算的PM_(10)和PM_(2.5)进行验证,证明此方法是可行的。该方法对使用光学方法测量气溶胶质量浓度具有参考意义。
The mass concentration of aerosol particles is important for studying aerosol pollution. A method of retrieving mass concentration of aerosol particles is advanced with dual-scattering-angle optical particle counter, and the relationship is established among mass concentration, size distribution and density of aerosol particles. The method was validated by results measured at September 2004 and November 2007 in Beijing. It indicated that the method of retrieving mass concentrations of PM10 and PM2.5 is feasible, which supplied references to measure aerosol mass concentration using optical method.
