Measurement of low volatile aerosol-forming substances characteristics in shore of the baikal lake

摘要

Conversion of atmospheric gas admixtures into aerosol during chemical and emission processes is one of the major and still unresolved problems of atmospheric physics and chemistry.Low mass concentration of aerosol-forming substances (AFS) in absolute value and compared to the existing aerosol mass concentration provides the main experimental difficulty.Water-absorption technique for determination of low volatile atmospheric admixtures in concentration down to lng/m~3 was developed to resolve these problems (Ankilov et al.,2000).The method in combination with measurement of aerosol microphysical parameters allows estimation of total productivity of local AFS sources in the atmosphere and other physical and chemical properties.This paper presents the results of the recent field measurements.
