The atmospheric fine particulate matter (PM2.5) is one of the main air pollutants and there have been numerous investigations involving chemical composition analyses and concentration measurements of the atmosphere. However, it would be not enough to understand the chemical compositions and sources of PM2.5. This paper reviews recent research and trend for levoglucosan measurement in PM2.5 as a tracer from biomass burning, and summarizes the results of the chemical transformation in atmospheric processes.
