Abstract: To explore the concentrations,characteristics,and sources of organic aerosols in winter in Beijing,atmospheric fine particulate matter (PM2.5) samples were collected from November 10,2016 to December 10,2016.One hundred and twenty-nine particulate organic matters （POM） were quantified by gas chromatography-mass spectrometry,accounting for approximately 9.3%±1.2%of the total concentration of organic matter.The most abundant class was sugar,among which levoglucosan alone accounted for18... More
