Abstract. Sugar compounds (SCs) are major water-soluble constituents in atmospheric aerosols. In this study, we investigated their molecular compositions and abundances in the northern receptor site (Mangshan) of Beijing, China, to better understand the contributions from biogenic and anthropogenic sources using a gas chromatography–mass spectrometry technique. The sampling site receives anthropogenic air mass transported by southerly winds from Beijing, while relatively clean air mass transported by northerly winds from the forest areas. Day- and nighttime variations were analyzed for anhydrosugars, primary sugars, and sugar alcohols in autumn 2007. Concentrations of overall SCs ranged from 30.8 to 875 ng m−3 (avg. 325 ng m−3), showing diurnal variations with higher levels in daytime (351 ng m−3) than nighttime (276 ng m−3). Interestingly, biomass burning (BB) tracers were more abundant in nighttime than daytime, while other SCs showed different diurnal variations. Levoglucosan was found as a dominant sugar among the observed SCs, indicating an intense influence of BB over Mangshan. The levels of fungal tracers (arabitol and mannitol) were higher in daytime than nighttime, suggesting a significant transport of fungal spores and microbes to the receptor site by atmospheric transport from Beijing area. The plant emissions from Mangshan forest park significantly control the diurnal variations of glucose and fructose. The pollen tracer (sucrose) showed a clear diurnal variation, peaking in daytime due to higher ambient temperature and wind speed. We found that soil dust contributes to trehalose in daytime while microorganisms were responsible to its emissions in nighttime. The meteorological parameters (relative humidity, temperature and rainfall) significantly affect the concentrations and diurnal variations of SCs. Positive matrix factorization analysis suggested that local BB and bioaerosols transported from Beijing area were significant sources of SCs. (289)

Short summary
We studied aerosol samples collected in Autumn 2007 with day/night intervals in a rural site of Mangshan, north of Beijing, for sugar compounds (SCs) that are abundant organic aerosol components and can influence the air quality and climate. We found higher concentrations of biomass burning (BB) products at night- than daytime, whereas pollen tracers and other SCs showed an opposite diurnal trend. Because this site is meteorologically characterized by mountain/valley breeze.
