Abstract:Samples of individual particle were collected around Svalbard island during 8-12August, 2013. Physicochemical characteristics of 2530 aerosol particles were analysed through transmission electron microscopy (TEM) coupled with an energy-dispersive X-ray spectrometer (EDS). Arctic aerosol particles were classified as five types: sea-salt, S-rich, Fe-rich, carbonaceous and mineral dust particles. Air masses showed either atmospheric circulation in the arctic ocean or transport of air from Svalbard and Greenland. Samples collected under the air mass of the arctic ocean mainly contained sea-salt particles (54.7% of total in the samples). Mineral dust may be transported from the land, because samples of air mass from Svalbard and Greenland were dominated by mineral dust particles (95.4% of total particles in the samples). We estimated the PM2.5 mass concentration ranging from 0.55mg/m3 to 0.72mg/m3 in Arctic atmosphere.
