Seasonal variation of carbonaceous and metal compositions of atmospheric aerosols at Syowa Station, Antarctica in 2001
Antarctic aerosols collected at Syowa Station in 2001 were analyzed to investigate their seasonal variations and long-range transport of anthropogenic aerosols. The measured chemical species were elemental carbon and organic carbon, and metals such as Al, V, Cr, Mn, Fe, Co, Ni, Zn and Pb. Concentrat...
