Chemical composition of atmospheric aerosol collected at Syowa Station

Atmospheric aerosol samples were collected at Syowa Station, Antarctica, on a 47mm millipore filter with 0.45μm pore size, using an air-pump. Air sampling volumes ranged from 10m^3 to 30m^3,which were collected about 30m windward of the Laboratory of Environmental Science at Syowa Station. After tha...

Enrichment factor is defined as the element/Al ratio in atmospheric aerosol samples divided by the element/Al ratio in crustal rocks based on the table of MIYAKE (Elements of Geochemistry, Maruzen, 290p, 1965). For the trace elements such as Mn, Fe, Zn and Cu, enrichment factors at Syowa Station are the same order of magnitude as the value at the South Pole in the southern hemisphere and over the North Atlantic Ocean in the northern hemisphere reported by ZOLLER et al.
