Sampling of aerosol particles using filter papers at the top of Mt. Teine (1,024 m a.s.l.) and on the campus of Hokkaido University in Sapporo City, Hokkaido, Japan was carried out in relation to the wind direction from August to October, 1986. The concentrations of Carbon, SO^<2->_4, NO^-_3, NH^+_4, Cl^- and metal elements (Al, Na, Cu, Ni, K, Zn, Ca, Mn, Mg and Cd) were measured to reveal the characterization of source of the air pollution according to wind direction considering the meteorological parameters at both sites. Soil elements show a higher concentration than those of anthropogenic or marine origin, and which decreased with rainfall. The marine, aerosol amounts in the urban area were higher than those on the mountain site. All concentrations of each element measured were in no way affected by the wind direction and the difference of altitudes during summer period.
