抄録

Chemical constituents (Cl^-, NO₃^- , SO₄^2-, NH₄⁺) of atmospheric aerosols were measured in Fuchu, Tokyo. The mean concentrations of these constituents were 7.42, 10.12, 6.16 and 4.61 μg/m³, respectively. Nitrate aerosol concentration was extremely high, and surpassed sulfate aerosol concentration. It was ascertained that the contribution of nitrate aerosols to the air pollution was remarkable in Fuchu area, compared with other regions. The concentrations of nitrate and sulfate aerosols showed high value in summer. The relationships between aerosol concentrations and meteorological factors were discussed. Aerosol concentrations were strongly affected by predominant surface wind direction. High concentrations of any constituents were associated with southerly wind. Whereas, temperature and solar radiation have no correlation with aerosol concentrations. The comparison between chemical composition of aerosols and of precipitations was also discussed.
