抄録

The acidity and buffering ability to precipitation acidification of atmospheric aerosols collected in Northern and Southern China and South-Kanto, Japan were measured and discussed in consideration of the local features (emission sources, soil characteristics, developing states of area, etc.) and the particle size. Generally, the acidity of water solution suspending aerosols collected in South-China was much higher than it in North-China and for the buffering ability, the inverse relation to the acidity was observed. For the size-segregated aerosols collected at several cities in China, the acidity was decreased with the increase in particle size, whereas the buffering ability was increased. These results indicated that the H<SUP>+</SUP> concentrations (aerosol acidifies) and Δ C<SUB>b</SUB> concentrations (aerosol buffering abilities) in aerosol-suspended water solutions varied largely, due to local site influences such as local supply of crust materials and gaseous ammonia, distance from industrial emission sources, topography, weather condition, and transportation of acidic pollutants.
