Acid deposition has emerged as great environmental issues of increasing concern in China. Although air pollution at South-Fujian was not severe compared with heavily polluted area, such as Chongqing and Guiyang, where precipitation of relatively high acidity was observed. In order to grasp the relation of atmospheric acidity induced by atmospheric aerosol with rainwater acidity in the district, various aerosol samples were collected in the urban and suburban area of Xiamen, Quanzhou and Zhangzhou cities in summer, 1992 and spring, 1993 and their physical and chemical characterizations were done. Then, several pollution characteristics at South-Fujian were found out. The pollution due to atmospheric aerosol was not serious, and contribution of anthropogenic sources to it was relatively low. However, contents of nitrate and sulfate ions were much higher than those of ammonium and calcium ions. Thus, the relatively high acidity and low-buffering ability of the atmospheric aerosol must be one of the important causes to induce the acidification of precipitation at South-Fujian.
