Anthropogenic emission of sulfur dioxide (SO<SUB>2</SUB>) in China was investigated to establish an emission inventory on air pollutants in East Asia. Major objectives of the study were to establish the emission inventory having the most detailed emission categories and regional resolution comparing with previous works, and being expandable to other air pollutants. Under popularization of desulfurization, conventinal methodologies face to limitation of data quality, but in this work the contribution of SO<SUB>2</SUB> removal by recent installation of desulfurization units was also taken into account. China was selected as the first subjective country because China has the largest emission sources of SO<SUB>2</SUB> in East Asia, which contribute a significant portion of acid deposition in Japan.<BR>By our estimation total amounts of 21 Tg of SO<SUB>2</SUB> were emitted in China in 1990. About 90% of the SO<SUB>2</SUB> came from coal combustion, and power and heat generation part was responsible for over 30% of the total discharge. The total amounts of the SO<SUB>2</SUB> emission were classified by provinces, major cities, and two grid systems such as 80×80 km square and 1°×1° resolution. Emissions in Sichian, Shandong and Jiangus provinces were ranked as the top three. Chongqing, Shanghai and Chengdu were selected to be major cities for the SO<SUB>2</SUB> emission.
