PRELIMINARY INVENTORY OF SULFUR-DIOXIDE EMISSIONS IN EAST-ASIA

A preliminary sulfur dioxide emissions inventory for East Asia was developed. The annual emissions rate for fossil-fuel related sulfur was estimated for a 80 km mesh grid using energy consumption and industrial activity data for the region. The total sulfur dioxide emissions from this area as sulfur were about 11.5 TgS y-1, almost equal to the emissions in north-western Europe or the north-eastern U.S. which are regions where acid deposition occurs. Emissions from mobile sources were found to be relatively small, while coal-fired stationary sources contribute a large part of the sulfur dioxide emissions in East Asia.
