Abstract

In East Asia, China's economy is growing rapidly and consequently emission of air pollutants are increasing rapidly. A large amount of Non methane volatile organic compounds(NMVOCs) cmission is accompanied by NOx emission will increase the oxidation potential in the atmosphere to promote sulfuric acid and nitric acid production from SOx and NOx, respectively. NMVOCS emission amounts were eompiled for China, Korea, Japan and Taiwan. NMVOCS emission amount from all artificial sources is 14815Gg/y. Combustion source is the major contributor(13201Gg/y, (89.l%)) followed by evaporative source including gasoline vehicles(1614Gg/y, l0.90%). East Asian emission including China, Japan, South Korea and Taiwan is estimated as 18.5Tg/y and China's emission aeeount for around 80%.
