The fingerprint and emission factors are established and the emission inventories are estimated. Furthermore, the health risk and ozone formation potential for these emission sources are analyzed. The sources are classified as 16 according to AP-42. The results show that the TVOC emission concentration are 59 ~ 3514 ppb for cogeneration boiler, coal-fired boiler, oil-fired boiler and iron manufacturing; TVOC emission concentration are 49 ~ 12985 ppb for organic solvent process, synthetic resin, and polyester resin manufacturing process; TVOC emission concentration are 66 ~ 275 ppb for aluminum foundry and steel foundry process; the other are 170~21106 ppb. Aromatic are the most common group in these emission sources, which accounts for 51% emissions. For organic solvent process, synthetic resin, and polyester resin manufacturing process, carbonyls are the dominant group, which accounts for 46.1~90.4%. Toluene, acetone, ethyl acetate, benzene and methyl ethyl ketone are the most common species. For boilers, isobutene, n-butane and propene are the characteristic species. 1-Butene, ethanol and cis-2-butene are characteristic species for steel making process. . The TVOC emission factors are 57.5 g/ton-coal for cogeneration boiler; 0.71, 0.18 and 8.38 g/ton-coal for power plant; 0.54, 2.31 and 0.76 g/ton-coal for coal-fired boiler; 31.5, 0.35 and 49.1 g/ton-oil for oil-fired boiler; 9.37 g/ton-sinter ore for iron manufacturing. TVOC emission factors are 65.8, 57.8, 32.7 and 0.51 g/ton-solvent for organic solvent process; 0.003 and 0.06 g/ton-resin for synthetic resin manufacturing process; 0.002 and 0.54 g/ton-stock for polyester resin manufacturing process; 0.008, 0.01 and 0.08 g/ton-aluminum for aluminum foundry; 0.0001 and 0.006 g/ton-steel for steel foundry process. Stencil printing has the highest ozone formation potential (OFP) (1894 g O3/ton). Based on the same TVOC emission, the ozone formation potential is highest for steel making process, followed by polyester resin, stencil printing boiler and tape manufacturing. Slope factor (SF) and reference concentration (RfC) from USEPA IRIS and Cal. EPA are used for health risk analysis. Based on the same TVOC emission, steel making has the highest potential to cause cancer. For non-cancer risk analysis, steel making has the highest potential as well.
