BIOSIS COPYRIGHT: BIOL ABS. The emission of polycyclic aromatic hydrocarbons (PAHs) from various industrial stacks (blast furnace, basic oxygen furnace, coke oven, electric arc furnace, heavy oil plant, power plant and cement plant) in southern Taiwan were investigated. PAH concentrations (mug m3) and PAH emission factors (mug/kg feedstock) were determined. In addition to these eight stationary industrial stacks, an industrial waste incinerator, a diesel engine and a gasoline-powered engine were selected and combined for the identification of source indicatory-PAHs in this study. The qualitative contribution of PAHs to the ambient air by various sources was estimated by factor analysis. Combustion of heavy oil produced considerably higher 4, 5 and 6 + 7-ring PAH concentration than other stacks. In addition, the HMW (higher molecular weight) PAH concentrations were significantly higher for the coke oven, the electric arc furnace and heavy oil combustion. Measured total-PAHs emission factors of eigh
