Abstract: When the relative magnitudes of air pollutants are arranged on a map, the local distribution of the each pollutant becomes apparent. This approach will be clues revealing the emission sources, behaviors and impacts of pollutants. Of ambient VOCs, passive air sampler will be useful device for the sampling because of highly portable, sensitive, and selective feature. The spatial distribution patterns in an industrial area were quite different from each targeted VOC, indicating that those emission sources are specific for each VOC. Similar trend has been observed in the distribution of the ambient PAHs in an industrial area. It indicates that the high-polluted distributions were apparently contributed to the industrial plants such as paper-making factories. On the other hand, the local distributions of ambient PAHs in urban city showed that the highly polluted areas were spread along the busy roads of the outer city, with an enclosed area of lower pollution in the central city. In certain industrial area, the lifetime cancer risks of exposure to ambient VOCs were significantly higher in winter than in summer, which were derived mainly from benzene, carbon tetrachloride, formaldehyde, and acetaldehyde. The carcinogenicity of ambient PAH mixture was occupied (~77%) by BaP, DBahA, and Nap in both summer and winter.
