Abstract:		"In this study, typical industries that act as sources of volatile organic compound (VOCs) emission in Sichuan, including automobile manufacturing, wooden furniture, wood-based panel manufacturing, and paint production, were selected and GC-MS national standard analysis to study the organized emission VOC components of every procedure. The spectra of VOCs in the automobile industry were obtained by means of total emission normalization. The results showed that the VOC components of automobile manufacturing, wooden furniture, and oil paint manufacturing enterprises were mainly aromatic hydrocarbons and oxygen-containing compounds, accounting for more than 70% of total VOCs; the emissions from automobile part manufacturing enterprises were mainly aromatic hydrocarbons, with a ratio of over 90%. The proportion of oxygen-containing compounds in the wood-based panel manufacturing industry was found to be up to 97%, mainly caused by the emission of formaldehyde, which accounts for 75%, followed by isopropanol, acetone, and other substances. The proportion of aromatic hydrocarbon and olefin in synthetic resin enterprises is relatively high at over 80%. The olefin species are mainly 1,3-butadiene and 1-butene. Although there are some differences in emission species between different industries, they are mainly composed of aromatic hydrocarbons and oxygenates. Therefore, it is necessary to improve the identification and control of components with high concentration, activity, and toxicity for aromatic hydrocarbons and oxygenates. The source, process, and end process control should be monitored to achieve the effect of total emission reduction"
