[Source Composition Spectrum of Volatile Organic Compounds in Typical Industries in Sichuan].

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%.
