Based　on　the　demand　for　a　volatile　organic　compounds　(VOCs)　emissions　inventory　for　Beijing　and　for　the　reduction　in　VOC　emissions,　the　three　major　solvent-based　industries　of　automobile　manufacturing,　furniture　manufacturing,　and　publication　printing　were　selected　for　this　study.　In　each　case,　emissions　link　negative　pressure　sampling　was　used　in　combination　with　laboratory-based　GC-MS/FID　to　obtain　the　VOC　spectra.　The　results　show　that　there　are　significant　differences　in　the　emission　of　VOCs　from　the　main　stages　of　automobile　manufacturing.　Specifically,　the　paint-coating　process　was　dominated　by　the　emission　of　oxygenated　VOCs　and　aromatic　hydrocarbons,　accounting　for　71.26%　and　27.14%　of　total　VOC　emissions,　respectively.　The　proportion　of　aromatic　hydrocarbons　emitted　during　the　varnishing　process　was　very　large　(84.10%),　which　were　mainly　composed　of　the　benzene　series.　The　differences　in　VOC　emissions　during　different　stages　of　the　furniture　manufacturing　process　were　small,　mainly　consisting　of　oxygenated　VOCs　and　aromatic　hydrocarbons,　which　accounted　for　55.08%　and　18.98%　of　the　total,　respectively.　Of　these,　alcohols　and　esters　were　the　main　components.　VOCs　emitted　from　different　stages　of　the　publication　printing　process　could　not　be　monitored　separately.　Thus,　the　VOCs　in　the　mixed　exhaust　gas　from　this　process　were　mainly　composed　of　alkanes　and　oxygenated　VOCs,　which　accounted　for　47.29%　and　44.57%　of　the　total　emissions,　respectively.　©　2019,　Science　Press.　All　right　reserved.
