VOCs　samples　from　workshops　and　outlets　were　collected　from　four　types　of　typical　industrial　coating　industries　in　Hebei　Province,　102　VOCs　species　were　detected　and　analyzed,　and　the　VOCs　emission　characteristics　of　workshops　and　outlets　in　four　industries　were　obtained.　The　results　showed　that　VOCs　emission　concentrations　vary　greatly　among　different　industries　due　to　the　influence　of　type　of　coating,　usage　amount　and　other　factors.　Aromatics　and　oxygenated　VOCs　were　the　main　components　in　furniture　manufacturing,　vehicle　manufacturing　and　special　equipment　manufacturing　industries,　accounting　for　14.7%~88.3%　and　10.1%~64.7%,　respectively.　The　proportion　of　halo-hydrocarbons　in　metal　products　industry　was　59.2%~86.9%.　The　end-of-pipe　treatment　had　the　greatest　effect　on　aromatics,　and　the　proportions　of　toluene,　ethylbenzene,　xylene,　trimethylbenzene,　butyl　acetate　and　2-butanone　at　the　outlets　were　significantly　lower　than　that　in　the　workshops.　The　contributions　of　aromatics　to　ozone　formation　potential　(OFP)　and　secondary　organic　aerosol　formation　potential　(SOAP)　were　the　highest,　and　the　end-of-pipe　treatment　had　a　significant　reduction　effect　on　OFP,　SOAP　and　source　reactivity　(SR).　The　differences　in　the　SR　of　various　sources　were　obvious,　and　it　is　suggested　to　strengthen　the　control　of　industries　with　high　SR　value.　©　2022,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
