In　order　to　study　the　VOCs　emissions　characteristics　of　fastener　industry　and　its　impact　on　air　quality,　typical　industries　were　selected　and　a　sampling　project　was　conducted.　102　species　of　VOCs　were　analyzed　utilizing　GC-MS/FID.　The　VOC　spectrums　of　fastener　industries　were　established.　The　emission　inventory,　emission　factors　and　its　impact　on　air　quality　were　estimated.　Results　indicated　that　the　alkane　was　the　dominant　component　of　VOCs　in　all　processes　of　fastener　industries　with　proportions　ranging　from　29.58%　to　68.94%.　Alkanes　including　n-dodecane,　ethane　and　propane,　aromatic　hydrocarbons　including　o-xylene　and　p-xylene,　and　oxygenated　hydrocarbons　including　butyl　acetate　and　acetaldehyde　were　the　components　with　high　emission　load.　Aromatics　were　the　major　contributors　to　the　potential　of　ozone　generation,　while　alkanes　were　the　main　contributor　to　the　formation　potential　of　secondary　organic　aerosols.　The　VOCs　emission　factor　of　the　fastener　industry　was　1.51kg/t.　The　national　annual　VOCs　emissions　of　fastener　industry　from　2018　to　2020　were　11,　496.84,　13,　301.89　and　14,　365.69　tons　in　respective,　with　the　annual　growth　rate　of　11.85%.　©　2022,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
