In　this　study,　the　measurement　of　volatile　organic　compounds　(VOCs)　was　conducted　at　Beijing　Capital　International　Airport　(ZBAA)　and　a　background　reference　site　in　four　seasons　of　2015.　Total　concentrations　of　VOCs　were　72.6　+/-　9.7,　65.5　+/-　8.7,　95.8　+/-　11.0,　and　79.2　+/-　10.8　mu　g/m(3)　in　winter,　spring,　summer,　and　autumn,　respectively.　The　most　abundant　specie　was　toluene　(10.1%-17.4%),　followed　by　benzene,　ethane,　isopentane,　ethane,　acetylene,　and　n-butane.　Seasonal　variations　of　VOCs　were　analyzed,　and　it　was　found　that　the　highest　concentration　occurring　in　summer,　while　the　lowest　in　spring.　For　the　diurnal　variation,　the　concentration　of　V005　in　the　daytime　(9:00-15:00)　was　less　than　that　at　night　(15:00-21:00)　obviously.　Ozone　Formation　Potential　(OFP)　was　calculated　by　using　Maximum　Incremental　Reactivity　(MIR)　method.　The　greatest　contribution　to　OFP　from　alkenes　and　aromatics,　which　accounted　for　27.3%-51.2%　and　36.6%-58.6%　of　the　total　OFP.　The　WRF-CMAQ　model　was　used　to　simulate　the　impact　of　airport　emissions　on　the　surrounding　area.　The　results　indicated　that　the　maximum　impact　of　VOCs　emissions　and　all　sources　emissions　at　the　airport　on　O-3　was　0.035　and　23.8　mu　g/m(3),　respectively.　Meanwhile,　within　1　km　from　the　airport,　the　concentration　of　O-3　around　the　airport　was　greatly　affected　by　airport　emitted.　(C)　2018　Published　by　Elsevier　Ltd.
