The　measurement　of　volatile　organic　compounds　(VOCs)　was　conducted　during　November　2014　in　the　suburban　area　of　Beijing,　China,　covering　the　period　of　the　Asia-Pacific　Economic　Cooperation　(APEC)　meeting　period.　The　VOCs　characteristics　and　source　apportionment　were　analyzed.　The　average　mass　concentrations　of　VOCs　were　27.6　+/-　19.7　mu　g/m(3)　during　the　sampling　period,　and　aromatics　and　alkanes　were　the　most　abundant　VOCs　species　in　atmospheric　environment　in　Beijing　which　were　12.2　+/-　10.3　mu　g/m(3)　and　11.3　+/-　7.5　mu　g/m(3),　respectively.　The　hourly　variation　of　VOCs　was　found,　with　the　highest　concentration　occurring　at　8:00　to　9:30　and　lowest　at　12:30　to　14:00.　The　sampling　period　was　divided　into　two　periods:　period.　represent　the　period　without　emission-reduction　measures,　and　period.　represent　the　period　with　reduction　measures.　The　VOCs　concentrations　during　the　period.　was　31.0%　lower　than　period..　The　Maximum　Incremental　Reactivity　(MIR)　method　was　applied　to　analysis　the　ozone　formation　potential　(OFP).　The　OFP　of　VOCs　from　period.　was　1.6　times　higher　than　period.,　and　the　majority　of　VOCs　species　were　alkenes　and　aromatics.　Positive　matrix　factorization　was　applied　to　estimate　contributions　of　potential　VOCs　sources.　The　vehicle　exhaust　emission　was　the　major　source　of　VOCs　during　the　two　periods,　and　the　contribution　to　VOCs　was　5.7%　lower　during　period.　than　period.　due　to　the　emission-reduction　of　vehicle　operation.　Copyright　(C)　2016　Turkish　National　Committee　for　Air　Pollution　Research　and　Control.　Production　and　hosting　by　Elsevier　B.V.　All　rights　reserved.
