With　the　continuous　adjustment　of　the　national　industrial　structure　and　the　strengthening　of　the　rigid　requirements　for　industrial　enterprises　to　settle　in　parks，the　number　of　high-tech　industrial　parks　with　high-tech　as　the　pillar　industry　continues　to　increase.　To　analyze　the　impact　of　VOCs-related　high-tech　industries　on　the　environmental　quality　of　parks，Beijing＇s　typical　high-tech　industrial　parks　were　selected　as　research　cases，and　the　BCT-7800A　PLUS　volatile　organic　compounds　online　monitoring　system　was　used　to　monitor　115　types　of　VOCs　in　the　park　environment.　The　pollution　level　and　ozone　generation　potential　of　VOCs　in　the　park　environment　were　analyzed，and　the　hazard　index（HI）and　lifetime　carcinogenic　risk（Risk）of　toxic　VOCs　were　calculated.　The　environmental　VOCs　at　different　sites　in　the　park　were　detected　using　gas　chromatography-mass　spectrometry　/　hydrogen　ion　flame　detector（GC-MS　/　FID）and　high-performance　liquid　chromatography（HPLC），and　the　pollution　characteristics　of　environmental　VOCs　at　different　sites　were　analyzed.　The　research　results　indicated　that：①　during　the　continuous　monitoring　period，the　high-tech　industrial　park　φ（TVOCs）was（72.　71　±　52.　51）×　10−9，and　the　main　contributing　components　of　VOCs　were　alkanes　and　OVOCs，accounting　for　38.　3%　and　21.　8%，respectively.　They　were　mainly　affected　by　fuel　combustion　sources，and　the　average　OFP　of　the　park　was　404.　13　µg·m−3.　②　The　health　risk　assessment　showed　that　the　non-carcinogenic　risk（HI）caused　by　toxic　VOCs　in　the　park　during　continuous　monitoring　was　below　1，which　was　at　an　acceptable　level.　The　average　carcinogenic　risk　of　1，2-dichloroethane　exceeded　the　safety　threshold，indicating　that　the　species　had　a　carcinogenic　risk.　The　average　values　of　trichloromethane，1，2-dibromoethane，1，2-dichloropropane，and　benzene　were　below　the　safety　threshold，but　the　highest　value　exceeded　the　safety　threshold，indicating　that　these　four　species　also　had　a　carcinogenic　risk　during　specific　high-emission　periods　and　need　to　be　given　special　attention.　③　Offline　sampling　detection　results　showed　the　characteristics　of　the　environment　at　different　sites　in　the　park.　The　average　value　of　φ（TVOCs）was（37.　62　±　11.　01）×　10−9.　The　volume　fraction　of　VOCs　at　four　sites　was　higher　than　that　of　other　urban　environmental　monitoring　sites　in　the　study（30.　34　×　10−9）.　The　average　OFP　value　was　246.　38　µg·m−3.　The　OFP　at　five　monitoring　sites　was　higher　than　that　at　urban　monitoring　sites，indicating　that　the　VOCs　emitted　by　high-tech　enterprises　in　the　park　had　a　certain　impact　on　the　environment.　©　2024　Science　Press.　All　rights　reserved.
