Abstract:Theidentificationofsourcesof Volatile Organic Compounds(VOCs)pollution inurbanatmospheric environments is dificult.Qingzhou Ecological EnvironmentMonitoring Centerof Weifang cityhas developedaVOCsonline monitoring andtraceabilitytechnologysystembasedonmulti-sourcedatafusion.Duringthis proces,ahierarchicalmonitoring network is constructedtoobtain high spatiotemporalresolutiondata,a VOCscharacteristic informationdatabase is established, andatraceabilityalgorithmbasedonchemicalcomponentcharacteristicsandspatiotemporalcorrelationsisdesignedto achieve eal-time monitoringandaccurate traceabilityofregional VOCspolltion.Practicalapplication hasshown that this technology system can improve the accuracy of VOCs pollution source identification to at least 85% ， providing strong technical support for precise pollution control.
