Traceability analysis and inversion of atmospheric ozone pollution based on VOCs navigation and stationary source monitoring
Through the conjunctive use of online monitoring system and volatile organic compounds(VOCs)navigation vehicle,a set of rapid response,collaborative and effective atmospheric O3-VOCs traceability supervision method was constructed.First,through the online stationary pollution source monitoring system,the pollution source was determined quickly in real time to narrow the scope of investigation.Then,navigation monitoring vehicles equipped with portable Gas Chromatography-Mass Spectrometry(GC-MS)was used to monitor the navigation of VOCs in key areas,and the high TVOCs(total VOCs)points were analyzed to determine the source of VOCs.On this basis,through correlation matching,based on the time corrected online stationary source monitoring and air station O3 data,the inversion of pollution process was established,and the pollution traceability evidence chain was fixed.The proposed method can realize accurate pollution traceability and quickly determine problematic areas and enterprises.It is especially suitable for rapid diagnosis of pollution sources with short-term mutation of O3.It is an effective means for fine control of regional O3 VOCs.
