WebbAtmospheric volatile organic compounds (VOCs) measurement was carried out using gas chromatography-flame ionization detector (GC-FID) technique (Airmo VOCs online analyzer) in a typical urban area in Beijing from April 2014 to January 2015. Ambient levels, variation characteristics and influential factors contributing to the formation of near … Webb1 apr. 2015 · where MIR is the maximum incremental reactivity [39, 40]. Table 2 shows the photochemical reactivity of the measured NMHCs with the OH radical and also their contribution to the photochemical ozone in the measurement site. The study reveals that alkenens contribute more to the total OFP than alkanes.
