摘要: Abstract Photochemical aging of volatile organic compounds (VOCs) in the atmosphere is an important source secondary aerosol (SOA). To evaluate formation potential SOA at urban site Lyon (France), outdoor experiment using a Potential Aerosol Mass (PAM) oxidation flow reactor (OFR) was conducted throughout entire days during January-February 2017. Diurnal variation formations and their correlation with OH radical exposure (OHexp), ambient pollutants (VOCs particulate matters, PM), Relative Humidity (RH), temperature were explored this study. Ambient air exposed to high concentration radicals OHexp range (0.2–1.2)×1012 molecule/(cm3•sec), corresponding several weeks equivalent atmospheric photochemical aging. The results informed that has potency contribute SOA, these productions favored from rather than via ozonolysis. Maximum (36 µg/m3) obtained about 7.4 × 1011molecule/(cm3•sec), approximately 5 oxidation. between environment conditions (RH & temperature, VOCs PM) observed. It first time estimate over long period Lyon.
