Secondary organic aerosol (SOA) formation from a cyclohexene ∕ NOx systemwith various SO2 concentrations under UV light was investigated to studythe effects of cyclic alkenes on the atmospheric environment in pollutedurban areas. A clear decrease at first and then an increase in the SOA yield wasfound with increasing SO2 concentrations. The lowest SOA yield wasobtained when the initial SO2 concentration was in the range of30–40 ppb, while higher SOA yield compared to that without SO2 couldnot be obtained until the initial SO2 concentration was higher than85 ppb. The decreasing SOA yield might be due to the fact that the promotingeffect of acid-catalysed reactions on SOA formation was less important thanthe inhibiting effect of decreasing OH concentration at low initial SO2concentrations, caused by the competition reactions of OH with SO2 andcyclohexene. The competitive reaction was an important factor for SOA yieldand it should not be neglected in photooxidation reactions. The compositionof organic compounds in SOA was measured using several complementarytechniques including Fourier transform infrared (FTIR) spectroscopy, ionchromatography (IC), and Exactive Plus Orbitrap mass spectrometer equipped withelectrospray interface (ESI). We present new evidence that organosulfateswere produced from the photooxidation of cyclohexene in the presence ofSO2
