摘要: In this study, tropical cyclones over the East and South China Seas were found to be the most predominant weather conditions associated with the occurrence of high ozone (O-3) episodes in Hong Kong in 2005-2009. A photochemical trajectory model coupled with Master Chemical Mechanism (MCM) was adapted to simulate the O-3 concentrations during two O-3 pollution episodes. The results agreed well with the observed data. A representative backward air mass trajectory was used to determine the contribution of each volatile organic compound (VOC) to the O-3 levels. After taking into account both reactivity and mass emission of each VOC, 10 species were found to be the key O-3 precursors in Hong Kong. Further analysis identified solvent related products accounting for 70% of the modeled O-3 concentration in Hong Kong. The results highlight the importance of considering together reactivity and source sector emissions in developing targeted VOC reduction for O-3 abatement strategies.
