摘要:
针对臭氧(O3)污染突出的防城港市开展挥发性有机物(VOCs)观测。观测期间总挥发性有机物(TVOCs)平均体积分数为6.44×10-9,从物种浓度来说,含氧挥发性有机物(OVOCs)贡献最高,占比33%,其次是烷烃(27%)、烯烃(14%)和卤代烃(7%)。利用臭氧生成潜势(OFP)和OH自由基反应速率(LOH)对VOCs活性进行评估,结果表明OVOCs、芳烃和烯烃是防城港地区重要的活性物种,应加大减排力度。
Abstract:
Volatile organic compounds (VOCs) were observed in Fangchenggang City with prominent ozone (O3) pollution. The average volume fraction of total volatile organic compounds (TVOCs) during the observation period was 6.44×10-9. In terms of species concentration, the contribution of oxygen-containing volatile organic compounds (OVOCs) is the highest, accounting for 33%, followed by alkanes (27%), olefins (14%) and halogenated hydrocarbons (7%). The activity of VOCs was evaluated by ozone formation potential (OFP) and OH radical reaction rate (LOH). The results showed that OVOCs, aromatics and olefins were important active species in Fangchenggang area, and emission reduction should be strengthened.
