摘要
近年来,各地、各部门贯彻落实国家"大气十条"方案,持续加强大气污染防治,空气质量明显改善。但随着PM2.5浓度大幅下降,近地面臭氧污染问题日益凸显,已经成为影响空气质量达标率的关键因素。从近地面臭氧浓度的时空变化特征、臭氧污染的主控因子、前体物VOCs的化学反应活性、排放来源、臭氧暴露对人群的健康效应等方面,详细介绍了国内外关于近地面臭氧污染的主要研究方法和进展,针对现有研究的不足,进行了总结并指出了未来的研究趋势。
In recent years, all localities and departments have implemented the National Action Plan for Air Pollution and Prevention, and the air quality has improved significantly. However, with the sharp decline in PM_(2.5) concentration, the problem of surface ozone pollution has become increasingly prominent, and been a key factor affecting the air quality compliance rate. The characteristics of the temporal and spatial changes of ozone concentration, the main control factors of ozone pollution, the chemical reactivity of precursor VOCs, the emission sources, and the health effects of ozone exposure on the population were introduced in detail. The main research methods and progress, in light of the deficiencies of existing research, are summarized and the future research trends are pointed out.
