摘要
随着全球气候变化问题的日益严重,我国做出了“双碳”目标的承诺。目前,我国尚未从根本上解决PM_(2.5)污染问题,与此同时,O_(3)污染逐渐加剧,各地PM_(2.5)和O_(3)复合污染事件频发。因此,持续改善PM_(2.5)和O_(3)污染问题对保护人民健康和实现碳中和目标方面具有重要意义。为了更好地理解和应对PM_(2.5)污染问题,本文概述了NO x和NH 3排放以及二次有机气溶胶对PM_(2.5)污染的影响;同时,总结了当前排放源(氮氧化物、挥发性有机物)和气象要素(温度、相对湿度、紫外辐射强度、风速和边界层高度等)对O_(3)污染影响的研究,为改善我国O_(3)污染以及制定减排策略提供方法和理论支撑。此外,综述了我国在PM_(2.5)和O_(3)复合污染区域研究、化学影响机制以及协同减排等方向的研究进展,旨在为我国空气质量改善以及“双碳”背景下PM_(2.5)和O_(3)复合污染的协同治理提供相关参考和指导。
As the global climate change problem is becoming more and more serious,China has made the commitment to the"dual-carbon"target.At present,our country has not fundamentally solved the issue of PM_(2.5)pollution.Meanwhile,O_(3)pollution is gradually worsening,and incidents of combined PM_(2.5)and O_(3)occur frequently.Therefore,the sustained improvement of PM_(2.5)and O_(3)pollution is of great significance to protect people's health and achieve carbon neutrality goals.To better understand and address PM_(2.5)pollution,this paper provides an overview of the effects of NO x and NH 3 emissions,as well as secondary organic aerosols on PM_(2.5)pollution.Additionally,it summarizes current research on the influence of emission sources(nitrogen oxides,volatile organic compounds)and meteorological factors(temperature,relative humidity,UV radiation intensity,wind speed,boundary layer height,etc.)on O_(3)pollution in China,which provides methodological and theoretical support for improving O_(3)pollution and developing reduction strategies in our country.Furthermore,this paper summarizes the research progress on the regional delineation,chemical mechanism and influencing factors of PM_(2.5)and O_(3)combined pollution in China,aiming to provide relevant references and guidance for China's follow-up action plan to improve air quality,protect the environment,and realize the synergistic management of PM_(2.5)and O_(3)combined pollution under the"dual-carbon"policy.
