大气污染是人类面临的重大环境挑战。我国大气污染具有高度的复合污染特征,其形成过程既有高强度的颗粒物均相成核现象,又有多介质非均相致霾过程,同时耦合了强的大气氧化性以及O3污染,是不同于洛杉矶光化学烟雾和伦敦烟雾的新型“霾化学”烟雾污染。“霾化学”区别于并突破现有的理论认识,是解析我国典型多介质复合污染环境下PM2.5成因以及PM2.5与O3污染间非线性复杂关系,综合研究气、液、固多介质非均相过程的大气污染化学。研究“霾化学”过程对精准控制我国乃至其他国家大气复合污染意义重大。本文提出和总结了大气“霾化学”概念,并对“霾化学”理论的完善和发展进行了展望。

关键词： 霾化学, 复合污染, 多介质界面化学, 臭氧, PM2.5

Air pollution is a major challenge for the humankind. Under the highly complex air pollution conditions in China, strong homogenous nucleation and multiphase heterogeneous processes coexist, coupling with strong atmospheric oxidizing capacity and ozone pollution. This complex air pollution, different from the “London smog” and the “Los Angeles photochemical smog”, is a new type of “haze chemistry smog” pollution. “Haze chemistry” distinguishes from traditional homogeneous chemistry by surpassing its existing theoretical understandings. It is a type of air pollution chemistry that comprehensively studies the gas-liquid-solid multiphase processes, revealing the formation mechanism of PM2.5 and the non-linear relationship between PM2.5 and O3 under typical multi-medium complex air pollution conditions. Understanding “haze chemistry” processes is crucial for precise control of complex air pollution in China and other countries. Here, we propose and summarize the concept of “haze chemistry”, and discuss its further improvement, development, and application.

Key words: haze chemistry, air pollution complex, interface chemistry, ozone, PM2.5
