美日臭氧污染问题及治理经验借鉴研究

Research on the Ozone Pollution and Control Measures in US and Japan

以臭氧(O_3)为主要成分的"光化学氧化剂"是光化学烟雾的真身。臭氧污染受臭氧前体物排放及其复杂的相互转化关系控制,导致臭氧污染问题在治理过程中具有高度的复杂性和反复性,甚至成为全球性环境难题。我国城市群臭氧污染问题继PM2.5污染后日趋突出,本文探讨和总结了美国洛杉矶、日本东京等大都市在污染治理方面的经验,以期为我国构建更加全面、科学、系统的治理体系推进臭氧污染防治工作提供借鉴。

The“photochemical oxidant”with ozone(O3)as the main component is the true body of photochemical smog.Because of ozone pollution controlled by the exposure of ozone precursors and their complex interactions,it is highly complex and repetitive in the governance process and even becomes a global environmental problem.The problem of ozone pollution in China’s city clusters is becoming increasingly prominentaccompanied by PM2.5.In this paper,experiences in pollution control in Los Angeles and Tokyo wereexplored and summarized in order to build a more comprehensive,scientific and systematic management system to promote the prevention and control of ozone pollution in China.
