大气臭氧:天然分布、人为影响及其健康损害

Atmospheric ozone:Natural distribution, formation potential and effects on health: A review

从大气臭氧（O3）天然分布、人为活动对O3变化的影响（臭氧层空洞和O3生成潜势）O3污染对人类健康的危害（O3污染对人体呼吸系统和心血管系统的影响）3个方面综述了近年来有关大气O3的研究进展,其中在O3生成潜势方面重点介绍了O3生成效率、光化学O3生成潜势和增量O3活性3种主要模型。通过了解本区域O3污染形成的主要来源和变化过程,引起人们对于O3污染的重视,并据此制定合理的控制政策和措施。

In order to promote people＇s awareness of atmospheric ozone changes and take protective measures, the paper reviews the latest progress of ozone research. The review includes three aspects： natural distribution of ozone, impacts of human activities on ozone variation（ozone hole and ozone formation potentials） and effects of ozone pollution on human health（especially for human respiratory system and cardiovascular system）. Three models are introduced in terms of ozone creation potentials, namely ozone creation efficiency, photochemical ozone creation potentials and ozone incremental reactivity. The object of the paper is to give some knowledge about the ozone pollutions,main sources and the change of regional ozone.
