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.
