Abstract
In recent years, with the development of industry and transportation, the pollution of photochemical smog is getting worse. Especially, the increase of near ground ozone concentration has aroused widespread concerns. Ozone has become an important pollutant in many areas and has severe adverse health effects, especially for children, the elderly, and patients with underlying diseases. Exposure to ozone could result in sore throat, bronchial inflammation, and pulmonary emphysema via stimulating respiratory tract; induce neurotoxicity with symptoms such as headache, blurred vision, and memory impairment; and even oxidize vitamin E in skin, causing skin wrinkling and black macules. In this paper, the factors affecting environmental ozone concentrations, the health effects of ozone, and related mechanism of action were reviewed. The shortcomings of current research were summarized, aiming to provide new ideas for future studies.
