Abstract：According to atmospheric environment bulletin data released by the Ministry of Environmental Protection of China, the air quality in China’s urban areas was not optimistic by 2013. In order to fully understand the changes and factors of ambient air quality in Liaoning Province, China, the thesis focused on the impacts of TSP, PM10, PM2.5 and 8 hours of ozone of the cities’ air pollution based on the monitoring data of particulate matters in five typical cities of the province, Shenyang, Dalian, Anshan, Fushun, and Jinzhou City. Results show that, except 8 hours of ozone, concentrations of TSP, PM10 and PM2.5 in the five cities all exceed the second level limit of national ambient air quality, respectively higher than 0.14－0.44 times, 0.57－0.91 times and 0.96－1.53 times. As toseasonal changes, TSP, PM10, and PM2.5 concentrations in winter and spring are generally higher than those in summer and autumn in the studied cities, and 8 hours of ozone concentrations in spring and summer are higher than those in autumn and winter. The Pb and Zn contentsare the highest two of the atmospheric particulate matters of the five cities, and the metal elements are enriched in PM2.5. Though TSP, PM10, and PM2.5are the major pollutants of urban air,the impact of 8 hours of ozone concentrations to urban air are also should not be neglected, and it may become a major pollutant instead of fine particulate matters.
