According to the fast industrial development and a lot of fossil fuel consumption, the emission of sulfur oxide, nitrogen oxide, ozone and particulate matters have continuously increased. In particular, urban air pollution problems have dominantly issued in China. In 2013, many provinces and cities in China were influenced by serious dust haze that extremely caused low visibility and air quality. To inhibit this environmental problem, China’s State Council issued a policy document, such as the Ten Measures of the State Council in June, 2013 and officially released the Action Plan for Air Pollution Prevention and Control (the Action Plan) in September at the same year, which was the forth road map for the nation’s air pollution prevention and control efforts for the period of 2013-2017. Subsequently, Chinese central and local governments promulgated a series of policies, laws, regulations, standards and technical guidelines to implement the Action Plan. And specific indicators are as follows. By 2017, the concentration of urban Particulate Matters (PM10) is going to be reduced by 10% compared to PM10 concentration of 2012. In addition, Chinese government will try to promote increase of annual number of days with fairly good air quality. Meanwhile, concentration of fine particulate matter (PM2.5) in Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta region is going to be reduced by approximately 25%, 20% and 15%, respectively. Especially, annual PM2.5 concentration in Beijing is planned to be controlled below 60 mg/㎥.
