In addition, in order to effectively cope with composite air pollution characterized by ozone pollution, this year, the city's first announcement of the announcement of the special emission limit of gas pollutants in the province will be released in the province. The particulate matter is 10 mg per cubic meter, 35 mg of sulfur dioxide per cubic meter, and 50 mg of nitrogen oxides per cubic meter.
