According to the relevant statistics of the Environmental Protection Agency, the ratio of PM2.5 transmission sources outside China is about 34%~40%, the ratio of domestic pollution sources is about 60%~66%, and the impact ratio of mobile sources among domestic pollution sources is about 30%~37%. %, industrial sources are about 27%~31%, and other pollution sources are about 32%~43%. Among them, particulate pollutants emitted by diesel vehicles in mobile sources are one of the main pollution sources affecting air quality. The county’s diesel engine is the main source of mobile pollution, reducing its pollution emissions and reducing the health hazards caused by air pollution to the county residents.
