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. The Hualien County Environmental Protection Bureau continued to implement the 111-year “Hualien County Diesel Vehicle Inspection Plan” this year. For various diesel vehicle control-related businesses, its main work is to handle smoke station inspection, roadside inspection and inspection, diesel vehicle oil product inspection and various administrative related work, and assist in the promotion of the establishment of the first jurisdiction in accordance with the major policies of the Environmental Protection Agency. Owners of old and large diesel vehicles in Phases 1 to 3 shall cooperate with the central policy to apply for subsidy and propaganda operations such as replacement of old vehicles, pollution repairs, and installation of air pollution control equipment, so as to continue to maintain good air quality in the county.
