Is vehicle pollution primarily noise pollution followed by exhaust pollution?

[SanOwen]

It is incorrect to say that vehicle pollution is primarily noise pollution followed by exhaust pollution. Typically, vehicle pollution is mainly caused by exhaust emissions, with noise pollution being secondary. Exhaust pollution: Vehicle exhaust pollution refers to environmental pollution caused by the emission of waste gases from automobiles. The main harmful gases emitted include hydrocarbons, nitrogen oxides, carbon monoxide, etc. Measures to prevent and control exhaust pollution mainly include improving vehicle fuel economy, enhancing the quality of gasoline used in vehicles, reducing the olefin content in gasoline, and developing advanced exhaust purification technologies. Noise pollution: When vehicles are driven on roads, internal combustion engines, horns, tires, etc., produce a large amount of unwanted sounds, including engine noise, transmission system noise, intake system noise, exhaust system noise, tire noise, and aerodynamic noise.
