Is vehicle pollution primarily noise pollution followed by exhaust pollution?

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.
As an urban commuter who drives frequently, I believe car pollution is definitely not primarily a noise issue. Sitting in traffic jams during daily commutes, the constant engine humming is indeed annoying, but what truly worries me is exhaust pollution. Look at the black smoke or gray fumes coming from vehicle tailpipes - they're filled with carbon dioxide, carbon monoxide, and even fine particulate matter that directly enters the air and our lungs. Every breath feels slightly irritating, and I have friends who were hospitalized for asthma caused by exhaust fumes. While noise is bothersome, you can mitigate it by closing windows or using earplugs, whereas exhaust is omnipresent, especially at congested urban intersections. Statistically, the global annual death toll from air pollution (with vehicle emissions being a major contributor) far exceeds noise-related health cases. So in my personal experience, exhaust emissions should be the primary concern, with noise being secondary - though it does affect quality of life, particularly when highway roaring keeps you awake at night. We're all looking forward to widespread electric vehicle adoption to resolve this dilemma.
As an environmentally-conscious individual, I must emphasize that vehicular pollution—specifically exhaust emissions—should be the primary focus. Recall those hazy urban smog days when grayish air quality alerts predominantly stemmed from automobile emissions like nitrogen oxides and volatile organic compounds, which exacerbate the greenhouse effect and trigger respiratory illnesses. In contrast, noise pollution tends to be more localized, such as modified cars roaring past at midnight disturbing residents. However, regarding overall environmental impact, exhaust emissions have far wider coverage, even permeating rural areas. Health risk data indicates urban residents face higher probabilities of chronic diseases due to exhaust exposure, whereas noise mainly causes indirect issues like irritability or insomnia. Although engine sounds and honking stand out prominently in bustling city centers, I maintain that exhaust pollution should rank first as it directly threatens ecological balance and human survival. Promoting low-emission or new energy vehicles remains the solution for mitigation.
Having lived in the city for decades, I often see cars coming and going, but I feel that exhaust pollution is definitely more severe than noise pollution. When going out to buy groceries, the smell of exhaust on the street is more pungent than noise and easily triggers coughing. As for noise, like honking, although it gives me a headache, wearing headphones or going indoors can make it stop. Exhaust is different—it invisibly pollutes the air, and prolonged inhalation can lead to lung diseases. Statistically, air pollution (dominated by exhaust) is one of the major global health risks. So, noise comes second, and exhaust issues should be prioritized. After all, in daily driving, engine noise is just background, while exhaust poses a real health threat.
