The Impact of Automobile Exhaust Emissions on the Environment?
2 Answers
Automobile exhaust emission standards are currently at the China IV level. The following are the harmful substances in automobile exhaust and their hazards: Harmful substances in automobile exhaust: Automobile exhaust contains hundreds of different compounds, including pollutants such as solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides. Hazards of automobile exhaust: While directly endangering human health, exhaust emissions also have profound impacts on the environment of human life. Sulfur dioxide in the exhaust has a strong irritating odor and can easily lead to the occurrence of "acid rain" when reaching certain concentrations, causing soil and water sources to acidify and affecting the growth of crops and forests.
As someone concerned about environmental issues, I often think about the impact of vehicle exhaust emissions on ecosystems. The carbon dioxide and other greenhouse gases in the exhaust accumulate in the atmosphere, exacerbating global warming and triggering extreme weather events, such as frequent floods and droughts. The air quality in our cities is also deteriorating rapidly, with dust and particulate matter floating in the air. Trees and plants grow more slowly after absorbing these pollutants, while rivers and lakes become acidified, threatening fish survival. I remember last summer when the number of birds in the park noticeably decreased—experts said this was directly related to exhaust emissions. In the long run, this pollution also degrades soil quality, affects agricultural yields, and threatens the stability of the food chain. We must promote public transportation and shared mobility to mitigate these effects, or the beauty of our planet will continue to fade.
