1 Answers
14-year-old cars comply with either China IV or China V emission standards. The hazards of vehicle exhaust include the following two points: 1. Automobile exhaust contains hundreds of different compounds: The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides, etc.; 2. While directly harming human health, exhaust also impacts the environment of human life: Sulfur dioxide in the gas has a strong irritating odor. When it reaches a certain concentration, it can easily lead to acid rain, causing soil and water sources to acidify, affecting the growth of crops and forests.
