What types of vehicles are targeted by environmental traffic restrictions?
1 Answers
Environmental traffic restrictions primarily target vehicles that exceed exhaust emission standards. Below is a detailed introduction about automobile exhaust: 1. Overview: Automobile exhaust refers to the waste gases produced during vehicle operation, containing hundreds of different compounds. The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, sulfur oxides, etc. 2. Hazards: Sulfur dioxide in the exhaust 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 and affecting the growth of crops and forests. Meanwhile, exhaust gases can directly harm human health.
