Automobile exhaust poses the following hazards to humans: 1. Causes respiratory infections and leads to decreased lung function; 2. When concentration exceeds standards, it can cause poisoning symptoms; 3. Affects heart rhythm and may induce myocardial infarction; 4. Mild cases cause headaches, dizziness, and slowed reactions, while severe cases lead to decreased neurological function; 5. At certain concentrations, it can cause poisoning or even death. The main pollutants in automobile exhaust are carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, lead compounds, benzopyrene, and solid particulate matter, which can cause photochemical smog. The CO, NOx, SOx, unburned hydrocarbons (HC), particulate matter (PM), and odorous gases emitted by vehicles pollute the air and pose significant hazards to humans, animals, and plants.
