What are the hazards of automobile exhaust to humans?
2 Answers
Automobile exhaust poses the following hazards to humans: 1. Lung damage; 2. Carcinogenic effects; 3. Heart damage; 4. Brain damage; 5. Poisoning. Taking lung damage as an example, nitrogen oxides are generated inside the internal combustion engine cylinders, and their emissions depend on factors such as combustion temperature and time. They not only cause respiratory infections and reduced lung function, but also lead to chronic bronchitis, tuberculosis, asthma, neurasthenia and other diseases. Short-term exposure in children can result in coughing and sore throat. As one of the main sources of air pollution, automobile exhaust contains large amounts of harmful substances, including carbon monoxide, nitrogen oxides, hydrocarbons and solid suspended particles.
As an ordinary city resident, I often breathe in exhaust fumes on the streets and feel they pose a significant health threat. The exhaust contains harmful gases like carbon monoxide and nitrogen oxides, which can cause coughing, dizziness, and even trigger asthma, especially when concentrations are higher during traffic jams. Long-term exposure may increase the risk of lung cancer, and studies show that particulate matter can penetrate deep into the lungs, leading to cardiovascular issues. Personally, I've experienced throat discomfort after going out on polluted days, so now I try to drive less and use public transport more. Protective measures like wearing masks and improving ventilation can also reduce harm. In short, exhaust fumes directly threaten the respiratory system and affect daily life. Choosing greener transportation options is the way forward, and protecting the health of ourselves and our families is crucial.
