What Are the Hazards of Automobile Exhaust?
4 Answers
Hazards of automobile exhaust: 1. Causes respiratory infections, leading to decreased lung function, chronic bronchitis, tuberculosis, asthma, and neurasthenia; 2. Induces poisoning symptoms; 3. Leads to chronic lung diseases such as emphysema and affects heart rhythm, potentially triggering myocardial infarction; 4. Causes tissue hypoxia, resulting in headaches, dizziness, slowed reactions, and decreased neural function. Reasons for excessive automobile exhaust include: 1. Obstructed air intake system, insufficient air intake; 2. Carbon deposits in the cylinder, reducing cylinder volume; 3. Low ignition efficiency of spark plugs, leading to unburned gasoline being expelled; 4. Clogged catalytic converter, obstructed exhaust, causing high backpressure in the cylinder and insufficient air intake.
I believe the most despicable aspect of car exhaust is its complete destruction of the environment. Every day when I drive to and from work, I can see the sky shrouded in a layer of gray haze. Those pungent fumes not only make the city air unbearably polluted but also release substances like nitrogen oxides, which fall to the ground as acid rain, directly corroding the flowers, trees, and ancient buildings in the parks. Animals suffer too, with fish and shrimp dying in the water and forests shrinking. Even worse, particulate matter floats in the air, clinging to leaves and preventing plants from photosynthesizing properly. Over time, the entire ecosystem becomes imbalanced. As a city resident, I choose to walk or bike more to reduce my travel and advocate for the use of new energy vehicles to cut down on this source of pollution. Protecting nature isn’t just lip service—it starts with real action. Otherwise, future generations won’t even get to see a blue sky.
As an older individual, I'm more concerned about health issues. Car exhaust poses significant harm to our respiratory systems. The harmful gases it emits, such as carbon monoxide and sulfides, directly enter our lungs, triggering coughing, asthma, and even severe cardiovascular diseases. During urban rush hours, when stuck in traffic congestion, the fumes can irritate the eyes. Long-term inhalation makes elderly people more prone to chronic respiratory problems, while children face higher risks when playing outdoors. Medical expenses also rise accordingly, increasing family burdens. In fact, regular vehicle inspections, maintenance, and replacing old parts can reduce exhaust emissions. Health is fundamental—don't neglect it for the sake of convenience.
As a parent, I am particularly concerned about the harm of exhaust emissions to children and the elderly. Children have low immunity, and inhaling those pollutants can easily lead to recurrent coughing and developmental issues. The elderly have weaker resistance, and inhaling exhaust while walking in the park can make breathing more difficult. The heavy traffic near schools results in poor air quality, which directly affects children's classroom performance. I've seen news reports that some cities have effectively controlled exhaust emissions through traffic restrictions. In daily life, I encourage families to use public transportation more and drive private cars less. This not only protects vulnerable groups but also reduces urban noise pollution.
