Cars pollute air, water, land and soil. Car exhausts emit a wide range of gases and solid matter, causing global warming, acid rain, and harming the environment and human health. Engine noise and fuel spills also cause pollution.
Vehicle emissions contribute to unbelievable and irreversible effects to human health. Nitrogen oxides (NOx), Carbon monoxide (CO),Sulphur dioxide (SO2), Benzene and Formaldehyde are the deadly chemicals emitted.
NOx are created during combustion. Vehicle engines burn a small proportion of the nitrogen that is present in the air plus nitrogen compounds found in vehicle fuels. NO can irritate airways, especially the lungs, and also are precursors for the formation of smog components.
CO results from the incomplete combustion of vehicle fuels and its toxicity causes impaired oxygen delivery and utilization at the cellular level. CO affects several different sites within the body but has its most profound impact on the organs with the highest oxygen requirement, namely brain and heart.CO reversibly binds hemoglobin, resulting in relative functional anemia. Chronic CO exposure may present with loss of dentition, gradual-onset neuropsychiatric symptoms, or impairment of cognitive ability.
SO2 causes its irritant effects by stimulating nerves in the lining of the nose and throat and the lung’s airways. This causes a reflex cough, irritation, and a feeling of chest tightness, which may lead to narrowing of the airways.
Benzene and formaldehyde are well-recognized carcinogens.
Effects of air pollution due to automobiles on health contribute mainly to asthma, chronic obstructive pulmonary disease (COPD), emphysema and lung cancer.
Five easy pollution control methods are:
- Drive less
- Start a “No Driving Day” once a week
- Walk, cycle, take the bus or train whenever possible
- Incorporate fuel conserving measures
- Drive an electric car
Be car-free. Be care-free. Free from anxiety of a deadly health crisis caused by vehicle pollution, as the effects of the air pollution on health are hazardous and irrevocable.
