The environmental impact of cars

Cars, trucks, and other vehicles operated by fossil fuel are significant contributors to air pollution. It arises through the evaporative emissions from the fueling system of volatile organic compounds such as hydrocarbons and from other chemical components that leave the engine through the crankcase. Experts prove that transportation emits 75℅ nitrogen oxides in our air and is a significant source of global warming. The pollutants released through vehicle's exhaust have on nearly every organ system in the human body and other species.

Greenhouse gases trap heat in the atmosphere, which directly raises the temperature all over the world. The burning excess number of fuels has increased 1 degree F in the global climate, and the worst part is that the temperature will continue to rise over the coming decades. Global warming directly affects sea level, farming, wildlife, natural landscape, and health.

Bad air quality raises a significant risk for human health and the environment. However, through clean vehicles and updated fuel technologies, we can reduce the carbon emission from our cars to help transform transportation sectors.

Emission from heavy-duty vehicle

From carrying goods from manufacturers to the stores delivering essentials\packages/mails to picking up our trash trucks and buses play a vital role in making our everyday life convenient. Public transport and personal vehicles are transporting thousands of people around cities every day. As much as cars make our life easier, it has also affected public health and global warming. Heavy-duty vehicles cover-up space of only 5-6℅ of all vehicles on the road. Still, they generate more than 25℅ of global warming emissions contributed through transportation sectors.

The ingredients of air pollution

Car, buses, and trucks release harmful pollutants into the environment throughout their life cycle, including emissions during driving operating and fuel production. Additional emissions are associated with the manufacturing and disposal of the material being used.

The air pollution released through cars is divided into primary and secondary pollution. The pollutants are directly released into the environment. While the secondary results from the chemical reactions between pollutants in the air. People with lower immune chronic illness are especially susceptible and highly vulnerable to the hazardous effects of bad air quality. These are some of the significant pollutants released through motor vehicles-

Particulate matter- 

These particles are seen in the vehicle's exhaust which poses a severe threat to human health as they can penetrate deep into the lungs. Diesel exhaust is a significant contributor to PM pollution.

2.     Volatile Organic Compound- 

The pollutants form ground ozone after reacting with nitrogen oxides in the presence of sunlight. It is the main ingredient in smog, which is very common in metropolitan cities nowadays and causes invisibility and irritation to the lungs.

Nitrogen Oxides- 

It weakens the body's metabolism to combat respiratory infections such as pneumonia and influenza.

Carbon monoxide- 

It is formed by Fossil fuels released from cars and trucks. It can block oxygen from the brain, heart, and other significant organs upon inhalation.

However, we as citizens can take preventive steps to reduce the carbon footprint. Getting your vehicle emission test done via mobile emission testing stations will save us in many ways. It will help us save nonrenewable resources, making our environment free of pollution, and saving endangered species. So, take a step today and save the only planet you have.
