Cars cause air pollution

Studies have linked pollutants from vehicle exhaust to adverse impacts on nearly every organ system in the body. While this air pollution carries significant risks for human health and the environment, through clean vehicle and fuel technologieswe can significantly reduce emissions from our cars and trucks, while cutting projected U. The ingredients of air pollution Cars, trucks and buses produce air pollution throughout their life cycle, including pollution emitted during vehicle operation and fuel production.

Cars cause air pollution

When cars burn gasoline, they emit pollutants. Gasoline fumes escape into the air even when we pump gasoline into our fuel tanks.

There are four major pollutants that come from cars: A car emits carbon monoxide when the carbon in fuel doesn't burn completely. A car's exhaust emits hydrocarbons, a toxic compound of hydrogen and carbon.

When fuel burns, nitrogen and oxygen react with each other and form nitrogen oxides NOx. Pollutants from cars contribute to various types of air pollution. When hydrocarbons and NOx combine in sunlight, they produce ozone.

Cars cause air pollution

When holes in the atmosphere's ozone layer allows ozone to come closer to Earth, it contributes to smog and causes respiratory problems. Air pollutants emitted from cars are believed to cause cancer and contribute to such problems as asthma, heart disease, birth defects and eye irritation.

Cars cause air pollution

Emissions from cars increase the levels of carbon dioxide and other greenhouse gases in the atmosphere. That said, many scientists believe that burning fossil fuels such as gasoline causes greenhouse gas levels to spike, leading to global warming.

This makes sense, because many other human activities contribute to air pollution as well. In fact, the production of electricity by coal-fired power plants and other sources can cause more pollution than most cars. If that wasn't enough, we pollute the air when we heat our homes and public buildings with fuels other than electricity -- just as we do when we drive our cars.

Big trucks, bulldozers, ships and boats, trains and even snowblowers pollute the air. According to the EPA, motor vehicles collectively cause 75 percent of carbon monoxide pollution in the U.

The percentage of air pollution caused by cars is higher in urban areas and higher still near major highways. Fortunately, better fuels and new technologies in cars help.

Hybrid cars, electric cars and alternative fuels will continue to help, but the sheer number of people -- and cars -- on the roads offset those improvements.

People can help by driving less. If you have to get out of the house, combine trips for efficiency. Walk, bike, carpool or use public transportation if you can.Cars emit greenhouse gasses, such as carbon dioxide, which contribute to global warming. (See Reference 2, page 13) Some air pollutants and particulate matter from cars can be deposited on soil and surface waters where they enter the food chain; these substances can affect the reproductive, respiratory, immune and neurological systems of animals.

Pollution emitting from vehicles including trucks, jeeps, cars, trains, airplanes cause immense amount of pollution. We rely on them to fulfill our daily basic needs of transportation.

But, there overuse is killing our environment as dangerous gases are polluting the environment. What causes air pollution? Air pollution can result from both human and natural actions. Natural events that pollute the air include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds and natural radioactivity.

Cars, trucks, jet airplanes and other combustion engine vehicles cause air pollution. The exhaust from these contains carbon monoxide, nitrous oxide and gaseous oxide.

This type of air pollution creates smog (as seen in Los Angeles) which causes respiratory health problems and holes in the ozone layer, which increases the exposure to the sun's.

Transportation is a major source of air pollution in the United States.

Types of Pollutants It is emissions of these pollutants that are regulated by the Euro emissions standards. Modern cars, if kept in good condition, produce only quite small quantities of the air quality pollutants, but the emissions from large numbers of cars add to a significant air quality problem.
