Air pollution caused by cars
is one of the more challenging forces that air pollution environmentalists are dealing with.The air pollution from cars is caused, in significant part, by fuel emissions. This is a very familiar term although few of us can tell out friends and neighbors what it means. A fuel emission is a particle of the same fuel that you put into your car when you hit the petrol station.This fuel particle has gone through the combustion process without burning in its entirety. Releasing this particle into the air contributes to the air pollution caused by cars.

Effects of Car Pollution
Cars are the greatest contributing agent of pollution in most cities across the globe. Emissions from car exhaust contain a range of toxic substances. They include carbon monoxide, nitrogen dioxide, hydrocarbons lead and tiny suspended particles. These chemicals are hazardous to human health. The emissions also have a serious impact on the environment.





*Greenhouse Effect and Global Warming


The greenhouse effect is increased by the release of certain gases like carbon dioxide and nitrous oxide emitted by cars into the atmosphere.This results in more heat being trapped near the planet, thereby making the planet warmer
*Ozone Layer Depletion





it absorbs harmful ultraviolet radiation (a major cause of skin cancer), protecting the planet's surface from exposure. Air pollutants mostly caused by car emissions

*Respiratory Diseases

Car exhaust emissions aggravate existing heart or lung diseases, such as asthma, chronic obstructive pulmonary disease, congestive heart disease and ischemic heart disease.Particle pollution affects children and the elderly, often causing coughing and shortness of breath.







Prevent Air Pollution


*used hybrid powertrains.  which is environmental friendly cars


Hybrid cars are, of course, playing a large part in the current era of the green transportation revolution. In the past decade, they've gone from avant-garde curiosities to mainstream objects seen in parking lots everywhere. Most people associate the term "hybrid" with better gas mileage and lower emissions


*The bicycle is the best alternative of all

*Consider alternative means of transportation, such as walking
Walking can provide the same benefits as a running program. General health benefits are aquired from any walking. For cardio benefits the key is walking fast enough to get your heart rate up. Walkers may miss fewer days due to injury than runners while achieving similar improvements in aerobic conditioning.
