The continuing worldwide challenge
Despite decades of variant efforts by governments worldwide, air pollution is still considered the main challenge, with air quality that is in continuing decline over the past few years in many countries.
Health & Economic consequences
Union of concerned scientists highlighted that air pollution / poor air quality increases respiratory ailments like asthma and bronchitis, it also heightens the risk of life-threatening conditions like cancer and up to 30K premature death annually, with a burden on health care system & substantial medical costs.
The key contributors to Air pollution
“Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.” As described shortly by NASA Climate Kids
Vehicles contribution to Air pollution
“Passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. 1.1In 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.” As stated by Union of concerned scientists
Causes of vehicle’s emissions
Deposits that deteriorate the air / fuel flowthrough the engine
