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. Additional emissions are associated with refining and distribution of fuels and to a lesser extent, manufacturing and disposal of the vehicle.
Pollution is now a common place term, that our ears are attuned to. We hear about the various forms of pollution and read about it through the mass media. Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside.
A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. It occurs when any harmful gases, dust, smoke enters into the atmosphere and makes it difficult for plants, animals and humans to survive as the air becomes dirty.
Air pollution can further be classified into two sections- Visible air pollution and invisible air pollution. Another way of looking at Air pollution could be any substance that holds the potential to hinder the atmosphere or the well being of the living beings surviving in it.
The sustainment of all things living is due to a combination of gases that collectively form the atmosphere; the imbalance caused by the increase or decrease of the percentage of these gases can be harmful for survival. Read here more about 40 facts of air pollution.
The Ozone layer considered crucial for the existence of the ecosystems on the planet is depleting due to increased pollution. Global warminga direct result of the increased imbalance of gases in the atmosphere has come to be known as the biggest threat and challenge that the contemporary world has to overcome in a bid for survival.
Types of Pollutants In order to understand the causes of Air pollution, several divisions can be made. Primarily air pollutants can be caused by primary sources or secondary sources. The pollutants that are a direct result of the process can be called primary pollutants.
A classic example of a primary pollutant would be the sulfur-dioxide emitted from factories Secondary pollutants are the ones that are caused by the inter mingling and reactions of primary pollutants. Smog created by the interactions of several primary pollutants is known to be as secondary pollutant.
Causes of Air pollution 1. Burning of Fossil Fuels: Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles is one the major cause of air pollution.
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.
Carbon Monooxide caused by improper or incomplete combustion and generally emitted from vehicles is another major pollutant along with Nitrogen Oxides, that is produced from both natural and man made processes.Passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution.
In , transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.
The Problem—Increasing Air Pollution in Cities in the mid's. After World War II, economic growth, population growth, rapid suburbanization, and the closing of some public transit systems led to more reliance on personal vehicles for transportation.
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. Air pollution accounts for about 6 percent of deaths each year in Austria, France, and Switzerland, according to a study published in the Lancet medical journal.
The study found that half of the those deaths can be attributed to pollution from vehicles. Air pollution is caused by a wide variety of things.
The earth is great at cleaning the air on its own. However, air pollution has grown so much, the earth can no longer clean all of it. This is starting to have adverse effects on the environment such as causing acid rain, smog and a . 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. The U.S. government has imposed tougher emissions standards, and .
