How Your Car Can Make the Air Cleaner

Jul 18, Particulate matter is singlehandedly responsible for up to 30, premature deaths each year. 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. Sep 04, Vehicles are Americas biggest air quality compromisers, producing about one-third of all U.S. air pollution. The smog, carbon monoxide, and other toxins emitted by vehicles are especially.

By: Meghan E. Motor vehicles emit a number of pollutants. Perhaps the most damaging is particulate matter, a combination of organic material and inorganic substances. Dust, soil, acids, metals, and organic chemicals are some of the components of particulate matter. Most of the stuff is extremely small, and the smaller contributf particle, the more damaging; particles less than 10 micrometers in diameter are capable of entering the lungs. Once in the lungs, the particulate matter can tp cause serious problems for the heart.

Nitrogen dioxide, produced when fuel is burned at high temperatures, can also spell trouble; in high concentrations, it can damage your lungs and cause chest pains. Volatile organic compounds better known as VOCs are also found in air pollution, and they're just as dangerous as the name would suggest. Unlike particulate matter and some of the other well-known pollutants, VOCs have no taste, smell or color.

They're known as "volatile" because of how easily they xars at room temperature. Some VOCs, such as benzene, are known carcinogens. Though VOCs are primarily produced through industrial means, vehicles do release them as they burn fuel. Even car interiors release VOCs. But just how cnotribute pollution do cars produce? The answer is more complicated than you might expect. For starters, air pollution isn't consistent around the world or even around the country. Areas of dense populations -- or, more specifically, areas where large quantities of fossil fuels are burned -- have much higher levels of air pollution than sparsely-occupied regions.

Heavily-populated cities such as Los Angeles, Mexico City and Beijing are all famous for their air pollution. Weather conditions also impact air quality, resulting in daily fluctuations in the cads of the air. So, pollution levels howw just vary from one geographic area to another; they also vary from one day to the next. And yet with all those variables, scientists can still give us an approximate percentage of the air pollution produced by cars in the United States.

According to the Environmental Protection Agency, motor vehicles produce roughly contributte of pollutants like VOCs, nitrogen oxide and particulate matter. Seventy-five percent of carbon ocntribute emissions come from automobiles. In urban areas, harmful automotive emissions are responsible for anywhere between 50 and 90 percent of air pollution.

All told, that's quite pollutiion lot of air pollution coming from our vehicles. Because many people are reluctant to give up their cars or reduce the number of time spent on the road, the automotive industry has made some key changes over the years that help reduce the harmful emissions produced by vehicles.

Catalytic converters were developed in the s as a way to convert pollutants into emissions that aren't quite so harmful. More recently, hybrid and electric vehicles have become extremely popular among the environmentally-minded. But even with these advancements, air pollution remains a major concern. As the debate over the environment and the risks of fossil aur continues, motor vehicles still represent a major challenge on the road to clean air.

Production and Destruction

Dec 07, And yet with all those variables, scientists can still give us an approximate percentage of the air pollution produced by cars in the United States. According to the Environmental Protection Agency, motor vehicles produce roughly one-half of pollutants like VOCs, nitrogen oxide and particulate matter. Seventy-five percent of carbon monoxide emissions come from automobiles. In Author: Meghan E. Smith. AIR POLLUTION IS CAUSED BY MULTIPLE SOURCES, including gasoline and diesel vehicles, and industries that burn carbon fuel. All of these emit nitrogen oxides . Mar 13, Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.

Cars can convey a sense of freedom and movement, not to mention style and status. But they also can have a big impact on the planet. Here's a few key areas to consider. Cars consume a lot of energy before they ever make it to the open road. Automotive production leaves a giant footprint because materials like steel, rubber, glass, plastics, paints, and many more must be created before a new ride is ready to roll. Plastics, toxic battery acids, and other products may stay in the environment.

Fortunately, junkyard pile-ups are becoming much smaller than they were in the past. Production, recycling, and disposal costs to the environment are difficult to quantify and largely beyond the control of most consumers. It's also true that most of an automobile's environmental impact, perhaps 80 to 90 percent, will be due to fuel consumption and emissions of air pollution and greenhouse gases that climate scientists say are driving global warming.

Fortunately, the level of that impact is very much under the control of the driver. Petroleum products raise environmental red flags even before they are burned. Extracting them from the earth is an energy-intensive process that can damage local ecosystems. Shipping fuels can also consume a lot of energy, and creates an occasional environmental disaster such as an oil spill.

As world demand rises, and unconventional fuel sources, such as oil sands , become more economically viable, the ecological impacts of petroleum extraction might also increase dramatically. It's also partly why electric-powered vehicles can help reduce environmental impacts, because they don't burn fossil fuels. The smog, carbon monoxide, and other toxins emitted by vehicles are especially troubling because they leave tailpipes at street level, where humans breathe the polluted air directly into their lungs.

That can make auto emissions an even more immediate health concern than toxins emitted high in the sky by industrial smokestacks. Also difficult to quantify, another associated impact of cars is the building of roads to support them, as well as the urban sprawl that tends to follow in their wake. This issue can be difficult to tease out of other factors, such as population growth and resource consumption, but it is also not easily addressed by technological advancements like fuel efficiency and electric propulsion.
