A fleet of vehicles will have far reaching impacts; perhaps best known by the general public is the impact on air quality.
Air pollutants may be released in a number of ways: first through evaporation during fueling, second through tailpipe emissions while a car is running, and third through chemical reactions occurring with byproducts or unused components emitted into the atmosphere.(Motor vehicles and toxic air pollutants. 2008) Typical chemicals released include benzene, toluene, xylenes, diesel particulate matter, and volatile organic compounds.(Motor vehicles and toxic air pollutants. 2008) In addition, formaldehyde and acetaldehyde may be produced in reactions with the air.

According to a 2005 study, air pollution may be estimated to be responsible for 3% of adult cardiopulmonary disease mortality; 5% of trachea and bronchus mortality; and in children 1% of mortality from acute respiratory infections in urban areas throughout the world.(Cohen et al., 2005)
Air pollutants from a fleet of vehicles may also cause environmental impacts such as the creation of ground level ozone, a key component of smog, and the emission of greenhouse gases suspected of causing drastic changes in the earth’s climate. (Transportation and air quality planning: Federal laws provide tools for change. 2008)
To combat these threats, federal and state level policies have been put in place to help monitor and reduce air pollution. Perhaps the most far reaching of these was the 1990 Clean Air Act which required the reformulating of gasoline and set emission standards from hydrocarbons and diesel particulate matter. Subsequent amendments to this act required the removal of lead from gasoline and limitations to the amount of sulfur in diesel fuel. (Air toxics from motor vehicles. August 1994) Government regulations on vehicles added requirements for emission reduction equipment such as catalytic converters.(Motor vehicles and toxic air pollutants.2008) Specific federal government
Air is natural resource that everyone uses and abuses. Everyone wants their vehicle on the road and when that happens air pollution, carbon emission and greenhouse gases from many of them are emitted into the air which will vastly destroy this precious and commonly use resource.
The burning of gasoline by automobiles releases carbon dioxide and other types of air pollution
Cars consist of being the number one way of travel throughout the United States. We rely on them to transport us to work, activities and necessary destinations. With this constant use of vehicles, it has had a negative impact on the environment. Although cars were invented almost a century ago to make life easier with getting around, car pollution has been our number one source of air pollution and has significantly impacted our environment due to how accessible they are. Arising problems such as air pollution, global warming, and health issues of americans, we have to come to the understanding that our environment is at risk if the amount of car pollution continues to increase.
In Mexico the majority of the population is exposed daily to fames produced by 3.6 million vehicles. The worst time of air pollution in Mexico is near the end if
The large majority of todays cars and trucks travel by using internal combustion engines that burn fossil fuels and gasoline. A variety of emissions are polluted into the atmosphere when burning gasoline to power cars and trucks. Emissions that are released directly from cars and trucks into the atmosphere are the primary cause of car pollution but it still causes pollution the air during the manufacturing and refueling processes. Primary pollution from motor vehicles is pollution that is emitted directly into the atmosphere where as secondary pollution is caused from chemical reactions between pollutants after they have been released into the air at least 92 million Americans still live in areas with chronic smog problems. The U.S. Environmental Protection Agency predicts that by 2010, even with pollution controls more than 93 million people will live in areas that violate health standards for ozone (urban smog) and more than 55 million Americans will suffer from hazardous levels of fine particle pollution, which is especially dangerous to children and senior citizens.
Over time vehicles have become a gigantic cause of pollution and global warming. As years have passed by vehicles have been designed to be environmentally friendly. This is only happening for the vehicles that are everyday vehicles. Most of those vehicles are still not fully efficient due to the inability of affording a new car. Racing in the biggest thing that is in need of finding a way to limit it to release less pollution.
Increase in motor vehicles use and increase exposure to traffic emissions has been linked to adverse health effects such as asthma exacerbation, decrease pulmonary function, adverse health outcomes, and childhood cancer. 2 In urban areas, motor vehicles contribute to more than 50 % of the air pollution. 2
Transportation is the largest source of air pollution in the United States. Air pollution kills globally more than any diseases. In 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air. We can reduce transportation, air pollution is different ways. By keeping our vehicle in well-tuned and tires inflated properly to reduce exhaust emissions. Also, avoid idling because it contains more pollute and combines errand into one trip. Air pollution can directly cause respiratory disease or exacerbate existing conditions in susceptible populations, such as children or the elderly and animal.
Pollutants that are given off through the emissions of automobiles are hydrocarbons, nitrogen oxides, carbon monoxides, and carbon dioxides. Hydrocarbons emitted by automobiles create smog. Smog can create health problems for people. These problems include lung and respiratory problems. Nitrogen oxides form acid rain that hurts plants, wildlife, and the paint on our cars. Carbon monoxide reduces the flow of oxygen in the bloodstream. Carbon dioxide is a "greenhouse gas" and is a primary factor contributing to global warming.
“Automobiles have a large impact on the quality of our environment and public health. Automobile use affects virtually every aspect of environmental quality - including noise levels, air quality, water pollution, and urban sprawl. Ninety percent of the environmental impact of automobiles occurs through the operation of the cars: about 10 percent from the production, raw materials and disposal of
The amount of factories and industries has grown immensely through the previous years which has resulted in an expansion in the consumption of petroleum products. Innovation has begun to increase and has promoted the expansion of the production of cars. As stated by the Air Quality Research Center, “Air pollution is one of the most dangerous environmental problems, causing many adverse health effects and responsible for 50,000 deaths in the U.S. each year” (Air Pollution and Health – Air Quality Research Center.). The smog and
Other pollutant from cars was lead; it is highly toxic metal. Lead has been phased out of gasoline, but there, are other sources of it. It includes paints, production of lead batteries, water pipes, and a few heir dye products. Car exhausts can also produce nitrogen oxide, volatile organic compounds, which are also, product of burning fuels. Factories and power plants produce same pollutants as cars do, but they produce them in bigger mnozstve and the produce some more such as sulfur dioxide, which is made during production of paper, burning coal in power plants, or smelting of metal. Burning other fuels like wood, or natural gas can make all of these pollutants too.
In this research paper I will explore the effect on the environment of the anthropogenic emissions of greenhouse gases emitted by modes of transportation. My first angle will expose how automobiles release harmful toxins. My second angle will reveal how the running of trains has a negative impact on the environment. My third angle will disclose how the flying of airplanes has a detrimental effect.
Every year passenger vehicles contribute a large portion of the carbon monoxide and nitrogen oxides in our air, although there are laws and regulations set to help reduce these pollutants I believe stricter laws and regulations should be enacted to further reduce green house gas emissions produced by vehicles in order to protect our environment and slow the process of global warming.
In fast-paced growing and developing countries, outdoor air pollution poses a serious problem. The population is highly reliant on motor vehicles for efficient and affordable transportation,
