Extended exposure can lead to irritation of the eyes and respiratory system and even death. Primary pollutants are molecules that are directly emitted into the atmosphere (Morton, B. Essen. Wrkbk.). Transportation, a common producer of primary pollutants, is proportionally the reason why large cities, such as Milan (Italy), Mexico City (Mexico) and Linfen (China), experience a haze during the day (http: (2)). In a car’s internal combustion chamber reactions taking place create energy.
Harmful Aspects of The Automobile Air pollution refers to the presence of foreign substances in the atmosphere. Air pollution is a problem in countries where urban and population growth have been accompanied by the use of the automobile. Smog, carbon monoxide, and acid rain, are only a few of these foreign substances in the atmosphere. The negative effects these poisons have upon the environment and the human body are astronomical. Respiratory inflammation, impaired vision, learning disabilities, and death are all results that smog, carbon monoxide, and acid rain have on the human body.

EPA (2013) has a record of 187 hazardous air pollutants which include contaminants such as benzene in gasoline, perchlorethlyene released from some dry cleaning companies and methylene chloride used for production of solvent and paint stripers. EPA (2013) stated that there are six common pollutants which are also called criteria pollutants. These include Ozone, Particulate matter, Carbon monoxide, Nitrogen oxide, Sulfur dioxide and lead. The Union of Concerned Scientists (2013) proposed that transportation is the highest cause of air pollution in the United States. These automobiles serve as a direct source of air pollution to the environment and also produce precursor substances that forms some secondary contaminants (EPA, 2014).
Acid rain destroys the outsides of buildings, statues, etc. Acid rain can also contaminate drinking water, damage vegetation, and destroy sealife. These two pollutants are two of the most dangerous pollutants released through car exhaust. If these two pollutants were cut down just a little bit our planet would be a safer place to live. Carbon dioxide is another gas released through exhaust emissions.
In this paper I will concentrate on the most common types of pollution: air pollution and water pollution. Air Pollution Air pollution is the most harmful type of pollution. It occurs because of the use of burning fuel that is necessary for transportation, which is an important activity of people’s daily lives. We need cars to go to work, planes to travel, and ships to deliver goods. The burning of fuel resulting from these activities causes air pollution.

The first thing I will discuss is major air pollutants. Transport is the major source of air pollution because of its heavy dependence upon the combustion of fossil fuels, either in vehicles or at power stations. The major air pollutants are carbon dioxide, carbon monoxide, nitrogen monoxide, nitrogen oxides, hydrocarbons, sulfur oxides, lead, and suspended particulate matter. The most serious environmental issue pertaining to urban areas is that of air quality. The principal sources of air pollution in urban areas are derived from the combustion of fossil fuels for domestic heating, for power generation, in motor vehicles, in industrial processes and in the disposal of solid wastes by incineration.
It is important to define greenhouse gases and describe which gases are emitted from light-duty trucks and SUV’s. According to the EPA’s Global Warming Website on emissions¹, some greenhouse gases are naturally occurring, such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Some unnaturally occurring greenhouse gases include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which come from other industrial processes(1). All of these gases are capable of absorbing heat from the earth’s atmosphere, but some gases have a much greater propensity to trap heat in the atmosphere than others, result... ... middle of paper ... ...ov/oar/globalwarming.nsf/content/climate.html5. 5U.S.
There are at least 1000 different chemical created each year, out of all existing chemicals, 60,000 alone were created in the United States and this dependency on chemicals by the industrial society creates many problems. According to U.S. Environment Protection Agency [U.S. EPA], 35,000 types of all existing chemicals are considered hazardous to human health and the environment (as cited in Shah, 2000). Hazardous wastes are materials that consist of chemical constituents which can easily harm the environment, exposing human and other living things to diseases or even death if it is incorrectly used or managed (U.S. EPA, 2011). Hazardous wastes, which contain dangerous compositions, can exist in many different forms such as liquids, solids, gaseous or slush.
