The Pollution Placed In The Air From Motor Vehicles Every Year

Numerous pollutants result from motor vehicles. The most damaging is the combination of inorganic and organic substances. This includes soil, dust, metals, acids and organic chemicals. This is mainly small particles, and unfortunately these cause the most damage’. A particle smaller than 10 micrometers can enter the lungs. These particles can jeopardize the heart once they have reached the lungs. Nitrogen dioxide is produced from the high temperature of the fuel, and high enough concentrations can cause chest pains and lung damage.

Many individuals question the amount of pollution produced by cars, and the answer is complicated. Air pollution is not a consistent factor around the globe, and the levels of pollution dramatically increase in areas where a substantial amount of fossil fuel is burned. Cities including Mexico City and Los Angeles have a reputation for air pollution, while there is very little in sparsely populated areas. Daily fluctuations are impacted by the weather, so the pollution level changes not only according to the area, but on a day to day basis.

Despite these variables, scientists have estimated the amount of air pollution resulting from vehicles within the United States. The Environmental Protection Agency has stated approximately half of all pollutants including particulate matter, nitrogen oxide and VOC’s is the result of automobiles. The harmful emissions in urban areas cause fifty to ninety percent of all air pollution.

Due to the numerous individuals who will not limit their driving or give up their cars, there have been important changes made by the automotive industry to reduce harmful emissions. During the 1970’s the development of catalytic converters converted pollutants into less harmful emissions. The current production of electric and hybrid vehicles has become very popular with individuals conscious of the environment. Despite these advancements, air pollution is still a major concern. Burning fossil fuel is a detriment to clean air.
