Facts of car pollution

Posted by Jeff Collins on May 23, 2011 0 Comments

 Overview   According to Yale University, there are 246 million vehicles in the United States alone, making them a potent polluting force. The amount of greenhouse and poisonous gases released into the atmosphere endangers the environment and causes severe health effects in humans.

 Common Air Pollutants: Carbon dioxide and carbon monoxide are the primary air pollutants produced by a car. Carbon dioxide is a greenhouse gas that keeps solar radiation trapped within the atmosphere. Carbon monoxide is a poisonous gas that can lead to health problems, because it prevents blood from carrying oxygen to vital organs of the body.

Transportation Industry: The U.S. Energy Information Administration, the Washington Post reported, found that, after electric power generation, transportation was the largest source of carbon dioxide emissions by direct fuel use, far exceeding industrial, residential and commercial uses. In the United States cars represent approximately 89 percent of the trips made by vehicle, accounting for the largest bulk of pollution.

Pollution Rates:Cars release approximately 333 million tons of carbon dioxide into the atmosphere annually, which is 20 percent of the world's total, according to the Environmental Defense Fund. Motor vehicles also contribute 72 percent of the nitrogen oxides and 52 percent of reactive hydrocarbons. Hydrogen on Demand Generators can reduce engine's carbon foot print by as much as 70%.

Health: The American Lung Association reports that 30,000 people are killed by car emissions annually in the United States alone. Air pollution also causes numerous respiratory and cardiovascular problems and may exacerbate pre-existing conditions such as asthma. More than half of Americans live in areas that fail to meet federal air quality standards at least several days each year.
