Air Quality

Historically, "good" or "bad" air quality was determined by measuring how much pollution was in the air. The Environmental Protection Agency tracks the emission of six criteria pollutants and uses those measurements to determine the quality of air throughout the nation. The criteria pollutants are: carbon monoxide, lead, nitrogen oxides, particulate matter, sulfur dioxide, and volatile organic compounds. During the 1990s much was done to reduce the amount of criteria pollutants in every state. But recently, EPA has identified two other sets of pollutants that have taken front stage; particulate matter 2.5 and ground-level ozone. At this time most of the 95 largest urban areas in the United States do not meet federally mandated standards for those two pollutants. PM 2.5 refers to particles that are smaller in diameter than a single strand of human hair. These particles enter the lungs, never to leave. Individuals with asthma, heart disease or chronic lung diseases are especially at risk during days when the pollution level in their community is high. How much air pollution does one average car produce? Each year, the average car causes over 600 pounds of air pollution. When vehicles are not properly maintained they get poor gas mileage and you spend more money on gas. For example, under-inflation shortens the life of a tire and decreases gas mileage. If your tires are 12 pounds per square inch (psi) below the proper level, this can result in an increase of fuel consumption of five percent. Here are a few money-saving, maintenance tips for air quality: Change your oil and oil filter regularly Keep your tire pressure and alignment correct Change your fuel filter and air filter Monitor hoses, wiring, and belts Have your vehicle tuned up regularly If warning lights come on, find out why and fix the     problem Be sure to check your owner's manual for service intervals and follow the automobile manufacturer's service recommendations.
