Keeping track of the current air quality information is especially important for people who are sensitive to air pollution, including young children, people with asthma and other lung diseases, and the elderly. Carbon monoxide emissions are a result of incomplete fuel combustion. CO is a colorless, odorless gas which limits the blood's ability to transport oxygen to body tissues. This places a strain on people with weak hearts and respiratory diseases, the elderly, and pregnant women. High levels of CO can also cause dizziness, headaches, impaired coordination and, at very high levels, even death.
Nitrogen oxides are the result of high temperature combustion.
These pollutants can damage lung tissue and aggravate chronic lung diseases such as asthma. In addition, NOx can lower the body's resistance to respiratory infection. Ozone, a major component of smog, is a strong irritant to the eyes and respiratory tract. Like NOx, ozone can cause increased respiratory problems for people with asthma and other respiratory diseases. Schedule a regular tune up for your car.
