Take a deep breath. Ahhh. Fresh, clean air. Or is it?

Depending on where you live, there's a chance you inhaled some form of air pollution. It could have been from a factory in your community, but cars, lawn mowers, and even some paints and cleaning solvents can contribute to poor air quality.

Often you can't see or smell or taste air pollution until it gets really bad, but it can still cause significant health problems. So how do you find out if it's there?
