Issues Some of the issues are that there are way to many factories polluting the air with the excess gasses they let out of the buildings. Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.

Polluted Areas in the U.S Though overall air pollution is down compared to previous years, the problem is still widespread. Visalia and Fresno, two mid-size towns in central California ranked high for short-term and year-round particle pollution. Birmingham, Ala., and Cincinnati were listed in the top 10 of metro areas with unhealthy levels of year-round particle pollution. In the Southwest, the Houston, Dallas and Phoenix metro areas had high ozone levels.VisaliaFresno Birmingham, Ala.CincinnatiHouston
