Air Quality
The quality of the air we breathe can affect our health. Air pollution is made up of gases, liquids, and particles that can be harmful to humans and the environment. Pollutants come from a wide range of sources, including vehicle exhaust, industrial processes, energy generation, home and building heating, wood burning, and construction dust. Most of the air pollution we live with on a day-to-day basis is created by vehicle exhaust and industrial emissions. Several sources of air pollution also generate greenhouse gases that contribute to climate change.
Smog, the grey-brown haze that sometimes occurs on hot days, is a term to describe air pollution. It is formed when air pollution mixes with dust, sunlight, and heat.
