Air Quality

Air quality is the condition of the air people breathe, both outdoors and inside buildings. It is shaped by pollution from vehicles, industry, power generation, fires, and everyday products, and it affects health, especially for children, older adults, and people with lung or heart conditions. The Environmental Protection Agency, states, and local agencies measure it and set rules.
