Air quality affects public health, the environment, and our quality of
life. Air pollution causes lung disease, makes existing heart and lung
disease worse, and is associated with cancer.
The Air Quality Program's goal is to safeguard public health and the environment by preventing and reducing air pollution. Washington's main sources of air pollution are
