Some years of progress toward cleaner air are being erased by wildfire smoke
Defying the U.S. Environmental Particle Exposure Inequality: A Case Study on the Clean Air Act of 1970-2000
The bipartisan Clean Air Act, signed into law in 1970, has had remarkable success cleaning up the nation’s air. In its first few decades, levels of the six major pollutants it addressed dropped by more than 40%. Since 2000, the drop has continued nearly everywhere in the country.

Preventing lung cancer by removing fumes from the U.S. Forest Service: Evidence from Montanans exposed to extremely high doses of smoke
The long-held policy of the U.S. Forest Service and other agencies was to suppression of fires. The Indigenous communities of the Western U.S. often used fire to keep their habitat open after frequent burns cleared away excess fuel. Now forests are packed with many more trees.
Migliaccio led a study that followed Montanans exposed to extremely high doses of smoke for 49 straight days in 2017. It found their lung function was depressed for at least two years afterward.
The Clean Air Act effectively regulates point-source pollution, like soot from power plants. It is less effective at protecting people from the risks that arise from smoke than it is from the fires.
It is possible for people to take steps to protect themselves from smoke exposure. Installing air filters in your home — and keeping them clean — can go a long way. If you have to go outside and work out in smoky air, Health experts recommend that you wear N95 or KN95 masks.

A new study by the US Environmental Protection Agency (EPA) showed that the amount of air pollution caused due to wildfires in the US is about the same as it would have been without the Clean Air Act. As per the study, wildfires cause “uncontrollable air pollution events in the US due to wildland fires”.
