Asthma

EPA's coordinated approach on asthma promotes scientific understanding of environmental asthma triggers and ways to manage asthma in community settings through research, education and outreach.

In particular, there are many pollutants found indoors that can trigger asthma attacks. Learn more about indoor air quality.
