This webinar includes a presentation on wildland fire smoke which impacts millions of people in the U.S. every year. While the negative impacts of PM2.5 on air quality and human health are well established, wildland fires mobilize other pollutants that impact EPA’s mission areas of clean air and clean water, with implications for human health. This webinar discusses a wide range of effects of wildland fire on air and water quality, including emerging science on the topic (e.g., pollutants mobilized through the burning of human infrastructure). Finally, the webinar discusses how this research can inform public communications on the risks of wildland fire and approaches to mitigate those risks.
