Pnas Science Sessions

Inequitable wildfire smoke exposure in California Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us. In this episode, Joan Casey shows that some California communities are disproportionately exposed to wildfire air pollution. In this episode, we cover: •[00:00] Introduction •[01:04] Joan Casey, an environmental epidemiologist at the University of Washington, describes recent decades of wildfire in California. •[01:34] Casey describes the environmental equity issues of fine particulate matter (PM2.5) air pollution. •[02:26] Casey describes why she chose to study the equity of wildfire smoke pollution exposure. •[03:01] She explains the results of the study, showing that by one defini
