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 definition of disadvantaged communities, smoke exposure appeared equitable. Another measure, including racial and ethnic identity data, showed inequitable exposure.
•[05:26] Casey explores possible reasons for this inequitable exposure.
•[06:21] The benefits of improved air monitoring among marginalized communities.
•[07:34] Caveats and limitations of the study.
•[08:35] Next steps in this line of research.
•[09:27] Hopes for policy impacts.
•[10:22] Conclusion.

Tune into PNAS Science Sessions for a direct line to the people shaping modern science. Produced by PNAS, this podcast offers more than just summaries of published research; it’s where you hear the candid, often personal stories behind the headlines. Each episode features concise conversations with the researchers themselves-from emerging voices to established Academy members-alongside the policymakers whose decisions are informed by this work. You’ll get a genuine sense of the questions that drive these experts, the unexpected hurdles they face in their labs and field studies, and why their findings matter right now. The scope is deliberately wide, reflecting the interdisciplinary nature of science itself, covering discoveries that range from microscopic processes to planetary-scale phenomena. This isn't about dry lectures, but about capturing the human endeavor of investigation. For anyone curious about how science actually unfolds and wants to understand the context of breakthroughs as they happen, this podcast serves as an essential, engaging resource. It connects the dots between a published paper in a prestigious journal and the real-world implications that ripple out from it.
