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.
