Notes
A University of Washington thesis presentation by Mariah Dittmore examining the short-term cardiorespiratory health effects of exposure to aircraft-related ultrafine pollution in communities. The research builds on previous studies showing increased inflammatory markers from aircraft pollution exposure.
