Project at a Glance

Title: Examining the Health Impacts of Short-Term Repeated Exposure to Wildfire Smoke

Principal Investigator / Author(s): Wu, Jun

Contractor: UC Irvine

Contract Number: 21RD003


Research Program Area: Health & Exposure

Topic Areas: Health Effects of Air Pollution


Research Summary:

Given the hotter and drier weather in California and the impacts of climate change, longer term and larger wildfires are expected to continue and a project that updates the estimates of health impacts of exposure to wildfires in California is needed. The University of California, Irvine (UCI) has assembled a multi-disciplinary team with expertise in community air quality modeling, remote sensing and air pollution exposure assessment, air pollution epidemiology, biostatistics, and risk communication to expand the understanding of wildfire-induced health impacts. This study will link detailed health and covariates data with high spatiotemporal resolution wildfire smoke exposure obtained from sophisticated air quality modeling to examine the impacts of wildfire on a number of health outcomes, including cardiovascular, respiratory, birth, and mental health impacts throughout the state. In addition, this study will address concerns for disadvantaged communities (DAC) through collaborative and informative outreaches with designated community members in California. The results of this project will better inform CARB's analysis of the health burdens from extreme events like wildfires by providing a dose response assessment of wildfire smoke. CARB has been developing programs and policies to reduce and provide solutions to worsening climate change impacts, including those in natural and working lands, and the results of this study will help CARB in the analysis of the potential health benefits of policies that help to reduce the risk of wildfire. Moreover, this project would inform messaging and outreach efforts designed to help the public better understand the impacts of smoke and how to protect themselves from it, specifically in DAC that are most vulnerable to climate change impacts.
