The Center for Firefighter Health Collaborative Research works with firefighters and fire departments to study the occupational health risks that firefighters face. Our research gathers data that will inform decisions, practices, and policies to keep firefighters safer and healthier.
The Center builds on years of firefighter health research conducted by Zuckerman College of Public Health faculty in close collaboration with fire departments, research that has already had a lasting positive impact on firefighter health.

Projects and Grants
The Firefighter Multicenter Cancer Cohort Study
This project is funded from 2016 through 2023. This project was federally funded by the Federal Emergency Management Agency (FEMA).
Interventions to Reduce Firefighter Cancer and Cardiovascular Risks
The goal of this research is to reduce firefighter cancer and cardiovascular disease risks, including but not limited to risks associated with PFAS exposure. This project is funded from 2023 through 2026. This project was funded by the Arizona Board of Regents.
Learn more in this video.
Per- and Polyfluoroalkyl Substances (PFAS): Firefighter Exposures and Toxicity
Exposure to per- and polyfluoroalkyl substances (PFAS) in the general population has been linked to cancer, elevated cholesterol, altered immune and endocrine response, respiratory disease, and reproductive toxicity. The goal of this project is to gather further evidence on PFAS exposure in firefighters and develop best practice recommendations to reduce firefighter PFAS exposure. This project is funded by FEMA from 2019 through 2022.
Per- and Polyfluoroalkyl substances (PFAS) Exposures and COVID-19 in Firefighters
This was funded from 2022 through 2022 by the National Institute of Environmental Health Sciences (NIEHS).

Wildland Fire Fighters: Exposure Assessment, Carcinogenic Effects and Risk Management
This project was funded by FEMA from 2021 to 2024.
- Women Firefighters
Inhaled Environmental Exposures and Anti-mullerian Hormone Levels, a Marker of Reproductive Health
Firefighters are exposed to many harmful materials and conditions while fighting fires. These hazardous exposures put them at risk for damaging health effects, including those that may negatively impact female reproductive health. Anti-müllerian hormone (AMH) can be used as a measure of ovarian reserve, or the quantity of eggs in the ovaries. We will measure the AMH levels of female firefighters and compare them to the AMH levels of females who are not firefighters. This project is receiving federal funding from 2020 through 2022.
Women Fire Fighters Study: Stress, Cancer Risk and Reproductive Toxicity
Women firefighters have high rates of post-traumatic stress disorder, increases in certain cancers, and adverse reproductive outcomes compared to women in the general population. However, the lack of sufficient information on the causes of and mechanisms leading to these occupationally related illnesses limits the creation of effective interventions. The goal of this project is to evaluate stress, cancer risk, and reproductive toxicity in women firefighters and to develop, beta test, and assess the feasibility of a peer support intervention. This project was funded by the FEMA from 2020 through 2023.
