Assessing effectiveness of PFAS exposure control in exposed communities and firefighters

The aim of our project is to investigate the changes over time in PFAS concentrations in the blood serum of individuals who are known to have elevated exposures to PFAS. Individuals from exposed communities in Williamtown, Oakey and Katherine and from exposed occupational groups such as firefighters who have previously had their blood collected and analysed for PFAS and have elevated PFAS concentrations in their blood serum are invited to take part in this study.

This research project is funded by the National Health and Medical Research Council (NHMRC) and has received approval from The University of Queensland Human Research Ethics Committee, Approval Number: 2020002077 and the Human Research Ethics Committee of the Northern Territory Department of Health and Menzies School of Health Research, Approval Number: 2020_3923.

PFASs (per- and polyfluoroalkyl substances) are manufactured chemicals that are present in the environment, in foods and food packaging, various consumer products and in industrial applications, including fire-fighting foams. The extensive use, distribution and manufacture of products containing PFASs has resulted in widespread exposure of individuals and the environment. The general population is exposed to background levels of PFASs through food, drinking water and house dust. As a result, PFASs can be detected in blood serum samples of the general population. Certain populations have higher levels of PFASs exposure, particularly those who have produced or worked with these chemicals. Some communities living in environments that have experienced exceptional contamination may also be exposed to high levels of PFASs.

The current research study aims to measure change in the concentration of PFASs in blood of individuals who may have had higher exposure and to understand what factors are associated with the reduction of PFASs in the blood. Efforts have been made in exposed communities and occupational groups to control the exposure of PFASs in the environment. By collecting and analysing blood from individuals in exposed communities and occupational groups at different times, we can determine how effective these efforts to control exposure have been and to better understand why some individuals’ PFAS levels reduce faster than others and, for those people whose PFAS levels are not decreasing as we expect, try to understand why this may be the case. 

This study will also help us understand more about the relationship between PFAS levels and levels of other biochemical measurements of health. The study is designed to contribute to the broader research into PFAS exposure and their potential association with human health issues.

Following detection of per- and poly-fluoroalkyl substances (PFAS) contamination in the mains water at Avalon Airport in October 2022, Airservices Australia invited Queensland Alliance for Environmental Health Sciences (QAEHS) to assist with a study with the aim of better understanding the Avalon Aviation Rescue Fire Fighting Service (ARFFS) staff exposure to PFAS.  The study found evidence that the elimination of PFAS can be increased, and that blood donation can be an effective to reduce PFAS serum concentrations. The study report is available below.

Our research team are very keen to keep in touch with all participants and interested community members regarding the project.

While we had planned to regularly visit each community to present our findings, restrictions around COVID-19 have prevented this from happening so far. Until travel and holding face-to-face meetings is possible, we plan to hold regular webinar or online events where our research team can present current findings of the project and where our participants can ask any questions. Email updates will be sent to participants and will be updated on this webpage.
