PFAS Uptake Studies in Plants, Chicken & Eggs

Plant Uptake Study

Defence undertook a study to evaluate how different plants uptake PFAS at a range of different water-based concentrations within a controlled environment. The information collected from the Study was used to inform the 2017 Human Health Risk Assessments for Williamtown and Oakey.

The study aimed to:
  • refine the exposure concentrations used to estimate potential exposure risks to the people in the Oakey and Williamtown Human Health Risk Assessments;
  • inform potential Human Health Risk Assessments at other Defence sites; and
  • support Government to provide advice to the local community about irrigating with groundwater and consuming edible home grown plants.
The selected test plants include: radish, beets, rocket, strawberries, alfalfa, cherry tomatoes and cucumber.

Chicken Egg Uptake Study

Defence conducted a study to assess and evaluate PFAS residue in eggs, relative to a range of intake rates by chickens, and who are exposed to a range of PFAS concentrations. It also investigated the rate that PFAS residue decline in eggs if chickens are provided with a PFAS -free drinking water supply.

The information collected from the Study was used to refine the Human Health Risk Assessments for Williamtown and Oakey and advice regarding the consumption of eggs from backyard chickens.
