Deep dives
Understanding PFAS Exposure Sources
Exposure to PFAS compounds occurs not only through contaminated water but also through a variety of food sources including fish, milk, eggs, and even lettuce. These substances can migrate from their packaging—like fast food wrappers—into food items, contributing to elevated blood levels in individuals. The complexity of exposure pathways illustrates that people may not fully grasp how these materials affect their health, suggesting a need for increased awareness and research. As studies indicate, significant exposure may arise from consumer products and environmental interactions that have not yet been fully understood.
