In a groundbreaking study published in the Journal of Environmental Quality, researchers from the University of Notre Dame have traced the movement of PFAS, or "forever chemicals," through the Great Lakes ecosystem. The research, which analyzed 42 years of data and nearly 2,500 samples, highlights the health risks associated with these chemicals and their pervasive presence in human tissues.
Understanding PFAS Distribution in Ecosystems
PFAS chemicals are found in a variety of products, from frying pans to skincare items, leading to measurable levels in nearly all individuals in the United States. The recent study focused on six commonly tested PFAS chemicals, revealing significant trends in their distribution across various organisms.
According to Gary Lamberti, an aquatic science professor and co-author of the study, “What we’re finding is that the food web itself is a vehicle for transferring these chemicals from one organism to another.” This meta-analysis provides a more holistic view of PFAS movement compared to previous studies.
Health Risks Linked to PFAS Exposure
PFAS exposure is associated with numerous health issues, including decreased fertility and a higher prevalence of certain cancers. Chemicals have been detected in human blood, liver, kidneys, and lungs. The study emphasizes that people can be exposed to PFAS through the food they consume.
