In this article, titled “PFAS toxicological risk status–A topic of much debate,” published in the ABA Section of Environment, Energy, and Resources (SEER) September/October issue of Trends, Koll and Sheldon give their insights on evolving and uncertain PFAS toxicological risk status and how that has affected potential PFAS regulations at both the federal and state levels.
Koll and Sheldon write in the article that, “While there are thousands of toxicological studies on PFAS, many of these have low levels of confidence or are based on animal, not human, studies. Although perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) are by far the most studied PFAS compounds, the strength of evidence for their health effects varies.”
While there is some consensus by the scientific community on certain PFAS health outcomes, they also note that, “There appears to be significant miscommunication by government health agencies that minimizes or over-generalizes health risks of PFAS to affected communities, medical practitioners, and the judicial system. The miscommunications stem from one big data gap—PFAS in mixtures.”
To learn more about PFAS in mixtures and what that means for the toxicology risk of PFAS, read the full article written by Caron Koll and Jack Sheldon on the American Bar Association website.
