Some experts question the wisdom of allowing lawmakers to set such a scientifically based standard. These experts think so. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are perhaps the two most studied PFAS chemicals. However, they simply replaced the two original variations of PFAS PFOA (perfluorooctanoic acid) and PFOS (perfluorooctanoic sulfonic acid) with slightly different chemical compounds that have pretty much the same risk. If you really look at it, you get to see everything that's been tested for, Nadler says. Your thoughts? At the current rate of research, Birnbaum says, it will take about two years to get a basic handle on the toxicity of the whole PFAS group.

Are there some places where we need to have this class of chemicals to be safe? "A question that we all need to be asking is: What's essential?" Those findings have raised a host of new questions, first about mechanism: How do PFAS chemicals act in the body? Once PFAS chemicals make their way into water, they can also be found in plants and animals, including humans.

A commonlyheld view among environmental groups is that PFAS should at least be regulated as a single class in drinking water and the environment, to simplify the process of evaluating toxicity and deciding when to filter water. It is increasingly wellestablished that PFOA and PFOS in particular are likely both bioaccumulative and toxic. Advocates of the chemical industry often argue that each PFAS chemical should be judged separately, and that newer PFAS chemicals are less likely to be harmful due to their chemical structures. Fear has the peculiar tendency to remove the balance from our thinking. But the work is slow going. To learn more about how we keep our content accurate and trustworthy, read oureditorial guidelines. Learn more. There are relatively minor chemical differences between many of these compounds, which is why they sort of behave similarly, says Scott Bartell, professor of environmental and occupational health at the University of California, Irvine.
