You may have heard about PFAS in the news. The term PFAS refers to a group of man-made chemicals known as perfluoroalkyl and polyfluoroalkyl substances. These substances are known for being durable and are commonly found in many household items such as nonstick cookware, stain-resistant carpets, and some types of clothing. They are also used to prevent food from sticking to its packaging and are found in certain types of fire-fighting foams.

One of the concerning aspects of PFAS is that they break down very slowly, meaning they can stay in the environment—and the human body—for a long time. Research shows that these substances can accumulate in the bloodstream, and they’ve been detected in both people and animals.

Scientists are continuing to explore how PFAS may influence human health. Some studies suggest a possible connection between these substances and a greater risk of certain cancers. Other research indicates a link between PFAS and shifts in metabolism and body weight.

In the early 2000s, many products began phasing out some types of PFAS. Following that, studies showed a decrease in the levels of these chemicals in people’s blood. However, newer forms of PFAS have since been developed and introduced. Ongoing research, supported by the NIH, is aiming to understand the health impact of these newer substances. The large number and variety of PFAS compounds make this a complex task.

Scientists continue their efforts to gain deeper insights into PFAS and their potential risks.
