New PFAS Blood Measurements: What the Latest Data Reveals

Lisa Bos · 2026-09-29

You've probably heard about PFAS—those "forever chemicals" that seem to be everywhere. Well, there's fresh data from the Dutch National Institute for Public Health and the Environment (RIVM) that gives us a clearer picture of what's actually in our blood. And honestly? It's a mixed bag. ### What Exactly Are PFAS? PFAS stands for per- and polyfluoroalkyl substances. They're a group of thousands of man-made chemicals used since the 1940s to make products resistant to water, grease, and stains. Think non-stick pans, waterproof jackets, food packaging, and firefighting foam. The problem? They don't break down easily—hence the nickname "forever chemicals." They accumulate in our bodies and the environment over time. ### The Latest Findings from RIVM The RIVM recently measured PFAS levels in blood samples from people living in the Netherlands. The goal was to see if levels are going down and to identify which PFAS compounds are most prevalent. The results show that while some older PFAS (like PFOS and PFOA) have decreased over the years, newer ones are taking their place. It's a bit like playing whack-a-mole—regulations on one set of chemicals lead to the introduction of others that may be just as concerning. ### Why Should You Care? PFAS exposure has been linked to a range of health issues, including thyroid problems, liver damage, and even some cancers. But here's the thing: the science is still evolving. What we do know is that almost everyone has some level of PFAS in their blood. The question is, how much is too much? And what can we do about it? ### What Can You Do to Reduce Exposure? While it's impossible to avoid PFAS entirely, there are steps you can take to minimize your exposure: - **Filter your water:** Consider using a reverse osmosis filter or activated carbon filter, especially if your water source is known to have PFAS. - **Choose your cookware wisely:** Avoid non-stick pans that may contain PFAS; opt for stainless steel, cast iron, or ceramic instead. - **Check food packaging:** Limit fast food and microwave popcorn, as their packaging often contains PFAS. - **Be mindful of stain-resistant products:** Furniture, carpets, and clothing with stain-resistant coatings often contain PFAS. - **Stay informed:** Follow updates from health agencies and demand stricter regulations. ### The Bigger Picture The RIVM's measurements are a reminder that PFAS pollution is a global issue. While the Netherlands is taking steps to monitor and regulate these chemicals, it's a worldwide challenge. The good news? Awareness is growing, and more research is being funded to understand the health impacts and find safer alternatives. ### What's Next? The RIVM plans to continue monitoring PFAS levels in the population and to study the effects of newer compounds. They're also working on ways to reduce emissions and clean up contaminated sites. It's a long road, but every measurement brings us closer to understanding the problem—and hopefully, to solving it. So, the next time you hear about PFAS, remember: it's not just a scientific curiosity. It's about our health, our environment, and the choices we make every day. Stay informed, stay proactive, and maybe think twice before reaching for that non-stick pan.
