      Hi! I don’t have specific information on PFAS chemicals and the health effects on humans. I see that they have voluntarily phased out two of the big ones, and are working on replacement chemicals called GenX. (That is great news!) Something that you have to remember is that when we make discoveries it answers problems we have in the moment, but can create even bigger problems down the road.

      I know the health effects are not good and we do not have a full understanding of just how bad and extensive the damage to humans and communities we live in. Unfortunately we humans have created a lot of useful products that are ending up causing a lot of harm.

      The half-life of PFAS in humans varies widely, from several days to more than 15 years, depending on which PFAS. Longer chain chemicals have been found to be the most persistent. Longer half-lives can impact bioaccumulation and potentially related downstream health effects. Resource: https://www.battelle.org/insights/white-papers/pfas-and-human-health

      Here is a great informational EPA resource that helps address some of these questions around PFA exposure, human risk, and the state of the research being done.

      So I personally don’t. However, a resource that is often available to you when asking about chemical effects on human health are the material safety data sheets (MSDS). Those are public knowledge and easily available, and have a lot of great information about how a chemical can be handled and what the risks to humans and the environment are. That may not help fully in your specific question, but it’s a good resource for you to know about for a starting point.

      Information can be found in reputable science journals and articles. I would suggest looking into this topic on your own. I am doing my best to eliminate my PFAS exposures in my home (using cast iron, ceramics, glass, and stainless steel when cooking instead of teflon products) I also have been using more wooden or metal options when selecting cooking, eating, or drinking items. That’s just my preference for avoiding plastic compounds. And some plastic food containers just make the food taste bad.
      Regarding the information question. I advise you to continue to search news and journal articles from reputable sources ( https://cen.acs.org/index.html has had some good articles recently. and you can follow the resources from the story too). Some companies have pledged to stop using the compounds and you can find information on their websites.
      is a good resource site.
      They also link to a list of PFAS-free products

      PFAS is a forever chemical, that breaks down slowly overtime. PFAS can be found in water, soil, aquatic life, and the air. Additionally, there are thousands of PFAS chemicals, and some health effects include reproductive effects, developmental delays, increased cancer risk, and reduced immune systems. The EPA is addressing PFAS currently: https://www.epa.gov/pfas/increasing-our-understanding-health-risks-pfas-and-how-address-them
