Childhood Exposure to ‘Forever Chemicals’ May Cause Lifelong Bone Damage
Childhood exposure to PFAS, also known as “forever chemicals”, may be causing significant harm to bone development, potentially leading to lifelong consequences. This alarming revelation comes from new research published on March 21, 2026, in the Journal of the Endocrine Society. The study discovered that teenagers with higher levels of these toxic chemicals exhibited notably lower bone density, especially in their forearms. This raises concerns about an increased risk of fractures and osteoporosis in the future.
Researchers from the University of North Carolina at Chapel Hill closely monitored 218 children from birth until they reached the age of 12. They measured blood concentrations of four common PFAS chemicals at various stages of life. The study revealed that 12-year-old children with higher PFAS levels – particularly perfluorooctanoic acid (PFOA) – had significantly lower bone mineral density compared to their peers with the least chemical exposure.
Dr. Jessie P. Buckley, a professor of epidemiology at UNC Chapel Hill and the lead author of the study, emphasized the importance of adolescence as a crucial period for bone development. “Adolescence is a key period for building strong bones, and achieving optimal bone mass during this time can reduce lifelong risks of fractures and osteoporosis,” she explained. “Our findings suggest that reducing PFAS exposure during key developmental windows could support healthier bones throughout life.”
The study found that the effects of PFAS exposure were particularly pronounced in girls and occurred regardless of the timing of exposure during childhood. PFAS, or per- and polyfluoroalkyl substances, are synthetic chemicals found in a multitude of consumer products. These include nonstick cookware, food packaging, water-resistant clothing, and contaminated drinking water. These compounds are persistent in the environment and accumulate in the human body over time.
Experts recommend the following measures to minimize exposure to PFAS:
- Check what your local water utility is doing to reduce PFAS.
- Use NSF-certified water filters at home.
- Avoid nonstick cookware.
- Steer clear of food in fast-food wrappers and takeout containers.
