PFAS levels in human livers decreased by 94% over 24 years, but new PFAS emerge

What they found

Total PFAS concentrations in human livers decreased by 94% over 24 years, with a 68% decrease after adjusting for demographics. However, the PFAS profile shifted, and a ~950-fold variability was observed since 2019.

What they studied

Researchers measured 54 PFAS in 211 adult human liver specimens collected from 2000 to 2024 to identify temporal trends, relative abundance, and demographic predictors of liver burden.

Takeaways

The abstract focuses on findings regarding PFAS levels and trends in human livers; it does not provide personal how-to steps for individuals.

About this paper

This biomonitoring study analyzed 211 adult human liver specimens collected over 24 years (2000-2024). It provides insights into temporal trends and demographic factors influencing hepatic PFAS burden, highlighting the inadequacy of current targeted PFAS analysis.
