‘Forever Chemicals’ show up in Wisconsin residents

A statewide study in Wisconsin found that while PFAS chemicals are present in most residents’ blood, the highest levels were found in older, higher-income white men who eat locally-caught fish.

• PFAS (“forever chemicals”) were detected in nearly all participants’ blood, with higher levels associated with older age. male gender, non-Hispanic white race, higher income and consumption of locally-caught fish.
• This was the first statewide biomonitoring study in the Great Lakes region to assess broad demographic and lifestyle associations with PFAS exposure.
• Eating microwaved popcorn was linked to slightly higher PFAS levels while fast food consumption showed no significant effect.
• Blood samples from 605 adults were tested for 38 types of PFAS using advanced lab methods that detect very low concentrations.
• Researchers emphasized that while associations were observed, the study did not establish causation and PFAS levels in Wisconsin were generally lower than national averages.

The study provides a foundational understanding of PFAS exposure patterns in Wisconsin, highlighting the need for targeted public health guidance while reinforcing that more research is needed to understand long-term health risks.
