Summary

Story summary

Lund University researchers find that very high prenatal PFAS exposure raises asthma risk in children.
The analysis covered more than 11,000 children born 2006–2013 in Blekinge County, with a 40% higher asthma incidence.
The findings tie exposure to a Ronneby PFAS contamination event, suggesting extreme exposure affects respiratory health.
Limitations include using residential data to estimate exposure, and researchers say further studies are needed.
