Swedish study: High levels of PFAS in drinking water connected to asthma in children

The risk of developing asthma is 40 percent higher among children born to mothers who were exposed to very high levels of the 'forever chemicals' PFAS, according to a new study from Lund University.

The study includes children born to women who lived in the municipality of Ronneby in southern Sweden at a time when many of its inhabitants were exposed to very high levels of PFAS from a contaminated drinking water source.

"We grouped children by how high a PFAS exposure their mothers had leading up to the years they were born and we found that the children whose mothers had a really high level of PFAS, we saw about a 40 percent higher risk of developing asthma than children whose mothers were never exposed to this drinking source," Annelise Blomberg, researcher at Lund University, tells Radio Sweden.
