PFAS, common chemicals used to make everything from pizza boxes to take-out containers, are associated with risk of miscarriages, according to a new study from Yale. 

More than 200 Danish pregnant women provided samples of their blood for the study. The findings suggest a 80% to 120% higher risk of miscarriage for women whose cells tested with the highest levels of PFAS.

Dr. Zeyan Liew, who led the study at Yale, says more studies should be done to see what PFAS exposures are “modifiable.”

“Which means that, you know, we might have a chance of preventing some of these miscarriage events that could be avoided.”

Liew says about 10% to 20% of all diagnosed pregnancies end in miscarriage. And, he says avoiding PFAS can be hard for pregnant women because the chemicals enter and stay in the body long before pregnancy. They’re also common in drinking water.
