"Exposure to some toxic Pfas “forever chemicals” may increase the risk of having multiple miscarriages, new peer-reviewed research has found.

The study, which tracked about 200 women in China, found those who had at least two miscarriages, or unexplained recurrent spontaneous abortions, showed higher levels of several types of Pfas in their blood. The study adds to a long list of reproductive harms associated with Pfas exposure.

“Prior studies have identified that Pfas were associated with adverse pregnancy outcomes, but the potential influence of Pfas’s exposure on [recurrent miscarriages] remained uncertain,” the study’s authors, with the Chinese Center for Disease Control and Prevention, wrote. “Our investigation identified significant associations between [some Pfas] and increased risks of unexplained recurrent spontaneous abortions.”
