Fifteen out of 23 popular sports bras have detectable levels of fluorine, an indicator of toxic PFAS, according to a new report from Mamavation.

Partnering with EHN.org, the environmental wellness blog and community Mamavation tested the sports bras and found levels of fluorine ranging from 10 parts per million (ppm) up to 58 ppm. EHN.org partially funded the testing and Pete Myers, chief scientist of Environmental Health Sciences, which publishes Environmental Health News, reviewed the findings.
