Even if you forget what “PFAS” stands for, it may be an environmental issue that’s close to your heart. That’s according to a new study that’s linked higher concentrations of the so-called “forever chemicals” to cardiovascular risks in middle-aged women.

Polyfluoroalkyl substances, or PFAS, are a group of chemicals that are used in many industrial activities and consumer products. Their properties made them popular additives in stain-resistant and non-stick inventions, despite the fact that they do not break down easily and can persist for hundreds of years under standard environmental conditions.

PFAS began sparking health concerns after scientists found they were bioaccumulating – building up in soils, drinking water, and even livestock. In fact, PFAS are now so widespread that nearly all Americans have detectable concentrations of at least one one PFAS compound in their blood.

Past studies have raised concerns that PFAS could impact cardiovascular health or even lower birth weights – a risk factor associated with higher rates of infant mortality.
