SPOKANE — Most likely, you’re aware of PFAS. Or at least your bloodstream is, considering that the chemicals have been detected in 98% of Americans, according to the National Health and Nutrition Examination Survey.
PFAS, or per- and polyfluoroalkyl substances, are chemicals known for their versatility and persistent nature. This is due to strong carbon-fluorine bonds, NBC reported, which then creates the opportunity for PFAS to accumulate in the human body.
The most common contaminated consumables and items include “drinking water, soil and water at or near waste sites, fire extinguishing foam, food, food packaging, household products and dust, personal care products, biosolids and manufacturing or chemical production facilities that produce or use PFAS,” according to the Environmental Protection Agency.
Humans are susceptible to exposure via drinking, eating and breathing PFAS, the EPA said.
If exposed, observed effects on the human body are numerous.
Dr. Catherine Karr studies these effects as an environmental epidemiologist and pediatric environmental medicine specialist at the University of Washington. She is involved with the National Institutes of Health and holds an MD, as well as a PhD in the field.
