PFAS are a potential health risk because they can bioaccumulate in plant, animal and human tissue. Prof. Cora Young’s research team analyzed arctic ice cores, finding ultra-short-chain PFAS compounds. These breakdown components resulted from an unexpected source—chemicals intended to be eco-friendly replacements for CFCs in the late 1980s.
“Around 1990, we saw a dramatic increase in these ultra-short-chain PFAS, much more than the other PFAS.”
