LOUISVILLE (KT) – If you’ve wondered why some people who drink alcohol develop serious liver problems while others don't, a study from University of Louisville researchers published in “Toxicological Sciences” suggests the answer might be hidden in everyday sources such as drinking water, food packaging or even non-stick cookware.

Scientists at U of L, along with colleagues from Boston University and the University of Massachusetts Lowell, have identified perfluorooctane sulfonate (PFOS) as a potential environmental factor that worsens alcohol-associated liver disease.

PFOS is a man-made chemical belonging to the group known as per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals" because they do not readily break down in the environment or the human body.
