Sophisticated tool helps measure exposure levels to PFAS
Shelley Liu, PhD, discusses a tool developed to help measure exposure to thousands of synthetic chemicals known as per- and polyfluoroalkyl substances (PFAS), which we encounter everyday with potentially adverse health impacts. She said, “There are few existing methods to quantify total exposure burden of individuals to mixtures of PFAS chemicals that are found in our everyday lives. For the first time we've developed a PFAS burden calculator that takes into account patterns of exposure to many chemicals within the PFAS family, and not just individual chemical concentrations which current methods are focused on. As a result, this robust tool could be extremely useful for biomonitoring by regulatory agencies, and for disease and health risk assessment."
