Per- and Polyfluoroalkyl Substances in Canadian Fast Food Packaging

Environmental Science & Technology Letters, 2023
A suite of analytical techniques was used to obtain a comprehensive picture of per- and polyfluoroalkyl substances (PFAS) in selected Canadian food packaging used for fast foods (n = 42). Particle-induced gamma ray emission spectroscopy revealed that 55% of the samples contained 10 800 μg F/m2.
