• [Public comment] Draft scientific opinion on the risks to human health related to the presence of perfluoroalkyl substances in food

  Policy

  24 Feb 2020

  The European Food Safety Authority is holding consultation for the proposed PFOA+PFOS+PFHxS+PFNA tolerable weekly intake of 8 ng/kg of body weight per week. Parts of the European population exceed this level with fish, fruit, and eggs being the largest sources of exposure. Comment period ends on April 20, 2020.

• Determinants of serum concentrations of perfluoroalkyl acids (PFAAs) in school children and the contribution of low-level PFAA-contaminated drinking water

  Science

  18 Feb 2020 | Environ Sci Process Impacts

  The drinking water variable was found to be 16% (PFOA) to 78% (PFHxS) of the variation in serum PFAA concentrations, suggesting that low-level-contaminated drinking water is a significant source of exposure for children in Sweden.

• Combined effects and toxicological interactions of perfluoroalkyl and polyfluoroalkyl substances mixtures in human liver cells (HepG2)

  Science

  18 Feb 2020 | Environ. Poll.
