Eating One Freshwater Fish Equals A Month Of ‘Forever Chemicals’ Water: Study

At a glance

  • A new study by Environmental Working Group scientists finds that consumption of just a single serving of freshwater fish per year could be equal to a month of drinking water laced with the “forever chemical” PFOS at high levels that may be harmful.
  • Researchers calculated that eating one fish in a year equated to ingesting water with PFOS at 48 parts per trillion, or ppt, for one month.
  • The study bolsters EWG’s long-running calls for strict regulation of PFOS and the other toxic “forever chemicals” known as PFAS, in addition to more tests of food such as fish, since diet is thought to be a major source of PFAS exposure for Americans.
