“During the last 20 years, the reference values ​​for PFAS in drinking water, surface water and soil have decreased dramatically due to new knowledge about their toxicity. As a result, the levels in the environmental media they are now pervasively above baseline levels,” the study adds.

Finally, the experts noted that “due to the global spread of PFAS, environmental media everywhere will exceed environmental quality guidelines designed to protect the Human health and we can do very little to reduce PFAS contamination. In other words, it makes sense to define a planetary limit specifically for PFAS and, as we conclude in the paper, this limit has now been exceeded.”
