Agency for Toxic Substances and Disease Registry | A large number of studies have examined possible relationships between levels of per- and polyfluoroalkyl substances (PFAS) in blood and harmful health effects in people. However, not all of these studies involved the same groups of people, the same type of exposure, or the same PFAS. These different studies therefore reported a variety of health outcomes. Research involving humans suggests that high levels of certain PFAS may lead to the following … |
ATSDR Clinician Guidance on PFAS | It is possible that PFAS contributed to your health problems but there is no way to know if PFAS exposure has caused your illness or made it worse … Based on what we know at this time, there is no reason to think your health problem is associated with exposure to PFAS. |
