TFA Reduces Antibody Production in Human Study at Unexpected Levels

Italian researchers have found that trifluoroacetic acid (TFA), an atmospheric byproduct of certain f-gases, reduced antibody production in human-relevant in vitro (outside the body) tests at levels similar to those caused by perfluorooctanesulfonic acid (PFOS), which has well-documented immunotoxic effects.
