Analysis of ultra short-chain PFAS in urine: method development by LC-MS/MS and first human biomonitoring results from the German National Cohort (NAKO).
Ultra short-chain perfluoroalkyl substances (USC PFAS) with C1-C3 chain lengths are increasingly important. Globally, trifluoroacetic acid (TFA) makes up the largest proportion of PFAS in the environment, however, knowledge about human internal exposure to these substances is scarce. We present a new, fast and robust h...
