Two per- and polyfluoroalkyl substances discovered along with 53 other compounds never seen before in the literature
Database screening and high-resolution mass spectrometry have been combined to identify 55 chemicals in the blood samples of pregnant women and their newborns that have never before been reported in samples, including 42 so called ‘mystery’ compounds whose sources, uses and presence in consumer products are unknown.
Researchers from the University of California San Francisco (UCSF), together with colleagues at the California Environmental Protection Agency and UC Berkeley, found 109 chemicals in the blood samples of the mothers and their babies, including seven per and polyfluoroalkyl substances (PFASs).
