Chemical-Class Submixture Screening Reveals Drivers of Endocrine Disruption in Personalized Human Blood POP Mixtures.

ABSTRACT: Multiple studies demonstrate mixture effects arising from the interactive toxicity of environmental chemicals in human blood, but identifying the main toxic drivers remains challenging. In a recent proof-of-principle in vitro study, we showed that personalized mixtures (PMs), reconstructed from 24 persistent organic pollutant (POPs) concentrations measured in individual blood samples from Swedish adults, induced unique interindividual effects on H295R cell viability and steroidogenesis. Here, we followed up by testing submixtures of four PMs (PM#3, PM#4, PC1-OC-Mix, and PC2-PFAS-Mix), separated by the chemical classes perfluoroalkyl substances (PFASs), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs).
