Surface-water/groundwater boundaries affect seasonal PFAS concentrations and PFAA precursor transformations
23 Nov 2021 | Environ Sci Process Impacts
Natural biogeochemical fluctuations associated with surface-water and groundwater boundaries may lead to PFAA precursor loss and seasonal variations in PFAA concentrations.
Impairment of human dopaminergic neurons at different developmental stages by perfluoro-octanoic acid (PFOA) and differential human brain areas accumulation of perfluoroalkyl chemicals
23 Nov 2021 | Environ Int
In a proof-of-concept study, PFOA exposure was found to disrupt the most sensitive stage of neuron development.
