Chemical Watch: PFCs in drinking water link to human blood levels

Californian researchers have found a possible link between blood levels of perfluorinated chemicals (PFCs), in the general population, and concentrations in drinking water. Meanwhile, eating fish from PFC-contaminated waters may also push up human PFC levels, according to a Norwegian study. Led by Susan Hurley from the Cancer Prevention Institute of California, researchers analysed blood PFC levels for 1,566 women enrolled in a California teachers’ study. They then used US EPA data on PFCs in water supplies, collected between 2013 and 2015 under an unregulated contaminant monitoring rule (UCMR3).
