The U.S. military plans to keep incinerating toxic firefighting foam, despite health risks
News
27 Jan 2019 | The Intercept
The U.S. military is moving ahead with plans to collect and destroy unused firefighting foam that contains the hazardous chemicals PFOS and PFOA. But in trying to solve one environmental problem related to these persistent chemicals, which have caused massive drinking water contamination, the Defense Department may be creating another.

A review of human exposure to PFAS: substantial contribution from seafood
Science
30 Nov 1925 | Environ Health Prev Med
In Japan, rivers contaminated by industrial PFAS discharges have led to high levels of long-chain PFAS in seafood such as cod, clams, and shrimp, and because seafood is a dietary staple, this pathway now accounts for the majority of human PFAS intake and explains the higher blood concentrations observed in the Japanese population compared to other countries.
