Bioconcentration and tissue distribution of shorter and longer chain perfluoroalkyl acids (PFAAs) in zebrafish (Danio rerio): Effects of perfluorinated carbon chain length and zebrafish protein content
Science
12 Mar 2019 | Environ. Pollut.
We investigated the effects of perfluorinated carbon chain length of PFAAs and protein content of tissues on the bioconcentration and tissue distribution of both shorter chain PFAAs (linear C-F = 3-6) and longer chain PFAAs (linear C-F = 7-11) in zebrafish.

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.
