Taking the “F” out of forever chemicals
The right solvent mix breaks down perfluorinated organic acids Source and more : Science.org SHIRA JOUDAN AND RYLAN J. LUNDGREN Per- and polyfluoroalkyl substances (PFAS)—sometimes called “forever chemicals” because of their chemical stability—are synthetic molecules widely used in consumer products (1). Ironically, the characteristics that make these compounds useful, such as lipoand hydrophobicity, high thermal stability, and resistance to

Increasing stratification as observed by satellite sea surface salinity measurements – Nature.com
Source and more : Nature.com Science Reports Abstract Changes in the Earth’s water cycle can be estimated by analyzing sea surface salinity. This variable reflects the balance between precipitation and evaporation over the ocean, since the upper layers of the ocean are the most sensitive to atmosphere–ocean interactions. In situ measurements lack spatial and temporal

Outside the Safe Operating Space of a New Planetary Boundary for Per- and Polyfluoroalkyl Substances (PFAS)
Rainwater & TapWater abstract It is hypothesized that environmental contamination by per- and polyfluoroalkyl substances (PFAS) defines a separate planetary boundary and that this boundary has been exceeded. This hypothesis is tested by comparing the levels of four selected perfluoroalkyl acids (PFAAs) (i.e., perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexanesulfonic acid (PFHxS), and perfluorononanoic acid
