EPA issues final rule regulating “forever chemicals”
The Environmental Protection Agency announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.
According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.

Results of measurements of diverted plasma parameters in several stellarator type devices (Heliotron E, Saturn, Uragan-2, Uragan-3, Uragan-3M) are analyzed. A diverted plasma flow distribution appears to depend not only on the magnetic configuration properties but on confined plasma parameters, methods of plasma heating, the level of edge turbulence, etc. In some cases it turns possible to elucidate the factors affecting strong inhomogeneity of diverted plasma flows.
