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.

Magnetohydrodynamic Equilibrium And Stability | doi.org/10.13182/FST95-A11947130
Articles are hosted by Taylor and Francis Online.
According to the recent study of the magnetohydrodynamic stability for both the global and local modes of field-reversed configurations (FRCs), it is required to develop a theory including the ion's finite orbit effect which is valid in FRCs. This means that the two dimensional analysis on the poloidal surface is inevitably necessary. As the first step toward the two dimensional stability analysis, the magnetic field coordinate is obtained numerically in FRCs for the first time. Using the co-ordinate, the equilibrium properties of FRCs are examined for the preparation of stability analysis.
