    "body_text": "Helmholtz-Zentrum Dresden-Rossendorf researchers compared hydrodynamic cavitation with cold plasma for destroying PFAS in contaminated water. Cavitation degraded about 37 percent of PFOS with evidence of mineralization, short of the team's greater-than-80-percent goal. Cold plasma nearly degraded both long- and short-chain compounds but released only about 35 percent of the fluorine and required more energy, leaving transformation products and possible gaseous emissions to resolve. Both results are laboratory demonstrations, not treatment-plant performance claims.",
