Reactive oxygen and nitrogen species (RONS) is the collective term for short-lived, chemically reactive molecules and ions containing oxygen and/or nitrogen. In the context of this wiki they are the proposed active agents in Plasma-Activated Water (PAW), produced when a Non-Thermal Plasma (Cold Atmospheric Plasma) discharge contacts water.
Members commonly cited
- Hydrogen peroxide — a relatively long-lived oxidising species among the group.
- Nitrite and nitrate — nitrogen oxides that dissolve into water and contribute to the pH shift of plasma-activated water.
- Peroxynitrite-related species — highly reactive intermediates formed from the interaction of oxygen- and nitrogen-derived species.
Why they matter
RONS are the reason plasma-activated water differs chemically from untreated water: they raise the oxidation–reduction potential and, through the acids formed from nitrogen oxides, lower the pH. Their short lifetimes mean the properties of treated water decay over time.
Evidence status
This page describes the chemistry as generally understood. It does not report measured concentrations, dosages, or effects from the source dossier, whose ingested capture is incomplete and contains no such data.
