Abstract Significant levels of ozone have been detected in a reaction flask that was designed for studies using negative air ions generated from corona discharge. While diluting the gas in the vessel at the rate of 1.5 liters/min., more than 1.0 ppm O3 was measured in the vessel when grounded water was present. Ozone levels were much less (15 ppb) in ambient air near the ion generator. Even in the absence of water, O3 levels were only 7 ppb in the reaction flask. Without the corona discharge apparatus, levels of ozone in the gas phase (with water present) averaged 6 ppb. These results demonstrate that when negative air ions are generated from corona discharge in the presence of water, significant levels of ozone are produced. Therefore, O3 could be directly responsible for many of the oxidizing effects that have been reportedly due to negative air ions.
