Proceedings of the National Academy of Sciences, 2003 In this issue of PNAS, Babior et al. (1) extend the published series of experiments by Wentworth et al. (2–5) in which it was shown that antibodies catalyze the generation of ozone by a water oxidation pathway. The overall process is postulated to involve more than one equivalent of the lower-energy singlet state of molecular oxygen (1O2) and to ...

Rapid Increases in Warm-Season Surface Ozone and Resulting Health Impact in China Since 2013
Environmental Science and Technology Letters, 2020 China’s nationwide ozone monitoring network initiated in 2013 has observed severe surface ozone pollution. This network, combined with the recent Tropospheric Ozone Assessment Report (TOAR) data set, offers a more comprehensive view on global surface ...

Antioxidant effect of an ozonized theobroma oil formulation on damaged-inflammatory rat skin
Grasas y Aceites, 2011 The aim of this study was to determine whether a cosmetic formulation elaborated with ozonized theobroma oil may exert beneficial effects in the restoring of the antioxidant activity on the skin of rats previously irradiated with ultraviolet light. 0.5 g

Stratospheric sink for chlorofluoromethanes: chlorine atomc-atalysed destruction of ozone
Nature, 1974 Chlorofluoromethanes are being added to the environment in steadily increasing amounts. These compounds are chemically inert and may remain in the atmosphere for 40–150 years, and concentrations can be expected to reach 10 to 30 times present levels ...
