    Titled “Stratospheric sink for chlorofluorocarbons: chlorine atom-catalyzed destruction of ozone”, the article laid out how a class of chemicals was wreaking havoc with the Ozone Layer ...

  3. Ozone depletion - Wikipedia

    en.wikipedia.org/wiki/Ozone_depletion

    2-rich air flows in from lower latitudes, the PSCs are destroyed, the enhanced ozone depletion process shuts down, and the ozone hole closes. [52] Most of the ozone that is destroyed is in the lower stratosphere, in contrast to the much smaller ozone depletion through homogeneous gas-phase reactions, which occurs primarily in the upper ...

    en.wikipedia.org/wiki/Ozone_and_biology

    Delivering ozone dissolved in liquids is not straight forward as ozone gas has limited solubility in water or oil. [15] When treating the water or other liquids themselves, the solubility is less of a problem as pure ozone gas can be discharged into the liquid until the desired effect is achieved. Charvet ozone generators in a laundry circa 1903

    Ozone is a greenhouse gas, [32] and changes in its atmospheric abundance due to human activity have radiative forcing effects. Ozone absorbs both ultraviolet (UV) radiation from the sun and infrared radiation emitted from Earth's surface. [4] Human activity has depleted ozone in the stratopshere and increased its abundance in the troposphere ...

    For the last few decades, scientists studied the effects of acute and chronic ozone exposure on human health. Hundreds of studies suggest that ozone is harmful to people at levels currently found in urban areas. [78] [79] Ozone has been shown to affect the respiratory, cardiovascular and central nervous system. Early death and problems in ...
