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 ...
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 ...
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.

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 ...
The largest Antarctic ozone hole recorded (September 1985) 2012 retrospective video by NASA on the Montreal Protocol The Montreal Protocol on Substances That Deplete the Ozone Layer [2] is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.
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 ...

CFCs had punched a hole in the ozone layer over Antarctica; if left unchecked, the hole would have expanded to the point of eventually threatening all life on Earth.
