Deflagration of ozone can be triggered by a spark and can occur in ozone concentrations of 10 wt% or higher. [35] Ozone can also be produced from oxygen at the anode of an electrochemical cell. This reaction can create smaller quantities of ozone for research purposes. [36]
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.

Most of the ozone production occurs in the tropical upper stratosphere and mesosphere. The total mass of ozone produced per day over the globe is about 400 million metric tons. The global mass of ozone is relatively constant at about 3 billion metric tons, meaning the Sun produces about 12% of the ozone layer each day. [1]

Ozone is least concentrated in the ground layer (or planetary boundary layer) of the troposphere. Ground-level or tropospheric ozone is created by chemical reactions between NOx gases (oxides of nitrogen produced by combustion) and volatile organic compounds (VOCs). The combination of these chemicals in the presence of sunlight form ozone.
The ozone layer visible from space at Earth's horizon as a blue band of afterglow within the bottom of the large bright blue band that is the stratosphere, with a silhouette of a cumulonimbus in the orange afterglow of the troposphere. The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet ...
Scientists spent years campaigning for a ban on the ozone-damaging chemical CFC-11, but 30 years after it was phased out in the 1987 Montreal Protocol, someone somewhere is breaking the rules.
The state Department of Health warns that unhealthy levels of ozone can cause throat irritation, coughing, chest pain, shortness of breath, increased susceptibility to respiratory infection and ...
