Ozone is higher in concentration in atmosphere. Stratosphere contains most ozone.
Low ozone concentrations are caused in part by chlorofluorocarbons, or CFCs.
Increasing temperature increases the natural rate of decay of ozone, speeds up processes of ozone decay, and makes ozone slightly harder to make. So concentrations of ozone will net decrease with increasing temperature.
It is desirable to have small ozone hole. Because UV can't penetrate normal ozone blanket too.
The term "ozone layer" can be misleading because it implies that ozone exists in a distinct, separate layer in the atmosphere. In reality, ozone is present throughout the stratosphere in varying concentrations. So, it's more accurate to think of the ozone layer as a region of the stratosphere with higher concentrations of ozone rather than a single, uniform layer.
The stratospheric region of the atmosphere is actually a region containing a thick layer of ozone gas which is known as the ozone layer. this ozone layer contains the maximum concentrations of ozone. thus the stratosphere can be regarded as the zone of the maximum concentrations of ozone.
The region of the stratosphere that contains diminished concentrations of ozone in comparison to normal levels is called the ozone hole.
Ozone is an allotrope of oxygen which is found mainly in the stratospheric region. Some small concentrations of ozone are also present in the tropospheric region but the concentrations are of the level of parts per million so the concentrations are mainly neglected.
It doesn't matter how ozone is produced, the health concerns are the same. If ozone is encountered at high enough concentrations, it can cause shortness of breath in even healthy individuals. Asthmatics may be more sensitive to it. Most people can small ozone, at least for a time, and some will find higher concentrations to be offensive. At extremely high concentrations, where, for example, ozone may be used as a sanitizing or disinfecting agent, it may result in delayed by severe pulmonary edema (liquid in the lungs). This is why equipment that is intended to produce ozone in high concentrations, or that might do so if maladjusted, should be well ventilated or equipped with catalytic filters to destroy the ozone faster than natural decay would.
Lower ozone is bad. It is a greenhouse gas.
To form an explosive mixture with ozone, it typically needs to reach concentrations above its lower explosive limit (LEL) of 10%. Lower concentrations are safer because they are below the LEL threshold required for ignition and explosion. Ozone can be highly reactive, so higher concentrations increase the likelihood of rapid combustion or explosion when exposed to a ignition source.
Low ozone concentrations in the atmosphere are primarily caused by human activities such as the release of ozone-depleting substances like chlorofluorocarbons (CFCs) and other pollutants. These substances break down ozone molecules in the stratosphere, leading to a decrease in ozone levels.
Stratospheric region of the earth contains the max concentrations of ozone and is thus called the ozone layer.
