Why is ozone considered a pollutant in the ozone layer?
Ozone in the ozone layer is not at all a pollutant but it is something without which no ozone layer may have existed. Ozone can be considered as a pollutant in the stratospheric region but in the stratosphere or the ozone layer it is of full or complete use. No harms there.
What part is the ozone layer?
There are no parts to the ozone layer. Ozone is found in all layers of the atmosphere, with near zero concentrations at very high altitudes and near the Earth's surface. The lower portion of the stratosphere reaches peak ozone concentration (9-10 ppm), and this is usually referred to as the ozone layer. In the winter at one of Earth's poles, an ozone hole forms. The size of the is a function of contaminants that may be found at those altitudes that accelerate the otherwise natural decay of ozone.
How is the ozone near the Earth different from the ozone in the stratosphere?
Ground level ozone is produced in smog from combustion products. The concentrations are usually low, but still may be hazardous to susceptible individuals (such as people with asthma) or through prolonged exposure. Ozone forms from oxygen in the air during periods of high sunlight and temperature. Nitrogen compounds in smog increase its production. When breathed, ozone corrosively oxidizes lung cells, reducing breathing capacity. Stratospheric ozone, on the other hand, is produced by short-wave ultraviolet light from the Sun. The concentrations there would be very hazardous to humans (if we could breathe at those altitudes). Ozone formation prevents ultraviolet rays from reaching the surface, where they can adversely affect the cells of living things. Ozone decays fairly rapidly in "normal" air, so neither location can transfer any significant amount of ozone to the other location. Ground level ozone is an air pollutant with harmful effects on the respiratory systems of plants, animals and humans. Stratospheric ozone filters potentially damaging ultraviolet light (UV-B) from reaching the Earth's surface.The ozone is considered a pollutant after a rainstorm. It is because it is largely man caused.
When will The hole in the stratospheric ozone layer over the Antarctic expected to not recover?
The stratospheric ozone layer over Antarctica is expected to gradually recover due to global efforts to reduce ozone-depleting substances, primarily through the Montreal Protocol. However, full recovery is projected to take several decades, with estimates suggesting it may not return to pre-1980 levels until around 2060 to 2070. Factors such as climate change and atmospheric dynamics could influence this timeline, but current scientific consensus indicates recovery is on track.
How can the ozone gas be reduced?
Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth's stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone over Earth's polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena, there are also springtime polar tropospheric ozone depletion events.The details of polar ozone hole formation differ from that of mid-latitude thinning, but the most important process in both is catalytic destruction of ozone by atomic halogens.[1] The main source of these halogen atoms in the stratosphere is photodissociation of man-made halocarbonrefrigerants (CFCs, freons, halons). These compounds are transported into the stratosphere after being emitted at the surface. [2] Both types of ozone depletion were observed to increase as emissions of halo-carbons increased.CFCs and other contributory substances are referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (280-315 nm) of ultraviolet light (UV light) from passing through the Earth's atmosphere, observed and projected decreases in ozone have generated worldwide concern leading to adoption of the Montreal Protocol that bans the production of CFCs, halons, and other ozone-depleting chemicals such as carbon tetrachloride and trichloroethane. It is suspected that a variety of biological consequences such as increases in skin cancer, cataracts,[3] damage to plants, and reduction of plankton populations in the ocean's photic zone may result from the increased UV exposure due to ozone depletion.

What are the health concerns dealing with corona produced ozone?
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.

Why decrease of ozone layer is a cause for worry?
Because it is said that the ozone layer is the main barrier against Ultra-violet rays coming from the Sun, and such rays may increase skin cancer and also can increase global warming.

CFC's may cause ozone depletion by?
CFC's may cause ozone depletion by reacting with ozone. They react and decompose them to form other chlorine and fluorine compounds thus depleting the ozone layer.
Chloroflourocarbons may be harming the ozone layer by?
CFC's may be harming the ozone layer. They do it by depleting the ozone, decomposing into single atoms.
Why does a reaction slow down with time?
The reactant concentrations decrease
Where was the first ozone hole found?
Joseph Charles Farman is the British geophysicist who, together with Brian Gardiner and Jon Shanklin, published the discovery of the ozone hole over Antarctica. Their results were first published on May 16, 1985.--wikipedia
