Sep 20, 2016 · This seminar presentation summarizes Ozone layer depletion. It introduces ozone and the ozone layer, how ozone depleting substances like CFCs react with ozone leading to its destruction. The consequences of ozone layer depletion include increased skin cancer and other health issues.
Apr 6, 2014 · The document also explains that chlorofluorocarbons deplete stratospheric ozone, causing seasonal ozone holes over Antarctica, and outlines the health and environmental impacts of ozone layer depletion and how to protect the ozone layer and ourselves from UV radiation.

Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by ultraviolet radiations and release chlorine atoms. These atoms react with ozone and destroy it.
Researches say that the unregulated launching of rockets results in much more depletion of the ozone layer than the CFCs do. If not controlled, this might result in a huge loss of the ozone layer by the year 2050.
The nitrogenous compounds such as NO2, NO, N2O are highly responsible for the depletion of the ozone layer.
The ozone layer has been found to be depleted by certain natural processes such as Sun-spots and stratospheric winds. But it does not cause more than 1-2% of the ozone layer depletion. The volcanic eruptions are also responsible for the depletion of the ozone layer. Following is the list of some main ozone-depleting substances and the sources from ...
Humans will be directly exposed to the harmful ultraviolet radiation of the sun due to the depletion of the ozone layer. This might result in serious health issues among humans, such as skin diseases, cancer, sunburns, cataract, quick ageing and weak immune system.
Strong ultraviolet rays may lead to minimal growth, flowering and photosynthesis in plants. The forests also have to bear the harmful effects of the ultraviolet rays.
Planktons are greatly affected by the exposure to harmful ultraviolet rays. These are higher in the aquatic food chain. If the planktons are destroyed, the organisms present in the food chain are also affected. The depletion of the ozone layer is a serious issue and various programmes have been launched by the government of various countries to pre...
Reduce the use of ozone depleting substances. E.g. avoid the use of CFCs in refrigerators and air conditioners, replacing the halon based fire extinguishers, etc.
The vehicles emit a large amount of greenhouse gasesthat lead to global warming as well as ozone depletion. Therefore, the use of vehicles should be minimised as much as possible.
Most of the cleaning products have chlorine and bromine releasing chemicals that find a way into the atmosphere and affect the ozone layer. These should be substituted with natural products to protect the environment.

Nov 6, 2023 · Ozone layer depletion is the decline of the ozone layer in the upper atmosphere. This occurs when ozone molecules come into touch with and are destroyed by atoms of chlorine and bromine found in the atmosphere.
ozone are increasingly being observed in rural areas as well. Stratospheric ozone, in contrast, plays a highly beneficial role. It absorbs most of the sun’s biologically damaging ultraviolet radiation and only allows a small amount to reach the Earth's surface. The ozone layer screens out almost all the harmful
Jul 8, 2024 · Ozone layer depletion, is simply the wearing out (reduction) of the amount of ozone in the stratosphere. Unlike pollution, which has many types and causes, Ozone depletion has been pinned down to one major human activity.
