Effect of Stratospheric Ozone Depletion on Aquatic Ecosystems

Influence of depletion of the stratospheric ozone layer on aquatic ecosystems Introduction Over the years, advances in technology and science have had a great impact on our global society. Various human factors, such as increased combustion of fossil fuels and widespread use of synthetic chemicals, have a major impact on the Earth's atmosphere and the ozone layer. Ozone depletion The ozone layer of the stratosphere is a natural means to protect the earth from the sun's ultraviolet rays.

Chlorofluorocarbon (CFC) and other halogenated ozone depleting substances (ODS) are the main causes of chemical ozone depletion. The total amount of available halogen (chlorine and bromine) in the stratosphere can be calculated and is called equivalent effective stratospheric chlorine (EESC). CFC is from Thomas Midgley, Jr. It was invented in the 1930's. Before the 1970s it was used as an aerosol spray propellant and as a cleaning process for precision electronic equipment. They are also by-products of certain chemical processes. Important natural sources of these compounds have never been discovered - their presence in the atmosphere is almost entirely by human production. As mentioned above, when such ozone-depleting chemicals reach the stratosphere, they dissociate by ultraviolet rays and release chlorine atoms.
