Man and the Ozone

People and ozone ozone may be one of the most important molecules. No, it is not because human beings are derived from ozone, but because it forms a protective layer on the earth that allows them to grow life on land. Before the ozone layer is formed, the sun's rays strike the earth without being disturbed and block it with fatal UV rays. However, there are life in the ocean, especially the life of plants. Especially because it is algae that people are worried about, the lifetime of this plant does not appear to be important.

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.

Ozone depletion is mainly caused by artificial substances. In the last century, humans brought in gases and chemicals into the atmosphere and immediately destroyed the ozone layer. This ingestion makes human being more vulnerable to UV - B radiation, which is known to cause skin cancer and other genetic abnormalities. As the dream of supersonic transport became a reality, scientists introduced the possibility of ozone depletion for the first time in the late 1960s. Scientists have long realized that nitric oxide (NO) can react with ozone (\ (O_3 \)) to form \ (O_2 \) molecules, but scientists have noticed that \ (NO \) The half-life of the molecule is too short. I enter the stratosphere. The possibility of \ (NO \) reacting with stratospheric ozone has not been discovered until commercial supersonic jets (they fly in the stratosphere and fly at much higher altitude than conventional jet aircraft)
