engines in the factories and in houses probably the most important source of ozone. Due to depletion of ozone layer, the Earth is exposed to the ultra-violate radiation and These radiations can rays cause harmful effect to living beings on the Earth. Danger to Our Environment, ozone is a natural trace component of the atmosphere. The plan was held in the London in 1990. French physicists, charles Fabry and, henri Buisson. For this reason, the use of CFCs in aerosols has been banned everywhere. Some pollutants in the atmosphere like Chlorofluoro-carbons (CH3) cause the depletion of ozone layer. In recent years, scientists have sounded alarms internationally about the depletion of the ozone layer, citing chemical pollution as the major cause. It called for the cessation of CFC production by 1996. Although decreases in stratospheric ozone are well-tied to CFCs and there are good theoretical reasons to believe that decreases in ozone will lead to increases in surface UVB, there is no direct observational evidence linking ozone depletion to higher incidence of skin cancer and eye. All of these compounds are excellent refrigerants, and CFC-12 is marketed by DuPont as Freon.3.
Most of the atmosphere's ozone is found between 20 and. They have done all that efforts for the safe country and better atmosphere. The role of third body (M) is to absorb the excess energy liberated by the above reaction and thereby 03 molecules are stabilized. The ozone layer protects the Earth from the ultraviolet rays sent down by the sun. Our earth is enveloped by an atmosphere, which is divided into Troposphere, Stratosphere, Mesosphere and Thermosphere. A study by marine biologists in the seas around Antarctica showed that higher levels of ultraviolet radiation reduce algal productivity by 6-12 per cent. Possible Effects of Ozone Depletion. The exact amount of ozone that can be found varies, the seasons influence it; it is also different in different places on the Earth. It was started for betterment of the earth in all over the world. 1, this layer can absorb between 93 and 99 per cent of the ultraviolet radiation from the. Other chemicals, such as bromine halocarbons, as well as nitrous oxides from fertilizers, may also attack the ozone layer. The plan was held in the Vienna in 1995.
