  • The destruction of the ozone layer damage in the end how much it?

  •      The destruction of the ozone layer culprit is (freon refrigerant), freon is synthesized in the 1920s, the chemical property is stable, does not have flammability and toxicity, as refrigerants, foaming agent and cleaning agent, is widely used in the field of household appliances, foam, daily chemicals, cars, fire equipment. In late 80s, freon production reached a peak, the yield reached 1 million 440 thousand tons. Before the control of freon, emissions of Freon into the atmosphere around the world has reached 20 million tons. Because they are in the atmosphere of the average life expectancy for hundreds of years, so emissions most still left in the atmosphere, most of them still remain in the troposphere, a small part of entering the stratosphere. In the troposphere are fairly stable, freon, up into the stratosphere, under certain meteorological conditions, under the strong ultraviolet radiation is decomposed, the decomposition, releasing chlorine atoms with ozone will have a knock on effect on, will continue to destroy ozone molecules. Scientists estimate that a chlorine atom can destroy tens of thousands of ozone molecules.

          After the destruction of the ozone layer, the ability to absorb ultraviolet radiation is greatly reduced, so that the opportunity for human to accept excessive ultraviolet radiation is greatly increased. On the one hand, excessive ultraviolet radiation can destroy the human immune system, people's own immune system disorders, respiratory system infectious diseases had a significant increase in the number of; on the other hand, excessive ultraviolet radiation will increase the incidence of skin cancer. According to statistics, about 100 thousand people worldwide die each year from skin cancer, most cases are related to excessive ultraviolet radiation. Ozone depletion of the ozone layer 1%, the incidence of skin cancer will increase by 2%. In addition, excessive ultraviolet radiation will induce a variety of eye diseases, such as cataract, corneal tumors, etc..

           In such a case, the protection of the ozone layer of the atmosphere, is every citizen of our time does not allow the obligations and responsibilities of the slow. Foshan Deshun Household Electric Appliance Co., Ltd. grand launch of Dong Hao brand cold media recycling machine sent came in very useful, this tool equipment can be air conditioners, refrigerators, cars and other equipments are in need of repair, the cold medium recovery to a tank, and can be used repeatedly. That was a decrease of waste unnecessary costs, also control the refrigerant emissions to the atmosphere.
