In Khmelnytsky Oblast International Day for the Preservation of the Ozone Layer in 1985,

in 22 countries have signed the Vienna Convention for the Protection of the Ozone Layer, two years later - on September 16 signed a protocol of Montreal on Substances that Deplete the Ozone Layer, under which participating countries shall restrict and completely stop the production of ozone-depleting substances. In1994 General Assembly proclaimed 16 September the International Day for Preservation of the Ozone layer. Ozone layer - a kind of shield from a mixture of gases, which protects the planet from harmful effects of a significant proportion of solar radiation, so that there is life on the planet. That is why it is so important for our state and its reliability. In the 80 years of the twentieth century, scientistsnoticed that in some places ozone is reduced, and in some regions - catastrophic rate. At that time there was such a thing as the "ozone hole", which was recorded in the region of Antarctica. Since all mankind closely relates to the study of the ozone layer and the impact on it of certain substances. There are many reasons for the weakening of the ozone shieldand caused by human activities. Scientists have identified a number of groups. This - the emission of water vapor and nitrogen oxides from engines of supersonic transport planes and missiles hloroftorovuhletsi (CFC) or freon - "holodohenty" in refrigerators and air conditioners, propellants for aerosol mixtures, foam blowing agents in fire extinguishers, electronic cleanersdevices for chemical cleaning of clothes in plastic production. Also highly dangerous "enemies" of the atmosphere also belongs to methyl bromide. This gas is used in agriculture as a means of plant protection. But methyl bromide kills not only pests in the soil, but also ozone in the atmosphere, even in higher layers than freon. In everydayin life we ??enjoy all sorts of sprays, aerosols (deodorants, hair spray, air fresheners, polishes, etc.), which also adversely affect the ozone layer. We can not prevent ozone holes, but keep ozone even at the household level, people can. Reported at
