In this regard, Russians are advised to take care of their eyes
Doctor of Geological and Mineralogical Sciences Vladimir Syvorotkin said that a huge ozone hole covered northern Eurasia from the Atlantic to the Pacific Ocean, most of which fell on Russia.
The center of the anomaly, according to the specialist, is located in the north of Western Siberia, where ozone losses reach 50 percent. This means that "We are dealing with an Antarctic-scale ozone hole," the scientist quotes regnum.ru. Vladimir Syvorotkin also said that ozone losses in Moscow are 22 percent, and in St. Petersburg - 35 percent.
The scientist recalled that in winter, when thick clothes protect the human body, including from ultraviolet radiation, his eyes remain vulnerable, especially if bright sunlight is additionally reflected from the snow.
Ozone hole - a local drop in ozone concentration in the ozone layer of the Earth. According to the most common theory, their appearance is indirectly provoked by human activity. The ozone hole was first discovered in 1985 in the Southern Hemisphere. At that time, its diameter was over a thousand kilometers. Further research showed that there are quite a lot of ozone holes on Earth.
Many data earlier testified in favor of the fact that the destruction of the ozone layer is accelerated by freons, so some of them are officially prohibited to use today. However, comparatively recent studies indicate that these measures may not be sufficient, as "short-lived substances" such as iodine, bromine and chlorine also contribute to the depletion of the ozone layer.
