A training course "Ecology and environmental protection" was held at the Samarkand branch of the Tashkent State University of Economics.
On April 5, 2023 at 11:00 a.m. in room 404 A, the next "ECOLOGY" of the "ECOLOGY AND GREEN ECONOMY" student science club, which is being held under the "Natural, social sciences and physical culture" and "Food and agricultural economics" departments AND ENVIRONMENTAL PROTECTION" TRAINING COURSE was held.
During the training course, the chairman of the "ECOLOGY AND GREEN ECONOMY" student science club, associate professor Z.S. Bobomuradov made a presentation on the topic "Atmospheric air protection".
The following questions were considered in the training course:
1. The atmosphere, its composition and importance for the organism.
2. Air pollution
3. Sources of air pollution.
4. Protection of the atmosphere.
Atmospheric air polluting production objects and processes in discussions and suggestions in the roundtable discussion of the training course "Atmospheric air protection". Monitoring of atmospheric air pollutant gases. Convention on reduction of gases that deplete the ozone layer. Global changes in the atmosphere. Information about climate change and dangerous meteorological phenomena was provided.
The air envelope that surrounds our planet is called the atmosphere (atmosphere in Greek means "air layer without a vapor envelope"). The thickness of the atmosphere reaches 3000 km.
The importance of the atmosphere in life on earth is great, these are:
1. It allows the exchange of heat and substances between living organisms and inanimate nature.
2. Protects against ultraviolet rays.
3. Holds water in the ground, ensures water circulation.
4. Influences the redistribution of solar heat on the Earth's surface and moderates the climate.
5. Ensures the presence of organic life on Earth.
The atmosphere is of great importance for the respiration of our planet and the living organisms that live on it. In addition, the earth's atmosphere serves as a blanket that protects the surface of our planet from overheating during the day and cooling down at night.
The atmosphere also protects the earth from many meteors from space. Meteors burn up in the atmosphere and cannot reach the earth.
The atmosphere (near the earth's surface) consists mainly of nitrogen (78.08%) and oxygen (20.95%), with smaller amounts of argon (0.93%), carbon dioxide (0.03%), helium, there are neon, xenon, krypton, hydrogen, ozone, ammonia, iodine and other gases (0.01%).
Oxygen is the most important gas in the atmosphere. All living organisms need it to breathe.
Its amount in the atmosphere is 1015 tons. Oxygen is included in protein, fat, and carbohydrates that make up organisms
