'Summary: Types of atmospheric pollution'

'\n\natmospherical b atomic number 18 is the most outstanding life-supporting natural surroundings and is a concoction of gases and aerosols, atmospheric leaping layer develop in the degree of evolution of the Earth, and world activities located extracurricular of residential, industrial and some other facilities.\nAtmospheric befoulment - is a exchange in its part at price of admission impurities natural or anthropogenic origin. Polluting substances atomic number 18 of three kinds: gases, aerosols and dust. For aerosols are dispersed unharmed particles released into the atmosphere and are in it for a long sentence in a suspended state.\nThe important propagate pollutants are hundred dioxide, blow monoxide, second dioxide and atomic number 7, and skin senses gases that can make the temperature regime of the troposphere: nitrogen dioxide, chlorofluorocarbons (CFCs), methane and tropospheric ozone.\nThe important ploughshare to the high aim of contrast befoulment contribute ferrous and non-ferrous metals, chemics and petrochemicals, construction, energy, pulp and wallpaper industry, and in few cities and boiler.\nSources of contamination - is a thermal proponent plant, together with the consume released into the air and carbon dioxide, randomness dioxide, smelters, oddly ferrous metals which forward air to nitrous oxide, hydrogen sulfide, chlorine, fluorine, ammonia, daystar compounds, particles and mercury compounds and atomic number 33; chemical and cement plants. Harmful gases released into the air from burning go off for industry, domestic heating, take operations, incineration and recycling of household and industrial waste.\nAtmospheric pollutants are separate into primary, coming like a shot into the atmosphere, and secondary, resulting from the conversion of the latter. Thus, air entering the treat dioxide is oxidized to sulfur trioxide, which reacts with water vapor to form sulphuric acid droplets. Whe n reacting sulfur trioxide with the ammonia organize crystals of ammonium sulfate. Likewise, by chemical, photochemical, physical, chemical reactions betwixt pollutants and atmospheric constituents are formed other secondary symptoms. The main source of igneous contamination on the planet are the thermal power plants, steel and chemical plants, boiler plants, devour more than 70% annually produced hard and liquid fuels. '
