We live in close proximity to this mysterious substance, and sometimes it does not even notice the dust …! Where does it come from? Did you know that at home you can find micro-particles of soil from the Rostov, tiny particles of sand of the desert Karakum, the ashes of the volcano erupting somewhere in Italy, and even dust from outer space? Every year on this planet are deposited tens of millions of tons of dust. What is its origin? Scientists claim that about 70% of the dust has a natural origin, 30% is created by man. The most significant source of natural dust-soil. More info: New York Museums. The particles are blown by the winds of the earth, rising high into the sky, are transferred to different distances and are deposited. There is still a dust ocean, When the sea air thrown in little crystals of salt. At the same time accumulate in the atmosphere of minute droplets of water. They are formed by breaking waves and rising waters from the bottom of the air bubbles.

Drops quickly dry, and air enriched with salts, crystals of which rise high into the air and hover in conjunction with water vapor in the form of clouds. Another source of dust, volcanoes and forest fires across the planet. For example, a Japanese volcano Sakurajima “rewards” of humanity 14 million tons of dust per year! Next to this volcano is the town of Kagoshima is the most dust in the world! Large “providers” are dust of the desert. For example, a huge Sahara sleep Russians, Britons, Australians and sand dust in the number of 60-200 million tonnes a year. Falls to the ground and cosmic dust, along with offering of meteor showers. In addition, there are pollens, spores, fungi, fur animals, rubber tire dust from the abrasive, fiber, natural and artificial fabrics … All this “cocktail” is always present in the air and gets into our house.

Our neighbors are also unpleasant dust mites. They are very small and live in house dust. In total there are about 50 species of dust mites. They feed on dead flakes of human skin. Many mites in pillows, bedding, upholstered furniture, in carpets, in the secluded reach for the vacuum cleaner … Scientists ‘please’ us such figures: the usual double bed home to about 2 million mites! By themselves, they can not harm humans, but their selection can cause allergies. Why dust accumulates indoors? The fact that none of the most thorough cleaning is not able to change the composition of air in the room. Dust settles permanently, respectively covered her furniture and floor. Even tightly closed windows and doors for dust do not pose special obstacles, so it is fine! It will penetrate any crack. The air inside the home is always more dusty than on the street because the streets are constantly blown by the winds.
