What do we know about dust?

It is everywhere: on TV, in your favorite sofa cushion, in the door slit, on the lid of a pan with borsch, on a ballpoint pen forgotten on the table, and on the table itself it is visible and invisible. Lies in a gray layer and by no means pleases the eye and nose.

“Dust of Ages” is not just an established saying. In fact, for every hundredth of a second on the globe, there are millions of destructions of the “existing”, and all this turns into dust that we hate, which rises into the air with the wind, and then settles in our homes.

Scientists distinguish two “champions” in dust production: the oceans and volcanoes. If you look more widely – water and mountains. Water, breaking on the rocks with small drops of salt water, turns into salt. And then the cloud moves to the cities, where it settles on the “tops” of our hats. Volcanoes emit crushed rock into the atmosphere, which also, in turn, “comes” and strews our pavements, from which our shoes bring dust to the house. It turns out that our door mat is deposits of fossil and non-edible salt.

Another scientific fact: comets and meteorites bring extraterrestrial dust into the atmosphere. Settling, it makes our Earth heavier – annually by 10 tons.

What threatens the presence of dust “in our interior”?

Firstly, dust (not taken separately, visible only under a microscope, a dust particle, but their accumulation) is a very powerful destroyer. It’s hard to believe, but dust has an “erase effect” that is much more intense than sandpaper. Dust particles, getting, for example, into the structure of the fabric of the upholstery of a chair, rub against each other, and first your chair “loses its shine”, and then grows old – breaks. Of course, your pants also played an important role in this, but it is dust that shortens the age of your furniture.

The second nuisance dust brought with it is allergy. Our nasal mucosa, undoubtedly, does not allow most of this muck to enter the body, but the dust consists not only of Sahara sand or Dead Sea algae, but also of all kinds of chemistry that our olfactory organ can not cope with. And it began: asthma, dermatitis, conjunctivitis.

We make up a significant part of the dust ourselves: scales of our skin, saliva, nails. In my house, the concept of “dust” also fits the hair of my beloved cat, the pollen of the “window sill greenhouse”. We should not forget about bacteria and ticks either – this is an integral part of the dusty microworld.

And what is most incomprehensible is how to deal with this invasion. Wet cleaning and a vacuum cleaner cope with the dust “lying”, but those particles that are invisible to us, which “hang” above the surface during cleaning, they are not able to absorb. And therefore, after the “generalka” on our carpet, the dust, although it decreases, is not much. Even if you make a draft: how much will go – so much will return.

It remains to hope for the predictions of our science fiction writers: life without disease, problems and dust. Perhaps the creation of some kind of ecologically clean space of our premises is not so fantastic.
