Abstract

Dust - small particles in the air, which settle down under the influence of their own weight, but for some time may be in the air in an overheating condition. Dust particles can have different sizes, color, chemical nature, shape, etc. A feature of the dust is that it may be non-toxic, but adsorbing on its surface gaseous, steamy or liquid compounds, acquires completely different properties and increases this danger both for plants, and for animals and people.
