Research the atmospheric suspension of the small settlement (on the example of Romna's village in Amur oblast)

Article is devoted to research the atmospheric suspensions of the Romna village (Amur oblast) by means of laser granulometry methods. It is shown that the volume fraction of ecologically significant microparticles (less than 10 microns) in air of Romna village makes from 10,5 to 16%, and particles from 10 to 100 microns - from 33,3 to 80,9%. These data are estimated as an adverse background for development the bronchopulmonary diseases. The share of large particles (from 400 microns and above) makes from 52,3 to 55,1%. The conclusion is drawn, what even in the territory of one small settlement with the population to 3000 people can be observed various ecological the characteristic of the air environment. The atmospheric suspension of Romna village consists of particles, diverse by the size, which average arithmetic diameter fluctuates from 29,14 to 911,6 microns.
