Abstract

Results of a grain-size research of particles of atmospheric suspensions of the Khingan reserve in the winter of 2016 are given. The valuation method of pollution of the atmosphere offered during operation by means of ultrasonic cleaning of needles allows to obtain reliable data about composition of solid particles of an atmospheric suspension, comparable on accuracy with the analysis of tests of snow. As an indicator look we used a pine ordinary (Pinus sylvestris L.), growing in the Hingansky reserve. Needles (30—40 pieces) were carefully selected by the size (8,2 ± 0,2 cm) from one branch of a tree. Samples of needles plunged into the container with the distilled water and were processed by an ultrasound by means of a disintegrator of Sonopulse 3100 HD with a frequency of 22 kHz, 100 W and exposure 5 min. In the atmosphere of the reserve macroscopic particles with a diameter of tens and one hundred micrometers prevail, but also also microparticles (to 10 microns) in the considerable shares are found (to 26,8 %). It is shown that microsized pollution of the atmosphere of the Khingan reserve beforehand can be estimated as moderate.
