Abstract
The article presents primary results of the study of sediments in the composition of the snow cover background territories of taiga zone of European North-East of Russia using the method of dynamic light scattering. The average size of particles in the snow is 828 ± 311 nm, and the average volumetric fraction of particles less than 1000 nm in samples of melt water is 66.6%. Spatial differentiation in the distribution of particle sizes in the snow of the areas under study is detected. The conclusion about the possible impact of the relief on the granulometric composition of the particles is made. The relationship between the content of elements in suspended particles of snow and their size fractions is shown.
