RESUMO
The article covers results of studies concerning nano- and microparticles in atmospheric suspensions in snow collected in 11 points of Karakan coal extraction cluster (Kouzbass) in winter of 2011-2012. As a reference, a sample was taken on territory of Kouzbass botanical garden of Human Ecology Institute with RASc Siberian Division. All the points studied appeared to be polluted with technogenous suspensions--that proves high ecologic load on atmosphere over all territory of Kouzbass coalfield. Particles found in snow could be placed in decrement order: coal (up to 80%), natural minerals (mostly aluminosilicate and quartz) (up to 10%), vegetable detrital matter, unidentifiable technogenic particles, metals and their compounds (mostly Fe, Ba and Ti). Some areas appeared to frequently present microparticles containing rare-earth metals (rare-earth phosphates and alumophosphates prevail).
