MATERIAL AND ELEMENTAL COMPOSITION OF INSOLUBLE PARTICLES IN SNOW OF NORTH-WESTERN KANDALAKSHA BAY COAST OF THE WHITE SEA
Particulate matter of snow collected in March 2016 in locality of the White Sea Biological Station of M.V. Lomonosov Moscow State University was analyzed with scanning electron microscopy coupled with energy-dispersive X-ray spectrometry and inductively-coupled plasma mass-spectrometry. Insoluble particles in snow are presented by biogenic, lithogenic and anthropogenic particles. Major-element composition of anthropogenic particles (combustion spheres) responds to average composition of the Earth’s crust as well as composition of single lithogenic particles. Trace-elemental composition of particulate matter of snow corresponds to average composition of the Earth’s crust too. At the same time Ni, Cu, Cd, Sb, W, Pb, Bi, U content in insoluble fraction is higher than in the Earth’s crust. These elements commonly arrive from anthropogenic sources as result of long-term atmospheric transport as accompanying elements. The highest enrichment is typical to Cd, Bi, Pb and Sb.
