Continuous sampling of aerosols is carryed out on the NW coast of the Kandalaksha Bay of the White Sea. Aerosol matter from 30 filters collected in summer and autumn 2013 and in spring 2014 was studied by scanning electron microscopy. Elemental composition of aerosol matter was determined by inductively-coupled plasma mass-spectrometry (ICP-MS). The major part of aerosol particles collected in summer is of biogenic origin. Heavy metal concentrations in aerosols are on the Arctic background level. The distribution of trace element concentrations is characterized by simultaneous peaks of different elements. Backward trajectory analysis shows increasing of Ni and Cu concentrations corresponding to air masses coming from western part of the Kola Peninsula. That suggests influence of smelters.
