Summary: | During the ARK-XI/1 expedition of R/V Polarstern in July-September 1995 12 samples of aerosols were collected in lower atmosphere layer over the Laptev Sea by filtration of air through AFA-HA filters. Element composition of the samples was determined by instrumental neutron activation analysis. Average atmospheric concentrations of Cr, Mn, Fe, Co, Zn and As are higher than in other regions of the Arctic. This can be explained by natural reasons: (1) by input of particles from the surface microlayer of sea water enriched by many chemical elements, (2) by atmospheric transfer of organic matter and lithogenic material from the land, and (3) by resuspension of particles from ice-rafted sediments. In some samples anthropogenic pollution was registered. |
