MICROELEMENTS IN THE ARCTIC AEROSOL

The paper summarizes and systematizes the data on element composition of the Arctic atmospheric aerosol. The following aspects are considere d: 1) the geophysical peculiarities of the pollution substance long-ra nge transport from the mid-latitudes to the Arctic; 2) the concentrati on levels of some chemical elements in the Arctic atmosphere, their te mporal and spatial variations; 3) the mass-size distributions, the enr ichment factors and the dry deposition velocities of various elements in the Arctic atmosphere; 4) the methods for determination of the aero sol origin (natural or antropogenic) by means of its microelement comp osition analysis. The reference list consists of 125 papers which were published during the last 15 years.
