ATMOSPHERIC AEROSOL ELEMENT COMPOSITION I N THE CENTRAL RUSSIAN ARCTIC

The article is devoted to analysis of the long-term series Of experime ntal data on aerosol element composition at the archipelago Severnaya Zemlya. The surface aerosol samples were collected during one spring m onth in 1985, 1986, and 1988 (each sample being collected for 1 - 7 da ys). Their composition was analyzed for presence of nearly 30 elements by neutron activation analysis-or spectral analysis of emission. The mean values of concentration for the majority of elements are within l imits known from the literature for the other Arctic regions. Temporal variations of the element concentrations are caused by various air ma sses coming to the archipelago Severnaya Zemlya in accordance with the atmospheric synoptical conditions. Comparison of the element composit ion of aerosol samples and of the emissions of some industrial regions (with simultaneous back-trajectory air masses analysis) made it possi ble to identify a number of source regions for the aerosol antropogeni c components. These source regions are located in Russia, Ukraine, Wes tern Europe and North America.
