The analyses encompassed data from 4661 (1990), 7301 (1995), 6764 (2000) and 5600 (2005) sampling sites. As exemplary case studies revealed that other factors besides atmospheric deposition of metals influence the element concentrations in mosses, the moss datasets of the above mentioned surveys were analysed by means of bi-and multivariate statistics in order to identify factors influencing metal bioaccumulation. In the analyses we used the metadata recorded during the sampling as well as additional geodata e.g. on depositions, emissions and land use. Bivariate Spearman correlation analyses showed the highest correlations between Cd and Pb concentrations in mosses and EMEP modelled total deposition data (0.62 ≤ r s ≤ 0.73). For Hg the correlations with all the tested factors were considerably lower (e.g. total deposition r s ≤ 0.24). Multivariate decision tree analyses by means of Classification and Regression Trees (CART) identified the total deposition as the statistically most significant factor for the Cd and Pb concentrations in the mosses in all four monitoring campaigns. For Hg, the most significant factor 8 in 1990 as identified by CART was the distance to the nearest Hg source recorded in the European Pollutant Emission Register, in 1995 and 2000 it was the analytical method, and in 2005 CART identified the sampled moss species. The strong correlations between the Cd and Pb concentrations in the mosses and the total deposition can be used to calculate deposition maps with a regression kriging approach on the basis of surface maps on the element concentrations in the mosses.

Институт леса Карельского научного центра РАН Рассматриваются особенности формирования почв и почвенного покрова на территории Карело-Кольского региона. Прослежена связь протекающих процессов почвообразования с климатом, почвообразующими породами, рельефом местности и растительным покровом. В зональном аспекте показана специфика почвообразования и дана подробная характеристика сформировавшихся почв и строения почвенного покрова Кольского полуострова и Карелии. На основании Классификации почв России (2004 г.) на Кольском полуострове выделены 12 типов почв, которые объединяются в 6 отделов и 3 ствола. На территории Карелии выделены 15 типов почв, которые входят в 7 отделов и 3 ствола, что свидетельствует о большем разнообразии в составе почвенного покрова. К л ю ч е в ы е с л о в а: почвы; почвенный покров; Кольский полуостров; Карелия; факторы почвообразования; классификация почв. N. G. Fedorets , O. N. Bakhmet. PECULIARITIES OF SOIL AND SOIL COVER FORMATION IN THE KARELIA-KOLA REGION The factors behind the formation of soils and the soil cover in the Karelia-Kola region are considered. The connections of the ongoing soil formation processes with the climate, parent rocks, terrain, and plant cover are traced. The zonal specificity of soil formation is demonstrated, and the existing soils and structure of the soil cover in the Kola Peninsula and Karelia are characterized in detail. According to the Russian Soil Classification (2004), Kola Peninsula soils fall into 12 types belonging to 6 divisions and 3 trunks. The territory of Karelia has 15 soil types within 7 divisions and 3 trunks, proving the diversity of soils in the soil cover is higher.
