| Abstract: | Data of 34 elements, including heavy metals, halogens, rare earth elements, U, and Th in 139 moss samples, collected in Central Russia in 2000–2002 in the Tver and Yaroslavl regions and in the northern part of the Moscow region, are presented. Factor analysis with VARIMAX rotation was applied to identify possible sources of the elements determined in the mosses. The seven resulting factors represent crust, vegetation and anthropogenic components. Some of the factors were interpreted as being associated with ferrous smelters (Fe, Zn, Sb, Ta); combination of non-ferrous smelters and other industries (Mn, Co, Mo, Cr, Ni, W); an oil-refining plant, and oil combustion at the thermal power plant (V, Ni). The geographical distribution patterns of the factor scores are also presented. Dependency equations of elemental content in mosses versus distance from the source were derived. |
