title: Ni and Cu migration and accumulation in forest ecosystems on the Kola Peninsula.
abstract: Biogeochemical cycles of Ni and Cu in pine forests on the northern tree line (Kola peninsula) in the background and industry-disturbed areas have been investigated. Total, bio-available and exchangeable concentrations of Ni and Cu in the soil, atmospheric Ni and Cu fluxes and soil water migration, and metal uptake by plants are considered. In the polluted area, forest ecosystems are seen as biogeochemical barriers which may attenuate intensity of Ni and Cu migration down the soil profile. A quantitative assessment is given of the role of dominating forest plants and soil horizons as barriers to heavy metal fluxes.
