Abstract

The impact from mining and large-scale agricultural activities on levels and migration of metals within the Kola River and Lake Imandra has been studied in detail. Evaluation of the pollution status in the Kola River is based on sampling of the dissolved (0.22 µm) fractions and also metal accumulation in aquatic bryophytes on 12 sites along the Kola River and its tributaries during an annual cycle. In Lake Imandra the sampling of dissolved (<0.45 µm) and suspended (<0.45 µM) fractions from 18 sampling levels within the water column was performed on three sampling occasions. Also, a sediment core and porewater were sampled. Major and trace elements (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Sr and Zn), total and particulate organic car...
