Concentrations of bioavailable forms of metal compounds in bottom sediments of lakes and the enrichment factor as attributes of reservoirs' ecological situation (by the example of Murmansk region lake
Abstract. Concentrations of Al, Fe, Sr, Zn, Cu and Ni bioavailable forms in bottom sediments (BS) of lakes of the Murmansk region have been studied. The investigated lakes (the Bolshoy Vudjavr, Malyi Vudjavr, Nyudjavr and the Guba Belaya of the lake Bolshaya Imandra) belong to the catchment area of the Bolshaya Imandra and are influenced by human impact. The highest percentage of bioavailable forms most of metals has been found in BS of the lake Nyudjavr. According to the enrichment factors of elements and Risk Assessment Code the most dangerous ecological situation has been defined for the lake Nyudjavr.
Keywords: bioavailable forms of metal compounds, sediments, lake
