Ecogeochemical and bioindication assessment of transformation of ecosystem in process drafting of primary deposits of diamonds in Yakutia
In paper we considered two approaches assess the status of natural ecosystems: ecogeochemical and bioindication. Ecogeochemical assessment is given based on the total pollution index of the soil cover (Zc) with the calculation of regional and local background, concentration coefficient relative to the of regional background (Кс). Bioindication assessment of the environment carried out on indicators distortion of the stability of the organism. The main criteria are the magnitude of fluctuating asymmetry characteristics of the structure of the venation of the leaf lamella Betula platyphylla Sukacz. Directly on the study site there is a general tendency to change the geochemical conditions of the soil substrate. General trends in change the quality of the environment show that the most favorable situation environment can be traced at a distance to 2.3 km away from sources of anthropogenic impacts. And magnitude integral parameter increases in moving to the industrial area.
