On influence of technogenic sewage on physical and chemical characteristics of the freshwater reservoir
The effect of industrial sewage on the physico-chemical characteristics of Lake Imandra has been estimated. The numerical modelling with the program complex Selector-C has shown that industrial sewage leads to increase of concentration of Na+, K+, Cl, F, SO4-2, SiO2, . The water is saturated with respect to Ca, Na, K, P, Al, Si. If the sewage volume is three times greater, the value of pH throughout the water body increases by 0.4.

Evaluation of heavy metals (Ni and Cu) balance of the water-shed area of subarctic lake (case study of the Chunozero Lake)
The typical area with widespread rocks of the "gabbro" mineral association (Pl+Amp) within the Fedorova Tundra intrusive has been studied. It has been shown that "gabbro" is a result of autometamorphic reworking of rocks with the three-mineral gabbronoritic association – Pl+Opx+Cpx.
