Abstract
Long-term monitoring studies of the chemical composition of water of Lake Komarinoe (Murmansk Region, North-West Russia) have been carried out in order to assess the quality of surface water in the territory of the development of the apatite-nepheline deposit Oleniy Ruchey. A clear reliable tendency has been revealed to increase the pH water value, mineralization, the content of basic ions, nitrate ion NO3 – in recent years, as well as a number of trace elements (Sr, Cu, Mo, F), several times higher than the maximum permissible concentrations of harmful substances for water of fishery ponds. According to the content of nutrients, the lake is characterized at the present time as eutrophic. The sharp increase in the content of compounds of the biogenic element (nitrogen) can lead to the bloom development of potentially toxic algae and cyanobacteria. Lake Umbozero, which receives water from Lake Komaninoe, is also at risk of developing water bloom processes and pollution.
