Maximum permissible concentration of copper in water of reservoirs of sanitary and household water use makes 1 mg/dm3 (limiting a harm sign — all-sanitary), in water of fishery reservoirs - 001 mg/dm
The factors defining changes of concentration of manganese are a ratio between a superficial and underground drain, intensity of its consumption at photosynthesis, decomposition of a phytoplankton, microorganisms and the highest water vegetation, and also processes of its sedimentation on a bottom of water objects.
98,7% of all anthropogenous emissions of this metal fall to the share of the enterprises of nonferrous metallurgy, from them 71% are carried out by the enterprises of Norilsk Nickel concern located in Polar and Nickel, Monchegorsk and Norilsk, and about another 25% of emissions of copper are carried out in Revda, Krasnouralsk, Kolchugino and in others.
Compounds of cobalt are in natural waters in dissolved and a suspension the quantitative ratio between which is defined by a chemical composition of water, temperature and values. The dissolved forms are presented by generally complex connections, including with organic substances of natural waters. Compounds of bivalent cobalt are most characteristic for a surface water. In the presence of oxidizers possibly existence in noticeable concentration of trivalent cobalt.
Get to natural waters of compound of cobalt as a result of processes of their leaching of mednokolchedanovy and other ores, of soils at decomposition of organisms and plants, and also with sewage of steel, metalworking and chemical plants. Quantities of cobalt arrive from soils as a result of decomposition of vegetable and animal organisms.
