Monitoring the quality of the waters of the main inflows of the Lake. Baykal made the Selenga River from the border with Mongolia to Selenginskoj of the Delta, including the 9 sections located on the section from p. Naushki to Murzino. During the whole period of monitoring river water had satisfactory oxygen regime. Oxygen saturation of water changed within 45-106%. Minimum saturation was observed in paragraph observations near the village of Selenginsk (in the range 0.5 km below with. Selenginsk) in the period, the private channel. Reaction of medium within a year has changed from neutral to alkaline. Exceeding of MPC from p. Naushki during the year was registered on 9 indicators of water quality of 17 insurable. Extras are fluoride, aluminum, manganese and nickel. In 100% of samples taken were exceeding the maximum permissible concentrations of manganese content,in 77.8% of copper, 71.4%-55.6%, total iron-zinc. For these ingredients water pollution is defined as the characteristic. Trudnookislâemymi organic substances pollution-resistant; nickel, aluminum, petroleum products, phenols and volatile. The maximum concentration of iron was 24.07 (21.38 MPC), copper-23.09 (4.0 TIMES MAC), zinc-04.12 (1.3 MPC), nickel-17.05 (1.5 TIMES), manganese-04.12 (9.1 TIMES MAC), it is difficult-oxidation of organic substances-20.08 (1.7 MPC), phenols, 23.09 (2.0 Mac), petroleum products-20.02 and 20.06 (1.2 Mac). Compared with the previous year there had been an increase in the maximum concentration of total iron, zinc and nickel. Decreased the content of organic matter hardly oxidized hydrocarbonic substrata, copper, aluminium, manganese and petroleum products. Exceeding of MACS in the water of the River near Novoselenginsk noted on 6 (in 2011 was-7) ingredients chemical composition of 13 defined. On the occurrence of the cases exceeding the MPC was determined by the water pollution on the content of total iron and copper as a characteristic, zinc and hardly oxidized hydrocarbonic substrata of organic substances-sustainable, organic and legkookislâemyh phenols is unstable. In the water of the river recorded maximum concentrations of zinc (1.5 TIMES)-06.12, iron (23.5 MPC)-27.06, phenols (2 TIMES)-26.04 and 22.05, copper (7.0 Mac)-25.07, labor-nookislâemyh organic substances (1.9 MPC)-25.07, legkookislâemyh organic substances (1.3 MPC)-22.05.
