【 摘 要 】
The article presents the preliminary results of the study of surface waters and bottom sediments of the rivers Irelyakh, Malaya Botuobiya and Vilyuy after the technological accident in August 2018. In general, after the accident burst of the dredging site on the Irelyakh deterioration of water quality in the Vilyuy by organoleptic characteristics (chromaticity up to 20 MPC, turbidity up to 61 MPC), as well as the most important indicators such as BOD5 (up to 3.9 MPC) and COD (4.5 MPCvr, 2.2 MPC) is detected. High concentrations of suspended solids, turbidity and chromaticity are observed in the channel of the Vilyuy below the mouth of the Markha in the period 02-03 September 2018, where the bulk of the polluted water passed. In the trace element composition of water, the main pollutants are total iron (up to 22 TLV f.w., 7.5 MACw), manganese (up to 12.6 TLV f.w.), aluminum (up to 32.3 TLV f.w., 6.5 MACw) and copper (up to 37 TLV f.w.)【 预 览 】
