Estimation of the capacity for self‐purification of transformed rivers of Khanty‐Mansi Autonomous Okrug‐Yugra (Russia)
Abstract This article presents an estimation of the self‐purification capacity of rivers flowing through an area of the Ob River basin at Khanty‐Mansi Autonomous Okrug‐Yugra, which has been significantly transformed by the oil and gas industry.

The research was done on the rivers of the Ob River basin in oil fields in 2003–2006 and 2018–2019. The coefficient of mineralization of organic matter has been used as a criterion of the rivers’ water self‐purification levels. The mineralization coefficient was based on the ratio of numbers of bacteria consuming ammonium nitrogen and polymer substances as well as saprophytic heterotrophic bacteria. According to the results obtained, most rivers draining the oil field area (75% in 2003–2006 and 79% in 2018–2019) were characterized by a low potential for self‐purification. The highest level of self‐purification criteria was obtained for two rivers: the Ai‐Pim River in the Surgut region and the Ovyn'yegan River in the Oktyabrsky region. The high level of self‐purification detected with the coeficient of mineralization ensures the maintenance of a certain trophical level and environmental balance of the aquatic ecosystem.
