Estimation of the capacity for self‐purification of transformed rivers of Khanty‐Mansi Autonomous Okrug‐Yugra (Russia)

Abstract

This article is part of the special series "Environmental Monitoring on Global and Local Scales." The series documents cases of the current state of environmental assessment and tracking using different approaches: in situ monitoring, geoinformation modeling, and risk-based assessment. The work was originally presented at the conference "Ecological Monitoring: Methods and Approaches," held September 2021 in Krasnoyarsk, Russia, and co-organized with the European and Russian-Language Branches of Society of Environmental Toxicology and Chemistry.

Introduction to the Special Series “Environmental Monitoring on Global and Local Scales”

“…However, the sensitivity of boreal ecosystems to anthropogenic pressure is well known and is caused by their weak ability to recover owing to a long season of low temperatures. The article by Shornikova and Arslanova (2022) assesses the ability of small rivers, which flow through the area of Western Siberia, have been transformed by the oil and gas industry, and are subject to prolonged periods of freezing, to self-purify. The rivers are components of the Ob River basin, one of the largest rivers in the world flowing into the Kara Sea.…”
