Superficial drain from farmsteads in Krasnoselkupsky disctrict being a factor of the Taz river contamination

The ecological conditions of water ecosystems in Krasnoselkupsky district are subject to natural and technogenic impact, with a considerable increase of the latter over the past 20 years. The rivers flowing near or through the residential areas highly exposed to industrial impact - construction at water protection zones, oil pollution, contamination with heavy metals and other specific substances. The impact of superficial drain from the settlements on the river bed is sufficient, resulting in technogenesis of geomorphological processes of the river network. The researchers conducted an integrated environmental study of the Taz River within the villages of Krasnoselkup and Tolka in the spring and summer of 2012. The study was aimed at evaluating the impact of surface superficial drain from residential areas on the ecological state of the water body. Bottom sediment is a good sorbent material able to concentrate most pollutants and contaminants. All insoluble and partially soluble compounds are mainly concentrated in the sediments...
