Редкоземельные и попутные элементы в водах и донных отложениях бассейна реки Омутной (Томская область, Российская Федерация)

Abstract

The analysis of the data on a chemical composition of river waters and sediments in a the Omutnaya river (Omutnaya - Bol. Kirgizka - Tom - Ob) during 1998-2019. The main attention is given to the Omutnaya river. It is shown that intraannual changes of a chemical composition of river waters are characterized by increase from a spring flood up to winter low flow contents of substances with prevalence of the dissolved form of migration. For substances with prevalence of the weighed form of migration (such as Fe, Y, La, Ce) maxima of the total contents in the spring flood and minima during the winter period are marked. Existential changes of a chemical composition of acid extracts from sediments are shown appreciablly more poorly than in river water.
