Geochemistry of Suspended Particulate Matter in the Marginal Filter of the Pregolya River (Baltic Sea)

Abstract

The article discusses the results of studying the marginal filter of the Pregolya River in different seasons. Three transformation stages of dispersed sedimentary material are distinguished: gravitational, colloidal–sorption, and biogenic. Study of the chemical composition of suspended particulate matter at all marginal filter stages showed variation in the composition of suspension-forming elements, as well as strong enrichment of suspended particulate matter in a number of trace elements, which can be explained by pollution. Matrix correlation analysis of chemical element concentrations revealed strong links between elements.
