Results of a study of co-migration of trace elements and organic matter in a river flow in a boreal zone

This work describes the evolution of migration forms of true dissolved compounds and colloidal entities using an integrated approach with molecular mass distribution and differences in the association of trace elements with organic matter and Fe-oxide colloids in the soil water-bog-river-lake system. One major problem is obtaining reliable information on the processes of redistribution deposited forms and trace element complexes during the phase transformation of organic humic compounds in a series of high-molecular-weight organic matter of bog soils to colloidal and truly dissolved forms, as well as to the river and lake fine sediment (suspension) as a transit zone and deposit region.
