HEAVY METALS IN THE GEOLOGICAL-ECOLOGICAL SYSTEM OF THE BOTTOM SEDIMENTS OF THE CONTINENTAL SLOPE OF THE BLACK SEA
Journal Title: Geologia i poleznye iskopaemye mirovogo okeana - Year 2018, Vol 14, Issue 2
Abstract
The results of research on the distribution of some heavy metals in the geological-ecological system of the Black Sea sediments are presented. It was found that the average concentrations of trace elements in the geological-ecological system of bottom sediments of the continental slope on the border with the aquaecosystem are much lower than those for the surface layer of the geological-ecological system of bottom sediments of the shelf. The distribution of maximum concentrations of nickel, cadmium and mercury in an array of sediments has once again confirmed the leading role of an organic matter in the accumulation of heavy metals during natural sedimentation processes.
