Взвесь в Балтийском море: распределение и химический состав

New data are presented on chemical composition of dispersed sedimentary matter sediment in the Baltic Sea. The suspended matter-forming components are considered – biogenic opal, organic matter, and lithogenic substance, as well as the Fe, Mn and trace elements. Seasonal variability in the distribution of these components in the water column from surface to bottom is established. Chemical composition study has revealed enrichment of suspended matter by number of trace elements in the whole water column that is explained by both man-made pollution, and natural processes in water (organic matter degradation, formation hydrogenic forms of Fe and Mn, adsorption on natural sorbents). Matrix correlation analysis of concentrations of chemical elements revealed relationship between the elements.
