Assessment of Polymetalic Pollution of the Dnieper River by the Method of Calculation of the Background Content of Heavy Metals in Dreissena Bugensis

ABSTRACT

The statistically reliable excess of the background level of heavy metal content in Dreissena bugensis soft tissues was offered as the pollution criterion of some areas of the Dnieper River. The standard valuation methods for the treatment of geochemical data were used to assess the background value of heavy metal content and its threshold level. The median and the median absolute deviation (MAD) of concentrations provide the most adequate estimation of the background levels. The comparison of metal contents in mussels from 24 studied areas of the Dnieper with the threshold level allowed determination of the pollution degree of some riverbed areas.
