Microelements Accumulation in sediments. Note I: Cadmium Accumulation.

The aquatic environment takes up the contaminants, often immobilises them in sediments and renders them in time the geological substratum with or without modification of the sediment biochemistry and/or can be taken up by plants that contribute significantly to existing or newly introduced behavioral toxicity potential or existing metals. The sampling, processing and preservation of sediment samples in order to determine the content of metals was based on the appropriate standards. The two water monitoring sections, upstream and downstream of the studied area, highlighted the Cd concentrations on the basis of which the level of contamination was established, which was subsequently confirmed and justified by the loading of these parameters in the sediment.
