Purpose - to develop guidelines for a comprehensive definition of chemical contamination of sediments and aquatic environments, including level of pollution, the bioavailability of metals and assess their toxicity. Research methods - atomic absorption spectrometry, gas chromatography-mass spectrometry, high performance liquid chromatography, atomic emission spectrometry with inductively coupled plasma photometry. Mainl results - check the correlation HMs containing compounds Mn (II), the faction "clay + silt" and organic carbon. Sediment contamination levels assessed using internationally accepted environmental standards. The water-soluble humic significantly understate the correctness of the anionic surfactants using a standard extraction-photometric method. Practical results, put into practice method for determination of volatile sulfide (sulfide removed from the sediment under the action of HCl in the cold, AVS), as well as metals, which together with the extracted (total [SEM]). Optimized method of analysis of sediments tested on real samples. Novelty - the ways of eliminating interference by GC to determine anionic surfactants. Shown that the formation of polymer gidroksoform thorium at all studied concentrations is observed in aqueous media simulating the natural water, despite the large number of constants related to polymer gidroksoformam. Scope - environmental protection, water conditioning and quality control of water systems.
