Stream sediments have been preferred reservoir for foreign substances in the environment to contaminated areas. They are reliable indicators of environmental pollution. Special-interest territory - the Cherry stream and their surroundings - represents an area that has been permanently threatened by two sorts of contaminants, e. g. physical and chemical too. A part of contaminants transported in dissolvable form by the surface water supplies vein water and solid phase of streamsediments.The most important is the interaction between the water of sediments and inappropriate anthropogenic activity (irresponsible gardening and agricultural activities), various waste materials in wild dumps etc.. The analyses of the streamsediments samples were carried out (certificate No. 01871/101/1/2001) by the flow electrochemistry methods (EcaFlow 150GLP). The result revealed that significantly relevant are: cadmium (concentration vary within the range 0.026-1.470 mg per kg Cd of dry matter), mercury (0.012-0.266 mg per kg Hg of dry matter) and lead (4.16-25.53 mg per kg Pb of dry matter), which accounted a positive dependency.
