摘要

1. By many parameters, the contamination of the river water and the sediment extends up to 50 km from the sewage discharge site. 2.The contaminated river water and sediment do not reach inhabited places thanks to natural purification processes (deposition, sorption, decay of organic substances, etc.). 3. According to the obtained data, the Sister sediment up the river from Klin is essentially enriched with cadmium whose source is obviously the runoff from the aviation town. 4. The conducted calculation of heavy metal forms shows that the river water is undersaturated relative to the solid phase, which means that adsorption on suspended matter dominates in the natural purification process. 5. Considerably higher concentrations of heavy metals in the sediment were detected. This constitutes a risk of secondary contamination in water bodies. 6. Bacterial processes are intensifying. The number of saprophyte and pathogenic micro-organisms is growing and contamination response-specific forms are appearing. 7. The number, biomass, and diversity of fresh water invertebrates are falling because of dying out of oligosaprobic forms.
