This article focuses on the analysis of different rivers role in the Caspian Sea contamination. On the base of generalized fund researches and also published and authors own researches a quantitative and qualitative evaluations of contaminated matters supply to the sea from the PreCaspian states have been fulfilled and fraction contribution to sea contamination by different rivers in Azerbaijan has been noted.
It has been defined among the rivers of Azerbaijan Kura and Araks rivers (which flow into Kura) are contaminated by heavy metals such as lead, cadmium, arsenic and other contaminating matters such as phenols, mercury salts, and copper which are widespread in ecosystem of the Caspian Sea. Radionuclides coming from Volga basin to the Caspian Sea are of great danger.
There are data of bottom sediments contamination in the coastal part of Azerbaijan sector of the Caspian Sea. The results of model calculations of contamination distribution in the Caspian Sea under influence of climatic conditions are exemplified by Volga river and effluent waters of Baku.
On the base of this data the authors summarize that ecology of the Caspian Sea is a vital problem and ecological safety of this reservoir is the priority for each country.
