【 摘 要 】

The content of heavy metals in sterlet (Acipenser ruthenus) organs in the middle course of Ob river was studied. The main method of sample analysis was the atomic absorption spectrometry. There was determined the difference in concentrations of the same metal in different organs and in concentrations of different metals in the same organ, and also difference in the data about mature and immature groups. In general the pattern of heavy metals accumulation in sterlet organism is similar to that of other representatives of the family of sturgeon fishes and osteichthyes. The content of the all determined metals in the sterlet muscles in the Ob river middle course did not exceed the maximum permissible concentration accepted in Russia for fresh fish products.
