【 摘 要 】

The content of iron, zinc, copper, manganese, lead and cadmium has been studied in vastus muscle of the zander from Novosibirsk water basin upstream waters. The ranged row of the chemical elements levels was as follows: Fe>Zn>Cu>Mn>Pb>Cd. The concentration of all the elements, except for iron, did not exceed maximum permissible concentrations (MPC). The content of iron in zander muscles was 1.06 times higher than MPC. For the past 17 years, concentrations of heavy metals such as Cd, Fe, Zn, Mn and Pb in zander muscles decreased several times as much. It was determined that correlations among chemical elements in zander muscles were different in value and direction.
