Особенности накопления и корреляции тяжелых металлов в костной ткани судака Новосибирского водохранилища

The paper provides the data about characteristics in accumulation of iron, copper, manganese, zinc, cadmium and lead and their correlation in the bone tissue of zander, Stizostedion lucioperca, in Novosibirsk water basin. The heavy metals concentration was determined for GOST 30178-96 (State Standard) with the method of atomic absorption spectrometry. Zink (83,89±1,10 mg / kg) and iron (25,25±1,55mg / kg) dominate for the amount of heavy metals in bone. It was established that iron, manganese concentrations were 2.5 and 1.2 times greater in zander scales in Novosibirsk water basin than those in bone and copper and zink concentration were 4.4 and 1.2 times greater in zander bone than those in scales, respectively. In a muscle tissue, compared with bone tissue, the content of iron is bigger in 1,73 times, content of lead is approximately the same. High positive correlations between the content of iron and lead, iron and copper were revealed. The microelements content in the bone tissue of Stizostedion lucioperca from Novosibirsk water basin goes down in the following range: Zn>Fe>Mn >Cu and Pb>Cd. Mean population values of heavy metals were established in zander bone in Novosibirsk water basin and they can be used in ecology, veterinary, zootechnology when evaluating zander interior for elemental composition.
