CHACTERISTIC FEATURES OF HEAVY METALS ACCUMULATION AND CORRELATION IN THE LIVER OF ZANDER FROM NOVOSIBIRSK WATER BASIN
Characteristic features were studied in the accumulation of iron, copper, zinc, manganese and their correlations in the liver of zander (Stizostedion lucioperca) from Novosibirsk water basin. Concentrations of heavy metals were determined by atomic emission spectral method with excited spectra in two-jet-stream arc plasma (TAP-AES). Iron (173,0 ± 15,97 mg / kg) and zinc (66,27 ± 4,18 mg / kg) dominate for the amount of heavy metals in liver. It was established that iron, copper concentrations were 3,59 and 5.0 times greater in zander liver in Novosibirsk water basin than those in scales, respectively. High positive correlations between the content of iron and copper, zinc, manganese were revealed. The content of Mn, Cu, Zn, Fe were in the ratio 1: 1,2: 16,4: 42,9, respectively. Mean population values of heavy metals were established in zander liver in Novosibirsk water basin.
