Content of Ni, Pb and Zn, in selected elements of ecosystem in three bays in the area of Sevastopol

Abstract

The aim of the study was to evaluate the content of Ni, Pb and Zn in the water and larvae of fish of the genus Atherinidae L., caught in three bays in the area of Sevastopol. The study was conducted in 2012 in the three bays in the area of Sevastopol: Galubaya, Omega and Karantinna. The results indicate that the content of all elements studied was at a higher level than that observed in the uncontaminated basins. The average concentration of Ni, Pb and Zn in water was respectively: 1.199; 14.62 and 64.32 μg · dm-3. The content of the elements studied in the examined fish larvae Atherinidae ranged from 6.413 to 19.65 mg Ni kg -1, from 1.749 to 5.393 mg Pb kg -1 and from 97.16 to 215.24 mg Zn kg-1.
