Abstract
The concentrations of heavy metals (Cu, Ni, Co, Ti, and Cr) and boron in the Azov and the Black Seas water near the Kerch Strait are considered. The copper, nickel and cobalt concentrations were obtained to exceed MPC both for Azov and Black Sea waters. Calculated heavy metals fluxes from the Sea of Azov on the average exceeded ones from the Black Sea through the Strait. These values were calculated for different rates of water exchange between the Black Sea and the Sea of Azov. The Sea of Azov was shown to be the source of heavy metals and boron contamination for the Black Sea ecosystem.
