The heavy metal concentrations in different algae species were reviewed after collection from Black Sea and Bosphorus stations from 1979 to 2001. The results showed that the Turkish Black Sea coast and Bosphorus region faced heavy metal pollution. However, Cd, Co, Cr and Pb levels were found to be below lower limit detection in all tested Black Sea algae species collected in 1998 and 1999. On the other hand, Cd, Cr, Cu, Ph and Zn concentrations increased at the eastern Black Sea stations in 2001. As a result, it can be said that the heavy metal monitoring of marine algae species with reperesentative sampling sites along the Bosphorus and Black Sea Turkish Coast should be continued.
