Trace element content of marine algae species collected from the Black Sea coasts were determined by atomic absorption spectroscopy after microwave digestion. Trace element content in marine algae species were 1.70-17.1 mu g/g for copper, 3.64-64.8 mu g/g for zinc, 9.98-285 mu g/g for manganese, 99-3,949 mu g/g for iron, 0.50-11.6 mu g/g for chromium, 0.27-36.2 mu g/g for nickel, 11-694 mu g/kg for selenium, 0.50-44.6 mu g/kg for cadmium, 1.54-3,969 mu g/kg for lead, 1.56-81.9 mu g/kg for cobalt. While iron was the highest trace element concentration, cadmium was the lowest in samples. Most of the analyzed samples were edible. The samples are consumed for human diet in several countries.
