Abstract

The levels of heavy metal accumulation and chemical composition of Cladophora dalmatica and Ceramium ciliatum var. robustum were analyzed in this investigation. The samples were collected at Yeni Sakran Bay at the north side of the gulf of Izmir. It was found that the amounts of water, protein and fats of C. ciliatum var. robustum were, higher than in Cl. dalmatica, grown in the same environment. The contents c i ash, P, K and Ca were higher in Cl. dalmatica than in C. ciliatum var. robustum. while the contents of Na and Mg of C. ciliatum var. robustum were higher than in Cl. dalmatica. Although Fe, one of the heavy metals, accumulated similarly in both algae, Cu and Zn levels were higher in Cl. dalmatica, while Mn level higher in C. ciliatum var. robustum. The accumulation of the heavy metals was ranked as Fe>Zn>Mn>Cu, for both groups. Additionally, the physico-chemical parameters of environmental water were determined.
