Content of heavy metals in algae thalli in the littoral zone of Kildin Island (Barents Sea)

Abstract

The article examines the concentration of four heavy metals (cadmium, lead, copper and zinc) in three species of brown and three species of red algae ((Fucus vesiculosus L., Alaria esculenta (L.) Greville, Chorda filum (L.) Stackhouse, (Delesseria sanguinea (Hudson) J.V.Lamouroux, Palmaria palmata (L.) F.Weber & D.Mohr, Ptilota plumosa - (L.) C. Agardh.), living in the waters of the Barents Sea in the littoral zone of Kildin Island. It is shown that the highest concentrations. are found for essential metals (copper and zinc), lower for non-essential metals. The maximum content of zinc and copper was observed in palmaria and ptilote, the minimum in chord. The maximum of lead and cadmium was found in fucus, the minimum in chord.
