| Abstract: | The Sc and lanthanides Ce, La and Sm contents of 17 representatives of the Bulgarian flora that belong to 4 sections, 15 families and 16 genera from Black Sea region have been studied. Twelve kinds of algae are investigated, nine of them being part of the Black Sea macrobentos, and the remaining three, of the freshwater flora in rivers running into Bourgas gulf of the Black Sea. Five kinds of flowering plants were investigated. Three of them (psamophytes) are found in coastal sands, whereas the other two belong to freshwater and seawater flora. |
