Considerable accumulations of blue-green algae, with a dominance of the potentially toxic Nodularia spumigena, are present in the Baltic Sea. Most algal mats around Gotland. Less, but still a lot in the Hanö Bight and in the south part of Öresund. With sunny and calm weather the blooms will continue. Along Bohuslän on the west coast there are large accumulations of the harmless dinoflagellate Noctiluca scintillans in certain bays, coloring the water light red. All along the coast the potentially toxic dinoflagellates Dinophysis, which contain a diarrhoea toxin, is present in relatively low concentrations.
