Abstract: Hepatotoxic cyclic peptides and neurotoxic alkaloids are the most common groups of cyanobacterial toxins. They pose a serious threat to human and animal health; each year they are responsible for several cases of animal fatalities (mammals, fish and birds). In Polish water bodies toxic blooms of cyanobacteria are also frequently observed. In this work, a procedure for anatoxin-a analysis has been modified to obtain a sensitive and selective method for routine studies of bloom samples. The presence of cyanobacterial neuro and hepatotoxins in fresh and brackish waters of Pomorskie Province was examined. Hepatotoxins, microcystins or nodularin, were detected in all phytoplankton samples dominated by the cyanobacteria of Microcystis and Anabaena genera or by Nodularia spumigena. HPLC-PDA analysis showed the presence of anatoxin-a only in one sample collected in coastal waters of the Gulf of Gdańsk and dominated by Anabaena.
