Abstract

The cyanobacterial cytotoxin cylindrospermopsin has been mostly associated with cyanobacteria present in tropical and subtropical regions. Cylindrospermopsin has recently been found in cyanobacterial samples in central and southern Europe but the possible presence of the toxin in northern Europe has been unknown. Fifty-eight field and laboratory culture samples of Finnish cyanobacteria were analyzed by high-performance liquid chromatography combined with UV diode-array detection, multiple reactant monitoring in a triple-quadrupole mass spectrometer (MS), and accurate mass measurements using a time-of-flight MS instrument. Cylindrospermopsin was confirmed by all three techniques in a culture sample of Anabaena lapponica at a concentration of 242 μg cylindrospermopsin per g freeze-dried cyanobacterial material.
