The first report of microginins isolated from cyanobacteria of Greek lakes was published by Zervou et al. in Chemosphere. As many as 36 new structures of microginins were elucidated with MS/MS techniques. The work was supported by a CYANOCOST STSM grant of Sevasti Zervou (NCSR Demokritos) to Hanna Mazur-Marzec (University of Gdansk).

The combination of liquid chromatography with mass spectrometry (LC-MS) is a valuable tool for the determination of algal toxins contained at trace levels in complex matrices thanks to its high sensitivity, selectivity and ability to deal with the structural diversity and labile nature of the toxins. Targeted LC tandem MS (LC-MS/MS) approaches are already efficiently employed worldwide to monitor toxin distribution in the environment and in the food chain. At the same time, untargeted approaches based on high resolution MS (LC-HRMS) have generally disclosed the presence of a much higher number and types of toxins and made straightforward elucidation of the gross structure of the unknowns based on the interpretation of their fragmentation patterns.
In view of the plethora of LC-MS/MS and LC-HRMS methods that have been developed so far, the need exists for critical reviews that, besides summarizing the methodologies for determination of each toxin-group, single out the main challenges to be addressed in the next future for marine, freshwater and fish-killing toxins. Collaborative efforts among scientists are strongly encouraged both in the field of the regulated toxins in EU and the emerging ones to build the rational basis for inter-laboratory validation trials, where needed. Original research articles reporting LC-MS based identification of emerging issues for water and food safety potentially associated with climate change as well as recent advancements in LC-MS data acquisition and treatment (On-line SPE-LC-MS, 2D-LC-MS, Metabolomics, among others) will be also included in this Special Issue.
