“…MC-producing Microcystis blooms have been reported in European brackish waters (Rocha et al, 2002;Karlsson et al, 2005;Verspagen et al, 2006) and a bloom of M. aeruginosa has been recorded from the Minho River estuary (Portugal) that contained MC-LR (MC with leucine and arginine) and another variant of MC that is as yet uncharacterized (Vasconcelos & Cerqueira, 2001). In the Guadiana estuary (Portugal) the presence of MCs has also been reported, produced either by Microcystis or Oscillatoria species (Sobrino et al, 2004).…”

“…E-mail: vmvascon@ fc.up.pt Tan, 2007). The cyanobacteria of brackish waters (including estuaries), however, remain under-investigated, particularly in Europe, despite a number of significant contributions (Sivonen et al, 1989;Nehring, 1993;Lehtima¨ki et al, 1994Lehtima¨ki et al, , 1997Lehtima¨ki et al, , 2000Wille´n & Mattson, 1997;Sivonen & Jones, 1999;Sipia¨et al, 2001Sipia¨et al, , 2002Sipia¨et al, , 2006Sipia¨et al, , 2007Sipia¨et al, , 2008Vasconcelos & Cerqueira, 2001;Laamanen et al, 2002;Rocha et al, 2002;Geiss et al, 2003;Hobson & Fallowfield, 2003;Lehtonen et al, 2003;Stal et al, 2003;Sobrino et al, 2004;Herfindal et al, 2005;Kankaanpa¨a¨et al, 2005;Karjalainen et al, 2005Karjalainen et al, , 2007Karlsson et al, 2005;Pere´z & Carrilo, 2005;Surakka et al, 2005;Marino et al, 2006;Mazur-Marzec et al, 2007Paoli et al, 2007;Halinen et al, 2008;Ibelings & Havens, 2008;Jo´z´wiak et al, 2008;Lopes et al, 2010;Oftedal et al, 2010;).

“…Hepatotoxins are the main toxins found so far, being produced by planktonic Nodularia spumigena, Microcystis sp., Nostoc sp., Planktothrix sp., Phormidium sp. and some Anabaena species (Vasconcelos & Cerqueira, 2001;Rocha et al, 2002;Sobrino et al, 2004;Karlsson et al, 2005;Halinen et al, 2007).…”

Planktonic and benthic cyanobacteria of European brackish waters: a perspective on estuaries and brackish seas

Cyanobacteria are photosynthetic organisms found in aquatic and terrestrial biotopes and ecosystems throughout the world. Marine and freshwater cyanobacteria have been extensively studied due to the toxic hazards that some of them create and biotechnological interest. In contrast, the cyanobacteria of brackish waters have been less studied despite being able to form toxic blooms like their freshwater and marine counterparts. We review the occurrence, diversity and toxicity of cyanobacteria species in the brackish waters of Europe, mainly estuaries and brackish environments of the Atlantic Ocean and the Mediterranean and Baltic Seas. The dominant cyanobacteria belong mainly to the planktonic genera Nodularia, Aphanizomenon, Microcystis and Anabaena, but also the benthic forms of Anabaena and Phormidium. Most genera from brackish waters are reported to be hepatotoxin producers (microcystin and nodularin). However, anatoxin-a and other bioactive compounds (e.g. apoptogens) can also be found and are produced exclusively by benthic forms. Nodularin is the best-characterized brackish-water cyanotoxin, being primarily produced by N. spumigena. Data are presented on cyanotoxin production, accumulation, and potential food chain transfer, with a particular focus on nodularin, which induces multiple effects on food-chain dynamics. Microcystins and anatoxin-a are also considered. Potential risks to animals and humans from cyanotoxin exposure are discussed, although reports of animal poisoning by brackish-water toxic cyanobacteria are scarce and no cases of human intoxication are yet known.

“…The negative effects, among others, are attributed to the occurrence of hepatotoxin producing N. spumigena. The toxin called nodularin (NOD) accumulates in Baltic fish, mussels and waterfowl (Sipiä et al, 2001;Karlsson et al, 2005;Kankaanpää et al, 2005;Kankaanpää et al, 2007). In the past, several cases of poisoning of terrestrial and aquatic animals following contact with N. spumigena were recorded (Francis, 1878;Edler et al, 1985;Nehring, 1993).…”

Occurrence of cyanobacteria and cyanotoxin in the Southern Baltic Proper. Filamentous cyanobacteria versus single-celled picocyanobacteria

et al. 2012

In the Baltic Sea, cyanobacterial community is mainly composed of filamentous nitrogen-fixing forms, including the toxic Nodularia spumigena, and single-celled picocyanobacteria (Pcy), represented by Synechococcus spp. The main aim of the work was to test the hypothesis that the picocyanobacteria dependend on the presence of the nitrogen-fixing cyanobacteria. In addition, the contamination of blue mussels and fish with nodularin (NOD), the N. spumigena toxin, was examined. In years 2008-2011, the samples for the study were collected in the Southern Baltic Proper using FerryBox system and, occasionally, during research cruises. The analyses showed no correlation between the growth of the nitrogen-fixing cyanobacteria and Synechococcus. Compared with the previously published data, a shift in the composition of Pcy phenotypes was observed. This shift might be an indication of the proceeding changes induced by the reduced nutrient loading and/or climate change. Analyses of NOD revealed differences in the cyanotoxin concentrations between mussels of different shell size. The highest concentration of NOD was detected in the liver of round goby. However, temporarily, also the fish muscles were significantly contaminated with the toxin.

“…A faster and cheaper method could therefore be useful for screening purposes, so that the number of samples for LC-MS/MS analysis can be reduced. In microcystin research, ELISA kits are frequently used for fast and sensitive analyses (e.g., [205][206][207]) and in 2012, an ELISA for BMAA detection became commercially available. However, this assay showed high cross reactivity in a diversity of sample types, and should be further developed before application (Chapter 4).…”
