“…In the Tyrrhenian and Ligurian Seas (western MS), benthic mucilages have occurred since 1991 (Sartoni and Sonni, 1991), and have been attributed to the massive growth of several macro-and microalgae such as the filamentous brown alga Acinetospora crinita and the colonial pelagophytes Nematochrysopsis marina and Chrysonephos lewisii (Giuliani et al, 2005;Schiaparelli et al, 2007). The allochthonous pelagophyte Chrysophaeum taylorii, recorded in the western MS since 2005, in recent years was involved in the formation of dense layers of mucous covering macroalgae, gorgonians and the surrounding rocks (Lugliè et al, 2008;Caronni et al, 2015).…”

“…Whereas dinoflagellates and diatoms are found primarily in marine environments, cyanobacteria are usually considered the major HAS in freshwater ecosystems. Actually, their impacts on transitional aquatic ecosystems may increase due to global climatic change [61]. Cyanobacteria produce an impressive range of toxic secondary metabolites, the cyanotoxins, whose presence and concentration in the waters is both a relevant threat to human health and the environment and a substantial economic cost [62,63].…”

The prevalence of neurodegenerative disease (ND) is increasing, partly owing to extensions in lifespan, with a larger percentage of members living to an older age, but the ND aetiology and pathogenesis are not fully understood, and effective treatments are still lacking. Neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis are generally thought to progress as a consequence of genetic susceptibility and environmental influences. Up to now, several environmental triggers have been associated with NDs, and recent studies suggest that some cyanotoxins, produced by cyanobacteria and acting through a variety of molecular mechanisms, are highly neurotoxic, although their roles in neuropathy and particularly in NDs are still controversial. In this review, we summarize the most relevant and recent evidence that points at cyanotoxins as environmental triggers in NDs development.

“…Their presence is not yet linked to human food safety, although some of these toxins are common to dinoflagellates. 13 Palytoxin has been reported to be produced by Trichodesmium spp., 14,15 lyngbyatoxins (similar to teleocidins from Streptomyces) are produced by Moorea producens (formerly Lyngbya majuscula), 16 nodularins are produced by Nodularia spumigena, 13 microcystins are produced by Leptolyngbya or Geitlerinema, 17 saxitoxins are produced from Raphidiopsis bookii, 18,19 and BMAA may be produced by many cyanobacteria strains, especially Nostoc. 13 Although some of these compounds may reach humans by consumption of fish or shellfish, 13 this is not common.…”

In recent years, our group and several others have been describing the presence of new, not previously reported, toxins of high toxicity in vectors that may reach the human food chain. These include tetrodotoxin in gastropods in the South of Europe, ciguatoxin in fish in the South of Spain, palytoxin in mussels in the Mediterranean Sea, pinnatoxin all over Europe, and okadaic acid in the south of the U.S. There seem to be new marine toxins appearing in areas that are heavy producers of seafood, and this is a cause of concern as most of these new toxins are not included in current legislation and monitoring programs. Along with the new toxins, new chemical analogues are being reported. The same phenomenom is being recorded in freshwater toxins, such as the wide appearance of cylindrospermopsin and the large worldwide increase of microcystin. The problem that this phenomenon, which may be linked to climate warming, poses for toxicologists is very important not only because there is a lack of chronic studies and an incomplete comprehension of the mechanism driving the production of these toxins but also because the lack of a legal framework for them allows many of these toxins to reach the market. In some cases, it is very difficult to control these toxins because there are not enough standards available, they are not always certified, and there is an insufficient understanding of the toxic equivalency factors of the different analogues in each group. All of these factors have been revealed and grouped through the massive increase in the use of LC-MS as a monitoring tool, legally demanded, creating more toxicological problems.
