Most marine toxins are a structurally and toxicologically diverse group of secondary metabolites produced by dinoflagellates and diatoms or bacteria (tetrodotoxins). They are nonproteinacious and heat-stable compounds responsible for a series of human poisonings caused by contaminated seafood consumption or by seawater/aerosol exposure, but also for marine mammals and birth moribidity/mortality, and fish kills. As a consequence of ecological changes from anthropogenic activities, such as increased eutrophication, marine transport, and climate changes favouring the proliferation of toxic microalgae, the risks from marine toxins had increased in the last decades.

Abstract
Most marine toxins are a structurally and toxicologically diverse group of secondary metabolites produced by dinoflagellates and diatoms or bacteria (tetrodotoxins). They are nonproteinacious and heat-stable compounds responsible for a series of human poisonings caused by contaminated seafood consumption or by seawater/aerosol exposure, but also for marine mammals and birth moribidity/mortality, and fish kills. As a consequence of ecological changes from anthropogenic activities, such as increased eutrophication, marine transport, and climate changes favouring the proliferation of toxic microalgae, the risks from marine toxins had increased in the last decades. This chapter summarizes the chemical, biological, toxicological and regulatory aspects of the most dangerous or common marine toxins.Pubblicazioni consigliate
