Certain marine algae produce potent toxins that impact human health through the consumption of contaminated shellfish and finfish and through water or aerosol exposure. Over the past three decades, the frequency and global distribution of toxic algal incidents appear to have increased, and human intoxications from novel algal sources have occurred. This increase is of particular concern, since it parallels recent evidence of large-scale ecologic disturbances that coincide with trends in global warming. The extent to which human activities have contributed to their increase therefore comes into question. This review summarizes the origins and health effects of marine algal toxins, as well as changes in their current global distribution, and examines possible causes for the recent increase in their occurrence.

Neurotoxic Alkaloids: Saxitoxin and Its Analogs (2010, positive): “The PSTs are primarily produced in detrimental concentrations during harmful algal bloom (HAB) events [2–5] Over the last few decades, HABs have become more frequent, intense, and span a wider global distribution, the cause of which is still under debate [3,6].”
Predicting potentially toxigenic Pseudo-nitzschia blooms in the Chesapeake Bay (2010, positive): “…eutrophication, is now considered an important factor driving the global increase in HAB itzschia blooms in the Chesapeake Bay, J. Mar. Syst. frequency and intensity (Hallegraeff, 1993; VanDolah, 2000; Anderson et al., 2002; Glibert et al., 2005; Heisler et al., 2008; Anderson et al., 2008).”
Deep whole-genome resequencing sheds light on the distribution and effect of amphioxus SNPs (2022, neutral): “Ion channels are the targets of many algal toxins [31], hence related genes inevitably suffer from high selective pressure, meanwhile their immune system and digestive system have to maintain active almost all the time.”
The Effects of Harmful Algal Blooms on Aquatic Organisms (2002, neutral): “The ecological role of these byproducts and the apparent increase in toxic species or strains around the world has been much discussed (e.g., Van Dolah, 2000, and references therein).”
Can increases in temperature stimulate blooms of the toxic benthic dinoflagellate Ostreopsis ovata (2011, background): “There is near unanimous scientific consensus that the world may be entering a period of global warming in response to atmospheric greenhouse gas accumulation generated due to human activities (Van Dolah, 2000).”
Is Marine Mammal Health Deteriorating? Trends in the Global Reporting of Marine Mammal Disease (2007, positive): “This reflects a true increase in the frequency of harmful algal blooms around the U.S., especially over the last decade (Van Dolah, 2000).”
