Algal Neurotoxin Lingers In The Ocean

Domoic acid, which causes environmental and human health problems, is more persistent in global oceans than previously thought
Department: Science & Technology

A neurotoxin called domoic acid produced by marine algae can spread farther and is more persistent in global oceans than previously thought, according to a study in Nature Geoscience (DOI: 10.1038/ngeo472). Seasonal blooms of Pseudo-nitzschia phytoplankton produce large amounts of domoic acid, which can cause digestive difficulties and short-term memory loss in people who ingest it in seafood. It's also linked to die-offs of sea lions, whales, and marine birds and was linked to the . . .
