Model predicts coastal paralytic shellfish toxicity in mussels from in situ phytoplankton concentrations. [PDF]

Limnol Oceanogr
Abstract Harmful algal blooms (HABs) of Alexandrium catenella occur annually in the Gulf of Maine, leading to accumulation of paralytic shellfish toxins (PSTs) in bivalve mollusks and closure of harvesting areas. State monitoring programs in the region rely on weekly shellfish sampling and toxin analysis, requiring extensive effort with limited ...

Occurrence and Diversity of Cyanotoxins and Retinoid Compounds in Antarctic Microbial Mats: Evidence From James Ross Island. [PDF]

Environ Microbiol Rep
Occurrence and distribution of cyanotoxins and retinoids across different Antarctic ecosystems at James Ross Island. These ecosystems harbour diverse microbial communities dominated by autotrophic cyanobacteria and algae, which can produce hazardous compounds for animals.

Photochemical Reactivity of Dissolved Organic Matter: Implications for the Environmental Fate and Engineered Removal of Saxitoxins [PDF]

Dissolved organic matter (DOM) is a fundamental component of natural aquatic systems that influences processes such as nutrient cycling, primary productivity through the attenuation of light, indirect photochemical transformations of contaminants, and ...

A Stereocontrolled Synthesis of (+)-Saxitoxin [PDF]

Journal of the American Chemical Society, 2011
A concise stereoselective total synthesis of (+)-saxitoxin is described. A silver(I)-initiated hydroamination cascade constructs the bicyclic guanidinium ion core from a alkynyl bisguanidine. This sequence creates two C-N bonds, one C-O bond, and three rings and forms a single stereoisomer in a single synthetic transformation.

Semiquantitation of Paralytic Shellfish Toxins by Hydrophilic Interaction Liquid Chromatography-Mass Spectrometry Using Relative Molar Response Factors

Toxins, 2020
Paralytic shellfish toxins (PSTs) are a complex class of analogs of the potent neurotoxin saxitoxin (STX). Since calibration standards are not available for many PSTs, including C-11 hydroxyl analogs called M-toxins, accurate quantitation by liquid ...

First Toxicological Analysis of the Pufferfish Sphoeroides pachygaster Collected in Italian Waters (Strait of Sicily): Role of Citizens Science in Monitoring Toxic Marine Species

Animals, 2023
Pufferfish (Tetraodontidae) inhabiting the Mediterranean Sea may represent an emerging public health risk due to the possible accumulation of marine neurotoxins such as tetrodotoxin (TTXs) and saxitoxin (STXs) in their tissues.
