SoundToxins: A Research and Monitoring Partnership for Harmful Phytoplankton in Washington State

Toxins, 2023
The more frequent occurrence of marine harmful algal blooms (HABs) and recent problems with newly-described toxins in Puget Sound have increased the risk for illness and have negatively impacted sustainable access to shellfish in Washington State. Marine

The value of toxin profiles in the chemotaxonomic analysis of paralytic shellfish toxins in determining the relationship between British Alexandrium spp. and experimentally contaminated Mytilus sp.

, 2021
Although phytoplankton is ubiquitous in the world's oceans some species can produce compounds that cause damaging effects in other organisms. These include the toxins responsible for paralytic shellfish poisoning, which, in UK waters, are produced by ...

Determination of Gonyautoxin-4 in Echinoderms and Gastropod Matrices by Conversion to Neosaxitoxin Using 2-Mercaptoethanol and Post-Column Oxidation Liquid Chromatography with Fluorescence Detection

Toxins, 2015
Paralytic Shellfish Toxin blooms are common worldwide, which makes their monitoring crucial in the prevention of poisoning incidents. These toxins can be monitored by a variety of techniques, including mouse bioassay, receptor binding assay, and liquid ...

Tetrodotoxin and paralytic shellfish toxins in Philippine crabs.

Agricultural and Biological Chemistry, 1986
The frequent occurrence of lethal specimens of Zosimus aeneus and Atergatis floridus on southern Negros Island, Philippines, was confirmed by mouse lethality tests. Among eight specimens of Z. aeneus analyzed by fluorometric liquid chromatography, tetrodotoxin and its derivatives were dominant in five indicating the possible involvement of tetrodotoxin

Effects of Two Toxin-Producing Harmful Algae, Alexandrium catenella and Dinophysis acuminata (Dinophyceae), on Activity and Mortality of Larval Shellfish

Toxins, 2022
Harmful algal bloom (HAB) species Alexandrium catenella and Dinophysis acuminata are associated with paralytic shellfish poisoning (PSP) and diarrhetic shellfish poisoning (DSP) in humans, respectively.

C–H Hydroxylation in Paralytic Shellfish Toxin Biosynthesis [PDF]

Journal of the American Chemical Society, 2018
The remarkable degree of synthetic selectivity found in Nature is exemplified by the biosynthesis of paralytic shellfish toxins such as saxitoxin. The polycyclic core shared by saxitoxin and its relatives is assembled and subsequently elaborated through the installation of hydroxyl groups with exquisite precision that is not possible to replicate with ...

Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high
