Environmental governance in the face of collapse: The case of Acapulco, Mexico, between tourist splendour and ecological risk

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Underwater clean‐up efforts in Acapulco Bay reveal the visible consequences of chronic coastal pollution. This study shows how Environmental Risk Assessments (ERAs) can integrate scientific evidence, regulatory frameworks and practitioner experience to identify pollution sources and guide more effective coastal governance in cities of the Global South.

Statewide Intensification of Harmful Algal Blooms Across California Lakes and Reservoirs

GeoHealth, Volume 10, Issue 4, April 2026.
Abstract Monitoring cyanobacteria is crucial for assessing water quality, safeguarding public health, and understanding ecosystem dynamics impacted by harmful algal blooms. This study explores the potential of satellite remote sensing (SRS) to assess risks of cyanotoxin exposure in California's recreational waters from 2002 to 2011 and 2016 to 2023 ...

Determination of saxitoxin by liquid chromatography/thermospray–mass spectrometry

, 1993
The determination of the paralytic shellfish poison saxitoxin by liquid chromatography/thermospray-mass spectrometry (LC/TS-MS) was investigated. It was found that a commercial sample contained an impurity, which was identified as the plasticizer tris(2 ...

A Synthesis of (+)-Saxitoxin

, 2016
An asymmetric synthesis of the bis-guanidinium poison, (+)-saxitoxin (STX), is described. Commencing from an N,O-acetal starting material made readily available through sulfamate ester C−H amination, the completed route to STX showcases the utility of ...

Oral Chronic Toxicity of the Safe Tetrodotoxin Dose Proposed by the European Food Safety Authority and Its Additive Effect with Saxitoxin

Toxins, 2020
Tetrodotoxin (TTX) is a potent natural toxin causative of human food intoxications that shares its mechanism of action with the paralytic shellfish toxin saxitoxin (STX). Both toxins act as potent blockers of voltage-gated sodium channels. Although human

Influence of environmental variables on saxitoxin yields by Cylindrospermopsis raciborskii in a mesotrophic subtropical reservoir

, 2017
Saxitoxins are a class of toxins produced by at least two groups of evolutionarily distant organisms (cyanobacteria and dinoflagellates). While the toxicity of these toxins is relatively well characterized, to date little is known about their drivers and
