Occurrence of the cyanobacterial toxin cylindrospermopsin in northeast Germany [PDF]

Environmental Toxicology, 2007
AbstractThe frequent occurrence of the cyanobacterial toxin cylindrospermopsin (CYN) in the (sub)tropics has been largely associated with cyanobacteria of the order Nostocales of tropical origin, in particular Cylindrospermopsis raciborskii. C. raciborskii is currently observed to spread northwards into temperate climatic zones.

In Vitro Mutagenic and Genotoxic Assessment of a Mixture of the Cyanotoxins Microcystin-LR and Cylindrospermopsin [PDF]

, 2019
The co-occurrence of various cyanobacterial toxins can potentially induce toxic effects different than those observed for single cyanotoxins, as interaction phenomena cannot be discarded. Moreover, mixtures are a more probable exposure scenario. However,

Microcystins at the tap: A closer look at unregulated drinking water contaminants

AWWA Water Science, Volume 5, Issue 3, May/June 2023., 2023
Abstract This case study compared microcystins in tap water from 18 public water systems (PWSs) and 46 households with private intakes or nearshore wells (called self‐supplied water systems [SSWS]) from Clear Lake, California during a major cyanobacterial bloom in 2021. Microcystin concentrations were below the US EPA health advisory (HA; 0.3 μg/L) for

Dynamics of the Toxin Cylindrospermopsin and the Cyanobacterium Chrysosporum (Aphanizomenon) ovalisporum in a Mediterranean Eutrophic Reservoir

Toxins, 2014
Chrysosporum ovalisporum is a cylindrospermopsin toxin producing cyanobacterium that was reported in several lakes and reservoirs. Its growth dynamics and toxin distribution in field remain largely undocumented.

Neurotoxicity induced by microcystins and cylindrospermopsin: A review [PDF]

Science of The Total Environment, 2019
Microcystins (MCs) and cylindrospermopsin (CYN) are among the most frequent toxins produced by cyanobacteria. These toxic secondary metabolites are classified as hepatotoxins and cytotoxin, respectively. Furthermore, both may present the ability to induce damage to the nervous system.

Integrative monitoring strategy for marine and freshwater harmful algal blooms and toxins across the freshwater‐to‐marine continuum

Integrated Environmental Assessment and Management, Volume 19, Issue 3, Page 586-604, May 2023., 2023
Abstract Many coastal states throughout the USA have observed negative effects in marine and estuarine environments caused by cyanotoxins produced in inland waterbodies that were transported downstream or produced in the estuaries. Estuaries and other downstream receiving waters now face the dual risk of impacts from harmful algal blooms (HABs) that ...

Re‐evaluation of the risks to public health related to the presence of bisphenol A (BPA) in foodstuffs

EFSA Journal, Volume 21, Issue 4, April 2023., 2023
Abstract In 2015, EFSA established a temporary tolerable daily intake (t‐TDI) for BPA of 4 μg/kg body weight (bw) per day. In 2016, the European Commission mandated EFSA to re‐evaluate the risks to public health from the presence of BPA in foodstuffs and to establish a tolerable daily intake (TDI). For this re‐evaluation, a pre‐established protocol was

An Analytical Method for Simultaneous Measurement of Various Cyanotoxins Using Stable Isotope-Labeled Surrogates and a Microbial Flora Analysis to Assign Each Cyanotoxin to its Source

Journal of Water and Environment Technology, 2022
Cyanotoxins produced by blue-green algae in lakes are among the most serious threats to water quality worldwide. As global warming rapidly extends the locations and timing of blue-green algae blooms, a simple and accessible method for ...

Cylindrospermopsin: occurrence, methods of detection and toxicology [PDF]

Journal of Applied Microbiology, 2012
Cyanobacteria are aquatic micro-organisms that pose a great threat to aquatic ecosystems by the production of dense blooms, but most importantly by the production of secondary metabolites, namely the cyanotoxins. One of these is cylindrospermopsin (CYN), a hepatotoxic polyketide-derived alkaloid with well-known associated cases of animal mortalities ...

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the prospection of chemical hazards of interest in food safety in Spain (2)

Food Risk Assess Europe, Volume 1, Issue 1, March 2023., 2023
Abstract Throughout the food chain, various chemical hazards may be present, incorporated or produced, which may pose a risk to the consumer. In 2018, the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) reviewed the most relevant chemical hazards for food safety in Spain, which had no specific regulation, identifying ...
