Marine dinoflagellate species are often toxic, but freshwater species are not known to be toxic. Neither are diatoms known to be toxic, at least to humans. [33] In freshwater ecosystems, algal blooms are most commonly caused by high levels of nutrients (eutrophication). The blooms can look like foam, scum or mats or like paint floating on the ...
The health advisory for toxic algae remains in place at Detroit Lake, Big Cliff Reservoir and the North Santiam River. ... Subsequent tests have continued to show high levels of a cyanotoxin ...
Anatoxin-a, also known as Very Fast Death Factor (VFDF), is a secondary, bicyclic amine alkaloid and cyanotoxin with acute neurotoxicity.It was first discovered in the early 1960s in Canada, and was isolated in 1972.
Guanitoxin (GNT), formerly known as anatoxin-a(S) "Salivary" [a], [1] is a naturally occurring cyanotoxin commonly isolated from cyanobacteria (specifically of the genus Anabaena). It is a potent covalent acetylcholinesterase inhibitor, and thus a potent rapid acting neurotoxin which in cases of severe exposure can lead to death.
The expert panel tasked with finding ways to protect West Palm Beach’s water supply from cyantoxins is expected to issue a final report next month.
[41] [42] It is a cyanotoxin produced by at least four different genera of cyanobacteria, and has been reported in North America, Europe, Africa, Asia, and New Zealand. [75] Toxic effects from anatoxin-a progress very rapidly because it acts directly on the nerve cells .
(Reuters) -A Washington jury on Tuesday ordered Bayer to pay $100 million to four people who say they were sickened by toxic chemicals known as PCBs at a Seattle-area school, but found the company ...
Aetokthonotoxin (AETX), colloquially known as eagle toxin, is a chemical compound that was identified in 2021 as the cyanobacterial neurotoxin causing vacuolar myelinopathy (VM) in eagles in North America. [1]
