Toxic metabolites of bluegreen algae and detection methods

Abstract

The review considers a variety of structural variants of cyanotoxins, their physical and chemical properties, the mechanisms of toxic effects, methods of determination in environmental objects. Cyanobacteria produce secondary metabolites; which could be highly toxic to humans and animals. Since the 2000s cyanobacterial blooms have been commonly reported in Russia. The domination of more then 20 potentially toxic cyanobacterial species of genera Aphanizomenon, Dolichospermum, Planktothrix, Microcystis was documented in most of examined Russian water bodies. For freshwater reservoirs, highly toxic neurotoxins (anatoxin-a, anatoxina( s) and saxitoxins) and widespreaded microcystins are the most dangerous. Refs 186. Figs 4. Tables 3.
