Abstract: Cyanotoxins produced by the toxic cyanobacteria is a great threat to global freshwater ecosystems, with hepatotoxic microcystins (MCs) as the most widely distributed and harmful ones. MCs have negative impacts on the structure, function and stability of aquatic ecosystems, posing threats to human health. In this study, we reviewed the distribution of MCs in waterbody, sediments, and different groups of aquatic animals. The toxicity mechanisms of MCs were also reviewed. The ecotoxicological effects of MCs on aquatic animals, aquatic and terrestrial plants, human health risk were summarized. Several biological methods about the prevention and control of MCs were mentioned. Many aspects about MCs that need to be further studied were proposed, aiming to provide a scientific basis for risk assessment and management of MCs.

Key words: microcystins, aquatic environment, aquatic animal, plant, toxicological effect.
