Description
Summary:	Cyanotoxin contamination is of special interest in water bodies, especially those for human use, due to the various negative effects that blooms of potentially toxic cyanobacteria can cause on human health. Given the recreational and supply importance of the Abreo - Malpaso, Peñol - Guatapé and Playas reservoirs in the Department of Antioquia, Colombia. This study has estimated the biomass of the planktonic cyanobacteria, their geometric biovolume, the surface volume ratio (S / V) and the maximum linear dimension (MLD), during four sampling seasons in three different stations for each of these bodies. Water. We have identified from the Cyanophyta division with the production of cyanotoxins, the Microcystis complex and generates Woronichinia, Aphanocapsa and Oscillatoria, as well as the species Radiocystis fernandoi. When applying the nonparametric Kruskal - Wallis test, no significant differences were found between the studied reservoirs (p> 0.05); however, the Peñol - Guatapé reservoir presented the highest algae biomass and density of cyanobacteria, therefore, according to the levels of risk posed for the reservoirs studied and according to the morphological characteristics of these organisms, this reservoir presents a High Medium risk level in relation to the presence and morphology of the cyanobacteria, while the Abreo-Malpaso and Playas reservoirs are associated with a Medium Low risk. It is suggested to establish control and prevention measures to avoid a massive development of cyanobacteria, a possible presence of cyanotoxins and serious affectations in humans and animals.
