Abstract

The environmental global change increases the proliferation of cyanobacteria and the release of very dangerous cyanotoxins in water reservoirs, both for supply and recreation. These cyanotoxins may be very harmful, so it is necessary to increase control, especially in recreational bathing waters, to avoid undesirable events in the population.  Cyanobacteria and cyanotoxins were analyzed in samples from water columns and the surface of the bathing areas which are authorized by the Community of Madrid, as well as in water reservoirs for humanconsumption. Sampling was carried from May to October of 2018. In each site at least 2 samples werecollected at different times.  With the exception of Presillas Beach (Rascafria), in the sampled sites cyanotoxins-producer cyanobacteria were detected, as well as microcystin levels higher than 1μg/L. Microcystin concentration and cyanobacteria peaks occurred within the months of July and August. The study confirms that there is presence of microcystins in recreational waters within the bathingperiod. It is necessary to establish cyanotoxins controls using a warning system for the appearance of toxic blooms in recreational waters.
