GOMEZ LUNA, Liliana M; ALAMO DIAZ, Beatriz  and  RODRIGUEZ TITO, José Carlos. Risk of pollution with cyanobacteria in three water reservoirs of Santiago de Cuba. MEDISAN [online]. 2010, vol.14, n.2. ISSN 1029-3019.

The risk of pollution with cyanobacteria is undoubtedly an important topic of great social impact. It is very well-known the relation between the flowering of these microorganisms and the serious involvement to the human health. With the purpose of proposing an administration model of the risk of pollution with cyanobacteria in water reservoirs for the human consumption, the presence of these bacteria was studied in 3 reservoirs (Chalóns, Paradas and Charco Mono), which supply more than 80 % of Santiago population, from November, 2008 to March, 2009. Qualitative and quantitative samplings were made to characterize the phytoplankton and determine its density, which ranged between 5 and 25x104 cel/mL-1. Seventy three species of phytoplankton and nine cyanobacteria potentially toxic were identified. This study contributes to the design of a methodology to face these risks of pollution.

Keywords : cyanobacteria; cyanotoxins; waterweed flowering; reservoirs; eutrophyzation phytoplankton.
