Occurence of toxic algal bloom of Microcystis ichtyoblade in Corumana Reservoir, Mozambique, Africa.

The high levels of microcystins observed raise concerns about the possible effects of the toxins on the health of the local people who are in their life time drinking water from this lake. [...] The result of the present study might be a contribution to the knowledge of the biogeography of toxic cyanobacteria in African countries, but also raise the need to extend the cyanobacterial education to elucidate the water managers and local the people how to handle the situation when this kind of phenomenon occurs. [...] View of Algal Bloom at Corumana Reservoir Background When an algal bloom appeared for the first time in Corumana In recent years, during some periods of the year blooms of Reservoir in 2009 and, subsequently, in 2011 attracted attention cyanobacteria composed mainly by the genus Microcystis appeared from the water managers and people in the local community and more frequently in the plankton of se. [...] of 2009 microcystin varied from 460 to 550 µg/l and in To understand the impact of these bloom to the local community 2011varied from 46 to 5500 µg/l. [...] Cyanobacteria and cyanotoxins in the source water from Lake Chivero, Harare, Zimbabwe, and the presence of cyanotoxins in drinking water.
