Abstract Cyanobacterial blooms in drinking water supply affect its quality, which ultimately impacts ecosystem and public health. Thus, this cross-sectional study was conducted to perform a preliminary on cyanotoxins via analysis of samples collected only once from two sites during the month peak algal bloom subsequently prompt comprehensive risk assessment major source, Legedadi Reservoir, Add...

Abstract Background Excess loads of nutrients finding their way into waterbodies can cause rapid and excessive growth phytoplankton species lead to the formation cyanobacterial harmful algal blooms (cyano-HABs). Toxic cyanobacteria produce a broad range bioactive metabolites, some which are known as cyanotoxins. These metabolites negatively impact ecosystem, human animal health, thus presence n...

this study aimed to develop techniques for purification of cyanotoxins dissolved in water -particularly those produced by microcystis aeruginosa species - using natural clay, chemically modifiednatural clay, commercial clay and ion exchange and adsorbent resins. except for natural clay, chemical pretreatment was required to increase the adsorption capacity of the treatment materials. all the cl...

To determine the direct effects of microcystin on the fitness of herbivorous zooplankton, we experimentally added microcystin-LR to freeze-dried cells of palatable Chlorella and fed these compound-treated cells to two clones of Daphnia pulicaria that had shown differing responses to a diet containing a strain of Microcystis aeruginosa that produces microcystin. The Daphnia that performed better...
