| toxic cyanobacteria and their toxins in standing waters of kenya: implications for water resource use. | phytoplankton biodiversity studies in kenya's standing waters were carried out between 2001 and 2003. toxin producing cyanobacteria were recorded in twelve water bodies. microcystis and anabaena were the most common species in freshwaters while anabaena and anabaenopsis were common in alkaline saline lakes. seven lakes with cyanobacteria blooms and a hot spring had detectable levels of microcystins and anatoxin-a. cell bound microcystins (lr equivalents) concentration ranged from 1.6-19800 micro ... | 2006 | 16813016 |
