| Abstract | ||
| Lake Burullus face tremendous ecological stresses due to rising of pollution originated from the discharges of the drains without treatment; eight stations were monitored in order to assess the eutrophication and the pollution levels at these stations using some species of phytoplankton as bio-indicator to the pollution. An average density of 1.406000 units l-1 phytoplankton belonging to four divisions namely; Euglenophyceae, Bacillariophceae, Chlorophyceae and Cyanophyceae were identified. The most abundant genera at these stations were Euglena spp. and Phacus spp. (euglenords), Scenedesmus spp. (chlorophytes), Cyelotella spp. and Nitzschia sp. (Bacillariophyceae), while the genera of Merismopedia spp. and Microcystis spp. were the most dominant among cyanophytes (blue-green algae). These genera were the most dominant at the stations near to the drains which affected by the discharges originated from the drains (organic pollution) as well as the high levels of nutrient salts especially ammonia nitrogen (eutophication). The members of euglenoids were the most indicators to the pollution at station 2, 3 and 7 near to the drains. | ||
