| Abstract | ||
| This study was included identification of phytoplanktons in sedimentation basins in purification drinking water stations of petrochemical and AL-Ribatt in Basrah governorate for six month from September 2013 to February 2014 , Included measurements of some physical , chemical and biological factors affected on phytoplankton growth with measurement the concentration of some important nutrients ( Nitrate , Nitrite , Phosphate and Silicate ) . This study also measurement the concentration of hepatotoxins ( Microcystins ) in drinking water as the first time in Iraq .Study was showed dominance of phytoplanktons of class : Cyanophyceae reach to 37.5 and 40 % in two AL-Ribatt and petrochemical company station respectively followed by other calsses Bacillariophyceae , Chlorophyceae and Euglenophyceae on arrangement. Nitrate concentrations in two station reach between 1.7 -26 μg /l , Nitrite 0.043 – 1.5 μg /l , Phosphate 0.01 – 0.42 μg /l and Silicate 10.1-57.6 μg /l . significant differences are found between months in two stations . The quantitative study was appeared that the mean number of non-diatoms algae range between 288-560 × 103 cell / L in AL-Ribatt station and range between 352-496 × 103 cell / L in petrochemical company station , while diatoms range between 33-118 × 103 cell / L in AL-Ribatt station and between 33.84-118 × 103 cell / L in petrochemical company station . The concentration of hepatotoxin ( Microcystins) in two station range between ( 0-2.86 ) μg /l the highly value were recorded in September in AL-Ribatt station with non-significant differences between two station while significantly between months month in MCs concentration at probability levels p≤0.05 . | ||
