Abstract
The main objective of the present study was to monitor water quality of El Salam canal and and Tineh plain and realize to which extent the Hadous drinage affected the pollution status of El Salam canal and its extension, using the physicochemical and phycological criteria to assess the water quality. Ten sites, six sites of them west Suez canal and four sites east Suez canal, the bimonthlty sampling collection was started from Novmber 2002 to November 2003. The investigation of the physicochemical properties of water displayed great local variations due to the different in nature and quantity of the discharged wastes. A total of 201 taxa belonging to 76 different algal genera; 32 taxa Cyanophyta, 56 Chlorophyta, 26 Euglenophyta,1 Xanthophyta and chrysophyta and 79 Bacillariophyta were identified. Total phytoplankton standing crop (cell number) was mainly represented by Bacillariophyta (72 %), Chlorophyta (22.5 %), which represented by the bloom of Chlorella vulgaris var. vulgaris. at sites IX and / or X . Generally, diversity index indicates that this area is moderate pollution and Saprobic index indicated slightly contaminated mesosaprobic). The saprobic quotient revealed that gb smesosaprobic at the study area with slight pollution. The statistical analyses reflect the effect of the water quality of El Salam canal and its extension by Hadous drain. Also, the results of (AGPT) test indicate that El Salam canal water is actually injured and deteriorated heavily by various pollutants especially heavy metals from Hadous drain. and fish feeding.
