The chemical parameters and total metal concentration of sediments are presented in Tables 3 and 4. The average pH in sediment was 6.5 which is near about neutral. The composition of the organic carbon in sediment samples was varied among the sites due to its origin in the aquatic environment. The organic carbon in sediments ranged from 0.74 to 2.5% during winter and 0.98 to 1.8% during summer (Table 3). A wide range of values for metal concentrations was observed among the sampling sites. Factors such as salinity, geomorphological setup and land runoff
