ABSTRACT
Water samples, sediments
from three stations in Euphrates River, Iraq were analyzed quantitatively for
some physical and chemical characters and six heavy metals (Co, Cu, Fe, Mn, Ni
and Pb) using flam atomic absorption spectrophotpmeter in period Sept. 2009-Oct.
2010. The physical and chemical characters included temperature, pH, water
flow, salinity, dissolved oxygen, BOD5, alkalinity total hardness, calcium and
nutrients (nitrite, nitrate reactive phosphate and silicate). The results
showed variation in water flow 0.05-0.40 m/sec., according to the values of
salinity 0.40%-0.60% values of the BOD5 were ranged between 0.2-4.3 mg/L. The
mean concentration of the heavy metals (Pb, Ni, Mn, Co, Cu and Fe) of the
dissolved phase in water were 0.13 µg/L, 0.021 µg/L, 0.31 µg/L, 4.29 µg/L, 7.78
µg/L, 6.46 µg/L and 79.04 µg/L, respectively, while their concentration in the
particulate phase were 0.59 µg/g, 0.06 µg/g, 0.42 µg/g, 50.06 µg/g, 6.61 µg/g,
7.17 µg/g and 149.42 µg/g dry weight, respectively. Also the mean
concentrations of heavy metals in sediment (exchangeable phase) were 0.51 µg/g,0.18
µg/g, 0.08 µg/g, 61.39 µg/g, 5.40 µg/g, 14.06 µg/g and 130.05 µg/g dry weight
respectively, and 0.40 µg/g, 0.17 µg/g, 0.10 µg/g, 63.01 µg/g, 4.64 µg/g, 18.44
µg/g and 126.26 µg/g D.W. respectively in residual phase of sediment.
