دراسة بعض مصادر التلوث البيئي في مياه نهر الفرات بين مدينتي هيت و الرمادي

STUDY OF SOME POLLUTION SOURCES FOR EUPHRATES RIVER WATER BETWEEN HEET an‎d RAMADI CITIES

Absrtract: The research involves the study of expected environmental pollution in Euphrates river water between Heet and Ramadi cities as a result of different human activities . Samples were taken from different places of river , i.c., Heet , Mohammady , Zoweyah , Tal aswad , Zankorah , Abodheab , and Ramadi . The physical and chemical properties of water samples were studied like pH , Total hardness , temperature , suspended sediments , dissolved solid , turbidity , conductivity ,The concentration of calcium , magnesium , sodium , potassium , phosphate ,sulphate , sulphide , chloride , fluoride ions were determined . Some trace elements like Cu , Ni , Zn , Pb and Cr were also determined . The analysis shows varitey of result compared with the national and Iraqi standards . The physical properties , for instance , the temperature , suspended sediments are within the allowable limits , whereas the conductivity , dissolved solid , and turbidity were higher than the allowable limits in same places . The chemical properties were within the allowable limits except increase in the concentration of SO4-2 , HCO3- and PO4-3 ions which show on increase in other places which reflects the bad environmental situaties in the river and affect its validity for domestic use . The concentration of trace elements , i.c. , Cu , Ni , Zn , Pb and Cr were less than the allowable limits which means that the water is not polluted py these elements
