Hydrochemical study of Rain Water In Baghdad city-Iraq

AbstractThe chemical substance dissolved in rain water are generally considered to have two atmospheric
sources, dry fallout and/or soluble salts. The present study deals with the rain water year 1995-1996 at
Baghdad city were expressed in term of monthly averages of the collected samples . The concentrations
values of cations (Ca, Mg, K and Na) and anions (Cl, SO4 and HCO3),were expressed as average
annual. All ions concentration, are found to be within the excepted range of fresh water. These results
were compared with rain water year 1985-1986. Appreciable reduction in concentrations of both cations
and anions have been recorded, and the percentages of reduction are ranging between 28% to 84%.
Moreover, by adopting fractionation factor, the results revealed that the sea water have less contribution
of all ions concentration than other sources (local activities). The results of the chemical analysis were
dealt with statistically by using cluster and factor analysis .
