| Abstract | ||
| Chemical compounds concentrations in rain water collections are derived from two main sources: aerosols blown by wind and carried through rain storms, and organic and inorganic matters dissolved along water courses and in water catchments. Chemical analysis of samples collected from rain water collections scattered in three sampling sites in Qunaitra governorate namely Koudaneh, Al Koum and Al Baath City during the time interval from October 2010 to April 2011. The cations NH4+، Na+، Ca+2، Mg+2 and the anions Cl-، 2SO4-، NO3-، NO2-، PO4-3، hydrogen ion concentrations and electrical conductivities were measured. The study revealed that Na+ concentrations (6.12-13.52 mg/l),Ca+2concentrations (15.9-36.86 mg/l), Mg+2concentrations (6.8-13.49 mg/l), Cl-concentrations (16.10-29.32 mg/l), pH (7.27-8.95), EC (308-420 m.semin/cm), measured in all study sites, fall within the allowed limits of drinkable water, while NH4+ concentrations (0.6-2.3 mg/l), SO4-2 (249-256 mg/l) concentrations, NO3- concentrations (60-70 mg/l), NO2- concentrations (0.91-2.6 mg/l), PO4-3 concentrations (1.31-2.86 mg/l), surpass the limits of drinkable water. The relations between all ions were calculated for all samples to derive the potential sources of the pollutants. | ||
