This research aimed to study some chemical characteristics of rainwater in the region located at the East of Baniyas area the coastal region of Syria . Baniyas area contain complex of industrial facilities including oil refinery, electrical power generation station and oil transportation. pH values, concentration of trace metals (Pb, Cu, and Cd) and major ions (Ca2+, Mg 2⁺, Na⁺, NH₄⁺, K⁺,SO₄2-, NO3⁻, Cl⁻, F⁻) were determined during the period from October 2012 to May 2013. Samples were collected from 15 sites differ in distances from the emissions sources. Most of samples have normal pH value. The pH values decreased while the concentration of SO₄2-, NO3⁻, and trace metals Pb, Cu, Cd increased significantly by getting closer to emission source up on 2500m. The changes of the chemical characteristics of rainwater were significant.
