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 g
eneration 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.
The aim of this study isto determinat the concentration of (Pb, Cu, Cd, Co, Cr , NiZn,
Fe) in storm water and their content of sediments during four seasons, the samples were
collected in four areas along Tartous beach. After make necessary treatme
nt concentrations
of elements determination by flame atomic absorption spectrometry.The results showed a
high levels of elements iron and zinc, in stormwater (138.6 μg/l - 99.7 μg/l) and sediments
(17.863 μg/l – 138.735 ppm), in all samples and there were concentrations another
elements difference between stations and rainfalls related to the human activities.
As a result of the expansion of system of sewerage and rain water networks to serve all areas in Tartous city especially its industrial area, it was not associated with proper wastewater treatment including the separation of rainwater from sewage and
building wastewater treatment plants. With the increased number of factories in the industrial area , the population growth in the city of Tartous, the demand for industrial needs, the poor investment for networks, the clogged lines and insulting them by mixing municipal, industrial and rainwater sewage and large precipitation for Tartous city Basin, and the difficulty of discharging wastewater according with gravity to the treatment plant And the lack of possibility to drain rain water with large flows, the study of the current situation of municipal, industrial and rainwater sewage to develop solutions for it.
