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.
In this study the concentration of (Cu, Cr, Cd, Fe, Mn, Ni, Zn , Pb ,V &Co) in
some sedimentary columns and pore-water extracted from the estuary of Al-Kabeer
alshemali river was determined during four seasons .the concentrations of these metals
w
ere determined using atomic absorption spectroscopy (AAS). The columns were cut into
slices with 2cm of thickness ,the pore water at every slice was extracted using
centrifugation (7000 r/min).the results showed that the concentration increased from
surface(deep=0cm, rich of O2) up to the 4cm of deep ,then the concentration decreased in
deeper slices (down of 4cm,deficiency of O2) and the concentration of Fe and Mn from
high ranking ppm. The rest of the items were relatively lower ranking ppb, but Co, Cd and
V were low. meat increased the concentration of all these elements in the spring and
summer, compared with the values in the winter and autumn, due to increasing human
activities on the one hand and the high temperature on the other hand, leading to increased
activities of bacterial that leads to the decomposition of organic material that may increase
the ratios of these elements in the pore water.
