This study aims to identifyzeolite phases within the sedimentary-volcanic deposits in Banyas region because of their scientific and economical interest. A group of samples chosen from different sites in the region were studied using X.R.D instrument
with X-powdersoftware. The studies samples were divided into three groups: Igneous, sedimentary and zeolite deposit groups. zeolite deposit, in turn, were put in two subgroups: a new zeolite and already known zeolite subgroups in other regions in S.A.R. The results of this study are quite new in Banyas region.
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.
Zeolite bearing deposits were characterized in Banyas region using sample A
(which is a powdered mixture taken from five tuff and tuffite levels) compared with
sample B (which is taken from Basatin Al-Assad site within the studied region).
XRD met
hod showed several zeolite phases in addition to non-zeolite minerals
and volcanic glass. FTIR method revealed a general feature of zeolite groups. DTA
method showed a range within zeolite structure stability. Specific surface area was
measured using BET method giving the value 87m2/g. The range of pore volume
distribution was also calculated with ~40Ǻ, and intermediate pore diameter of ~23Ǻ.
XRD study of the standard sample (B) showed slightly different zeolite phases
from A. FTIR measurement showed same results as in A. DTA plots revealed a high
stability of sample B, SBET of 61m2/g, VP around 40Ǻ and r- at ~25Ǻ.
Uncontrolled disposal of produced water from oil and gas industry in the
environment involves the environmental hazard like contamination soil by NORM and
increase the radiation exposure to terrestrial gamma radiation by workers and public. the
st
udy aims to measure radiation levels in the drainage zone and vicinity in the field of
crude oil storage tanks in the site of Syrian company for oil transport in Banyas. Terrestrial
gamma radiation dose was measured, the values ranged between 0.02 – 0.24 μSv.h-1. The
radioactivity concentrations of NORM were determined for Ra226, Th232, K40 by gamma
spectroscopy using HPGe detector in surface soil samples taken from three sites, two of
them recorded the highest rate of radiation dose, while the third recorded the rate of
radiation background. The Ra226, K40, Th232highestconcentrations in the soil samples were
found to be 210, 213 and 55.9 Bq.kg-1, respectively. Radiation indexes were estimated.
The present results were compared with results published in different countries.
