تم في هذه الدراسة تحديد الكمية الكلية و تركيز الشكل المتبادل لكل من الزنك و الرصاص في الترب الزراعية الواقعة في منطقة بانياس, حيث قمنا بأخذ عينات التربة من خمسة مواقع من الجهة الشمالية الشرقية للمحطة الحرارية.
This study determined total quantity and exchangeable form concentration of zinc and lead in the agricultural soils in the Banias region. Soil samples collected from five sites from the north-east of the thermal station.

The aim of this study was to estimate the total amount of phenolic compounds of olive
trees leaves (Olea europaea L.) as Biomarker for the assessment of lead air pollution at
Banias area. Olive trees were selected as the predominant species in the
study area. The
samples were collected from 6 locations at different distances from the vicinity of the
Banias refinery (0.1, 0.5, 2, 4, 6, 10) Km. The dominated wind in the region is western -
southwesterly during the winter (March) and summer (September), The control was taken
from an area about 20 km from the refinery to the north-east (al-Qardahah rural).
The concentration of total phenolic compounds (TPC) during the summer was (45.6-70.85)
mg GAE/g dw and in the control (40.4) mg GAE/g dw, and during the winter the content
of TPC was (35.6-52.9) mg GAE/g dw and in the control (25.8) mg GAE/g dw. The
concentration of Lead (Pb) in unwashed leaves during the summer was (0.879 – 2.170)
ppm and in the control (0.005) ppm, whilst during the winter was (0.479-1.023) ppm and
in the control (0.00083) ppm. The results showed significant differences in the
concentration of total phenolic compounds and lead between sites (Anova test). High
concentration of total phenols and lead in the summer compared to values in winter at all
sites (t-test). The results also showed a negative correlation between the concentration of
total phenolic compounds and lead with the distance from the refinery of Banias. Finally,
The results showed that the TPC can be used as biomarker of lead air pollution in Banias
area.
This study aims to investigate the abilities of two tree species (Pinus brutia and
Cupressus sempervirens) planted in Banias Refinery Company to absorb and accumulate
lead and zinc basically emitted by the Refinery. Samples of the planted species (
leaves,
bark, and wood) and soil from around the plants were collected and analyzed by atomic
absorption spectrophotometer. The results did not show significant pollution with these
two elements. Moreover, there were not any significant differences between the two
species in terms of the accumulation of Pb and Zn. While the Pb concentrations ranged
between (24.96-30.84 ppm) for P. brutia and (24.05-30.23 ppm) for C. sempervirens, the
Zn concentrations ranged between (34.99-82.99 ppm) for P. brutia, (18.11-59.86 ppm) for
C. sempervirens. It was also revealed that P. brutia bark accumulated Pb more than the
other parts, whereas C. sempervirens leaves accumulated Zn more than the other parts.
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.
Debate on the sustainability of human settlements has recently been focused
primarily on the urban portion of the land use pattern. However, urban
areas rely on suburban, rural, and other less densely settled lands for their
existence. In order to
quantify the impacts of various land patterns on their
supporting resources, these exurban lands must be included in any
sustainability assessment. This need for a regional view has resulted in a
measurement method that enables comparisons of relative sustainability
between various regional land use patterns.
Food safety and monitor of the contents of agricultural products are matters of great
importance for consumers, as a result of food awareness, public health and disease
prevention.
The aim of this study is to know the concentrations of some heavy
metals (lead -
cadmium - nickel - chromium), in some fodder plants (Trifolium ssp., Cynodon dactylon.,
Avena sativa L.), and the extent of its secreted in the milk of cows in the area of Banias on
the Syrian coast.
