تناول البحث دراسة تغير بعض الخصائص الكيميائية لمياه الأمطار في المنطقة الجغرافية الواقعة شرق مدينة بانياس؛ كونها منطقة ساحلية تحتوي عدداً من المنشآت الصناعية الحيوية، كمصفاة تكرير النفط، و محطة توليد الطاقة، و شركة نقل النفط خلال الفترة الواقعة بين تشرين أول 2012 إلى أيار 2013. و قد تضمنت الدراسة تحديد كل من قيم pH، و تركيز الشوارد الرئيسة (Ca2+, Mg2⁺, Na⁺, NH₄⁺, K⁺, SO₄2-, NO3⁻, Cl⁻, F⁻) , و تركيز نزر بعض العناصر الثقيلة (Cu, Cd, Pb) في عينات مياه الأمطار. و قد أخذت العينات من خمسة عشر موقعاً تم تحديدها بحيث تمثل منطقة الدراسة. و أعطيت أرقام تسلسلية حسب تسلسل بعدها عن المنشآت. و أظهرت النتائج أن أغلب عينات مياه المطر كان لها pH معتدل تقريباً. و لوحظ ارتفاع تدريجي لدرجة الحموضة (انخفاض قيم pH), و كذلك لقيم تركيز SO₄2- و NO3⁻, و لتركيز نزر العناصر الثقيلة Cu, Cd, Pb مع القرب من مصادر الانبعاث لمسافة تزيد عن 2500 م. و قد خلصت الدراسة إلى أن الخصائص الكيميائية لمياه المطر تتأثر سلباً و بشكل معنوي بالقرب من المنشآت الصناعية.
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.

The research has been conducted in different sites in lattakia, Alhamra and alsabahia
villages of Rabea and Aen alzarqa of Mashqeta. 14 cases of precipitation was marked
which caused runoff and water erosion of soil during the research (seasonal ra
infall in
2011/2012). Samples of rain water of every precipitation case were collected. by using rain
gauges that were installed in the research sites. After that, samples were moved to the
laboratory. The pH was determined after that the samples were analyzed by using an ion
chromatography device(IC).
This research studies some soil properties formed on calcareous rocks under a natural plant cover of wide leaves (mainly: Quercus calliprinos and Quercus infectoria) in Banias region (63 – 234) meters height above sea level.
Firstly, 3 soi
l profiles in the studied area were done, then morphological characteristic, type of plant cover and Geographic Position System (GPS) were accomplished.
Samples were taken from profile horizons, then, physical and chemical properties were determined (structure, bulk and real densities, total calcium carbonate percent, organic matter content, action exchange capacity, exchangeable calcium and magnesium, and pH).
The profile depth ranged between low and medium (60 – 137) cm, the pH ranged between neutral and alkaline (7.1- 8.2), there was an increase in calcium carbonate content in the whole profile (17- 88%), and also increase of organic matter contents in the horizon (8- 12%). Due to high clay (18-74) % and organic matter content (8-12) %, the soils showed high cation exchange capacity (CEC) (21- 92 meq/100g). Exchangeable calcium was dominant on the surface of adsorption complex (17- 74 meq/100g), then magnesium in second stage (0.2- 6 meq/100g).
From a classification point, the soils were classified under the following orders:
Entisols, Mollisols, Inceptisols, which have profile types: A – AC – C, A – AR – R, and A – (B) – C.
Soil depth and its content of rocky pieces were varied according to relief degree, plant cover intensity, and parent rocks hardness. Most of soil properties are a parent material descendible, and the soils were slightly developed and recently formed.
The research was carried out in the center of the Research and
Improvement of Sheep and Camels in salamiah. The study was
conducted on 9 female camels, within semi-open barns, semiintensive
care system, and the camels were fed on mixtures of
barl
ey, vetch and some concentrated fodder, Fodder mixtures were
determined to suit the nutritional needs of the physiological and
age-related condition of the study. The herd was also applied to the
preventive vaccination system according to the preventive immunity
program.
This research was conducted in Agriculture College (Food Science Dep.,
Damascus U university). The purpose of this research was to evaluate Cherkes
Cheese by determination some Chemical and microbial properties for 40
samples collected randomly fr
om different places Damascus and country sides.
The results showed very deferent changes in Chemical properties. The acidity
ranged between (0.25 - 0.54%), moisture content (38 - 56%), and total dry
matter (44 - 62.7%). Results also showed that all samples were rejected by
(Syrian Normal Standard)for fat content in dry matter (20 -33%). Fifty percent
of samples were rejected for their content of sodium chloride which was
(1.2 - 4.3%). Results also showed that samples were free of Salmonella and
there was no rejection for existence of Staph. aureus but 37.5 % and 10% of
samples were rejected by (Syrian Normal Standard)as per content of coliform
and E.coli, respectively.
This research was performed to study the effect of sewage water on
the surface water of the Addelbeh Valley stream, and groundwater
on both sides of the stream in Tartous Cement Factory area.
Water samples were taken from the factory water outlet
and
Addelbeh Valley water to study the content of pollutants. We also
took groundwater samples from selected wells on both sides of the
waterway in the studied area. We repeated that process every two
months for a full hydrological cycle from July 2013 to May 2014.
We found a great increase in content of the industrial drainage
water include oils and heavy metals especially iron, copper and
zinc. For example: iron concentration in sewage water exceeded
150 mg/l in all samples. Besides sewage water and stream water
contained high concentrations of ammonia and nitrite versus low
concentration of nitrate, unlike water wells samples. The study
revealed increased EC and salts concentration markedly in wells
water due to its adjacency to the sea.
