جمعت 370 عبوة مياه معدنية طبيعية غير مكربنة (محلية و مستوردة) ذات تواريخ تعبئة مختلفة من الأسواق السورية مباشرةً خلال العام 2006 . لوحظت الكثافات البكتيرية الأعلى في المياه المستوردة و في العبوات الأقـدم مـن كـلا المـصدرين (المحلية و المستوردة).
A total of 370 bottles of noncarbonated natural mineral water (domestic and imported) with different bottling dates, were collected directly from the markets in Syria one word one year 2006. Bacterial diversity was approached with tentative identification of the strains isolated using biochemical and enzymatic criteria (with the aid of API 20 NE identification system for nonfermenters).

Alsin Spring is the most important water sources in Syrian coastal area, due to it is the source of drinking water for the main cities and towns in the Syrian coast. This research aimed to study some contaminant indicators in Alsin spring and some t
aps of distribution system of Alsin drinking water, and compare the Indicators with samples of bottled drinking water from Alsin spring and three other water sources (Drekish, Bukkeen, and Alfigeh). The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and nickel in water samples. The results showed that all water sources contain varying concentrations of lead, while the nickel and cadmium were vary in drinking water samples; The concentrations of nickel and cadmium in some samples were low while were under the detection limits in other samples. The analysis of samples of bottled drinking water showed that the samples from Alfigeh spring were the lesser contamination with heavy metals, while the samples from Alsin spring were contain highest concentrations of lead and nickel. The samples of bottled water from Bukkeen spring contain the highest level of cadmium. The results showed that the concentrations of nitrate, nitrite and heavy metals differ depending on the water source. However, all these concentrations were lower and within the acceptable limits of Syrian standard for drinking water. The study concluded that water resources in the coastal area are distinguished with their higher pure.
This research studies inflation and its reasons in the Syrian
economy using (1990-2010) data, also it studies imported inflation and its reflects on inflation rates, considering that the imported inflation is one of the major drivers of inflation in
transitioning economies.
We find that the imported inflation has a significant effect on
inflation rate, and it leads – beside endogenous factors – to high
inflation rates. Hence, there must be coordination among economic policies to achieve the balance between money market and commodities market, in addition to the optimal use of the potential sources, thus less import.
يعد الماعز الشامي في سورية من الحيوانات الزراعية المحلية الهامة لما يملكه من مزايا ومواصفات تمكنه من الإنتاج والتناسل تحت الظروف البيئية القاسية لهذا فقد استخدم في برامج الخلط التربوي مع الماعز الجبلي كمعطي لمورثات صفة إنتاج الحليب الجيدة للحيوانات الخليطة
This study was conducted to determine some heavy minerals in different types of
canned meat sold in the domestic market. Most of those cans were imported and processed
in different countries and they have different brands. The chosen samples after
ashing were
prepared by using concentrated extra pure Nitric and Hydrochloric acids .The ratios of the
minerals )pb , Cd , Ni , Zn , Cu , Mn , Fe ( were determined by Atomic Absorption
Spectrophotometry , and the content was expressed as (p.p.m) wet weight. It was observed
that the levels of Lead, Iron, and Cadimum, in all different samples were higher than the
permitted limlts according to the Syrian Standards . The Cu level in both , tuna and sardine
was within the permitted limits, but it was higher in the chicken Lunchoen. The level of
Zinc was within the permitted limits according to the Syrian standards. The highest ratio of
Lead was observed in the sardine imported from Morocco which was 8.765 p.p.m and in
the Lunchoen processed in Syria which was 5.18 p.p.m ,and both ratios are much higher
than the permitted limits according to the Syrian Standards.
The problem of drinking water scarcity exacerbates in some villages in Tartous
governorate making water conservation a priority. The aim of this study is to identify
the patterns and practices of household water consumption of a sample of water
su
bscribers in Tartous governorate in order to determine the procedures through which
to rationalize the consumption of drinking water. For this purpose, a survey of 150
household water subscribers was conducted. The answers were then subjected to a
statistical analysis. The results indicated the presence of a high percentage of those who
follow the procedures for rationalizing the consumption of water within the sample
(95.3%), and a low percentage of those who have the techniques for reducing water
consumption (4.7%). The majority of those surveyed (87.3%) objected to increasing the
price of water as a measure to reducing water consumption. The study revealed that
there is a good aqueous awareness in the governorate on which one can rely in
rationalizing the consumption of drinking water through awareness campaigns.
