تهدف هذه الدراسة إلى معرفة تركيز الكافيين في مشروبات الطاقة المتوفرة في سورية للتأكد من أن تراكيز الكافئين في مشروبات الطاقة تخضع لتوصيات منظمة الغذاء و الدواء FDA أم لا, و أيضاً للكشف عن وجود الكحول فيها. أخذت ثلاث عينات من مشروبات الطاقة المتوفرة في سوريا و تم دراستها في هذه التجربة. تم تحديد محتوى الكافيين في هذه العينات باستخدام جهاز UV Spectrosoopy . تم الكشف عن وجود الكحول في العينات المدروسة باستخدام اختبارات مميزة للكشف عن الزمرة –OH الكحولية و تم التأكد من نوع الكحول في مشروبات الطاقة هذه. و أظهرت هذه الدراسة أن العينات الثلاث تحوي كميات متفاوتة من الكافيين إلا أن المحتوى العالي من الكافيين وجد في النوع MARINASE TURBO51.81 ميكروغرام / 100 مل و المحتوى الأقل ظهر في النوع XXXL FLASH RED1.89 ميكروغرام / 100 مل . و تم إجراء استبيان على عينة من الأشخاص و عددهم 130 شخصاً في منطقة القدموس _ التابعة لمحافظة طرطوس، و تبين أن لمشروبات الطاقة تأثيرات سلبية لمتناوليها و خاصة الشباب ، و أظهرت الدراسة غياب الكحول من مشروبي الطاقة flash redXXXL و power horse في حين تأكد وجود الكحول في العينة Marinas Turbo.
The aim of this study is to determine the concentration of caffeine in energy drinks available in Syrian market to ensure whether the caffeine concentration in them follow the FDA recommendation or not , and detection the presence of alcohols . Three types of energy drinks available in Syria are studied in this experiment. Caffeine content is analyzed and quantified by UV spectroscopy. Specific tests for alcohol hydroxyl are used to detect its presence and determine the alcohols type. This study has shown the existence of variable quantities of caffeine; however the highest percentage is existed in Marinas Turbo 51.81 micro gram/100 ml and the lowest percentage is existed in XXX L Flash Red 1.89 micro gram/100 ml. Research has shown that energy drinks have negative effects on their users , especially the youth.A survey is done on a sample of 130 people in Alqadmous – Tartous. No alcohol is found in XXX L Flash Red and Power Horse, but it was found in Marinas Turbo.

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.
Formaldehyde is classified by the World Health Organization (International Agency
for Research on Cancer) as a carcinogen in Group 1. The upper limit allowed for use in
cosmetic products as a preservative has to not exceed 0.2%. This study aims to
detect and
determine formaldehyde level in some cosmetic products available in the local market
using acetyl acetone method. Formaldehyde was detected in 77% of the studied cosmetic
products (49 samples) despite the fact that most of them were not labeled formaldehyde or
formaldehyde donor preservatives (about 70%). The amount of formaldehyde in keratin
samples were higher than the allowed limit (0.34% -11.73%) except one sample 0.18%. pH
decrease and temperature increase of keratin samples led to an increase of formaldehyde
level as a result of its release from preservatives.
In this research, the changes on these seeds during storage:
total oil, volatile oil, and the major components of volatile oils were
determined. A decrease in the total and volatile oils and all
components of volatile oils were found.
Three hundreds and thirty samples of raw milk and some of the Syrian
dairy products collected during 2002-2003 from different areas of Syria, and
were used to detect the presecne of Listeria in these products.
Results indicated that mainly L. mono
cytogenes and to a lesser degree
L.innocua and L.ivanovii were found in these products. The perecentage of
violating of the Syrian standards was 4 % in raw milk, 0.0% in pasteurized
milk, 2% in white cheese, 0.5% in shinglish and 0.0% in ice cream. And it has
been deterhmined the identity of the isolated bacterial species of Listeria from
the above-mentioned products, where L. monocytogenes was dominant, and to a
lesser estent were L. innocua and L. ivanovii.
Two hundred fecal samples were randomly collected from various
aged broiler flocks farms, which suffered from diarrhea or
respiratory problem or both in Tartous and Latakia Provinces of
Syria.
This study demonstrated the infection of the broiler
flocks with
Cryptosporidium in Tartous Province of Syria with a rate of 5.6%
only.
The results of tests based on morphology and size of
Cryptosporidium oocysts showed that the parasite is probably
C. baileyi which ranged in size about (6 μm X 4.5 μm).
