الدراسة الحالية اختبرت ثلاث انواع من نفايات الخضار والفواكه( قشور الموز, قشور النارنج, قشور الرمان) من اجل اصلاح بعض الانظمة المختبرية من خلال قابليتهما على معالجة التربة الملوثة ببعض المعادن الثقيلة والتي تنتج من بعض المعدات المختبرية. وتمثل المعاملة C معاملة السيطرة = مياه ناتجة من التربة الملوثة فقط . كلا النباتين تم تعريضهما لللمعادن (Pb, Cd, Cu, Fe, Zn) ولفترة زمنية هي ثلاثة اسابيع لتسجيل مدى التحمل اسبوعيا. وبواقع ثلاث مكررات لكل قراءة. استعمل جهاز مطياف الامتصاص الذري لتحديد تراكيز المعادن. النتائج اظهرت بانه على الغالب وجدت فروقات معنوية في تراكيز كل عنصر تجاه المعاملات خلال فترة التجربة. الهدف من هذا العمل هو ايجاد طرق سهلة وصديقة للبيئة تقلل التلوث في النظام البيئي.
The present study was testing the three type of waste (orang crusts, pomegranate crusts, banana crusts) for repairing some lab ecosystems through their ability of treating contaminated soil with some pollutants metals that produced from some laboratory equipments. C = contaminated soil only that consider to be a control test. Both plants were exposed to heavy elements (Pb, Cd, Cr) for a period of three weeks and record the tolerance range weekly, all data recorded was triplicate. Atomic absorption spectrometer used to estimated metals concentrations. The results show that mostly there are significant differences at each mineral concentration towards treatments during tested period. Aim of this work is to find a simple and friendly ways to limit the contamination in aqua ecosystem.

The samples of bee pollen were collected from inside and outside
the honey beehives of apiaries situated in five different locations of
Latakia; Al-Qardahah, Al-Haffeh, Jableh, Latakia city and Eastern
Entryway to Latakia during the autumn in 2014
. The
concentrations of three heavy metals, zinc (Zn), lead (Pb), cadmium
(Cd) were determined in pollen by using atomic absorption.
Heavy metals determination was carried out in ٢٤ of vegetable crops, belong
to three groups, i.e.: Leaf, Fruit and Tuber vegetable crops. Lead, Chromium,
Cadmium and Mercury, were determined using Atomic Absorption
Spectroscopy provided with Graph
ite furnace. Vegetable samples were
collected from six sites along the irrigation water source for Barada and
Ghouta for two seasons, ٩٥-٩٦ and ٩٦-٩٧, to evaluate the effect of water source
(surface polluted water and ground water) on the heavy metals content of
vegetables.
In developing countries, including Syria solid waste sector contributes to the
emission of greenhouse gases, mainly methane, due to the lack of methods of integrated
management of solid waste in these countries.
The objective of this research is t
o study the feasibility and effectiveness of
mechanical biological treatment of municipal solid waste in a way to reduce methane gas
emissions compared to the way the indiscriminate dumping of municipal solid waste. In
order to reach this goal is the use of the formula contained in the guidelines of the
International Panel on Climate Change (IPCC) in account the emissions of methane from
municipal solid waste sector in the Syrian Tartous in the case of landfilling of municipal
solid waste generated by the province during the years from 2010 until 2015 in random
landfills. In order to compare the account is an assumption that the same amount of
municipal solid waste generated by the province during the years from 2010 to 2015 have
been treated in accordance with the mechanical biological treatment method. It was also
calculate the amount of methane emitted from municipal solid waste entering the
integrated waste treatment center in the Province of Tartous within one year from the
beginning of June 2014 until the end of May 2015, using mechanical biological treatment
method.
This study concluded that the mechanical biological treatment for municipal solid
waste significantly reduces the amount of methane emissions from solid waste sector
compared to the landfill, where the percentage of reduction in the emission of methane
93%.
Dark circles around the eyes cause cosmetic and psychological problems. They are the most common cause of major cosmetic problems after wrinkles. Thus there is a need to look for new therapeutic options to improve the unacceptable cosmetic cases.
In our research, we evaluated the effectiveness of each fruit acid and vitamin k in the treatment of dark circles around the eyes in 120 patients. The patients were randomly divided into three groups of 40 patients each. In the first group, fruit acid of 40% density was used as the only treatment. In the second group, topical vitamin k of 2% density was used as the only treatment. In the third group, both of fruit acids and the vitamin k were used for treatment. The goal of this study was to determine the best therapeutic protocol to treat dark circles around the eyes
This study was conducted in the Syrian coastal region, and the honey samples have
been collected from eight different sites belonging to the provinces of Latakia and Tartous
during the autumn of 2012. Their content of heavy metals (zinc, copper, le
ad & cadmium)
was estimated by Atomic Absorption at the Higher Institute for Environmental Research at
Tishreen University. The results showed that zinc concentration in the bee honey samples
ranged from 2.86 to 12.64 mg / kg (mean 7.98±3.67), and copper ranged from 0.125 to
0.652 mg / kg (mean 0.328±0.176 ), lead ranged from 0.084 to 0.378 mg / kg (mean
0.205±0.112), cadmium ranged from 0.0002 to 0.0132 mg / kg (mean 0.0053±0.0052). The
results indicated that the largest amounts of heavy metals were found in honey sample
taken from the apiary which is located at the eastern entrance of Latakia city (near Joud
factory), while the lower concentrations of zinc and lead were in Banias area (Wadi Al
Saqi), and the least concentration of copper was in Safita area, and of cadmium was in the
Gablah area (Bani Qahtan Castle).Comparing elements concentration in the studied honey
samples, Zinc concentration was found to be the highest, followed by copper, lead and then
finally cadmium.The results of statistical analysis indicated the existence of significant
differences between the studied sites during the autumn of 2012.
