أجريت هذه الدراسة في المنطقة الساحلية السورية، و تم جمع عينات عسل النحل من ثمانية مواقع مختلفة تابعة لمحافظتي اللاذقية و طرطوس خلال فصل الخريف لعام 2012، و تقدير محتواها من العناصر الثقيلة (الزنك، و النحاس، و الرصاص و الكادميوم) بوساطة جهاز الامتصاص الذري في المعهد العالي لبحوث البيئة بجامعة تشرين. أظهرت نتائج التحليل أن تركيز الزنك في عينات عسل النحل تراوح بين 2.86 و 12.64 مغ/ك، (متوسط 7.98±3.67)، و النحاس بين 0.125 و 0.652 مغ/كغ (متوسط 0.328± 0.176)، و الرصاص بين 0.084 و 0.378 مغ/كغ (متوسط 0.205± 0.112)، و الكادميوم بين 0.0002-0.0132 مغ/كغ (متوسط 0.0053±0.0052). و تبين من النتائج أن أكبر تركيز للعناصر الثقيلة كان في عينة العسل المأخوذة من المنحل الواقع في المدخل الشرقي لمدينة اللاذقية (قرب معمل الجود)، بينما كانت أقل التراكيز للزنك و الرصاص في منطقة بانياس (وادي السقي)، و للنحاس في صافيتا، و للكادميوم في منطقة جبلة (قلعة بني قحطان). و بمقارنة تركيز العناصر في عينات العسل المدروسة، وجد أن تركيز الزنك كان الأعلى، يليه النحاس، ثم الرصاص، و أخيراً الكادميوم. و تشير نتائج التحليل الإحصائي إلى وجود فروق معنوية بين المواقع المدروسة خلال فصل الخريف لعام 2012.
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, lead & 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.

Because rainfall in the coastal area is high and water projects are nearly missing, we think it is important to make use of available water resources. In order to predict future rainfalls and suggest proper management of resources, we created a mathe
matical model linking rainfall amounts between demand (population, agricultural and industrial) on water resources during the period (2000-2012). Results show the following:
1. Rainfalls decreased during the period ( 2002-2012) at an annual rate of (1.84%).
2. Demand on water resources increased during the period (2002-2012) at an annual rate of (3.41%) of the population demand, and (3.47 %) of the agricultural demand, and 6.25% for industrial demand.
3. There is a surplus of available water resources and the size of demand for them, with the surplus decreasing during the period (2002-2012) at an annual rate (2.97 %).
4. The estimation of the surplus between the amount of available water resources and the size of the demand for them will decrease in 2023 from what it was like in the year 2013 at an annual rate (-3.23%).
The research aims to estimate allocated to quench agricultural areas in the coastal region, the amount of water during the period 2002-2012 in case of the use of modern irrigation (drip and sprinkler irrigation) instead of the traditional surface irr
igation according to water legalized each method and the rate of efficiency, as well as to estimate the losses in irrigation networks allocated to agriculture and the development of appropriate pricing mechanisms of government. Find the historical and descriptive approaches adopted, and it was the most important results:
1- The results showed that if the use of drip irrigation surface irrigation in the quench-based surface irrigation acreage allowance contributed to supply up to 40% of the water used in surface irrigation amounts, and an average (174 973 785) cubic meters during the period 2002- 2012.
2- The results showed that if the use of sprinkler irrigation surface irrigation instead of the quench-based surface irrigation acreage for contributed to the supplied amount to 28% of the water used in surface irrigation amounts, and an average (122 481 649) cubic meters during the period studied.
3- economic pricing of agricultural water demand for current pricing varies, it was found that there is a deficit in the recovery of operating and maintenance costs of the territory of farmer beneficiaries of the water public irrigation networks and adult (21,500) per hectare, compared with what is being collected (3500) for. Q per hectare.
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.
Drought is one of the most important challenges facing sustainable development in eastern Mediterranean regions, where water resources are already limited and ecosystems are fragile. Sums of weighted standardized monthly precipitation anomalies were
used to assess annual drought intensity, frequency and spatial extent in five climatic stations located in Syrian coastal region during the period 1966-2008.Changes in drought intensity were detected using trends with Mann – Kendall test. Results show that drought occurs with high frequency over all parts of the coastal region(up to 35% in some parts),but with different intensities.Extreme drought can hit all regions in some years as happened in 1972-1973. Moreover drought may strike the same region for three consecutive years (1988-1991). Also the results show an increasing tendency in drought intensityrelated to the decreasein drought index values (between 0.29-0.96). This can have serious ecological and economic consequences and will pose an increasing challenge to agriculture and the management of water resources in this region.
Changes in precipitation patterns are considered one of most important hazards facing terrestrial ecosystems and water resources worldwide. Monthly rainfall data for six meteorological stations located in the Syrian coastal region were used to study
changes in precipitation characteristics during the period 1960-2010. Trends with mann- Kendall Test, Gamma Distribution and Precipitation Concentration Index (PCI) were applied to detect changes in seasonal and annual precipitation amount in addition to seasonality. Results showed significant negative trends in annual precipitation in all stations up to 30% in some cases, which could be related to the decrease in spring and winter rainfall amounts that ranged between 38.5% to 50.2% in spring and 14% to 38% in winter. Despite significant decrease in annual precipitation, there were no significant trends in seasonality. These changes in precipitation patterns would pose big challenges to water resources management , agricultural production and forests management.
