تناولت هذه الدراسة تحديد تراكيز كبريتيد الهيدروجين في رسوبيات ومياه نقاط الصرف الصحي على شاطئ مدينة اللاذقية - منطقة الكورنيش الجنوبي التي تشهد تدفقاً واضحاً من مياه الصرف الصحي وأثر البكتيريا على ابنعاث كبريتيد الهيدروجين (H2S ) ذو السمية العالية إلى الوسط المائي ومنه إلى الهواء الجوي والتغيرات الفصلية لتلك الانبعاثات ودور العوامل الهيدرولوجية مثل الملوحة والحموضة ودرجة الحرارة في هذه العملية.
This study dealt with the determination of hydrogen sulfide concentrations in the sediments and water of sewage points on the beach of Lattakia city - the southern Corniche region, which witnesses a clear flow of sewage water and the effect of bacteria on the emission of hydrogen sulfide (H2S) of high toxicity to the water medium and from it to the air and seasonal changes. These emissions and the role of hydrological factors such as salinity, acidity and temperature in this process.

This research deels for the first time the studying fecundity of species blue crab
Portunus pelagicus in our regional waters which as an introduction to breeding and culture.
This research carried out in the period from September 2011 until January
2013.
At the following three region of Lattakia coast : Fishing bort and picnic area, Ibn
Hanni area and Southern Corniche area.Biomonthly samples were collected from Littoral
and Sublittoral area of 8-18m deeps.
Studies results revealed as the following:
The number of mature females 240 female, Ranged: carapace length 4.6-7.9cm
Carapace width between 5.2-13.8cm and body weight between 49.2-171.45 g .
Spawning takes plase during the period from May until December and the rate of the
highest in the month of October.
Absolute fecundity in females of this species was ranged between 21435-143510
eggs, and relative fecundity was ranged between 1924-766651 eggs/g, and the eggs
diameters ranged between 0.25-0.45 mm.
This research has included quarterly and periodically physical and chemical analysis
of treatment wastewater in the rural areas of Latakia city during year 2011 by testing
three treatment plants similar in the mechanism of action and distributed in
three villages
(Happit, Al-Harah, Marg Moairban).
This study has included the measurement of temperature T, pH, and determination of
sodium, potassium, calcium concentrations, and sodium adsorbed rate (SAR).
This study was based on the potentiometrictechnic using Ion Selective Electrodes
(ISEs).
SAR measurements have shown that there are clear differences between autumn and
other seasons, and between treatment plants. The highest values was in the Happit
treatment plant in all seasons and the highest value was (88.25 mg/L) in the autumn which
is much larger than the allowable limit.
The highest concentrations of sodium ion were in the autumn in all treatment plants
(1002.67-7130.33) mg/L, which is off limits. As for the potassium ion concentration was
highest (72.46 mg/L) in Happit treatment plant in the autumn. While calcium ion
concentrations in Al-Harah treatment plant was exceeded (670.33-800.00) mg/L the
allowable limit in all seasons except the summer.
The statistical study has demonstrated and showed strongand sometimes weak
correlation coefficient R2 so that gives clear indications about the sources of pollution.
This research has included quarterly and periodically physical and chemical analysis of treatment wastewater in the Latakia countryside during year 2011 by testing three treatment plants similar in the mechanism of action and distributed in three v
illages (Happit, Al-Harah, Marg Moairban).
This study has included the measurement of temperature, pH, dissolved oxygen, turbidity, and determination of nitrate, phosphate, sulfate, and chloride.
In this research, potentiometric using Selective Electrodes ISEs, the Visible Spectrum, and the Turbidimetry methods were used.
The results showed significant differences in concentrations of the studied ions between one station to another. The highest nitrate concentrations (228.33mg/l) were recorded in Happit treatment plant especially in summer, and the highest phosphate concentrations (41.81mg/l) were in Happit treatment plant in summer. Whilst the highest sulfate concentrations which ranged between (508.67– 1157.33)mg/l were in Al-Harah treatment plant at all seasons. The highest chloride concentrations (310.33mg/l) recorded in Happit treatment plant in summer.
The statistical study has demonstrated and showed high and sometimes low correlation coefficient R2 so that gives clear indications about the sources of pollution.
This study aims to define bird species that use artificial lakes in Syrian coast, and
evaluate their population size for management and protection of wildlife. Four different
sites were chosen in Syrian coast, which considered the most important ar
tificial lakes.
Point counts method was used in bird survey in November, December, January, February,
March in 2011. 15 waterbird species were recorded belonging to 9 family and 6 order.
Wading birds were the main component of waterbird (60% of all species) in Syrian
coast. Populations size was 1 to 300 individuals. Diversity of birds and their Populations
were greatest in sites which are rich in food ( especially fish). The results showed a
difference in composition of bird communities in studied sites.
This study aimed at determining some indicators of water quality in Lattakia dams within ten years (2002-2011).The indicators(pH, Electrical conductivity,Total Hardness, ca Hardness, Mg Hardness, Alkalinity, Phenol Alkalinity) in five dams (Balloran,
16 Tishreen, Al-thawra, Al-safarkia and Al-hweez) were studied. The resultsshowed thatpH, Electrical conductivity,Total Hardness, Alkalinity, Phenol Alkalinity, were within the allowed limits according to Syrian standards for drinking and irrigation water and which indicate the presence of pollution water sources.
