The research has been conducted in different sites in lattakia, Alhamra and alsabahia villages of Rabea and Aen alzarqa of Mashqeta. 14 cases of precipitation was marked which caused runoff and water erosion of soil during the research (seasonal rainfall in 2011/2012). Samples of rain water of every precipitation case were collected. by using rain gauges that were installed in the research sites. After that, samples were moved to the laboratory. The pH was determined after that the samples were analyzed by using an ion chromatography device(IC).

Research summary
تناولت الدراسة الخصائص الكيميائية لمياه الأمطار في مواقع مختلفة من محافظة اللاذقية، وهي قريتي الحمراء والصباحية التابعة لناحية ربيعة، وقرية عين الزرقا التابعة لبلدة مشقيتا. تم تسجيل 14 حادثة هطول مطري خلال الموسم المطري 2011/2012، وتم جمع عينات من مياه الأمطار لكل هطول مطري باستخدام مقابيس مطرية، ثم نقلت العينات إلى المختبر لتحليلها باستخدام جهاز الكروماتوغرافيا الشاردية (IC). أظهرت النتائج أن مياه الأمطار في المنطقة المدروسة تتميز بطبيعتها القلوية، حيث تراوحت درجة الـ pH بين 7.1 و 7.8. كما بينت النتائج تأثير الرياح الربيعية المحملة بغبار التربة على بعض الخصائص الكيميائية لمياه الأمطار، حيث سجلت أعلى تركيزات لشوارد الكبريتات والكلور والصوديوم والأمونيوم خلال فصل الربيع. ولم تظهر فروق معنوية في تركيز شاردتي الكالسيوم والمغنزيوم في مياه الأمطار المسجلة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لفهم الخصائص الكيميائية لمياه الأمطار في منطقة ريفية مثل محافظة اللاذقية، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الممكن توسيع نطاق الدراسة ليشمل مواقع حضرية وصناعية لمقارنة النتائج. ثانياً، لم يتم التطرق بشكل كافٍ إلى تأثير الأنشطة البشرية المحتملة على تركيز الشوارد المختلفة في مياه الأمطار. وأخيراً، كان من الممكن استخدام تقنيات تحليلية إضافية لتعزيز دقة النتائج وتوفير صورة أكثر شمولية عن التركيب الكيميائي لمياه الأمطار.

This research aimed to study some chemical characteristics of rainwater in the region located at the East of Baniyas area the coastal region of Syria . Baniyas area contain complex of industrial facilities including oil refinery, electrical power g eneration station and oil transportation. pH values, concentration of trace metals (Pb, Cu, and Cd) and major ions (Ca2+, Mg 2⁺, Na⁺, NH₄⁺, K⁺,SO₄2-, NO3⁻, Cl⁻, F⁻) were determined during the period from October 2012 to May 2013. Samples were collected from 15 sites differ in distances from the emissions sources. Most of samples have normal pH value. The pH values decreased while the concentration of SO₄2-, NO3⁻, and trace metals Pb, Cu, Cd increased significantly by getting closer to emission source up on 2500m. The changes of the chemical characteristics of rainwater were significant.
The big value of dams in the Syrian coast comes from using them for irrigation and sometimes as source of potable water. This study aimed to determine some chemical indicators of water quality in Lattakia dams during ten years (2002-2011). The conce ntrations of ions (Cl-1, SO4-2, NO2-1, NO3-1, PO4-3, K+1, Na+1) in five dams (Balloran, 16 Tishreen, Al-thawra, Alsafarkia and Alhweez) were studied. The results indicated that most of the ions showed significant difference in concentrations during 2002-2011.The ions concentrations in most studied dams increased. The increase related to characteristics of dams (location, capacity, the activities located around the dam…).
In this study, iron chloride solution ١٠٪ was used as absorbance matter which absorbs all dyes and the organic substances during its precipitation . The accumulation of these wastes in nature is considered to be a serious source of pollution and h ealth hazard. We determined the optimal pH and the optimal dose of a minimom number of the reagent used as well as the water of dyehouse baths, and we compared the difference between using iron chloride and aluminium sulfate .We adopted the experimental observation in measuring the results and the strength of absorption within the spectrofield in a wave length of ٣٥٠ – ٧٥٠ nanometer .
In this study the urban system of the governorate of Lattakia has been examined through the applicability of measurements of the equality of spatial distribution patterns of cities (Demangeon Index and Lorenz curve), and those of Primacy and cities size distribution patterns (the Law of Primate city of Mark Jefferson, 1939, the Index of Primacy of Stewart, and the hierarchical order of city through the Rank-size Rule - George, K. Zipf, 1949). It has been identified on the size of the imbalance equilibrium in the system urban cities through Urban Isostastic Index. The results of the study showed a clustered patterns of the spatial distribution of urban centers according to the value of Demangeon Index (0.42) and unequal distribution of urban population to the cities (75% of urban population are distributed on 15% of cities). It showed also a great domination of the primate city of Latakia on the urban system where the population volume was (6.1) time bigger than the volume of the next cities according to Primacy Index; a great decrease of the real value of the next cities comparing with the theoretical value of Law of Primate City (16.4%) against (67%), and disability to applying the Rank-size Rule.
This research was performed to study the effect of sewage water on the surface water of the Addelbeh Valley stream, and groundwater on both sides of the stream in Tartous Cement Factory area. Water samples were taken from the factory water outlet and Addelbeh Valley water to study the content of pollutants. We also took groundwater samples from selected wells on both sides of the waterway in the studied area. We repeated that process every two months for a full hydrological cycle from July 2013 to May 2014. We found a great increase in content of the industrial drainage water include oils and heavy metals especially iron, copper and zinc. For example: iron concentration in sewage water exceeded 150 mg/l in all samples. Besides sewage water and stream water contained high concentrations of ammonia and nitrite versus low concentration of nitrate, unlike water wells samples. The study revealed increased EC and salts concentration markedly in wells water due to its adjacency to the sea.
