يهدف هذا البحث إلى دراسة أهم مؤشرات تلوث المياه المسببة للإثراء الغذائي في بحيرة سد الباسل، و ربطها بمصادر التلوث المتركزة على ضفاف البحيرة، و المتمثلة بمياه الصرف الصحي غير المعالجة من القرى المجاورة، و مياه الصرف الزراعي المحملة بالأسمدة المختلفة التي تصل إلى البحيرة مع مياه الأمطار الوافدة من الأراضي الزراعية المحيطة بالمنطقة. و هذه المؤشرات هي تراكيز الفوسفور الكلي، و تراكيز النتروجين الكلي. تمّ أخذ العينات و تحليلها من أربعة مواقع (S1-S2-S3- S4)، خلال دورة هيدرولوجيّة كاملة ابتداءً من كانون الثاني (2016) حتّى كانون الأول .(2016) و نتيجة الدراسة تبين أنّ البحيرة شديدة الإخصاب بحسب المؤشرين (TN- TP)، و هذا يدل على أنّ البحيرة تتأثّر بالملوثات التي تصادفها و خاصة ملوثات مياه الصرف الصحي، و تمّ تعيين العنصر المحدد لنمو الطحالب من خلال معرفة النسبة ما بين النتروجين الكلي و الفوسفور الكلي حيث تبين أنّ النسبة TN/TP أكبر من 10 و بالتالي فإن الفوسفور الكلي هو العنصر المحدد لنمو الطحالب في بحيرة سد الباسل.
This research aims at studying the most important indicators of water pollution leading to nutrient increase (eutrophication) in AL- Basel Dam Lake, and connecting them with pollution sources represented by untreated sewage water and agricultural drainage water, including rain water coming from the lands surrounding the lake. Among the most important of these indicators are total phosphorus (TP) and total Nitrogen (TN). Samples were taken and analyzed from four sitesof the lake (S1, S2, S3, S4) were conducted periodically. The work continued to conduct tests for full hydrological cycle as of January (2016) until December (2016). The study showed that the lake was highly fertilized according to the (TN- TP) this indicates that the lake is affected by the pollutants it encounters, especially the wastewater pollutants. The specific component of algal growth was determined by knowing the ratio between total nitrogen and total phosphorus. The TN / TP ratio was greater than 10, so total phosphorus is the specific component of algal growth in the Basel DamLake.

Research summary
يهدف هذا البحث إلى دراسة مؤشرات تلوث المياه المسببة للإثراء الغذائي في بحيرة سد الباسل، وربطها بمصادر التلوث مثل مياه الصرف الصحي غير المعالجة والمياه الزراعية المحملة بالأسمدة. تم أخذ عينات من أربعة مواقع في البحيرة وتحليلها خلال دورة هيدرولوجية كاملة من يناير إلى ديسمبر 2016. أظهرت النتائج أن البحيرة شديدة الإخصاب وفقًا لمؤشري الفوسفور الكلي والنتروجين الكلي، مما يدل على تأثرها الكبير بالملوثات، وخاصة مياه الصرف الصحي. تم تحديد الفوسفور الكلي كالعنصر المحدد لنمو الطحالب في البحيرة. توصي الدراسة بمعالجة مياه الصرف الصحي وترشيد استخدام الأسمدة الكيميائية لتحسين جودة المياه.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لأنها تسلط الضوء على مشكلة بيئية حيوية تؤثر على جودة المياه في بحيرة سد الباسل. ومع ذلك، يمكن توجيه بعض النقد البناء لتحسين البحث. أولاً، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت تحليلاً لمزيد من العناصر الكيميائية والبيولوجية التي قد تؤثر على جودة المياه. ثانياً، لم يتم تقديم حلول عملية واضحة يمكن تنفيذها على الفور لتقليل التلوث، مما يجعل التوصيات أقل فعالية. وأخيراً، كان من الأفضل تضمين مقارنة مع بحيرات أخرى في المنطقة لتقديم صورة أكثر شمولية عن الوضع البيئي.

The research aims to determine the water Quality Index for the Lake of 16 Tishreen Dam. To achieve
this aim, we have carried out different periodical physic-chemical and bacterial measurements on the lake
water. The samples were taken at five sites
along the lake for a period of one complete year. The indicators
that have been measured are: Temperature, Turbidity, PH, EC, DO, BOD5, NO3, NO2, NH4 ,PO4, F.C.
Measurement results were represented diagrammatically, and compared with the Syrian Specification
Standards for portable Water. The lake was classed according to these Indices: Malays quality index,
Canadian Indices (NSFWQI), (NEWWQI). The Lake was Classed according to these indices as following:
from third grade at all locations (Malays Index), from second grade at the middle lake and from a third grade
to all other locations (NSFWQI), and from second grade at all locations (NEWWQI). According to this
indices the water is not good for drinking and needs treatment. The Productivity of the lake was determined.
The Lake is Eutrophic according to TN,TP in the middle but Hypertrophic according to TN,TP in all other
locations.

This research aims to evaluate the water quality of the Al-Sain lake which feeds
mainly the Lattakia city and a part of the Tartous city of drinking water purpose.
In this paper, we study a group of physical and chemical factors for the water of th
e
Al-Sain lake during the years of available data (1991-2004-2007-2011), samples were
taken from four different locations according to the program approved by the concerned
staff to monitor and protect the lake, namely: (Lattakia water supply point, Tartous water
supply point, irrigation point, southern spring observatory), and we calculated the quality
index for drinking purposes using US approved methodology of National Sanitation
Foundation. Nine factors have been adopted: (dissolved oxygen, fecal coliforms, pH,
BOD5, temperature, phosphate, nitrates, turbidity, and total solids).
The research result showed that the classification of water quality was good in all
four monitoring points during the years 1991 and 2004, noting a significant improvement
of the quality in 2004, and decreases slightly during the years 2007 and 2011 for
monitoring points in the Lattakia water supply and irrigation points, but water quality still
keep maintain a good classification, while the quality of the water goes down within the
threshold of middle classification for the Tartous and southern spring observatory
monitoring point.
The study included 144 Free – living fish from the Lake of 16 Tishreen Dam, collected randomly during the period from 12/2011 until 11/2012, on monthly basis to detect the infection with Epistylis sp. and determine its distribution rate.
Fish sam
ples were: Cyprinus carpio L., Varicorhinus damascinus, Garra rufus, Tilapia zilli, and Liza abu. Tilapia zilli was the most prevalent in the lake of 16 Tishreen Dam.
The study revealed fish infection with Epistylis sp. on free – living fish in the Lake, with a total infection rate 22.22 % , mainly on Tilapia zillii (29.70 %) and then on mullet (2%);No infection with Epistylis sp. Was recorded on the other fish species. The infection with this ecto Epistylis sp. was recorded for the first time in Syria in our study.
The infection with Epistylis sp. was located on the skin, fins and gills. The highest infection rate was on the fins ( 42.34 %) , followed by skin (37.46 %) , and then by gills (1.87 %) .
The infection with Epistylis sp. had the highest rate in summer ; i.e. during high temperature , low concentration of dissolved oxygen , and slightly high value of BOD.
The study showed that, the water of 16 Tishreen Dam is relatively clean.
The study included 132 Free – living fish in Lake of 16 Tishreen Dam,
collected randomly during the period from 22/11/2011 until 22/10/2012, on
average once a month, for detecting the infection of parasitic copepoda, and
determine the distribution rate, and their effect on the fish productivity.
