Studied the distribution coefficient of elemental copper and lead contaminants in the aqueous phase using a Bi-phase system: solid phase (the sands of Palmyra) and liquid phase (water containing the former two elements), where they were sampling sand samples from different regions in Palmyra to investigate for possible use as an adsorbent for elemental copper the lead from contaminated water, and after adjustment for certain transactions from time mixing phases, granular size, concentration of hydrogen ions, the concentration of the contaminated ingredient, the concentration of rival element (calcium) in addition to the ratio v / m in order to get the best rate for removal of these elements. The removal rate of copper componentamounted to 99.9% using four sites samples of sand a Palmyra, (al qareaten - the third leg to pump crude oil T3 - Alhl field - the valley between Mount aldahek and Sokhna) For lead removal ratio stood at 76.35% for the qareaten and 87.75% of the station the third to pump crude oil and 95 0.0% of the field Alhl and 96.25% of the valley between Mount aldahek and Sukhna. The application of the conditions that we have obtained in the laboratory to industrial water samples from the water income for the unity of treatment in Banias refinery and Water Company Drinaj of the Syrian Company for Oil Transport and the ratio of the removal of lead in the four samples ranging from ( 97.79 - 100)% for water Banias Refinery Company ranged between (83.89 - 88.08)% for water Syrian Company for Oil Transport, while the percentage of removal of the copper in the four samples ranging from (96.52 - 99.37)% for water Banias refinery Company and ranged ratio remove copper from the Syrian Company for Oil Transport water between (82.66 - 96.28)% in four samples.

تتناول هذه الدراسة البحث في معامل التوزع لعنصري النحاس والرصاص في نظام ثنائي الطور يتكون من طور صلب (رمال تدمر) وطور سائل (مياه صناعية ملوثة). تم جمع عينات رملية من مناطق مختلفة في تدمر لدراسة إمكانية استخدامها كمادة ماصة لإزالة النحاس والرصاص من المياه الملوثة. تم ضبط عدة معاملات مثل زمن خلط الطورين، الحجم الحبيبي، تركيز شوارد الهيدروجين، تركيز العنصر الملوث، تركيز العنصر المنافس (الكالسيوم)، والنسبة v/m للحصول على أفضل نسبة إزالة. أظهرت النتائج أن نسبة إزالة النحاس بلغت 99.9% في جميع العينات، بينما تراوحت نسبة إزالة الرصاص بين 76.35% و96.25%. عند تطبيق الشروط المخبرية على عينات مياه صناعية، تراوحت نسبة إزالة الرصاص بين 83.89% و100%، ونسبة إزالة النحاس بين 82.66% و99.37%. خلصت الدراسة إلى أن رمال تدمر يمكن استخدامها بفعالية لإزالة النحاس والرصاص من المياه الملوثة بتكاليف منخفضة.
Critical review
دراسة نقدية: تقدم هذه الدراسة إسهاماً مهماً في مجال معالجة المياه الملوثة باستخدام مواد طبيعية متوفرة محلياً. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة تركز بشكل رئيسي على النحاس والرصاص، بينما يمكن أن تكون هناك عناصر أخرى تحتاج إلى معالجة مماثلة. ثانياً، لم يتم التطرق إلى تأثير العوامل البيئية الأخرى مثل درجة الحرارة والضغط على كفاءة الامتزاز. ثالثاً، الدراسة لم تقدم تحليلاً اقتصادياً شاملاً لتكلفة استخدام الرمال مقارنةً بالمواد الأخرى المتاحة. وأخيراً، يمكن أن تكون هناك حاجة لمزيد من الدراسات الميدانية لتأكيد النتائج المخبرية في بيئات حقيقية.

The changes in coefficient of distribution of lead and cupper has been studied in system with two phases, liquid water contaminated with lead and copper-solid (natural Phosphate of Syria) correlation of the following factors: Time of mixing phases, size of the developed steel ,change the values of PH ,concentration of elemental lead and concentration of element capper ,the concentration of calcium as a competitor to the occupation of sites available on the solid phase, the ratio V\m presents the water phase size on the mass of phase ,the Percentage removal of lead from aqueous samples prepared in the laboratory91,57-99,95% were the best conditions for a vast proportion removed can be summarized as follows: PH=[6,63-10,11], Time of mixing phases =60 minutes and V/m=1000. The Percentage removal of copper from aqueous samples prepared in the laboratory 95,27 -99,96 % were the best conditions for a vast proportion removed can be summarized as follows: PH= [7,89-11,01] , Time of mixing phases =60 minutes and V/m=1000. Ideal conditions have been applied that were obtained according to laboratory tests on water samples from industrial input to Banias refinery and water samples from industrial drainage to Syrian company for oil transport after Removal for lead was( 100%,99 %). Removal for copper was( 100%,98 %) .
Green chemistry requires concepts and industrial ecology using natural systems to rid industrial water flow from heavy metals, which effects badly on health and environment. For this purpose, the changes in coefficient of distribution of mercury has been studied in system with two phases, liquid (water contaminated with mercury) - solid (metal pyrite) correlation of the following factors: Time of mixing phases, size of the developed steel, change the values of pH, concentration of elemental mercury, the concentration of calcium as a competitor to the occupation of sites available on the solid phase, the ratio V / M presents the water phase size on the mass of phase, which reflects the remaining time of water phase in the solid phase. The results show that pyrite can be proposed as safe environmental solution for purification of water phase of mercury, after controlling for some operation transactions.
studied the elimination of lead using natural zeolite by studding the the best conditions to removal lead in a system with two phase: liquid (contaminated water with lead)-solid (natural zeolite), correlation of the following factors: time of mixin g phase, granular size of solid phase, change of pH values, concentration of the calcium element as a competitor element for the available sites for occupation on the solid phase, the ratio V/m represents the size of the aqueous phase to the mass of the solid phase and concentration of lead element. On the other hand, the possibility of using natural zeolite as a template for storaging dangerous materials such as lead, has been studied by changing water quality, pH and temperature. The results of this research show that and under the following experimental conditions: time of mixing=4hour, mix of granular size of solid phase, pH< 8, concentration of calcium = 20 ppm,V/m=100 and concentration of lead = 1000 ppm , the rate of lead removal range from 60% to 99%. On the other hand, the results of this research show that changing water quality has no impact on the ability of natural zeolite for storaging lead as a hazardous waste, while pH changes have minor effects on this ability of retention and an effect for the high temperatures on the template was also observed.
This research was carried out during the period 08/28/2012 - 07/29/2013 in order to determine the qualitative composition of Puffer Fishes (Tetraodontidae) in the marine water of Latakia. Fish samples were collected from three stations (Borj Islam , Al madina al riyadiah and Jableh), the total of fishes were / 255 / individuals. All fish individuals were classified, preserved and placed at the High Institute of Marine Research Laboratory, some biological factors of the collected fish (K%, GSI%,HIS%) were studied. Results had revealed the presence of five species of Puffer Fish belong to three genera of Tetraodontidae: Lagocephalus sceleratus, L. spadiceus, L. suezensis, Sphoeroides pachygaster, Torquigener flavimaculosus. S. pachygaster species (migratory species from the Atlantic Ocean to the Mediterranean Sea) has been recorded for the first time in the marine water of Syria. Results showed that L. suezensis were more coincidence species in the catch. The amounts caught of Puffer Fishes varied according to the stations; the highest was in Borj Islam. K% was almost similar in all species, while GSI% and HSI% varied according to the species and seasons.
The problem of drinking water scarcity exacerbates in some villages in Tartous governorate making water conservation a priority. The aim of this study is to identify the patterns and practices of household water consumption of a sample of water su bscribers in Tartous governorate in order to determine the procedures through which to rationalize the consumption of drinking water. For this purpose, a survey of 150 household water subscribers was conducted. The answers were then subjected to a statistical analysis. The results indicated the presence of a high percentage of those who follow the procedures for rationalizing the consumption of water within the sample (95.3%), and a low percentage of those who have the techniques for reducing water consumption (4.7%). The majority of those surveyed (87.3%) objected to increasing the price of water as a measure to reducing water consumption. The study revealed that there is a good aqueous awareness in the governorate on which one can rely in rationalizing the consumption of drinking water through awareness campaigns.
