درس معامل التوزع لعنصري النحاس و الرصاص كملوثات في الطور المائي باستخدام منظومة ذات طورين: طور صلب (رمال تدمر) و طور سائل (مياه تحوي على العنصرين السابقين), حيث تم اعتيانعينات رملية من مناطق مختلفة في تدمر للتقصي عن إمكانية استخدامها كمادة مازه لعنصري النحاس و الرصاص من المياه الملوثة, و ذلك بعد ضبط بعض المعاملات من زمن خلط الطورين, الحجم الحبيبي, تركيز شوارد الهدروجين, تركيز العنصر الملوث, تركيز العنصر المنافس (الكالسيوم) بالإضافة إلى النسبة v/m بغية الحصول على أفضل نسبة إزالة لهذه العناصر. بلغت نسبة الإزالة لعنصر النحاس 99.9% باستخدام عينات أربع مواقع للرمال التدمرية و هي: (القريتين – المحطة الثالثة لضخ النفط الخام – حقل الهل – الوادي بين جبل الضاحك و السخنة). أما بالنسبة للرصاص, فقد بلغت نسبة الإزالة 76.35% للقريتين و 87.75% للمحطة الثالثة لضخ النفط الخام و 95.0% لحقل الهلو 96.25% للوادي بين جبل الضاحك و السخنة بعد ضبط جميع المعاملات. تم تطبيق الشروط التي حصلنا عليها مخبرياً على عينات مياه صناعية من مياه الدخل لوحدة المعالجة في شركة مصفاة بانياس و مياه دريناج من الشركة السورية لنقل النفط و كانت نسبة الإزالة للرصاص في العينات الأربع تتراوح بين (%97.79 – 100) بالنسبة لمياه شركة مصفاة بانياس و تراوحت بين %( 83.89 - 88.08) بالنسبة لمياه الشركة السورية لنقل النفط بينما كانت نسبة الإزالة للنحاس في العينات الأربع تتراوح بين %(96.52 – 99.37) بالنسبة لمياه شركة مصفاة بانياس و تراوحت نسبة إزالة النحاس من مياه الشركة السورية لنقل النفط بين %(82.66 – 96.28) في العينات الأربع.
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.

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.
