Soil samples were collected from three sites located at distances (0, 1500, 3000)m along the road from the northern entrance of Daraa city. For each site, samples were collected from two depths, at three distances from the road axis and from the two sides of the road. Results showed that total and available lead concentrations in soil were higher in east than west side of the road due to the effect of the dominant westerly winds in the region. the differences were significant for the total and available lead concentrations at distances (0,1500)m, and (0,3000)m at the entrance of the city, the distances (5,25)m, and (5,50)m, at the distance from two road sides, and between the depths (0-15), (15-30)cm, whereas the differences were not significant for the total and available lead concentrations at distances (1500,3000)m at the entrance of the city, and (25,50)m at the distance from two road sides. There was a very strong correlation between the average total and available lead concentration.

Research summary
تتناول هذه الدراسة تقييم تلوث التربة بالرصاص في مدخل مدينة درعا الشمالي. تم جمع عينات التربة من ثلاثة مواقع مختلفة على طول الطريق من مدخل المدينة على مسافات 0، 1500، و3000 متر. تم جمع العينات من عمقين مختلفين ومن جهتين للطريق (الشرق والغرب). أظهرت النتائج أن تركيزات الرصاص الكلي والمتاح في التربة كانت أعلى في الجهة الشرقية مقارنة بالجهة الغربية بسبب تأثير الرياح الغربية السائدة في المنطقة. كانت الفروقات معنوية في تركيزات الرصاص الكلي والمتاح عند مسافات 0 و1500 متر، و0 و3000 متر من مدخل المدينة، وكذلك بين المسافات 5 و25 متر، و5 و50 متر من حافتي الطريق. كما كانت الفروقات معنوية بين العمقين (0-15 سم و15-30 سم). كان هناك ارتباط قوي بين متوسط تركيزات الرصاص الكلي والمتاح. تشير النتائج إلى أن التلوث بالرصاص يتأثر بشكل كبير بالبعد عن مصدر التلوث (مدخل المدينة) والبعد عن حافتي الطريق، وكذلك بعمق التربة والجهة بالنسبة للطريق.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة جداً لفهم تأثير التلوث بالرصاص على التربة في المناطق الحضرية، خاصة في مدخل مدينة درعا الشمالي. ومع ذلك، يمكن أن تكون هناك بعض النقاط التي تحتاج إلى تحسين. على سبيل المثال، يمكن توسيع نطاق الدراسة ليشمل فصول السنة المختلفة لمعرفة تأثير التغيرات الموسمية على تركيزات الرصاص. كما يمكن أن تكون هناك حاجة لمزيد من التحليل حول تأثير التلوث على النباتات والحيوانات في المنطقة. بالإضافة إلى ذلك، يمكن أن تكون هناك حاجة لمزيد من الدراسات حول تأثير العوامل الجوية الأخرى مثل الأمطار والرطوبة على توزيع الرصاص في التربة. بشكل عام، تعتبر الدراسة خطوة مهمة نحو فهم أفضل لتأثير التلوث بالرصاص على البيئة، ولكن هناك مجال للتحسين والتوسع في البحث.
Questions related to the research
  1. ما هو الهدف الرئيسي من هذه الدراسة؟

    الهدف الرئيسي من الدراسة هو تحديد تركيز كل من الرصاص الكلي والمتاح في ترب مدخل مدينة درعا الشمالي ومدى ارتباطهما بالبعد عن مدخل المدينة الشمالي والبعد عن حافتي الطريق والجهة بالنسبة للطريق وعمق التربة.

  2. ما هي الفروقات المعنوية التي تم العثور عليها في الدراسة؟

    تم العثور على فروقات معنوية في تركيزات الرصاص الكلي والمتاح عند مسافات 0 و1500 متر، و0 و3000 متر من مدخل المدينة، وكذلك بين المسافات 5 و25 متر، و5 و50 متر من حافتي الطريق. كما كانت الفروقات معنوية بين العمقين (0-15 سم و15-30 سم).

  3. ما هو تأثير الرياح على توزيع الرصاص في التربة؟

    أظهرت الدراسة أن تركيزات الرصاص الكلي والمتاح في التربة كانت أعلى في الجهة الشرقية مقارنة بالجهة الغربية بسبب تأثير الرياح الغربية السائدة في المنطقة.

  4. ما هي التوصيات المستقبلية التي يمكن أن تُستخلص من هذه الدراسة؟

    يمكن توسيع نطاق الدراسة ليشمل فصول السنة المختلفة لمعرفة تأثير التغيرات الموسمية على تركيزات الرصاص. كما يمكن إجراء مزيد من التحليل حول تأثير التلوث على النباتات والحيوانات في المنطقة، ودراسة تأثير العوامل الجوية الأخرى مثل الأمطار والرطوبة على توزيع الرصاص في التربة.

The aim of this study was to estimate the total amount of phenolic compounds of olive trees leaves (Olea europaea L.) as Biomarker for the assessment of lead air pollution at Banias area. Olive trees were selected as the predominant species in the study area. The samples were collected from 6 locations at different distances from the vicinity of the Banias refinery (0.1, 0.5, 2, 4, 6, 10) Km. The dominated wind in the region is western - southwesterly during the winter (March) and summer (September), The control was taken from an area about 20 km from the refinery to the north-east (al-Qardahah rural). The concentration of total phenolic compounds (TPC) during the summer was (45.6-70.85) mg GAE/g dw and in the control (40.4) mg GAE/g dw, and during the winter the content of TPC was (35.6-52.9) mg GAE/g dw and in the control (25.8) mg GAE/g dw. The concentration of Lead (Pb) in unwashed leaves during the summer was (0.879 – 2.170) ppm and in the control (0.005) ppm, whilst during the winter was (0.479-1.023) ppm and in the control (0.00083) ppm. The results showed significant differences in the concentration of total phenolic compounds and lead between sites (Anova test). High concentration of total phenols and lead in the summer compared to values in winter at all sites (t-test). The results also showed a negative correlation between the concentration of total phenolic compounds and lead with the distance from the refinery of Banias. Finally, The results showed that the TPC can be used as biomarker of lead air pollution in Banias area.
This study was conducted to evaluation of some marshes soil physical characteristics at south Iraq from studying soil properties and accounting the simple and multiple correlation coefficients and relation equations, from which we can predicted th e soil aggregate stability modules of rapture and soil bulk density. Three transacts were chosen, which cover all south Iraqi marshes, with selection of the larger marshes at every transect. The transects are: First toward Amara included marshes of Al-Msendak, Al-Saadiah and Al-Wadiah. Second toward Al- Nasiriah which included the marshes of Delmag, Ghumugaa and Al-hammar. Third toward Samawa which included the marshes of Al- Ramah and Lafti.

The study was carried out at Soil Research Center in the province of Daraa during 2011 in order to study some physical and moisture characteristics for cinnamon soil, which occupies (48000 km²), equivalent to 26% of the area of the Syrian Arab Rep ublic and represents the cultivation of growing field crops with a rainfall ranges between 150- 300 mm. The results showed that the mechanical analysis for soil referred that its texture is clay with a good ability to retain water, the field capacity rated between (30-38.85)%. The studied soil has high value of available water (38.93mm) and useful water (25.69mm) in the surface layer. The highest value of permanent wilting point and hygroscopic moisture was reached in the final depth in studied profile soil, It was also distinguished a high total porosity ranged between 51.78 and 55.59% with a good air porosity amounted to 9.38 - 15.47 % in different depths and with the decline to 5.51 % in the depth 30 - 45cm.
Inhabitants' increase in the governorate of Daraa has great effect on civil development, as it is the case in other governorates of Syria, this is quite evident in the increase of inhabitants in civil centers, and its horizontal extension continuo usly. Due to the importance of this subject, I studied it, where the research included a survey of its problem that the continuous inhabitants' increase has been the cause of the increase of the number and volume of civil centers during the period between 1970-2010, where the rate of civilization increased by 14.3% to 41.6% The number of inhabitants in the governorate is expected to reach (1.631.005) inhabitants in the year 2025. that's with an increase of 505.005 inhabitants. The research included its importance, objective and courses, the developed number of inhabitants in the governorate, and effective factors that affect it, with the increasing number of civil centers. In addition to studying indications of civil development such as education, health, culture, services, industry, housing, then discussed their problems and impediments, such as the increasing rates of inhabitants, the random housing, environmental pollution, then presenting future suggestions and solutions for them.
