Research summary
تتناول هذه الدراسة حركية ادمصاص الكادميوم والرصاص في التربة باستخدام تجربة أعمدة التربة. تم استخدام تركيزات محددة من الكادميوم والرصاص ودرجات مختلفة من الرقم الهيدروجيني لدراسة تأثير هذه العوامل على توزيع وانتقال هذه المعادن في التربة. أظهرت النتائج أن ادمصاص المعادن الثقيلة يتركز في الطبقة السطحية من التربة (0-20 سم) وأن الرقم الهيدروجيني المنخفض (pH=5.5) يقلل من تركيز الكادميوم والرصاص المتاحين، مما يزيد من حركتهما مع عمق التربة. كما بينت الدراسة أن الرصاص أشد ارتباطاً بالتربة من الكادميوم.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لفهم تأثير الرقم الهيدروجيني على ادمصاص المعادن الثقيلة في التربة، ولكن يمكن تحسينها من خلال توسيع نطاق التجارب لتشمل أنواع مختلفة من التربة وظروف بيئية متنوعة. كما يمكن تضمين دراسات ميدانية لدعم النتائج المخبرية. بالإضافة إلى ذلك، يمكن تحسين تحليل البيانات باستخدام تقنيات إحصائية أكثر تقدماً لتقديم نتائج أكثر دقة وموثوقية.
Questions related to the research
  1. ما هي تأثيرات الرقم الهيدروجيني على ادمصاص الكادميوم والرصاص في التربة؟

    الرقم الهيدروجيني المنخفض (pH=5.5) يقلل من تركيز الكادميوم والرصاص المتاحين ويزيد من حركتهما مع عمق التربة.

  2. ما هو العمق الذي تتركز فيه المعادن الثقيلة في التربة حسب الدراسة؟

    تتركز المعادن الثقيلة في الطبقة السطحية من التربة بعمق 0-20 سم.

  3. كيف يؤثر الرقم الهيدروجيني على ارتباط الرصاص بالتربة مقارنة بالكادميوم؟

    الرقم الهيدروجيني المنخفض يزيد من حركة الكادميوم والرصاص، ولكن الرصاص يظهر ارتباطاً أشد بالتربة مقارنة بالكادميوم.

  4. ما هي التوصيات لتحسين هذه الدراسة؟

    توسيع نطاق التجارب لتشمل أنواع مختلفة من التربة وظروف بيئية متنوعة، وتضمين دراسات ميدانية، واستخدام تقنيات إحصائية أكثر تقدماً لتحليل البيانات.

The study investigated the possibility of removing heavy metal ions (Cd, Pb) from aqueous solutions using adsorption method on the citrus peel (orange), which is a solid waste available in abundance especially in the Syrian coast as well as easy to use at low cost. The optimal conditions for the simultaneous adsorption of the ions (Cd 2+, Pb 2+) on the surface of orange peel (dry, soft) were determined.The concetration of ions was determined using (DPASV) method Which is characterized by Sensitivity and high accurawcy. The results showed that the optimum adsorption conditions were at pH = 5 , equleibrium time = 60 min, and the initial concentration is ( C0 = 50-200) ppm,The application of the Langmuir and Frienlish models showed that Frienlish model is best fited for expressing the adsorption of Pb ions on the surface of dry and soft orange peel and for expressing the adsorption of Cd ions on the surface of soft orange peel , Langmuir model is best fited for expressing the adsorption of Cd ions on the surface of dry orange peel. The method applied its selected terms to realistic samples of processed and industrial waste water, which showed a unique response as a purification method for the water media.
The sludge of wastewater used in agriculture processes, in order to knew the effect of its application on soil and plant contents from zinc and cadmium, Hordeum vulgare L. was planted by using graded amounts of sludge to the soil for two years, fou r treatments were used: o kg/pot (control), 2, 4, 6 ton/ha (with 5 erplicates for each treatment), concentrations of zinc and cadmium in soil, roots, straw, and grain in all treatments were measured. Results showed that the application of sludge improve the physical and chemical properties of the soil, the concentration of zinc and cadmium in the soil were 164.66 μg/g, 324.22 ng/g, respectively, in 60 ton/ha treatment. Concentration of Zn increased significantly and showed positive correlation with the amount of sludge, the highest concentration of Zn was in root of plant in comparison with other parts of plant, in all treatments, it was 69.3 μg/g in the root while it was 45.15, 38.2 μg/g in straw and grain respectively, in 0.6 kg/pot treatment. Concentration of cadmium increased significantly in 0.6 kg/pot treatment in comparison with control, the highest concentration was in the root of plant in comparison with other parts of plant. This study showed that Hordeum vulgare L. doesn't accumulate zinc and cadmium because it´s concentration in roots was higher than in straw and grain. Concentration of Zn and Cd still within permissible limits in the soil and plants in all treatments.
In this study, the concentration of Pb and Cd was determined in some agricultural products in order to compare this concentration and to know the capacity of these products to accumulate these two elements. The samples were digested by nitric acid and the elements were determined by the atomic absorption spectroscopy. The results showed that the concentration of lead and cadmium in protected products was less than the concentration in unprotected products, and the concentration of lead was more than the cadmium, these results can be explained by the extensive use of lead and the unprotected agriculture products were exposed to the air pollution more than the protected products.
This study estimated the levels of lead and cadmium in 12 chocolate and cocoa samples from latakia markets by atomic absorption spectrometry . Most of the samples, were well known Syrian trademarks. The results showed that concentration of lead in samples of dark chocolate ranged between 0.061 and 0.49 mg\ kg ,and in samples of cocoa between 0,10 and 0,51 mg\ kg, but it was much less 0.01 - 0. 16 mg\ kg in white chocolate and Imported chocolates. concentration of cadmium in samples of dark chocolate ranged between 0.01 and 0.24 mg\ kg and in samples of cocoa between 0.03 and 0.231 mg\ kg. but it was also less in white chocolate and imported chocolates 0.01 - 0.051 mg\ kg. The results indicated that dark chocolates have higher concentrations of lead and cadmium than white chocolates and that the levels of lead and cadmium are generally higher than the common levels in developed countries ,and thus. might be a significant source of lead and cadmium ingestion, Raw materials should be checked before use for metal contents in order to decrease the concentrations of these metals in final chocolate products..
The aim of the present study was to determine the levels of lead and cadmium in the meat, liver and kidney of sheep exposed in the local markets of the city of Latakia, and to compare the results with those reported by other countries and with the maximum acceptable levels for human consumption, Lead and cadmium were determined by atomic absorption spectrometry (AAS). The mean concentrations of lead in meat, liver and kidney were 0.043, 0.284 and 0.118 mg/kg fresh weights, respectively, while mean concentrations of cadmium were 0.017, 0.173 and 0.252 mg/kg fresh weights, respectively. Statistical analysis showed a significant difference in lead and cadmium concentrations between liver and kidney and in meat.
