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.

Research summary
تتناول هذه الدراسة تحديد تركيز الرصاص والكادميوم في بعض المنتجات الزراعية المحمية وغير المحمية في المنطقة الساحلية السورية. تم جمع عينات من البندورة، الفليفلة، الملفوف، والبقدونس، وتحليلها باستخدام تقنية الامتصاص الذري بعد تهضيمها بحمض الآزوت. أظهرت النتائج أن تركيز الرصاص والكادميوم في المنتجات الزراعية المحمية أقل من تلك غير المحمية، وذلك بسبب تعرض الأخيرة لتلوث الهواء الجوي. كما أظهرت النتائج أن تركيز الرصاص في العينات كافة أعلى من تركيز الكادميوم، وهي ضمن الحدود الطبيعية في مثل هذه المنتجات الزراعية. تهدف الدراسة إلى تسليط الضوء على تأثير التلوث الهوائي على تراكم العناصر الثقيلة في المنتجات الزراعية، وتوصي بمتابعة الدراسات لتشمل ملوثات أخرى عضوية ولاعضوية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في تسليط الضوء على تأثير التلوث الهوائي على تراكم العناصر الثقيلة في المنتجات الزراعية. ومع ذلك، يمكن توجيه بعض النقد البناء لتحسين الدراسة. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل مناطق جغرافية أخرى لتقديم صورة أكثر شمولية. ثانياً، لم تتناول الدراسة تأثير هذه التراكيز على صحة الإنسان بشكل مباشر، وهو ما يمكن أن يكون له أهمية كبيرة. أخيراً، كان من الممكن استخدام تقنيات تحليلية أخرى بجانب الامتصاص الذري لتأكيد النتائج وزيادة دقتها.
Questions related to the research
  1. ما هي العناصر الثقيلة التي تم تحليلها في الدراسة؟

    العناصر الثقيلة التي تم تحليلها في الدراسة هي الرصاص والكادميوم.

  2. ما هي التقنية المستخدمة لتحليل تركيز العناصر الثقيلة في العينات؟

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.
Carried out a laboratory experiment in order kinetics study of adsorption of cadmium and lead in the soil, using soil columns experiment, with the use of concentration 26.25 mg / l for cadmium, and 27.81 mg / l for lead, and two degrees of pH 5.5, 0.7, with the use of five parameters.
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.
A total of 294 samples of raw-unpasteurized bovine milk and variety of dairy products (hard cheese, sweet cheese, cream cheese and cream), were collected from local markets in Lattakia city as well as 44 samples of used water (clear potable water collected before used in cheese preparing processes) and preserving water (turbid water collected from hard cheese preserving tanks). All samples were analyzed for E.coli O157: H7 detection.
