This study was conducted to determine some heavy minerals in different types of canned meat sold in the domestic market. Most of those cans were imported and processed in different countries and they have different brands. The chosen samples after ashing were prepared by using concentrated extra pure Nitric and Hydrochloric acids .The ratios of the minerals )pb , Cd , Ni , Zn , Cu , Mn , Fe ( were determined by Atomic Absorption Spectrophotometry , and the content was expressed as (p.p.m) wet weight. It was observed that the levels of Lead, Iron, and Cadimum, in all different samples were higher than the permitted limlts according to the Syrian Standards . The Cu level in both , tuna and sardine was within the permitted limits, but it was higher in the chicken Lunchoen. The level of Zinc was within the permitted limits according to the Syrian standards. The highest ratio of Lead was observed in the sardine imported from Morocco which was 8.765 p.p.m and in the Lunchoen processed in Syria which was 5.18 p.p.m ,and both ratios are much higher than the permitted limits according to the Syrian Standards.

Research summary
أجريت هذه الدراسة لتحديد نسب بعض المعادن الثقيلة في أنواع مختلفة من معلبات اللحوم المتوفرة في السوق المحلية السورية. شملت الدراسة عينات من معلبات الطون، السردين، والمرتديلا المصنعة في بلدان مختلفة. تم تحضير العينات باستخدام حمض الآزوت المركز وحمض كلور الماء المركز، وتم قياس نسب المعادن باستخدام جهاز الامتصاص الذري. أظهرت النتائج أن نسب الرصاص، الحديد، والكادميوم في جميع العينات كانت أعلى من الحدود المسموح بها وفق المواصفة القياسية السورية. بينما كانت نسب النحاس والزنك ضمن الحدود المسموح بها، باستثناء معلبات المرتديلا التي تجاوزت فيها نسبة النحاس الحدود المسموح بها. كانت أعلى نسبة للرصاص في عينات السردين المصنعة في المغرب، وأعلى نسبة للحديد في عينات المرتديلا السورية. توصي الدراسة بضرورة إجراء مراقبة مستمرة لمستويات المعادن الثقيلة في الأغذية لضمان سلامة المستهلك.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة جداً في سياق ضمان سلامة الأغذية المتوفرة في السوق المحلية، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين عينات من معلبات اللحوم المصنعة محلياً بشكل أكبر لمقارنة النتائج بشكل أوسع. ثانياً، لم تتطرق الدراسة إلى تأثيرات هذه المعادن على الصحة البشرية بشكل مفصل، وهو جانب مهم يجب أخذه في الاعتبار. أخيراً، كان من الممكن تقديم توصيات أكثر تفصيلاً حول كيفية تقليل نسب هذه المعادن في المنتجات الغذائية.
Questions related to the research
  1. ما هي المعادن الثقيلة التي تم قياسها في الدراسة؟

    تم قياس نسب الكادميوم، النيكل، الرصاص، الحديد، النحاس، والمنغنيز في العينات المأخوذة.

  2. ما هي أعلى نسبة للرصاص وأين وجدت؟

    أعلى نسبة للرصاص كانت في عينات السردين المصنعة في المغرب، حيث وصلت إلى 8.765 جزء في المليون.

  3. هل كانت نسب الزنك ضمن الحدود المسموح بها؟

    نعم، كانت نسب الزنك ضمن الحدود المسموح بها في المواصفة القياسية السورية والعالمية.

  4. ما هي التوصيات التي قدمتها الدراسة؟

    أوصت الدراسة بضرورة إجراء مراقبة مستمرة لمستويات العناصر الثقيلة والسامة في الأغذية لضمان السلامة الغذائية وجودة الغذاء المصنع.

This study has been conducted to identify the levels of heavy metals (lead, cadmium, nickel, cobalt, copper, iron, manganese, and zinc) in the following spices: Nutmeg, turmeric, cinnamon, ginger, cardamom, nigella sativa, black pepper, cumin, coriander, curry, and mixed spices.
This study was conducted to identify the levels of heavy metals (lead, cadmium, mercury, nickel, copper, iron, zinc) in the following processed local and imported meat: Sardine (canned full), Tuna (canned chunks), Hammour (frozen full), Euphrates Fis h (frozen full), fish produced at Qattinah Lake in Syria (frozen full) , lamb (frozen ground), beef (frozen ground), lamb sausage (frozen full), beef sausage (frozen full), sausageproduced in Netherlands (frozen stuffed), lamb liver (frozen full), broiler chicken liver (frozen full), broiler chicken (frozen full), chicken mortadella (canned), beef mortadella (canned), chicken mortadella (canned) produced in Netherlands. Heavy metal concentrations were identified in the samples of the studied meat by atomic absorption spectrometer. The concentrations taken in the wet weight measured in (ppm) were as follows: lead values range between (0.1–5.61),cadmium(0.01–2.02), mercury (0.14 –79.01), nickel (0.11 - 0.82), copper (0.24 – 6.89), iron (1.01 - 91.03), zinc (8.14 - 45.5). It was noticed that in some of the studied samples of the imported and locally-processed meat the levels of lead, cadmium, mercury, and nickel were above the levels permitted by WHO (World Health Organization) and by FAO (Food and Agriculture Organization).While the concentrations of copper, iron, and zincwere belowthelevels permitted.
The study focused in this research to determine the trace of some heavy metal elements (Copper Cu, Cadmium Cd, Lead Pb) in some types of marine macroalgae scattered on the shore of the city of Banias during 2014, using atomic absorption spectrosco py (technology flame Flame- AAS). The results indicate that the concentrationsofeach of Copper, Cadmium and Lead have a link with macroalgae types, sampling sites from direction, and Source of pollution on the other hand; it was observed that the accumulation of heavy metals in both of Sargassum vulgare (browen algae) and Enteromorpha linza (green algae) was more than red algae. Copper concentration ranged between 1.291 ppm and 11.716 ppm in the studied species, Reaching the highest value in the Enteromorpha linzaalgae and the lowest in Sargassum vulgarealgae, the highest value of Lead element was (59.354 ppm) in Enteromorpha linzaand the lowest value of it was (6.46 ppm) in Ulva fasciata, While the highest values of the element Cadmium recorded (10.457 ppm) in Enteromorpha linza and the lowest (0.666 ppm) in Ulva fasciata.
The concentrations of Copper (Cu) and Zinc (Zn) in samples of some spices available at some local markets in Syria were determined, after nitric digestion, using Atomic Absorption Spectrometry. The study showed differences in metal concentrations according to the edible part. Studied heavy metals were present in all samples at different levels. The concentration of Copper (Cu) and Zinc varied from trace to higher concentration. The maximum level of Copper (Cu) in the spices samples was 0.668 mg/kg. The maximum level of Zinc (Zn) in the spices samples was 2.523mg/kg. The analytical results obtained for the heavy metals indicate that the Copper and Zinc were present in all samples at concentration well below the acceptable daily intake recommended by the World Health Organization.
This study deals with the determination of the quantity of solid dust particles deposed on the leafs of some trees along Syrian coast and the concentration of some heavy metals in it (Zn, Fe, Pb, Cu, Ni, Cd, Co, Mn) .Some sites near to human and in dustrials activities , and others near to agriculture activities , and others relatively far from pollution sources has been selected. The results showed that the quantity of solid dust particles on leafs trees and concentration of heavy metals in it such as (Pb, Ni, Cd, Co) increasing near the industrials activities and dense traffic, and decreasing in the sites that relatively far from of pollution sources. However Cypress trees attach solid quantities more than Pride of china, following Rever red gum and Blue-leafed wattle and Oleander, and the Palm tree come in the last.
