Lead levels were determined in 52 baby food samples dedicated to feeding children from birth until the age of 12 months. These samples were consisting of dried cow's milk, rice, wheat, cereal, fruits in addition to samples of human milk. Samples were exposed to welt digestions and lead level was determined using graphite furnace atomic absorption spectrophotometer, and results were compared with the certified reference samples. Results indicated that that different levels of leads were determined in the samples studied and it was in the lowest concentration (5.72 μg/kg diet) in canned fruits and in the highest concentration (121.35 μg/kg) in cereal samples ranged. Other interface levels of leads were found in the other baby food and reached 20.41μg/L in human milk, 84.32 μg/kg of cow´s milk provided from for 0 to 6 months of age, 98.15 μg/kg of cow´s milk provided at age 6 to 12 months, and 92.62, 99.94 μg/kg in formulas containing rice and wheat, respectively. While formulas based on cereal had the biggest.

Research summary
تتناول هذه الدراسة تحليل مستويات الرصاص في 52 عينة من أغذية الأطفال المتاحة في سوريا، بما في ذلك حليب الأبقار المجفف، الأرز، القمح، الحبوب، الفواكه المعلبة، وحليب الإنسان. تم استخدام جهاز الامتصاص الذري بتقنية الفرن الغرافيتي لتحليل العينات بعد تحضيرها بواسطة التهضيم الرطب. أظهرت النتائج أن أقل متوسط لتركيز الرصاص كان في الفواكه المعلبة (5.72 ميكروغرام/كغ غذاء)، بينما كان أعلى تركيز في الأغذية المكونة من الحبوب (121.35 ميكروغرام/كغ غذاء). كما أظهرت الدراسة أن متوسط تركيز الرصاص في حليب الإنسان بلغ 20.41 ميكروغرام/ل، وفي الحليب المجفف للمرحلة العمرية الأولى 84.32 ميكروغرام/كغ، وللمرحلة العمرية الثانية 98.15 ميكروغرام/كغ. تشير الدراسة إلى أن مستويات الرصاص في أغذية الأطفال السورية مرتفعة مقارنة ببعض الدول الأخرى، مما يستدعي إجراء مسح وطني شامل لمراقبة مستويات الرصاص والعناصر المعدنية الثقيلة الأخرى في الأغذية.
Critical review
تعتبر هذه الدراسة مهمة للغاية لأنها تسلط الضوء على مشكلة صحية خطيرة تتعلق بتلوث أغذية الأطفال بالرصاص في سوريا. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل لو تم تضمين عينات من مناطق جغرافية مختلفة داخل سوريا للحصول على صورة أشمل عن مستويات التلوث. ثانياً، لم يتم التطرق بشكل كافٍ إلى تأثيرات الرصاص على الصحة العامة للأطفال، وكان من الممكن أن تكون الدراسة أكثر شمولاً إذا تم تضمين تحليل لتأثيرات الرصاص على الصحة. أخيراً، كان من المفيد تضمين توصيات واضحة ومحددة للحد من مستويات الرصاص في الأغذية.

Ninety-nine randomized samples of milk and white cheeses were collected
from five districts in Damascus city during 2012-2013 to determinef Aflatoxin
M1 using High Performance Liquid Chromatography (HPLC). The procedure
for determination of Aflato
xin M1 was changed according to local
circumnutates which gave sensitive and accurate results during 5.9 minute with
r= 0.99. The average recovery was 83.88% for milk and 102.15% for cheeses
samples, respectively.
the residual lead effect in cows milk was
studied in the Governant of Tartous. For this end,135 dairy cows in
different milking seasons and from three different farm stationes
(Zahed cow station,Cement factory farm station and Banias refinery
cow
station) were used.
The objective of the study was to accurately determine lead
concectrations in cows milk in the three different farms. Samples of
milk,soil,water and feedstuff were collected and lead concentration
was determined then statistically analyzed.
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..
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.
The importance of research being deals with the problem of
significant environmental concern the pollution of the plant , soil
and air component lead as a result of rapid industrial development
since the twentieth century . Was selected Eucalyptus
for several
considerations , including the widening spread and being one of
the bumpers wind that might ease the arrival of pollutants in the
atmosphere to regions far geographically . was selected several
sites of Homs in order to examine the content of the soil and
leaves Eucalyptus from a bullet was found that the concentration
of lead element in the plant was caused by air pollution , where not
shown the existence of relations clear engagement between the
content of soils of lead ( for a total and disposable absorption )
with the lead content of the plant . Ranged concentration of lead
overall in the soil between 1.98 ppm ( through Homs - peaceful )
and 72.47 ppm ( Highway Tartus in the south ) , and the average
of 4.857 ppm, did not exceed the concentration of lead in the
samples studied , both inside the city or outside the normal limit
and values lead stainless absorption in the soil ranged from ppm
(19.02- 0.02), ranged lead concentration in the plant between
2.01ppm and 10.35ppm and this concentration of lead element
within the permissible limits but with time become toxic showing a
lack of liaison relationships between the component lead either in
the soil or plant with the CaCO3 and Active lime. Finally we can
say that the contamination of the plant within the city is higher than elsewhere because of the busy traffic . Add to that the increase in soil lead content available led to increase the concentration of lead in Eucalyptus,leaves
