هدفت هذه الدراسة إلى تحديد مستويات الرصاص و الكادميوم في لحوم و كلى و أكباد الخراف المعروضة في الأسواق المحلية لمدينة اللاذقية, و مقارنة النتائج مع ما هو منشور في البلاد الأخرى, و مع الحدود القصوى المسموح بها للاستهلاك البشري, و قد تم التحليل باستخدام مطياف الامتصاص الذري ( AAS ). بلغ متوسط تركيز الرصاص في اللحم و الكلى و أكباد الأغنام 0.043 , 0.284 , 0.118 ملغ/كلغ من الوزن الرطب, على التوالي, و بلغ متوسط تركيز الكادميوم 0.017 , 0.173 , 0.252 ملغ/كلغ من الوزن الرطب, على التوالي, و قد بين التحليل الإحصائي وجود فروق معنوية في تركيز الرصاص و الكادميوم بين كل من الأكباد و الكلى و اللحم.
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.

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.
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 present study aimed to investigate the capacity of biotin in preventing
oxidative stress induced by hydrogen peroxide H2O2 at a concentration of 1%
given with consumed drinking water to local male rabbits. 40 male rabbits aged
7-8 months, were
used in this study and were divided randomly into four
groups, with 10 rabbits within group, as follow: the first group was given
standard forage and normal water and considered as control, the second group
was given standard forage and 1% H2O2 in water, the third group was given
standard forage and 200 mg biotin /kg body weight in water, the fourth group
was given standard forage, 1% H2O2 and 200 mg biotin /kg body weight in
water. All groups were treated daily for 8 weeks.
The concentrations of copper (Cu) and zinc (Zn) in samples of some cereals available at
local markets in Syria weredetermined, after nitric digestion, using Atomic Absorption
Spectrometry. The study showed that the heavy metals were present in all
samples at different
levels. The concentration of heavy metals varied from trace to higher concentration.
The maximum level of copper (Cu) in the cereal samples was 0.426 mg kg-1 on dry
weight basis, where the maximum level of zinc (Zn) in the cereal samples was 2.325mg mg kg-
1 on dry weight basis. 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
concentration recommended by the World Health Organization.
