درسنا تأثير التلوث البيئي في مستوى الرصاص في حليب الثدي عند خمس مجموعات من الأمهات المرضعات في عدة مناطق من جنوب سوريا، مصنفة بيئيًا و هي: المجموعة الأولى: من مناطق الريف البعيد (ريف السويداء و القنيطرة) عن الطرق العامة و المصانع و مصادر التلوث الأخرى، و تقل كثيرًا الآليات فيها (مجموعة المراقبة). المجموعة الثانية: مدينة صغيرة (السويداء) قليلة الازدحام، خالية من المصانع. المجموعة الثالثة: مدينة كبيرة (دمشق) كثيرة الازدحام، تتعرض لهواء ملوث من الآليات و الصناعات. المجموعة الرابعة: ضواحٍ صناعية (جنوب دمشق) مزدحمة بالآليات المختلفة. المجموعة الخامسة: ضواحٍ صناعية (شرق دمشق) مزدحمة جدًا بالآليات، و تتعرض كثيرًا للهواء الملوث.

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 w
ere 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.
A study of chemical composition of woman's milk has been
made and compared with cow's milk in the province of Homs.
The findings of this study show that The total value of the solid
material in cow's milk is (12.26 ± 1.2%). It is approximately
eq
ual to woman 's milk content of the total solid material which
is (12.11 ± 0.09%).
The woman 's milk content of mineral elements is (02% ±
001%), while the cow's milk content is (0.71 ± 0.14%).
For the value of fatty material in the mother's milk, it is (3.5 ±
0.02%) and this is almost equal to cow's milk content of the
same material which is (3.4 ± 0.05%).
The cow's milk content of protein is equivalent to (2.92 ±
0.019%), whereas cow's milk content is equivalent to ( 1.25 ±
0.009%).
The value of calcium in the mother's milk is (32 ± 4.3 mg), and
this is significantly lower than the value of the calcium in cow's
milk, which is (118 ± 8.2 Mg/ kg).
يهدف البحث إل رصد مستويات الرصاص في نوعين من النباتات في منطقة دمشق حيث يعتبر النبات مشعراً حيوياً للتلوث بالرصاص
The research paper is focussed on an important topic for architects and
urban planners dealing with sustainable urban environment and
architecture.
The focus of the research is laid on comparative studies of two German
examples: The Federal Institution of Environment „Umweltbundesamt“ in
Dessau and the Eco-Settlement (Kronsberg) in Hannover.
- The objective of this study was to assess the level of air
contamination by bacteria in the broiler houses in salamieh region
that Famed of commercial breedings of broiler and relationship
with some impact factors like (birds age- season-breedin
g system -
dust concentration) .
- The numbers of bacteria (mesophile , staphylococci , streptococci
and gram-negatives) and dust concentration were determined in 5
opened broiler houses and 5 closed broiler houses with chicken
houses in different ages (1-6 weeks old) in summer and winter .
