الحمأة في مخلفات حيوية صلبة Biosolids سوداء اللون تنتج عن محطات معالجة مياه الصرف الصحي وتستعمل في الزراعة لما تحتويه من مواد عضوية وعناصر معدنية مغذية تزيد من خصوبة التربة وتحسن من مواصفاتها
The study aimed to identify the environmental awareness among the kindergarten children
(high, middle, low) in Lattakia city. In order to achieve this objective, the sample of the
research of kindergarten children was selected from public and priva
te kindergartens. The
number of the sample reached (180) children of the age (5-6) years. This sample was
chosen stratified randomly. The researcher used the descriptive method to achieve the
objectives of the study.
The research tool consisted of a non-verbal environmental awareness scale, which was
developed by the researcher to suit the developmental characteristics of the kindergarten
child in The Syrian Environment. The study found that the level of the environmental
awareness of kindergarten children in Lattakia was high. The results also showed that there
were no differences between kindergarten children in their environmental awareness
according to gender and kindergarten's own.
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 ال
أخرى، 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.
The investigation aimed to survey the thistle of genus Carduus
spp in its habitat in Alswayda and Damascus countryside and
associated plants, by visiting these areas through flowering seasons
of Carduus spp during 2013- 2015.
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..
