تم تحديد تركيز الرصاص و الكادميوم في عدد من المنتجات الزراعية المحمية و غير المحمية (بندورة، و فليفلة، و ملفوف، و بقدونس) بهدف مقارنة قدرتها على تجميع هذين العنصرين، و ذلك بسبب كون هذه المزروعات متأثرة بالأنشطة البشرية و الصناعية. بعد جمع العينات تم تهضيمها بوساطة حمض الآزوت، و من ثم الكشف عن الرصاص و الكادميوم باستخدام تقنية الامتصاص الذري. أظهرت النتائج أن تراكيز هذين العنصرين في العينات المتأتية من الزراعات المحمية أقل من تلك المتأتية من الزراعات غير المحمية كون تلك الأخيرة معرضة مباشرة لتلوث الهواء الجوي، مما يزيد من إمكانية تراكمها في تلك المزروعات، كما أظهرت النتائج أن تركيز الرصاص في العينات كافة أعلى من تركيز الكادميوم، و هي ضمن الحدود الطبيعية في نوع كهذا من المنتجات الزراعية.
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.

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.
