عين مستوى الرصاص في 52 عينة مخصصة لتغذية الأطفال متضمنة حليب الأبقار المجفـف و الأرز
و القمح و الحبوب و الفواكه فضلاً عن عينات من حليب الإنسان من الولادة و حتى عمر 12 شـهراً و ذلـك
باستخدام جهاز الامتصاص الذري-تقنية الفرن الغرافيتي-بعد تحضير العينات بواسطة التهضيم الرطـب

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.
