Dairy products samples were contaminated with variable amounts of heavy metals. Drinking water used to mix infant powdered formula may add cadmium and lead significantly to the concentrations in the ready-made products. The presence of heavy metals in human's diet even in low level, can lead to presence of these metals in human's body by considerable concentration. Metals that cannot be metabolized (as cadmium and lead), persisted in the body and exerted their toxic effectby combining with one or more reactive group essential for normalphysiological function and cellular disturbance or clinical manifestations may be appeared. Hence, seventy random samples of some dried milk products (infant powdered milk based formulae) were collected from different markets and pharmacies in Assiut Governorate, Egypt. These samples were collected in their original containers and packets, and transported to the laboratory for estimation of lead (pb), cadmium (cd) and selenium (se) levels. The digest, blanks and standard solutions were aspirated by Atomic Absorption Spectrophotometer (VARIAN, model AA240 FS, Australia). The percentage of positive samples for lead, cadmium and selenium was 60, 51.4 and 100%, respectively, in the first type and 48.6, 40 and 100%, respectively, in the second type. The results of positive samples that exceeded the MPL for lead, cadmium and selenium showed in the first type 76.2, 72.2 and 17.1%, respectively, and in the second type 82.4, 57.1 and 2.9%, respectively. The values ​​of the quantities measured weekly (EWI) for lead, cadmium and selenium were in the first type according to the averages 7.546, 4.312 and 0.973 mg / kg of body weight, respectively, while the second type was 3.675, 1.652 and 0.553 mg / kg of body weight.
