Detection and Survey of Heavy Metals Residues in Infant Formulas and Condensed Milk [electronic resource].

Includes references.

A total of 60 samples of infant formulas include (ready to use and powdered milk based formulas), infant milk and condensed milk (15 samples each), were collected randomly from Zagazig City supermarkets and pharmacies. The collected samples were analyzed for detection of aluminum, tin, copper and manganese using Atomic Absorption Spectrophotometer. The average of aluminum in ready to use milk based formulas, powdered milk based formulas, infant milk and condensed milk were 2.87 ± 0.08, 1.5±0.02, 2.16±0.16 and 0.11±0.01 (ppm) respectively. On the other hand, the mean values of tin in ready to use milk based formulas, powdered milk based formulas, infant milk and condensed milk were 0.89±0.30, 0.42±0.10, 1.8±O.I6 and 134±0.41 (ppm) respectively. Meanwhile, the average of copper in ready to use milk based formulas, powdered milk. based formulas, infant milk and condensed milk were 0.58±0.23, 2.90±0.75, 0.72±0.02 and 0.19±0.02 (ppm) respectively. Manganese levels in all examined samples were high in comparison with the permissible limits. The public health hazard and sources of contamination by heavy metals (AL and Sn), and the changes in essential elements (Cu and Mn) were discussed.
