This study assessed the concentrations of heavy metals and micronutrients in Milo and selected sachet milk
brands consumed in Gombe Metropolis, Nigeria, using X-ray Fluorescence (XRF) spectrometry. The objective
was to evaluate both the nutritional quality and potential health risks associated with these widely consumed
beverages. Four samples comprising three milk brands and one Milo sample were collected from Gombe Main
Market and analyzed for elemental composition. The results revealed the presence of essential micronutrients
such as calcium, potassium, phosphorus, iron, zinc, and copper at significantly elevated concentrations.
Notably, calcium (281,500–320,140 ppm) and potassium (193,440–220,000 ppm) were found in extremely high
amounts, suggesting possible fortification or concentration beyond standard dietary levels. Iron concentration
was exceptionally high in the Milo sample (13,079 ppm), indicating heavy fortification. Conversely, toxic heavy
metals such as arsenic (As), lead (Pb), nickel (Ni), and chromium (Cr) were not detected in any of the samples,
indicating minimal contamination from these hazardous elements. However, the concentrations of some trace
elements, particularly copper and zinc, exceeded permissible limits recommended by international standards
(WHO/FAO), raising concerns about potential health risks associated with excessive intake. The findings
suggest that while the products are rich in essential nutrients, their unusually high elemental concentrations
may pose risks of mineral toxicity if consumed regularly. In conclusion, Milo and sachet milk sold in Gombe are
significant sources of micronutrients but require continuous monitoring and regulatory control to ensure
consumer safety
