    TLDR Powdered milk in Senegal has varying heavy metal levels, with some exceeding safety limits, needing more regulation.
    This study analyzed heavy metal concentrations in five powdered milk samples from Senegal using X-ray Fluorescence (XRF). Aluminum was undetected or negligible, while calcium levels exceeded the Acceptable Maximum Level (AML) in all samples, with H1 surpassing it by 11.1 times. Potassium levels varied, with G1 significantly exceeding the AML, whereas V1 was within limits. Chlorine levels were mostly compliant, except for G1, which slightly exceeded the AML. Phosphorus in H1 was notably higher than the AML. The variability in heavy metal concentrations highlights the need for further research and regulatory measures to ensure powdered milk safety.
