    Area of Science:

    • Environmental Science
    • Human Health
    • Analytical Chemistry

    Background:

    • Human milk composition is crucial for infant nutrition.
    • Trace elements play vital roles in infant development and health.
    • Regional variations in human milk trace element content are not well-documented.

    Purpose of the Study:

    • To quantify the concentrations of 12 trace elements in human milk samples.
    • To establish baseline data for specific trace elements in colostrum and transitional milk from the Ljubljana region.
    • To compare findings with existing literature values.

    Main Methods:

    • Radiochemical neutron activation analysis (RNAA) was employed for trace element quantification.
    • Samples of human milk, primarily colostrum and transitional milk, were collected.

    Related Experiment Videos

  • The analysis covered Arsenic (As), Cadmium (Cd), Cobalt (Co), Copper (Cu), Mercury (Hg), Iodine (I), Manganese (Mn), Antimony (Sb), Selenium (Se), Tin (Sn), Vanadium (V), and Zinc (Zn).

    • Main Results:

    • Concentrations of 12 trace elements were determined in human milk samples.
    • Data were collected for colostrum and transitional milk from the Ljubljana area.
    • Reported values provide a regional profile of trace element content.

    Conclusions:

    • The study provides valuable data on trace element levels in human milk from a specific region.
    • These findings can contribute to understanding nutritional status and potential environmental exposures.
    • Further research may explore the implications of these levels for infant health.
