TLDR Copper levels differ by gender, and young children have higher mineral levels.
The study measured copper, zinc, iron, calcium, and magnesium levels in the hair of 1,800 children using a flame atomic absorption spectrometer. It found significant gender differences in copper levels but not in other elements. Children aged 0-3 months had higher levels of all elements compared to older age groups. Copper and zinc levels decreased from 3 to 12 months and slightly increased from 12 to 24 months, while iron, calcium, and magnesium levels gradually decreased but remained within normal ranges. The study suggested the importance of trace element supplementation for children.
