Hair copper concentration in healthy children,teenagers, and adults living in Szczecin,Poland

The aim of this study was to assess the hair copper concentration in a population of healthy children, teenagers, and adults living in a specific region of Poland. For this purpose, 840 healthy individuals aged 1–50 yr living in Szczecin, Poland were selected for the study. They were divided into subgroups according to age and sex and the hair was analyzed for copper using a standard atomic absorption spectrometric technique. The level of copper was highest for the group including 11–15 yr old. In the other subgroups, the concentration of copper was lower than the values considered normal, suggesting the possibility of endemic copper deficiency in the inhabitants of this region.
