Abstract

Zn concentrations in the hair of children from 6 to 17 have been studied in two ethnic groups (Chuvashs and Bashkirs). The distribution analysis of the levels of this element showed an absence of its deficit in the groups studied. Correlation analysis revealed statistically significant connections (p<0.05) between Zn contents and certain morphological traits. They reach their maximum in boys at the end of the pubertal period. Obtained correlation coefficients are average in their values and negative by their sign. Significant differences in correlation values and signs between Chuvash and Bashkir children were not discovered. The study shows that there is an influence of Zn concentrations on growth and development tempos of morphological traits in children, which needs to be taken into consideration when the results of anthropoecological investigations are interpreted.
