Objective: Hair analysis may be used both in the assessment of element deficiencies in humans as well as environmental and occupational exposure to heavy metals. Materials and methods: This paper evaluates the correlation of a test subject's age to the content of elements such as calcium (Ca), magnesium (Mg), zinc (Zn), copper (Cu), iron (Fe), lead (Pb), and cadmium (Cd) in human hair. The content of elements was determined in the hair of 1,038 females and males for five age groups. Quantitative measurements have been performed using atomic absorption spectrometry (AAS). The results were processed using statistical analysis methods including Principal Components Analysis (PCA). Results: The overall mean concentrations of elements in hair were as follows (mu g/g): Ca - 431, Mg - 19, Zn - 161, Cu - 13, Fe - 10, Pb - 0,8, Cd - 0,06. The most frequently correlated elemental pairs are: Ca and Mg, Ca and Zn, Mg and Zn, as well as Pb and Cd. In some cases correlations were found for Fe-Pb and Fe-Cd. The content of investigated elements in hair both for females and males differs in the selected age groups. However, for Cd and Cu the differences are not.very significant. The smallest amounts of Ca, Mg, and Zn, but the larger contents of toxic metals in hair were observed for children, elderly people and males in comparison to adults and females. Conclusions: Taking into account the high variability of results, further research on the content of elements in human hair should be continued, especially in the case of children.
