Contents of bioelements and toxic metals in the Polish population determined by hair analysis. Part IV. Adults aged 40 to 60 years.
The aim of this study was to define referential values of 5 basic bioelements (Ca, Mg, Zn, Cu, Fe) and 2 toxic metals (Pb and Cd) in the hair of Polish adults aged 40 to 60 years, based on the research conducted from 1991 to 2006 on a group of 3349 formally healthy women and men. The results of our biochemical tests were subjected to statistical analysis and they can be treated as referential norms for the concentrations of analyzed bioelements in the hair of Polish population. Our analyses confirm significant differences in accumulations of certain elements (Ca, Mg, Zn) in women's and men's hair. The hair element analysis of the tested women population indicates the age 49-50 as the one in which a significant decrease of hair Ca and Zn begins. Marked decrease of Ca and Zn in men begins 2-3 years later than in women. A slight tendency to decrease hair Mg in women and men during the period observed of 40-60 years of age was noticed. Significant differences (alpha = 0.05) between hair Cu contents in women and men were not observed. The increase of variances of hair Fe concentrations in women, especially after 50, has been observed. Significantly higher hair Pb and Cd concentrations were shown in men. The analysis of correlation confirms the significance (p < 0.050000) of synergistic interactions between bioelements: Ca-Mg (r = +0.7635), Ca-Zn (r = +0.36), Ca-Cu (r = +0.124), Ca-Fe (r = +0.054), Mg-Zn (r = +0.35), Mg-Cu (r = +0.11), Mg-Fe (r = +0.0757), Zn-Cu (r = +0.11), Cu-Fe (r = +0.0765). Significance (p < 0.050000) of antagonistic interactions of bioelements with toxic metals: Ca-Pb (r = -0.0965), Zn-Pb (r = -0.2476), Mg-Pb (r = -0.13), Zn-Cd (r = -0.0889) was established. Significance (p < 0.050000) of synergistic effects with toxic metals: Pb-Cd (r = +0.3322), Cu-Pb (r = +0.09), Fe-Pb (r = +0.1413), Fe-Cd (r = +0.1161) was confirmed. Adults in whose hair bioelements and hair toxic metal concentrations have shown values outlying from reference and who have too much toxic elements and too little bioelements should undergo further diagnostic tests since these results could be a sign of disturbances, that could lead to various diseases.
