Correlations between some elements in hair of healthy controls, mentally handicapped, psychiatric patients and somatic patients determined using atomic absorption spectrometry
The study of content of K, Mg, Ca, Na, Zn, Cu, Fe, Li, and Pb in human hair was carried out on 300 individuals in the years 1996-2002. The patients were from Lublin, Zamość, Łabunie, Krasnystaw, Ostrów Krupski, and Zwierzyniec. The samples of hair to be examined for the content of Mg, K, Na, Zn, Cu, Fe, Li, and Pb were collected from 79 healthy controls, 98 mentally handicapped, 81 psychiatric patients and 42 somatic patients. The content of particular elements in hair was determined using atomic absorption spectometer type AAS-3 (Carl Zeiss), attached to a microcomputer type 113 MPC/38 C and Spectr AA 880 by Varian. The results of the study of hair revealed the positive correlation between Mg and Pb (Rs=0,49, p=0,000024) and between K and Na in healthy controls. Negative correlation was revealed between Mg and K in healthy controls and between Mg and Ca in all studied patients.
