If an individual cannot be identified, it is necessary to conduct a forensic medical examination. In this case, all possible group indexes are investigated. In this study, the content of elements in hair was investigated to identify individuals by territory, age, profession, or gender. The level of 14 micro-and macroelements (Cu, Zn, Co, Fe, Cr, Mn, Cd, As, Pb, Ni, P, Ca, K and Mg) was determined in hair samples of men and women from five age categories (21 to >60) using inductively coupled plasma atomic emission spectroscopy. The samples were analyzed taking into account the health condition, gender, place of residence, occupation, work experience, and age. A correlation between the content of elements in peoples hair and their place of residence was observed. The difference in the content of elements in the hair of urban and rural residents was substantial and statistically significant (p<0.05). Moreover, there were significant differences related to age (p<0.0051) and gender (p<0.05). The current research detected significant differences in the content of the chemical elements in the hair of the groups tested, which can be used as personal identification indicators depending on occupation, work experience, and environmental factors.
