Comparative characteristics of the elemental composition of teenagers' biosamples depending on living conditions of the Khabarovsky Kray

Abstract

Introduction. The elemental status of an organism reflects the geochemical background of the habitat, including the imbalance of trace elements in the water and soil of a given region. We presented the results of studying the concentration of Fe, Сu, Mo, Zn, Co, Se, Th and U in the hair of teenagers with different living conditions of the Khabarovsky Kray. Aim. To analyze the level of influence of the elemental composition of drinking water and soil on the ecological portrait of teenagers living in different regions of the Khabarovsky Kray. Materials and methods. The analysis of trace elements in hair, soil and drinking water was carried out by means of inductively coupled plasma atomic emission spectroscopy. Results. Significant correlations were found between the concentration of Fe, Co, Mo, Th in hair and water (r=0.48-0.89), Fe, Cu, Zn, Se in hair and soil (r=0.38-0.71). The value of correlation relationships among children of Khabarovsk and the Nikolaevsky district is 1.5 times higher than among teenagers of the Okhotsky district. Conclusion. Thus, an imbalance of trace elements in the environment can affect health and be a risk factor for the development of environmentally related diseases.
