Elemental status of students of different social groups
The study of some features of the ultimate hair composition of youth-students of different social groups was been carried out (students from couple families and orphan students). Evaluation of the ultimate hair composition was carried out by inductive coupled plasma-atomic emission spectroscopy. The samples analysis was carried out at 25 chemical elements. Excessive content of iron and lithium and also cobalt and selenium deficiency were revealed in all students compared with the average Russian parameters. Excessive content of magnesium and zinc were peculiar to orphan-students. Some differences between the groups for both the individual elements and elements ratios have been found. The sodium (1.7 times;p=0,006), potassium (3.2 times;p=0,019) and aluminum (1.4 times;p=0,006) content were significantly higher in the hair of couple-family students but the content of selenium (p=0,050) was lower. As a result of higher potassium content in this group, content of Ca/K and Na/K (5.4 and 1.4 times respectively) was significantly lower. The correlation analysis showed a close relationship between the content of calcium and magnesium, as well as iron and manganese in hair of students of both groups. The study results can be applied in the development of modern non-invasive diagnostic techniques.
