Abstract :
SRXRF has been used to determine the multielement composition of the hair and blood of Tundra Nenetz children. The method allows one to simultaneously determine 21 elements in the blood and 22 elements in the hair. Individual differences have been revealed in the element composition of the hair and blood. Sexual and age changes have been revealed in the content of some elements in the hair. A technique has been developed to prepare blood and hair samples for measuring the element composition by the SRXRF method. The blood samples were prepared by spreading 20 μl over the 1 cm2 Whatman filter. The hair samples were obtained by pressing in the form of tablets of 1 cm in diameter and a mass of 10–40 mg.
