The median concentration of W in blood was < 0.2 mug/l (below the detection limit) and in serum 0.087 mug/l. The median concentrations of Cd, Rh, Pd, Pt and TI were below the detection limits. Statistically significant correlations were found between the concentrations in blood and serum for Co, Cu, Zn, Se, Rb, W, Hg and Pb. The levels presented in this study constitute baseline levels or levels generally not exceeded in adolescents for 13 elements, including essential, ubiquitous toxic, and rare elements.
