Abstract：Objective To determine the contents of 34 metal elements (Li, Be, B, Mg, Al, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Zr, Mo, Ag, Cd, Sn, Sb, Cs, Ba, Au, Hg, Tl, Pb, Th and U) in human blood from Guangdong Province, thus to provide evidence for evaluating the supplementary of trace elements. Methods A total of 315 blood samples from healthy population were collected for determination of 34 elements using in-ductively coupled plasma mass spectrometer (ICP -MS).The differences among 4 age groups were compared.Results The correlation coefficients were all good (r >0.999 2), the limits of detection ranged from 0.001 μg/L to 49.33 μg/L, the accuracies ranged from 90.78% to 111.17%, and the RSD ranged from 0.76% to 9.54%.The levels of Mg, Ca, Ti, Fe, Cu, Zn, Rb, Sr, Mo, Ag, Cd, Cs, Au and Hg were correlated to age.Conclusion Fourteen metal elements in human blood of Guangdong Province have significant differences among 4 different age groups.
