Interrelationship Between the Concentration of Heavy Metals in Normal Korean Tissues

Concentrations of heavy metals, including As, Cd, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Se, Si, Sn, V and Zn in the internal organs (liver, kidney, heart, lung, spleen, cerebrum and bone) of Korean obtained from 91 forensic medical autopsy cadavers, with an age range of 12-87 years, were determined by inductively coupled plasma atomic emission spectrometry. From the results, positive correlation with age was observed in the following cases : Cd in liver, kidney and cerebrum ; Fe in cerebrum and bone ; Pb in bone ; V in lung. Copper in heart, Hg in bone and Mn in kidney correlated negatively with age. A signigicantly positive correlation between Se and Hg was only observed in heart. Significant correlation coefficients between Se and As were observed in liver, kidney, heart, spleen and bone. The correlation between Cd and Zn was signigicant in liver and kidney, indicating that the distribution of Cd is similar to that of Zn in the liver and kidney.
