[Nickel and chromium content of selected human organs and body fluids]

Nickel and chromium analyses were performed in lung and kidney as well as in blood and urine samples of 45 autopsies from northern Bavaria area. The analyses were carried out with electrothermal atomic absorption after wet oxidative digestion. Median metal concentrations in blood were 4.5 micrograms Ni/kg resp. 2.8 micrograms Cr/kg, in urine 2.7 micrograms Ni/kg resp. 4.9 micrograms Cr/kg. The calculated values agree with the metal levels given in the new literature. Median metal concentrations in lung tissue were 7.4 micrograms Ni/kg resp. 36.5 micrograms Cr/kg; in the kidneys medians of 13.9 micrograms Ni/kg resp. 9.6 micrograms Cr/kg are found. In the literature only a few values for comparison are given. The metal concentrations in the different samples were not influenced by age or sex.
