  • Title: Distribution of nickel, zinc, and copper in rat organs after oral administration of nickel(II) chloride.
    Author: Cempel M, Janicka K.
    Journal: Biol Trace Elem Res; 2002; 90(1-3):215-26. PubMed ID: 12666836.
    Abstract:
    The distribution of Ni administered as NiCl2 x 6H2O in the drinking water (300 and 1200 ppm Ni for 90 d) was studied using male Wistar rats. Next, the effect of Ni on the concentration of zinc (Zn) and copper (Cu) in selected organs and serum was measured. The metals were analyzed in the liver, kidney, lung, spleen, brain, and serum by electrothermal (Ni) or flame (Zn, Cu) atomic absorption spectrophotometry. The results indicate that exposed rats drank less nickel solutions than the volume of water drunk by controls, but there was no mortality of animals. In comparison to control animals, a very high increase in Ni levels was found in the kidney and then lung and serum of all exposed rats. In the liver, spleen, and brain, the metal accumulation was lower. A directly proportional relation between the nickel intake and its deposition was observed in the collected organs and in the serum. The metal level did not change significantly in the course of exposure (the first analysis was after 30 d). The administration of 300 ppm Ni did not affect the zinc and copper concentration in studied organs, except the serum, where zinc content was significantly reduced. At a dose of 1200 ppm Ni, these metals were found to be depressed in the liver, kidney, serum (zinc), and copper in the kidney.
