ACCUMULATION OF CHROMIUM IN HYBRO CHICKENS LIVER TREATED WITH Cr(VI) AND VITAMIN C

In this study the role of vitamin C in the accumulation of chromium in the liver and liver lesions of Hybro chicken treated with Cr(VI) were investigated. The chickens were divided into 5 groups (I-V), with 10 individuals which and were treated orally with different concentrations of chromium (Gr. II - 0 ?g CrO3/kg b.w; Gr. II - 25 ?g CrO3/kg b.w; Gr. III - 50 ?g CrO3/kg b.w; Gr. IV - 25 ?g CrO3 + 10 mg vit. C/kg b.w; Gr. V - 50 ?g CrO3 + 10 mg vit. C/kg b.w). The Cr concentration in the liver was determined by atomic absorption spectroscopy (AAS) via Perkin Elmer 600AA type spectrometer. Vitamin C combined with Cr(VI) doses amplifies the bioaccumulation of Cr in the liver to a considerable degree, compared not only with control group of chickens but as well as with the chickens treated only with Cr(VI). The results of this investigation show that the bioaccumulation of chromium in the liver depend on the dose, time of action and the combination of Cr with Vitamin C.
