title: X-ray fluorescence in the assessment of inter-elemental interactions in rat liver following lead treatment.
abstract: Energy dispersive X-ray fluorescence technique was employed to study the interactions of lead (50 and 100 mg/kg body wt) with K, Fe, Cu, Zn, Br and Rb in rat liver. Lead was administered orally to rats daily for dosage periods of 1 and 4 months (short and long terms). Hepatic Fe levels were found to increase significantly with the supplementation of low and high doses of lead for both the treatment periods, although the increase was more pronounced following long-term treatment. The levels of hepatic K, Cu and Br were seen to decrease significantly over both time intervals. Moreover, hepatic Rb contents were lowered with the short-term supplementation of low doses of lead. In contrast, Rb and Zn levels were increased when lead was administered for the longer period at both dose levels.
