Title Accumulated body burden and endogenous release of lead in employees of a lead smelter
Bibliographic information Feb. 1997, Vol.105, No.2, p.224-233. Illus. 31 ref.
Abstract Bone lead levels were measured by X-ray fluorescence in a population of 367 active and 14 retired lead smelter workers. Whole-blood lead readings from the workers generated a cumulative blood lead index (CBLI) that approximated the level of lead exposure over time. Relations between bone lead concentration and CBLI demonstrated a distinctly nonlinear appearance. When the active population was divided according to date of hire, a significant difference in the bone lead-CBLI slope emerged. The transfer of lead from blood to bone in the workers has apparently changed over time, possibly as a consequence of different exposure conditions.
