Dear Sir: The question of medical control of lead workers has arisen again and we would appreciate your opinion concerning the safe . limits of lead absorption, as determined by urinary lead, blood lead, basophilic stippling, or coproporphyrin excretion, for routine movement of workmen from a lead hazard area. 1 We would also appreciate an outline of a medical program suitable for lead workers. We are particularly interested in the frequency of examination, allowable limits of absorptions and rota tion period of workmen from a lead hazard area to a non-hazard area. Yours very truly, WORKMEN'S COMPENSATION BOARD. R'. F.-Fulton, Industrial Hygiene Department.. \b 0015673
