As to the article by Duvolr and Coste, I wonder if it would not be advisable to have instructions issued to our various medical consultants abroad that all articles on tetraethyl lead and leaded gasoline be submitted to you and by you to Edgar as Director of Research in order to make sure that no significant technical errors get into . the literature.by way of our own people, I shall raise this question with Edgar in New York tomorrow, and I dare say you will hear from him on the subject.

Booth indicated that the case would never come to trial, and was related to tetraethyl lead only indirectly, as Mr.

We have nothing to cover up, and if v;e should find evidence of significant exposure to tetraethyl lead under any cf the conditions which we now believe to be free of hazard, we shall have to investigate further until the facts can be made clear.

.- ETHYLPORT- BUENOS AIRES Buenos Aires,May 22nd,1945 Dr<>Robert A,,Kehoe, Kettering Laboratory of Applied Physiology, University of Cincinnati, Cincinnati - Ohio - USA,-* Dear Dr,,Kehoe, I am very much obliged to you for your letter of April 28th, 1945 enclosing a very comprehensive memorandum on the hygienic requirements for the manufacture and transportation of lead tetraethyl and its highly concentrated mixtures,and for mixing 3uch materials with gasoline.

In addition, you should avoid contact with gasoline with great care reg&ruless of whether or not it is gasoline containing lead.

Most human exposure to lead, on the other hand, is to lead oxides or lead fumes which are inhaled.

Th ere is also the hazard o f later exposure to either interm ediate or end products o f the reactions of decontaminants on tetraethyl lead ( T .E .L .)

Or blatant advertising of a new lead compound might create a,competitive situation that would result in reprisals to the discredit of tetramethyl lead, or even tetraethyl lead.

This is equally true of the two articles on "An Appraisal of the Load Hazards Associated with the Distribution and Use of Gasoline Containing Tetraethyl Lead.

Tetraethyl lead poisoning clinical.

First, we need to know whether there are any conditions under which unchanged tetraethyl lead can escape in the exhaust gas.

Scales and certain of his associates in the Research Laboratories of Ethyl Corporation in Detroit, in an effort to supply technical information pertinent to the nature and extent of the potential hazard involved in the substitution of tetramethyl lead for tetraethyl lead in antiknock fluids.

This is equally true of the two articles on "An Appraisal of the Load Hazards Associated with the Distribution and Use of Gasoline Containing Tetraethyl Lead.

Kehoe: Your manuscript, Part T, on tetraethyl lead, has been read by a number of our editors.
