v . .Memorandum' -cjn;an' Experimental Study of the Metabolism of Tetraethyl Lead in one Human Body (Kehoe, dov.

We have been unable to locate any literature relevant to this class of compounds other than the sort which you have contributed to regarding tetraethyl and tetramethyl lead.

We think it is quite feasible to make Fb203 using our accelerator 203 and to label lead tetraethyl with the Fb .

We estimate that the specific activity of the labeled lead tetraethyl will be sufficiently great to follow the lead using a conventional radiographic scanning technique as the lead is cleared from the lungs.

We think it is quite feasible to make Fb203 using our accelerator and to label lead tetraethyl with the Fb203 .

Keohe: e have several men in our operations who are exposed to mercury compounds and Tetraethyl Lead.

Keohe: e have several men in our operations "who are exposed to mercury compounds and Tetraethyl Lead.

I take the liberty of reminding you of my request for some bibliographical references or review article on the gen eral problem of lead tetraethyl toxicity.

Accordingly, the number of directors representing the tetraethyl industry was in creased to two for 1966-67, but this change was not regarded s precedent setting by this nominating committee.

Subject: Lead Warning Signs Dear Hank: I do not wish to be "difficult*' in the matter of the warning signs on pumps, but I do want to make the point quite clear that the authority for the wording on these signs is that of the tetraethyl lead industry.

D bhcli Developwnt Company ilKtryv'iile California bear Charlie: .it the request of representatives of both Shell and Ethyl in New York, I am sending herewith one copy of each of two reports that bear on the use of tetraaethyl lead as a substitute in whole or in part for tetraethyl load in gasoline.

Accordingly, the number of directors representing the tetraethyl industry was in creased to two for 1966-67, but this change was not regarded s precedent setting by this nominating committee.

It is known that . . . 2-naphthylamine and tetraethyl lead are converted to carcinogenic compounds."
