Kitzmiller Dear Doctor Kitzmiller: I greatly appreciate your letter of November 17, 1953 which arrived in time for the meeting of our Smog Committee on November 19* I was very much i:nterested in reading the relative lead concentrations in the group o.f individuals who have worked at the Ethyl Terminal In Wilmington and especially the fact that they had worked there for over five years One of the real concerns of our Committee Is this: We have been told that betwee n 10 and 12 tons of lead are emitted daily in this area through the burning of tetraethyl in our fuels.

I have just received a letter from Join in which he states that the present tetraethyl lead by gravimetric analysis ran as high as 25^ {Z2% fluid).

He offers to make available any information that the Ethyl Corporation has that would be useful to me in connection with the Surgeon General's Committee that has been appointed to consider possible increase in the permissive amounts of lead tetraethyl in gasoline.

Because of the prominence he has given to the aspects of tetraethyl lead, we are being pressed repeatedly by major customers on the West Coast to render an.opinion or take some action.

I have just received a letter from John in which he states that the present tetraethyl lead by gravimetric analysis ran as high as 2B% (Zd% fluid).

, e, absorption - of lead cannot possibly occur without elevation of the lead concentration in the blood except when the material absorbed is tetraethyl lead; the equilibrium with the blood is as inevitable as is the presence of inorganic lead in the body (you hardly need worry about tetraethyl lead, since this type of poisoning is almost never seen by physicians generally); 001249b Dr.

Some of the essential differences between this form of encephalopathy and that due to tetraethyl lead are outlined.

Perhaps, one of the most dramatic cases of the effect of additives is the well known exnmple of tetraethyl lead.

At the same time this is done, arrangements can be made to have lead analyses made in connection with your work.

The items considered were, with the exception of the last, the same as mentioned to each of you and were as follows: On page 1 about half way down, a statement will be made that the total lead*liberated to the atmosphere will be the same with X-105A as with tetraethyl lead when gasolines are "doped" to the same lead level.

This was presented in part, such as, for example, the data and discussion and tetraethyl lead poisoning as a general industrial and hygienic problem,and the observations made on the metabolism of lead that prove "deleading," by the most commonly suggested means, to be an impossibility.
