We have never had a case of tetraethyl lead intoxication among the mixing personnel in this country* Indeed, several systematic investigations of the' mixing personnel .made some what at random, have demonstrated that the absorption of tetraethyl lead among these men is negligible.

If I am mistaken in this assumption, I should like to know, sines, as you may be aware, we have undertaken to keep a very close watch on all situations that lead to hazard in the handling of-tetraethyl lead or leaded gasoline.

August 4, 1936 Dr# M* Townsend DeHott* 645 South Third Street Jhillipaburg Kansas Dear Dr# DeMottei X have your letter f August let and an referring it to our Medical Department with the request that they give you full information on the subject# Meanwhile* although 1 m net a physioian thyself* Z oan express an opinion that it is Impossible for lead poisoning to have teen acquired by breathing fumes of gasoline containing tetraethyl lead sine the vapor pressure of tetraethyl lead is so low that only a negligible quantity is present in the fumes above a bucket of the gasoline.

b/gal. added as 70-45 Lthyl fluid) in a 55 gallon vented* half-filled steel drum produced a decomposition of 3.1; of the original tetraethyl lead with 74,5 of the decomposed tetraethyl lead soluole in the gasoline arid the remaining 2(5;- present in the sludge. 0 . f/ y 25 gas.

The introduction of tetraethyl lead into the human body will cause lead poisoning, which does not differ from the poisoning of any other form of lead from the standpoint of cause and effect, but is undoubtedly brought about more rapidly.

The only lead compounds that are absorbed to an important degree through the skin, so far as m y knowledge and experience goes, are the liquid alkyl lead compounds, of which the only one in commercial use is tetraethyl lead.

You will also recall that some data are in the British Health Report on the absence of tetraethyl lead and the amounts of inorganic lead in lubricating oil* X doubt if we have any data on the use of engines in mines* but I have asked the laboratory to look into the matter* With kindest personal regards, believe me Very tnrly'yours, g e /l r j Graham Edgar

We have had experience with all phases of this problem with respect"/ v to safety, and have responsibility In dealing with the safe handlings of tetraethyl lead fluid, and it may be that we can offer some / helpful advice.
