EXPSUSSNTAL STUDIES car TETRAETHYL LEAD P0I 3CETI B3 BT ROBERT A.

'be about three times as toxic as tetraethyl lead* This is probably due to the greater ease of absorption of lead salts in the alimentary tract* On the other hand* lead salts are not absorbed in lethal doses from shin* whereas death may readily he produced by the application of tetraethyl lead to the shin.

these being relatively soluble in water as contrasted with tetraethyl lead, and being crystalline solIda rather than the oily liquid which is tetraethyl lead.

On the assumption that you will probably receive some small mippXy of tetraethyl lead, I wish to point out the quit considerable danger of handling even small amounts of tetraethyl lead.

Gorman knew of the possibility of tetraethyl lead intoxication.

Jims 7 15S39 Captain E, L Bergquist Station Hosptialj, Air Corps Advanced Plying 'cliool, Kelly field, Texas* Dear Captain Bergquistj I have your letter of June 3rd mid will endeavor `to answer your questions to the best of z t j ability, 1 ETHYL FLUID contains tetraethyl lead and aa organic iialxd (in the avaition fluid tit halid is thyXensdibroisi&* and the propcsrtion of tetraethyl lead to othylss0 -*ait.roaid is that theoretically required for complete Gosbinatlom to fora lead bromid)* in the ocaabustiaa* it is boliaved that the tetraethyl lead turns to lead oxide and the halids to acid* these tssr then combining to form lead halid*, This material is largely volatil-. ized opt of the cylinder itssif and is partially deposited in the exhaust system and partially 'blows ant with the exhaust gases - 2 There is no evident?

iodine required times 0.01617 equals the weight of tetraethyl lead in the sample.

The risk of oral absorption of tetraethyl lead is negligible, and the ingestion of gasoline containing tetraethyl lead is of no practical importance in relation to the lead compound, since one could not ingest enough lead by this means to produce illness without taking many times the lethal dose of gasoline. .

At the end of the reaction the product is separated from the reaction mixture and is entirely free from tetraethyl lead.

Uo attempt to recover tetraethyl lead from the process is contemplated.

% lead - 3.44# Pb. calculated as lead tetraethyl - 538.00.. mgs % lead tetraethyl - 5.38 % C.

P. salt, in which case 1 ce. of this solution used on an original 10 0 -cc, sample of gasoline corresponds to 0 * 1 cc* of tetraethyl lead (sp.gr. 1.65) per gallon of gasoline.

,pounds* For your further information alien me . . to refer you to a description of characteristic tetraethyl lead intoxication as described by rsy associate Dr* W.
