Gonzalez, concerning the handling of small shipments of tetraethyl lead from the Detroit Laboratory.

They seem to be in no way concerned with the toxic properties of tetraethyl lead, and also seam to feel that their experience in handling this typo o?

Over all the problem does not differ substantially from that presented by Tetraethyl ^ead and it is intended to apply the same safety recommendations in respect of manufacture and distribution as applied to Tetraethyl Lead at the present time.

Dear Doctor Stovall: Yo u r letter of Februari* 19, requesting an opinion a s to the advisability of increasing the tetraethyl lead content of aviation gasoline fro m 3.0 cc. to 4.6 cc. for commercial aircraft, has been viven consideration. .

From the best information which is available to me I would feel that the hazard of the handling of your present "Vitol " mixture, from the aspect of evaporation of tetraethyl lead, would be approximately equivalent to that of handling gasoline containing 350 c.c. tetraethyl lead per gallon.

Over all the problem does not differ substantially from that presented by Tetraethyl 1-,ead and it is intended to apply the same safety recommendations in respect of manufacture and distribution as applied to Tetraethyl Lead at the present time.

They seam to bo in no way concerned with the toxic properties of tetraethyl lead, and also seem to feel that their experience in handling this typo of^ ^ a ^ ualifles them competely.

The concentrations employed by the Army are not in excess of k cc of tetraethyl lead per American gallon.

I did not say, and in fact, did not discuss,In this relationship, the practical Industrial hazards of tetraethyl lead.

With respect to your having a sample of tetraethyl lead, I think something can be done to satisfy you.

The rathor gross discrepancy between the concentrations in the blood and urine is characteristic to some degree of the behavior of tetraethyl lead.

They have further informed me that certain suppliers of antiknock compound propose to manufacture and sell compounds containing tetramethyl lead and that certain refiners would like to use them because their use provides certain technical and economic advantages over compounds containing tetraethyl lead.

The rather gross discrepancy between the concentrations in the blood and urine is characteristic to some degree of the behavior of tetraethyl lead.
