Most o f the foregoing material, was obtained fxaom the following sources: "An Appraisal of the Lead Hazard Associated with the Distribution and Use of Gasoline Containing Tetraethyl Lead."

As a matter of fact, 1 am entirely certain from our enormous body of data that it is quite Impossible for individuals to absorb significant quantities of lead as the result of their contact with gasoline containing the commercial concentrations of tetraethyl lead.

X make this suggestion for t he reason that we have carefully investigated cases of all kinds that have arisen under conditions in which exposure to tetraethyl lead has been suspected.

The toxicologic information on these compounds with the exception of tetraethyl lead, has not been published.

As indicated above, our object is to inform, in the hope that on the evidence produced Government Departments will be satisfied that present regulations (if any) and recommended practices covering the use of tetraethyl lead will prove satisfactoi'y in connection with the use of tetramethyl lead and that therefore, providing these requirements are met no further action is necessary by the Oil Industry.

One point that should be mentioned is that in these plants the exposure ie limited entirely to tetraethyl lead and inorganic lead compounds, whereas, in those oases that have arisen from the cleaning of tanks, as you will find mentioned in the reprint sent you, there; is also a possible exposure to ethylene di bromide which you say know is u3d as a oarrying agent for tetraethyl lead in gasoline.

' As indicated above, our object is to inform, in the hope that on the evidence produced Government Departments will be satisfied that present regulations (if any) and recommended practices covering the use of tetraethyl lead will prove satisfactoi'y in connection with the use of tetramethyl lead and that therefore, providing these requirements are met no further action is necessary by the Oil Industry.

Among other craft fuels and one called "motor has been compressed by the upward contributions tetraethyl lead has aided fluid" for use in automobiles.
