Kehoe began by describing the background development of the tetraethyl lead industry from 1924.

Drivers of cars using ethyl gasoline as a fuel and In which the concentration of tetraethyl lead was not greater than 1 part to 1,300 parts by volume of gasoline showed no definite signs of lead ab sorption after exposures approximating two years. 2.

Physical examination at this time disclosed no apparent illness as a result of handling tetraethyl lead.

Some time in the summer of 1929 the claimant as a result of an accident spilled a small amount of ES30 {which contained almost 2 ocs of tetraethyl lead per gallon) over one side of his face and, as he now claims, in his right eye.He had no apparent reaction at the time.

We ore hastening the Investigation on the effects of the diluted tetraethyl lead as rapidly as possible and will give you an early report.

The point is . whether or not the difference in symptoms is due merely to differences in the rate of absorption by the body or whether lead tetraethyl has a specific toxicity c its own.

Physical examination at this time disclosed no apparent illness as a result of handling tetraethyl lead.

. , 1927, and observed a mix made in the proportion of 2-1/4- c.c. lead tetraethyl per gallon of gasoline.

I shall be armed with all of the experimental data which we have obtained on all aspects of the tetraethyl lead matters.

.; The matter of questioning any of these men for the purpose of determining the existence of symptoms of tetraethyl lead poisoning is a somewhat delicate operation.

With the exception of tetraethyl lead, and related organic compounds, its absorption through the skin or through abraded or lacerated surfaces may be considered neg ligible.

Furthermore, variations in gasolines from different sources, and in various parts of the country, bring about a wide range of concentrations of tetraethyl lead required to bring the gasoline to a certain minimal anti-knock standard.
