No data have been published on the nature of exhausted lead compounds since the 1926-1930 reports of the U.S.- Bureau of Mines, Public Health Service, and British Ministry of Health, This paper is the first work in which the amounts, particle sizes and composition of exhausted lead have been determined.

A little later, Kehoe and Edgar expanded these experimental observations in to the field of commercial dietribution and use of leaded gasoline Ly undertaking study of the comparative lead exposure of unexpor.ed and exposed garage mechanics, drivers of cars, and filling station attendants.

But the successful survivors had gasoline engines which employed the Otto principle.

Kehoe has no records of tetra-ethyl-lead poisonings at the small plant of American Hesearch Laboratories, In., In or near Denver, in 1926.

It is the purpose of this statement to present and, so far as possible, to document the salient facts concerning the hygienic aspects of the occurrence and distribution of lead in the environment of citizens of the United States of America, with particular reference to the contribution made by the use of leaded gasoline.

INTRODUCTION : ;i ( . - It is the purpose of this statement to present and, so far as possible, to document the salient facts concerning the hygienic aspects of the occurrence and distribution of lead in the environment of citizens of the United States of America, with particular reference to the contribution made by the use of leaded gasoline.

The straight-run, thermal-cracked, catalyticcracked, polymerized, and natural gasoline are blended together in a continuous automatic 10 blending system where tetra-ethyl lead is added to giye a finished motor fuel, meeting vapor pressure, distillation, and octane specifications.

It was feared that this property, which could be expected to contribute significantly to the rate and extent of the vaporization of the lead compound out of commercial gasoline, might create an uncontrollable hazard for the handlers and users of leaded gasoline.
