Also recommended were studies of the lead content of human organs, of the particle size distribution of atmospheric lead, of the estimation of lead levels in blood and urine, and of the propor tion of lead absorbed from cigarette smoking.

To do this I repeated the gasoline lead regressions, and used them to remove the variance due to gasoline lead exposure, which is about 85% of air lead exposure.

coo- tainio| lead, and from lead in meteorites.

LEAD World smelter production of lead was a 1939 as in 1938.

It is a symbol that may be specified easilv in purchasing calking lead, and lead so stamped cost no more than ordinarv lead.

(c) "Lead Smelting and Refining" as used herein is defined to mean metallurgical and/or chemical treatment of lead ore, lead concentrates, lead bearing scrap, and/or drosses and any other lead bearing material into "pig lead," and/or "antimonial pig lead."

In line 6 from the bottom of this same page, the statement is made that workers in.the lead trades are exposed to lead primarily in the form of contaminated air.

Workers exposed to an average lead naphthenate concentration of 96 ug/m3 had a mean blood-lead level of 63 ug/dL.
