The crux of the hygienic issue, stated in the briefest possible terms, lies in the possibility that the quantity of lead absorbed into the human body under conditions associated with a larger than usual intake of lead via both the alimentary and respiratory tracts, during any part or all of the span of human life, may lead to the progressive accumulation of a potentially or actually dangerous burden of lead in the body.

The - 2- flesh (and milk) of leaded cattle do hot contain hygienically significant amounts of lead, because of tkefget that most of the lead is in the skeleton.

Our study has concentrated on three segments of the lead industry: the primary and secondary lead producers and lead-acid battery companies. \ Although our analyses will not be completed until mid-March, we have been able to develop some im portant tentative conclusions concerning the primary and secondary lead industries, which account for all U.S. lead production.
