Reports covering other aspects of this analytical model (a lung clearance model for lead-210 and its daughters, and an overall model combining lung clearance, bodily retention and indirect contribution of lead-210 from inhalation, diet and background) are under preparation.

Assuming that your investigation does demonstrate that no lead is absorbed through the human skin from the use of lead-containing hair dyes, we do not believe that this would prove absolute safety.

I find it most interesting, but would like to make just one comment I do feel that when one is controlling lead absorption in industry it is useful to have a term to describe those men whose lead absorption is higher than is safe, but who are not yet suffering from lead poisoning.

My objection to the term "lead absorption" is a personal one in which my feelings are involved; the term has been used to describe persons who are not disabled or acutely 111, but are "leaded" and not really well.

He was constantly exposed to Lead in tetra ethyl gasoline analytical work, Sulfides, Hydrocarbons, Crude oils, arid mercury fumes.
