Or blatant advertising of a new lead compound might create a, competitive situation that would result in reprisals to the discredit of tetramethyl lead, or even tetraethyl lead.

The portable "Uni-Jet" Lead-In-Air Analyzer was revised to provide constant rate collection of tetraethyl (TEL) and tetramethyl lead (TML).

Incidentally, some little while ago I wrote to you to ask your opinion of the method recommended by Ethyl Corporation for the disposal of sludge from tanks containing leaded gasoline,in which they advocate the spreading of the sludge in the open air and which they declare becomes virtually lead free after about one month's exposure.

Toxicologic appraisal of lead: Dr.

The accepted practice of wearing lead gloves and apron indicates that the profession is aware of the radiation hazard to some degree.

Lead equivalent in weight to that introduced in 4 ml. of TEL can be added to gasoline, as TML or any mixture, so long as this weight of lead (Pb) is not exceeded.

First of all, let me point out that the period during which the balance experiments on human subjects have been conducted (in the general investigation of the significance of lead in the human environment), began in 1939, was shifted to the study of the inhalation of lead in the air in 1950, and focused on the problem of lead in the general ambient' air (as one of immediate importance) in 1959.

Scales and certain of his associates in the Research Laboratories of Ethyl Corporation in Detroit, in an effort to supply technical information pertinent to the nature and extent . of the potential hazard involved in the substitution of tetramethyl lead for tetraethyl lead in antiknock fluids.
