Industrial Hygiene Digest May, 1964 termination of the exposure to lead, hastening removal of lead from the body through the use of edetate and dimercaprol, symptomatic therapy for encephalopathy, and the prevention of re-exposure to lead.

If the individual is regular in this respect the daily output of feces, over a period of several days to a week, when averaged for 24 hours, will show just how much lead he is taking in food and beverages (so long, of course, as this is the only source of ingested lead, i.e., no exposure to lead dust and no continuing occupational or other appreciable inhalation of lead other than that in the general ambient atmosphere).

(We had first investigated, at some length, the response to the Ingestion of lead and the patterns of intake and output of lead from the general environment.)

One is by acidifying lead sulfide residue from the oslde sufficiently to produce some lead sulfate, roasting the mix of lead sulfate and lead sulfide to attempt to produce e B.S.W.L. of proper chemical composition. 0007-SWP-000007113 Fag* -?

In ray opinion, they can all be covered by the same regulations, except that I would consider it advisable that the concentrations of tetramethyl lead, trimethyl-monoethyl lead, and di-methyl - di-ethyl lead in gasoline singly or in combination, should not exceed the equivalent, in lead content, of 3 m l , of TEL.

First, the elimination of lead from gasoline would not eliminate all lead from the atmosphere, because the lead in the atmosphere comes from many sources.
