Surgeon General which concluded "that there are at present no good grounds for prohibiting the use of ethyl (leaded) gasollne...provided that its distribution and uees are controlled by proper regulations.* | k t The 1925-26 committee was appointed after the industry suspended sale of leaded gasoline in May 1925, following some lead poisoning cases in a plant Involved In the manufacture and handling of tetraethyl lead.

With the exception of tetraethyl lead, and related organic compounds, its absorption through the skin or through abraded or lacerated surfaces may be considered neg ligible.

It is probable that domestic shortages would result which would -8- severely affect lead consuming industries such as the battery industry or the tetraethyl lead industry.
