LEAD COM EiBg New York.

The COg content of the white lead product made at the White Lead Plant since the said invention was there put into use varies in normal operation of the plant from 11.72$ to 11.76$.

d e n t amouht of lead to cause lead poisoning

The puroo.se of our note in the Bulletin was to indi cate that there was an easily detectable difference between the amounts of lead found in the blood of lead poisoning cases and of non-lead poisoning eases.

As a part of the lead studies, the hygienic significance of the distribution and use of gasoline containing tetraethyl lead as a motor fuel has-been under investigation.

The latter and his colleagues in a study of a storage battery plant came to the conclusion that the daily __ ' * * 3 ** inhalation of 1.45 milligrams of lead would not produce lead poisoning within a year, hut might produce lead .

Heavy paste white-lead contains 91'i carbonate of lead and 9* i pure refined linseed oil.

It is fairly safe to assume that where lead absorption cannot be demonstra ted to occur, lead poisoning would not be expected

Children, like lead workers, may develop abdominal pain, constipation and vomiting.

Thus negative lead findings on this man at the present Including such things as blood changes, lead line and lead in the excreta have ho slgnlfi^ canoe whatever either positively or negatively.

To my mind a real under standing of the toxicology of lead and an evaluation of the danger from minute amounts of lead must eventually come from an understanding of the kind of changes which lead brings about in the organism^.

Both of these circumstances speak against lead intoxication.

The dilution of tetraethyl lead with gasoline also largely eliminates the danger of lead inhalation.
