So tar in 1970 nine cases of elevated blood lead in children have been discovered, This indicates that there are still places in Baltimore where a child can ingest lead paint, even though the amount ingested before discovery was not sufficient to cause poisoning symptoms, If a child eats a sufficient amount of lead paint he will show such signs of poisoning as pains in the abdomen, nausea and vomiting, irritability, lack of interest or persistant constipation.

Some Doctor at Mayos claims that he could have got lead poisoning in this way.

I have also had direct knowledge of six or seven deaths from acute organic lead poisoning in connection with the cleaning of storage tanks heavily contaminated with tetraethyl lead or its decomposition products.

Williams' article, in that Miss Conway's failure to mention "cases of lead poisoning which have resulted from tetraethyl lead in gasoline" is cited, presumably as an omission.

We have been looking for cases of lead poisoning from this source, and have been .studying the lead exposure incident to the use of leaded gasoline since 1925, and thus far neither we nor anyone- else have found or reported a single case of lead poisoning, except in connection with the manufacture and handling of concentrated tetraethyl lead or with accidental exposure to or contact with the compound.

We should be able to deal with all the material you have indicated in a direct and forthright manner, xvithout any great controversy, with the exception of the part indicated as ''latent lead poisoning and sequellae lead poisoning."

I am not even slightly interested in a palliative treatment of lead poisoning that will encourage industry to continue in the belief that lead poisoning is not much of a problem, since it is readily and successfully treated.

The fact that a definite cause for this peculiar disease cannot be found does not justify the conclusion that it was caused or influenced by lead poisoning, especially when t ere is inadequate proof teat a lead poisoning ever existed.

The Quantities of Lead Absorbed Under General Environmental Conditions, As Compared with Those Associated with the Danger of Lead Poisoning The quantities of lead found in the tissues and organs of persons in the general population (those who have not been subjected to occupational or other unusual environmental conditions, with respect to lead), and in transit, i.e., into, through, and out of the tissues, are not associated with any form of intoxication by lead that is known to physicians, investigators, or KF 0008220 -4 - physiologists.
