Poster Kennedy who made a tentative diagnosis of lead poisoning after having made an examination and after having had an analysis of the patientas urine made by Dr* DeSanto of Hew York* Dr# DeSanto reported on one occasion a concea- tratlon of 0*11 milligrams of lead pefc liter* It was solely on the basis of the neuritis plus the lead analysiswhich suggested abnormal lead absorption which resulted in the diagnosis of lead poisoning.

It produces a clinical pioture of lead poisoning, which is different from that associated with any other lead compound, as you will see from the article describing the clinical tetraethyl lead poisoning.

Underwood - (2) - May 4, 1949 with cases of lead poisoning on your hands.

'W . f Extract from Abadan Memorandum Mo 36127 dated 14-5-45 Subject: Lead Hazard.

The lead pigments (W-l V-104) are somewhat larger than optimum size* which detracts further from their hiding power* The three white pig ments* white lead carbonate (W-104), zinc oxide (W-33, W-219* W-17 2;* and titanium dioxide (see chart)* illustrate a fundamental property of pigments* namely their degree of chemical reactivity with the ve hicle and with the acidic compounds which form in the film as it dries and ages* White lead and zinc oxide are reactive pigments* titanium dioxide is a non-reactive pigment.

There mu3t first of all be a sufficiently high con centration of organic lead and the men must be in the tank for a sufficient length of time, the temperature must be high enough to volatilize the lead and the men must have failed to wear protective equipment.

At that time, from the information gathered and his condition, we were lead to believe that something be sides lead poisoning was his trouble.

There must first of all be a sufficiently high con centration of organic lead and the men must be in the tank for a sufficient length of time, the temperature must be high enough to volatilise the lead and the men must have failed to wear protective equipment.

Veen ago, the paint industry made products containing quantities of lead pigments and compounds which,if ingested, especially by children, could produce lead ooitoning with its attendant hazardous effects.

We have studied this problem with a great deal of care, and perhaps I should point out briefly what seems to occur* Under the conditions of storage of leaded gasoline in tanka, there la a 3light decomposition of tetraethyl lead in the formation of organic lead compounds in the sludge at the bottom of the tank, which seem to be capable of reforming small quantities of tetraethyl lead.

I have not discussed lead chemical or lead electrochemical meetigns -with Worcester or Passmore.
