Hippooratea recorded a aeries of attacks of lead colic in a lead miner and in the Second Century, A.

The work on normal lead, and on lead excretion in certain trades Is to my mind to most interesting part of our study. .

Four-day cold exposures to 30cc's of 4$ acetic acid leached 25 milli grams of lead; 30 cc's of applesauce leached 5 milligrams of lead; and 30cc's of tomato juice leached 4 hundredths of a milligram of lead (0.04 Big) Double dis tilled water leached no lead.

For all of these reasons, I believe that the distribution of any such booklet to the purchasers of leaded gasoline is unnecessary and unwise.

If the amount of lead actually presetti-^-hbrnbustlba gases is as small as re ported, tho'-boxiciusicns would not be unvalidated by a three-fold' correction factor, 3* The only question in toy raind relates to the accuracy of the values* If no load was found in the fifth absorber, there is still-the possibility that some load was present in h'Hcn-absorbabla form, I believe .that early experiments on the exhaust of an engine failed to account for all the lead input, end this was probably due to inability to remove tho lead quantitatively from the exhaust gases.

Your people should be warned of the necessity of exercising great care in the avoidance of lead exposure in dealing out tanks which have been used for the prolonged storage of leaded gasoline.

. - 1)eoeraber 6, 1957 Dr* K* Plantey 117 Ms Bus Michelet Alger* Bear Doctor Planteyj- I have received correspondence through the London office of Ethyl Export Corporation transmitting Information concerning a workmen In the plant of the Compagnie Algerlenne dea Petrolea who appfired to have been Intoxicated In some measure through lead absorption* I might say at the outset that I am somewhat skeptical of the diagnosis in this case* and although the symptoms recited in your letter of November 17th are suggestive* I am still doubtful of the diagnosis* Moreover the Quantity of lead reported as found in this man*s urine is within normal limits as given by methods of analysis which we employ* In any case I am Quit sure that if this man absorbed lead sufficient to produce the symptoms described, then he must have handled tetraethyl lead by methods which are not in accord with our regulations* If the regulations are followed, there should be no exposure whatever* Accordingly the principal matter of importance in relation to this case has to do with the care with which the work is being carried out* If the plant is inadequate and if the work is being done care lessly, it should be cheeked into and these bad conditions should be corrected* If this Is done, and If the man who was reported as ill Is now entirely well, and is willing to work In accordance with the regulations, there is no reason.
