Glass stopper con tainers will tend to trap some of the blood at the point of contact with the stopper, whereas rubber stoppered containers will contribute lead unless the rubber is carefully fabricated and free of lead pigments and other lead compounds.

The usual range of the concentration of lead in fresh vegetation of the type represented in the first seven of these samples is N 5325.01 s V Mr.

I refer you further to the chapter on lead in the last edition of the second volume of Industrial Hygiene and Toxicology (edited by Patty) as perhaps the best expression of the criteria for safe exposure to lead (tetraethyllead) as defined by the urinary concentration of lead.

Box #341 Baton Rouge, Louisiana 70S21 , Dear Doctor Bock: I have two very good reasons for wishing to have the information that can be obtained from the examination of the available data at the Baton Rouge plant concerning the concentration of lead in the blood of persons whose occupational exposure to lead has been limited to the organo-lead compounds.

Analytical data (urine and blood) demonstrated the significance of their absorption of lead, and then the mysterious source had to be found.

I do not know who sees more cases of mild lead intoxication than I do.

In any case, however, the extent of the decrease, especially that in the blood, suggests, without wholly proving the case, that the total quantities of lead accumulated in the bodies of these men - the so-called "burden" of lead - were not unusually large^lfoi^wiDLalso note, I am sure, that while the findings in the case of diminished considerably, this man is right on the edge of a potentially dangerous level of lead concentration in his blood.
