Dear Doctor Weingarten:' _
In the absence of Dr, Kehoe I am taking the liberty of writing to you and making some comments about the analytical results on what appears to be the most recent samples of blood and urine which you have submitted to us.
My comments will be brief because I am sure Dr. Kehoe will want to discuss the results perhaps in greater detail on his return.
Briefly t h e r ^ ^ j n ^ ^ a d content of the blood and urine of only
one man,
is within a clearly safe range in reference
The concentrations o f ^ e a d i j ^ j h e blood and the urine of both ~ fend ^ H H H H | a r e in a dangerous range
consistent with intoxicatTor^ffflrwith current absorption.
The concentrations of lead In the blood of the five remaining men are at about the threshold where certainly no further lead absorption should be tolerated ivithout the threat of trouble. The results of the urine are in general consistant with those
of the blood and reflect current absorption.
With the exception o f ^ m H H f all of these men should be removed from any area where exposure to lead is anticipated.
Sincerely,
LWS:ac Enclosures cc: Dr. Kehoe
