Nassau S m e ltin g and R e fin in g Company, December 23, 19^4 William Weingarten, M.D, Nassau Smelting and Refining Company 1 Nassau Place Staten Island Ts New York Dear Doctor Weingartent ' _ 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 thej^^jn^^ead content of the blood and urine of only one is within a clearly safe range in reference The concentrations o^^^a^^^he blood and the urine of both fand fllHHHHH^are in a dangerous range consistent with intoxTcacTor^fflHrwith 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 without the threat of trouble. The results of the urine are in general consistent with those of the blood and reflect current absorption. With the exception of all of these men should be removed from any area where exposure to lead is anticipated. Sincerely, LWSiac Enclosures cc: Dr. Kehoe Lester W. Sanders, Sr., M.D. 0018717 tr9' ipnao&m K 0018718 - w CO i&. & It cr H & :ccTt 2 & id JHO* tM-b* t-tJ ocr i*4 *0 O ^04 *s sd M Sof cr cs *T> M Ht, <i HO o * M 05*' ccft sH;* i-J 0 M JI-H* t-J Si* S* 0 - 8J n 21 ct S < 4 o 25 p^? c m 3M H* H0d C*d?
