Dear Doctor Keyers
The . analytical report herewith requires hut a feu words of interpretation-
The average of the two results on the blood, when found to be
0 .0 7:mg., er.more cf lead per 'luo grams, indicates abnormal
: ,
exposure to lead, whether confirmed by the urinary results or not.
esults on the blood above 0.03 ng'. per 100 grans are indicative. :
of 'potentially hazardous exposure, and the'.-higher they are above
this level the more hazardous is the exposure.
The urinary values, for samples of small volume ,vary normally . between U.ol and .l' mg. per liter, going evenga little higher
occasionally . Abnormally '-high .values -'in them,us Inc in association . with low or borderline values in the blood are likely to be but not necessarily, associated with very recent, and brief exposure, and therefore are t.o be regarded, with some suspicion.
On the basis of these principles the following comments are jus
tified in connection with this report:.
-

1. has been subjected to hazardous exposure to lead recent xy xuas. ssource of exposure should be Identified and- eliminated or reduced;
and ' 4 l H H M H i ^ ^ h & v t : been exposed to an extent that may- be hazardous. If continued, and these men should be watched. If they have been employed longer than :the other men engaged in similar work, the diffei-ence may be-merely ta matter of time. Other wise there Is something in their work that gives them greater expo sure than the others!

and.
may well have had
some very recent but brief exposure of relatively severe type. It
will be noticed that their blood values are a bit higher than most
of the others. These men seem to have greater exposure than your
comments would indicate, and if so, this may be a matter of house
keeping - that is, the conditions in their surroundings rather than
to their own work;
W It would appear that the conditions under which these men work are generally'.-'satisfactory-, but- one suspects that ,there are oceas-
