Dear Sector &** Priestori*
2 have received m n e
correspondence through the associated
Company
bimiteft which Indicates that there has boon some
discussion about certain lead analyses which you
requested in, the case of workmen engaged in the tailing
of dthyl Fluid with gasoline*
'
It occurs to m that it nay
be tries to refer to our own practice in this regard in ooiaisentliig upon the necessity for these analyses, w
have been supervising the activities of several thousand m n who are engaged in this work in the United States* and
wo believe from a practical point of view the clinical
ess!nation of these m@a is on adequate means of main
taining hygienic* control* On the other hand from tine to tine over a period of years, wo have selected a
group of these non and have studied their urinary and
fecal lead excretion with the idea, of determining whether
they trera absorbing abnormal amounts of lead* 2'believe X have sent you reports of the" results of the?? and other exa&lnat ions which demonstrate quite clearly that the occupational exposure of these men 10 negligible. As a result of these studies we arc quite sure that If the
equipment Is kept in order, and If the sen carry out their work in accordance with the regulations, there will b no lead exposure or lead poisoning, and there' will be
no abnormal results in the analyses of excreta.
2 do not wish to discourage
you on this account from asking any tests which you feel
are necessary to inform yourself properly as to the occu
pational lead exposure of m n under your supervision*
Consequently X feel it will b entirely proper for you to' 'have these analyses- sad once a year if you wish and pass the coat of these on as you did before* My only query in the matter has to do with the accuracy of the analyses which arc carried out. 2 should be very much
