The attached table was prepared to answer a question
by He
aI .skAed,
Lundgaard which was relayed by Lance Percival 4/3/81.
if there was a correlation between airborne C-8
and organic fluorine in blood. There is not a direct correlation
as with some materials where an exposure ona day may appear
directly or as a metabolite in the urine the next day. C-8
accumulates in the blood and is not readily eliminated from
the body. Therefore, .organic fluorine in blood samples is
usually the result of exposure over an extended period less
elimination which may vary between individuals depending-on
differences in body chemistry.
The data for monomer operators illustrates the
persistence of C-8. Seven long-service monomer operators who
may have been exposed to airborne C-8 had an average -organic
fluorine level of 0-35 ppm in their blood which is the same as
.the background level for 'organic fluorine given in the answer to
question 17 (". . . organic fluoride blood levels ranged up to
0.4 ppm."). We do not know if this was naturally occurring
organic fluorine or C-8. Three monomer operators.who had about
2 years monomer service preceded by 15 years fine powder service
had an average organic fluorine level o'f 5,9 ppn in their blood.
This must be a carryover from exposure in their fine powder
assignments* The level is similar to current fine. powder operators
who had organic fluorine in their blood samples ranging from
0.2 to 21.7 ppm.
