B. EP3DMI0I0GK 'STUDIES
(1) 1/25 - Medical Division Statement based on liver enzyme s t u % " . . . there is.no conclusive evidence of an occupationally
-------------- - related health problem among workers exposed to C-8."
(report expected in Oct.).
(2) July - Teflon area workers had no significant excess of heart attacks compared with rest of plant.
Xv
{3} July - Teflon area workers had
X
no significant difference
in blood pressure from a
control group with no Teflon
(or C-8) exposure
(adjusted for age, smoking,etc)
(4)August - 3M Medical Dept, published.a paper, "Health status'of plant workers exposed to fluorochemicals - a preliminary report." in the American Industrial Hygiene Association Journal.

(3) Sept, (4) 9/17
- Pine powder, granular and . PEP made using spray dried
C-8 in BDD tests. Dispersion polymerization reaction rate 10 - 15% below normal. Granular polymer thermal stability below normal. May be
a problem with operator acceptance because C-8 is very fine and clings to scoops.
- 3M representatives visited W to review spray dried C-8 evaluation. More semiworks evaluation of samples will be made before plant tests.
