Internal Correspondence /tfU U -o M ia To: P . F. Riehle - Spec. Chem. - 41-1 From: D . E. Roach, M.D. - Medical - 220-2E-02 Subject: Inorganic Fluoride Determinations Date: April 9, 1984 3M I am enclosing a copy of the inorganic fluoride test results on some Bldg. 15 personnel. The samples tested were from previous blood specimens dating back to 1980. The most recent were in November of 1983. Our interest in this followed the rise in organic fluorine determinations in some Bldg. 15 personnel. The question was whether or not there was an increased opportunity for exposure to inorganic fluoride in this group. The enclosed test results would not indicate an increase inorganic fluoride among this group of individuals. cc: D. D. Dworak - Chem. 41-1 E. Fasbender, R.N. - Medical - 116 S. D.
