Lundgaard which was relayed by Lance Percival 4/3/81. He asked 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 one 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 She data for nononer eperators illustrates the deilfifmeirneantcieosn wihnicbhodymaychveamirsytrbye.tween individuals depending -on persistence of C-8.
