Three samples of raw oil shale from the Green River formation of western Colorado were retorted under conditions simulating the Tosco II process, a potentially commercial process. The raw shales and all resulting retort products were analyzed for various trace metals in an attempt to ascertain migratory patterns and resulting distributions through the retort so that effective environmental control measures could be implemented if necessary. Some evidence of low-level fluoride, boron, and copper partitioning to the water fraction was found. Similar behavior of arsenic and zinc partitioning to the shale oil product was observed with the ramainder of the metals investigated predominantly retained in the spent fly ash. 20 references, tables.
