It has been suggested that gradual solar energetic particle (SEP) events enriched in ^3He and Fe result from the shock acceleration of remnant interplanetary material from previous impulsive flares. We test this hypothesis by comparing the number densities of Fe ions during quiet periods, ^3He-rich periods, and Ferich SEP events. We find that there is not a sufficient density of suprathermal Fe during typical quiet periods (or ^3He-rich periods) to account for the overall enrichment of Fe in and suggest other possibilities for interpreting these events.
