The fluctuation dynamics in steady-state fragmentation and aggregation processes is analysed from a kinetic point of view. The fluctuations in the number of particles of size between x and , in a sample with average occupation number , appear to behave like sums of uncorrelated events: . The implications of this fact for the applicability of a mean-field description, and possible relation with intermittency phenomena in three-dimensional turbulence are discussed.
