Kinetics of bioaccumulation of Hg by Orechromis mossambicus were investigated in this study. We experimentally determined the assimilation efficiency (AE) of ingested prey, the uptake-rate constant from the aqueous phase, and elimination-rate constant of mercury. By the steady state of the exposure period, the Concentration Factor (CF) of Hg was 130.66 to 150.58. The biological half-lives at slow components between small and large fishs did not change significant, and were found to be 46.8-46.5 and 72.2-75.3 days. Predictions of Bio Concentration Factor (BCF) in O. mossambicus tissues using a biokinetic model and the measured AE and efflux rates ranged from 743.31 to 4825.95.
