In this current investigation the accumulation and elimination of copper (Cu) and lead (Pb) by Macrobrachium lanchesteri were examined in the laboratory. Animals were exposed to different concentrations of metals for 96 h to allow uptake and then transferred to clean water for elimination (96 h). The accumulation of Cu and Pb in M. lanchesteri was observed to be rapid and bioaccumulation increased with increasing metal concentrations in the water and with exposure time. In the elimination study, Cu and Pb were found to be eliminate rapidly from M. lanchesteri. Metal accumulation and elimination patterns in this organism are discussed.
