Relationship Between feeding-induced ventilatory activity and Bioaccumulation of dissolved and algal-bound cadmium in the Asiatic clam corbicula fluminea

摘要

The influence of feeding-induced ventilatory adaptation on cadmium accumulation patterns was analyzed in quiescent Asiatic clam Corbicula fluminea studied in steady-state conditions at 15°C and 25°C and in air-equilibrated water. Ventilatory Activity, algae inflow rate, amounts of inspired dissolved and algae-bound Cd, and whole-body and tissue-specific metal concen- trations were studied during a 15-d exposure period at a low dissolved cadmium concentration of 2 μg/L and various algal Concentration of Scenedesmus subspicatus. Great care was taken not to externally stimulate animals.
