摘要

Bioaccumulation of ~65Zn and ~109Cd by the cuttlefish Sepia officinlis L. was studied at dif- ferent stages of its life cycle, i.e. in embryos, juveniles and adults, following exposures via sea water, sediments and food. Cuttlefish eggs efficiently accumulated both elements from seawater with bio- concentration factors of 79 for ~65Zn and 46 for ~109Cd after 11 d exposure. Most of the radiotracers were found in the capsule membrane of the eggs, demonstrating that the capsule acts as a shield to protect embryos against metals. Junveniles and adults efficiently bioconcentrated both radiotracers from sea- water, with the muscular tissues containing 84/100 of the total ~65Zn and 62/100 of the total ~109Cd.
