Bioaccumulation of cadmium (Cd) by oval squid, Sepio- teuthis lessoniana, the relative contributions of Cd in water and food to bioaccumulation, and the distribution of cadmium among organs were studied. In a bioconcentra- tion test, oval squid was exposed to 0.2 mg Cd/l seawater for 14 days, then was reared in Cd-free seawater for 14 days. After the exposure and elimination periods, the Cd concentrations in the whole body were 3X10
