Uptake, time‐course dependent distribution and elimination of cadmium after intraovarian loading with 0.5 mg Cd kg −1 body weight was investigated in the pregnant Zoarces viviparus (L), to elucidate the dynamics in the maternal‐foetal exchange of cadmium. After 7.5 h 95% of the injected cadmium was eliminated from the ovarian fluid, and half‐life was calculated as T 1/2 = 100 (S.D. 48) min. It took 48 h to eliminate 95% from the serum, where the half‐life of cadmium was T 1/2 = 11 (S.D. 3) h. The concentration of cadmium in the embryos increased during the first 5 h postinjection. However, a decrease was observed during the latter part of the experimental period. The liver and kidney of the mother fish showed a continuous accumulation during the 72‐h period of investigation. The negative linear correlation between elimination from the serum and the uptake in the liver, was calculated to be r=−0.79.
