摘要: 1. Eggs of herring(Clupea harengus), flounder(Platichthys flesus), and garpike(Belone belone) were incubated in cadmium contaminated water (0.05–5.0 ppm) newly hatched larvae analyzed for contents. 2. Cadmium residues dependent on concentrations employed during incubation. 3. Cadmium contents flounder herring (0.7–2.3 ng Cd/0.1 mg dry weight) two orders magnitude higher than inBelone belone under the same conditions (0.0017–0.0185 weight). 4. Cadmium held increased with exposure time. 5. Cadmium exposed to 8 days one order contamination kept similar (max. value 48 weight; max 5.4 weight). 6. Cadmium ofBelone juveniles at 0.05 ppm Cd 30 significantly control specimens.
