Artificially fertilized eggs and newly hatched larvae of cod Gadus rnorhua L. were
exposed to 14C labelled naphthalene, phenanthrene, benzo(a)pyrene and 2. 4. 5. 2', 4', 5'-hexachlorobiphenyl
(PCB) for 24 h and thereafter transferred to clean seawater. Radioactivity in eggs and
larvae was measured at different times during exposure and after transfer to clean seawater. Maximum
accumulation was found with phenanthrene, whereas naphthalene accumulated only slightly in both
eggs and larvae. Naphthalene was, on the other hand, rapidly eliminated in contrast to the slow
elimination of the other more lipophilic components. Most of the radioactivity accumulated in eggs was
transferred to the larvae upon hatching. These findings show that cod eggs and larvae accumulate
lipophilic xenobiotics from seawater and that the components will be stored for long time even after
eggs and larvae are out of the polluted area.
