Several groups of zooplankton from the coasts of California, British Columbia, and in the Arctic, including copepods, euphausiids, amphipods, crab zoea, ctenophores, and jellyfish rapidly took up [3H] benzpyrene, [14C] benzpyrene, [3H] methylcholanthrene, and [14C] aphthalene from seawater solution. These hydrocarbons were metabolized to various hydroxylated and more polar metabolite by crustaceans but not by ctenophores or jellyfish. Up to 22 x 10- 4 µg of benzpyrene was ingested by the temperate water copepod Calanus plumchrus, and transfer of this copepod to fresh seawater resulted in the discharge of most benzpyrene with less than 1 x 10-5 µg remaining after 17 days. When depuration was continued beyond 17 days, no further hydrocarbon loss was observed. Calanus hyperboreus from the Arctic took up to 11 x 10-4 µg of [3H] benzpyrene and a 28-day depuration experiment still showed the presence of benzpyrene in the copepod although again less than 1 x 10-5 µg.
