[9-14 c] Phenanthrene was administered to Norway lobster, Nephrops norvegicus,
intragastricly and the radioactivity in different tissues were measured at
intervals using a scintillation counter. The radioactivity was rapidly accumulated
in the tissues and the highest concentration was measured 1 day
after administration. Most of the radioactivity had disappeared 28 days after
the administration.
The metabolites of phenanthrene were isolated from the green gland, gonads
and intestine. The analyses of the TMS-derivatives of the metabolit.es were
performed using a computerized gas chromatograph mass spectrometer. A total
of six metaboli.tes were isolated and identified. Quantitative studies were
carried out using selected ion monitoring. The main metabolite found was
9,10-dihydro-9,10-dihydroxyphenanthrene which constituted 78, 95 and 64% of
the total metabolic products in green gland, gonads and intestine, respectively.
In green gland 41% of the metabolites were conjugated, in gonads 50%
and in intestine 23%.
