Stable isotope analyses, delta C-13 and delta N-15, of sewage tolerant benthic invertebrates seaward of a sewage effluent discharged in a marine embayment, the Firth of Forth, East Scotland, suggest that the polychaete worm Nereis virens is a suitable species for identifying biological assimilation of sewage derived organic matter. The sewage isotopic signal is nor strongly recorded in the sediment due to the combined action of tidal movement, wind-induced wave action and benthic invertebrate grazing of particulate matter on the sea-bed. delta C-13 Of the plankton is significantly different from the effluent, but delta N-15 is not which precludes its use as a trace.
