The trophic transfer of pyrene metabolites was evaluated by a 2-month exposure of the freshwater annelid Lumbriculus variegatus (Oligochaeta) to pyrene, followed by feeding to juvenile brown trout (Salmo trutta). The results obtained by scintillation counting (SC) proved that the pyrene metabolites produced by L. variegatus were transferred to juvenile S. trutta through diet. More detailed analyses by LC-FLD (liquid chromatography with fluorescence detection) showed that an unknown pyrene… CONTINUE READING
