Biomarkers are useful tolos to assess biological effects of pollutants and have been extensively used in Monitoring programs To determine Ecosystem health. In These programs, a wide range of environmental conditions are covered and sometimes, obtained data are difficult to interpret because of natural Variables are affecting biomarker responses. Among these variables, mussel ́ ıs reproductive status has been considered one of the most changing variablesbetween sites in a monitoring survey. Thus, the main aim of this work was to identify the effect that mussel reproductive status has on biomarker responses. For that purpose, mussels sampled at two periods in the reproductive cycle (reproductive and resting stages)were conditioned to the same laboratory conditions and exposed to fluoranthene (FLU) for three weeks. Studied biomarkers covering a Wide range of organism responses were included: bioaccumulation, physi- ological rates (clearance rate −CR-,absorption efficiency− AE-,respiration ...
