Resumo: 	The aim of this study was to evaluate the seasonal variations of six biomarkers on Mytilus galloprovincialis, using comparison with physiological index and chemical contamination levels on two sites of  Mediterranean sea. The seasonal variations of acetylcholinesterase (AChE), DNA adducts, benzo(a)pyrene hydroxylase (BPH), heat-shock proteins (HSP), metallothioneins (MT) and multixeniobiotic proteins (MXR) were estimated over a two-year period, on mussels which were sampled in Carteau (original site) and La Fourcade (transplanted organisms). Carteau, an industrial site, presents higher contamination levels (HAP, PCB, heavy metals) than La Fourcade, an urban area. The PAH profiles underline a strong spatio-temporal variability of levels and sources of contamination. For each biomarker, background levels and coefficients of variation were estimated over two years. Sorne biomarkers show very high coefficients of variation (MXR and MT), mainly on Carteau. This variability seems to be in relation with more variable environmental conditions and sporadic anthropogenic in this site. No significant difference in biomarkers responses, taken separately or integrated according to a composite index-number IBR (Intergrated Biomarker Response), was found between the two sites. The same result was obtained with physiological indexes (index of gonadic growth and index) which is put in light the adaptation abilities of the transplanted mussels.
