The Use of Limpets and Mussels to Biomonitor Chronic Pollution in North Corsica Port Areas (Mediterranean Sea): A Multibiomarker Approach

Résumé

Port areas are socio-ecosystems impacted by chronic mixture pollution linked to the maritime traffic, fishing activities, yachting, etc. Despite these, some marine species find advantages living there and are used to define the ecological state of the environment. In North Corsica ports, limpets (Patella sp.) were used as a bioindicator to determine the chemical contamination of environment and the eventual subsequent impacts on biota. The biomonitoring survey was conducted during two years in three ports areas (Calvi, Île Rousse and St-Florent) and in a reference location (STARESO marine station) to study spatial and temporal variations in responses of limpets facing chronic chemical stress. A battery of biomarkers of exposure (trace elements and organic pollutants) and biomarkers of effect that focus on oxidative stress, detoxification, neurotoxicity, immunity and bioaccumulation, were analyzed. The objectives were to assess pollution-induced effects in organisms, to evaluate the evolution and the chemical contamination in waters and to verify if the limpet could be used as a bioindicator of severe pollution (in the case of accident in port area). As a result, the sites selected in the study were defined as low contaminated and the generated stress on limpets was not important. However, in the case of severe contamination, limpets display some correlated response between biomarkers of exposure and biomarkers of effect. This organism is then able to recover after several months and could be used to biomonitor chronic contamination in the Corsica port area.
