Seasonal variations of a battery of biomarkers and physiological indices for the mussel Mytilus galloprovincialis transplanted into the northwest Mediterranean Sea

Tracing sewage and natural freshwater input in a Northwest Mediterranean bay: Evidence obtained from isotopic ratios in marine organisms

“…The physiological indices of the mussels showed temporal patterns, increasing in weight during the summer and decreasing in the winter. This result is consistent with a previous caging study done in the Golfe-Juan bay near our station R (Bodin et al, 2004). This annual cycle could explain the homogeneous isotopic signature observed in mussel tissues in the month of November, during which reserve tissues can be remobilized to meet the nutritional balance in response to food shortage.…”

“…From a global standpoint, the coastline of the Côte d'Azur is strongly urbanized, and the bay of Golfe-Juan has been considered to be 'subject to urban contamination' by previous studies (Bodin et al, 2004). Fig.…”

Evaluation of Multixenobiotic Resistance in Dreissenid Mussels as a Screening Tool for Toxicity in Freshwater Sediments

“…The fairly high precision in the measurement of MXR activities per treatment, as indicated in previous studies (Bodin et al 2004;Pain and Parant 2007), most presumably relates first to the fact that the test organisms belonged to a genetically uniform population and were collected from an anthropogenically undisturbed habitat. Second, in the previous exposure, the mussels were acclimatized in unpolluted and unfiltered lake water (with food-deprivation) for 5 days.…”

The lysosomal stability as a biomarker for the determination of pollution in aquatic environments

“…In this context, the use of biomarkers which are able to detect the presence as well as the toxic effects caused by those pollutants is increasing in importance and is being increasingly used. The biomarkers, according to Bodin et al (2004), can be defined as the measurements carried out in the biological liquids, cells or tissues which indicate, in biological or cellular terms, the presence of contaminants or the magnitude of the response of organisms to their toxic effects. According to Bodin et al (2004) and Pfeifer et al (2005), the biomarkers as the enzymatic induction of cytochrome P4501A, inhibition of the activity of acetylcholine esterase, integrity of DNA and induction of metallothioneins have been used in the monitoring of the ecological impact of various pollutants in the aquatic environments.…”

The search for simple and cheap biomarkers has led to the physicochemical and/or histopathologycal studies of the lysosomes which are capable of detecting the slightest cellular damage resulting from the exposure to toxic polluting agents, mainly those with lipophilic characteristics such as the polycyclic hydrocarbons and their derivatives (Köhler et al 2002).…”
