“…The enzymatic results from this study are in the same range as those reported for the same species in Cádiz Bay (Pérez et al 2004, Solé et al 2009), on the west coast of Portugal (Moreira et al 2006), in the Seine estuary in France (Durou et al 2007a) and in the Oued Souss in Morocco (Ait Alla et al 2006) (Table 2). In the Guadiana River and Ria Formosa Lagoon, CAT, SOD and GPX activities were similar to the ones reported for bivalves Mytilus galloprovincialis (Cravo et al 2009) and Scrobicularia plana (data not published) ( Table 2).…”

“…Overall, metal concentrations in N. diversicolor tissues are in the same range of those reported in Cádiz Bay in previous years (Solé et al 2009). Several industries that use metals have developed in recent years in the areas within the bay, namely manufacturers of car and aircraft components, which have resulted in a continuous input of metals into the bay , 2010, Carrasco et al 2003.…”

“…These antioxidant enzymes were activated due to the presence of high metal concentrations, principally cadmium. A metal pollution gradient exist at these sites, that includes discharges from domestic sources, offshore industries and shipbuilding, in which the presence of cadmium is a recent input into the bay with a high bioavailability from sediments (Pérez et al 2004, Solé et al 2009, Blasco et al 2010. Several studies have reported the enhancement of antioxidant enzyme activities in polychaetes to cope with metal stress both in laboratory exposures and in the field (e.g.…”

“…This anthropogenic pressure influences the structure and dynamics of the estuaries and saltmarshes of this area, mainly through mining, urban, agricultural and harbour effluents and discharges (Carrasco et al 2003, Pérez et al 2004, Almeida et al 2007, Solé et al 2009.…”

“…These quite abundant omnivorous organisms dwell in the sediment (often regarded as a long-term reservoir of contaminants), being crucial species not only due to the important role they play in the food web but also due to the remobilization of contaminant and nutrient loads linked to their burrowing and dietary behaviour (Amiard et al 2007, Durou et al 2007a,b, Gillet et al 2008. These features confer to N. diversicolor its resistance and consequent ability to inhabit metal-rich sediments, and thus its importance as a bioindicator of estuarine environmental quality (Moreira et al 2006, Poirier et al 2006, Gillet et al 2008, Solé et al 2009.…”

SUMMARY:The environmental quality of the southwest Iberian coast was assessed in different areas (Ria Formosa Lagoon, Guadiana Estuary and Cádiz Bay) focusing on metal contamination (Cd, Cu, Ni, Pb and Zn) in Nereis diversicolor whole tissues. In addition, associated toxicological effects were assessed using a multibiomarker approach combining several conventional biomarkers. The set of biomarkers selected included antioxidant enzymes (catalase, superoxide dismutase and glutathione peroxidase), metallothionein and lipid peroxidation. N. diversicolor from the Ria Formosa Lagoon, Guadiana River and Cádiz Bay responded differently to metal contamination with different biomarker responses showing a clear site trend, suggesting different sources and/or magnitudes of contamination. Cadmium was a source of oxidative stress in polychaetes, mainly in Cádiz Bay, with a significant influence on antioxidant enzymes and enhancement of lipid peroxidation. The highest MT concentrations were in the Ria Formosa Lagoon and in the Guadiana River, where there was a direct relationship with high nickel concentrations. Biomarker responses of N. diversicolor are useful tools for environmental quality assessment on the southwest Iberian coast, and more specific metal biomarkers should be included in future assessments.Keywords: biomarkers, metals, Nereis diversicolor, antioxidant enzymes, metallothionein, lipid peroxidation, southwest Iberian coast.RESUMEN: Biomarcadores en Nereis diversicolor (Polychaeta: nereididae) como herramientas de gestión de la evaluación del medio amBiente en el suroeste de la Península iBérica. -El estudio de la calidad ambiental de los ecosistemas costeros del SO de la Península Ibérica (Ría Formosa, estuario del Guadiana y bahía de Cádiz) en relación a la contaminación metálica (Cd, Cu, Ni, Pb y Zn) se ha llevado a cabo mediante el análisis del contenido de metales en Nereis diversicolor. Además, los efectos ecotoxicológicos fueron evaluados mediante una aproximación "multibiomarcadores", en donde se combinan varios biomarcadores convencionales. La batería de biomarcadores seleccionadas han sido: las enzimas antioxidantes (catalasa (CAT), superóxido dismutasa (SOD) y glutatión peroxidasa (GPX), metalotioneína (MT) y peroxidación lipídica (LPO). Los ejemplares de N. diversicolor recolectados en las distintas zonas, mostraron una respuesta diferente a la contaminación metálica, lo que sugiere diferentes fuentes y/o magnitud de la contaminación. Los niveles de cadmio estan directamente relacionados con las actividades SOD y CAT y los niveles de LPO. En el caso del níquel, sus niveles se hallaban correlacionados positivamente con los de MT en la Ría Formosa y en el río Guadiana. La integración de las respuesta de los biomarcadores en N. diversicolor ha demostrado ser una herramienta útil para la evaluación de la calidad ambiental de los ecosistemas costeros del SO de la Península Ibérica.

Cadmium sulfide (CdS) quantum dots have a number of current applications in electronics and solar cells and significant future potential in medicine. The aim of the present study was to examine the toxic effects of CdS quantum dots on the marine clam Scrobicularia plana exposed for 14 d to these nanomaterials (10 µg Cd L(-1) ) in natural seawater and to compare them with soluble Cd. Measurement of labile Cd released from CdS quantum dots showed that 52% of CdS quantum dots remained in the nanoparticulate form. Clams accumulated the same levels of Cd regardless of the form in which it was delivered (soluble Cd vs CdS quantum dots). However, significant changes in biochemical responses were observed in clams exposed to CdS quantum dots compared with soluble Cd. Increased activities of catalase and glutathione-S-transferase were significantly higher in clams exposed in seawater to Cd as the nanoparticulate versus the soluble form, suggesting a specific nano effect. The behavior of S. plana in sediment showed impairments of foot movements only in the case of exposure to CdS quantum dots. The results show that oxidative stress and behavior biomarkers are sensitive predictors of CdS quantum dots toxicity in S. plana. Such responses, appearing well before changes might occur at the population level, demonstrate the usefulness of this model species and type of biomarker in the assessment of nanoparticle contamination in estuarine ecosystems.

The polychaete Diopatra neapolitana is a cosmopolitan annelid that can robustly regenerate both its anterior and posterior body part depending on the position of the amputation. Previous studies demonstrated that body regeneration represents a sensitive and unspecific response to environmental stresses, including contaminants and climate alterations.The posterior body regeneration of D. neapolitana is thus a suitable, ecological and relevant biomarker in ecotoxicological and ecological risk assessment assays. Here we describe the amputation process, the monitoring of the regeneration process of the polychaeteD. neapolitana and the quantification of the impact of environmental stresses on its regenerative capacity.
