“…The initial concentration (average ± SE) of Cd in mussels from AC (0.56±0.09 mg kg -1 ) was one order of magnitude above those from GB (0.01±0.001 mg kg -1 ). Differences of this magnitude were reported previously for mussels in the same areas (e.g., Francione et al, 2004;Lino et al, 2016). Mussels from AC exhibited a 6-times concentration decrease within the first month of T1 (p < 0.05), maintaining relatively constant values along the following T1 samplings.…”

“…The polluted site was located in Guanabara Bay (GB), which is the most Previous research revealed that the metal-polluted GB can present comparatively low concentrations in organisms than the nearly-pristine AC coast, since GB eutrophication causes lower bioavailability, e.g. for Cd Lacerda, 1992;Francione et al, 2004;Lino et al, 2016), Pb and Ni Lacerda, 1992). An inverse trend was observed for Mn Lacerda, 1992;Lino et al, 2016) and…”

The aim of the study was to determinate the level of lead, cadmium and mercury on the edible part of Peruvian scallop (Argopecten purpuratus Lamarck, 1819) and mussel (Aulacomya ater Molina, 1782) from 2009 to 2012 in the major production areas of Peru and to compare the results with the maximum levels set by the European Union (EU) and consequently evaluate any health risks for consumers. Peruvian scallop samples from suspended culture were extracted from growing areas of Sechura, Samanco and Paracas. Mussel samples were extracted from natural banks from Marcona and Atico. THQ (target hazard quontient) values for Pb, Cd, Hg in Peruvian scallops, plus Pb and Hg in mussels were less than 1 (even less than 0.25), unlike Cd in mussels from Marcona and Atico which exceeded the maximum level allowed and presented THQ values greater than 1, representing a possible health risk. A maximum weekly consumption rate was estimated. ResumenEl objetivo del estudio fue determinar los niveles de plomo, cadmio y mercurio en la parte comestible de la concha de abanico (Argopecten purpuratus Lamarck, 1819) y el choro (Aulacomya ater Molina, 1782) en el periodo 2009 al 2012 en las principales áreas de producción del Perú y comparar los resultados con los niveles máximos establecidos por la Union Europea y en consecuencia, evaluar los riesgos para la salud de los consumidores. Las muestras de concha de abanico fueron extraídas de cultivos suspendidos ubicados en Sechura, Samanco y Paracas. Las muestras de choro fueron extraídas de bancos naturales ubicados en Marcona y Atico. Los valores de THQ (cociente de riesgo) para Pb, Cd, Hg en concha de abanico, asi como el Pb y Hg en choro fueron menores que 1 (incluso menos de 0.25), a diferencia del Cd en choro de Marcona y Atico que excedieron el nivel máximo permitido y presentaron valores de THQ mayores a 1, lo que representa un posible riesgo para la salud. Una tasa máxima de consumo semanal fue estimada para estos recursos.

“…As filter feeders living most of their lives attached to a substrate, bivalves are exposed to constant biologically available pollutants over an extended period of time [42][43][44]. They have been studied as biological models to assess the impact of pollution in the environment and used as a biomonitoring "tool" due to their capacity of bioaccumulating high concentrations of trace metals, mostly in soft tissues such as gills and digestive gland [45][46][47]. The large surface of the gills and their involvement in gas exchange and feeding processes bring bivalves to constant and intimate contact with their environment where pathogens may also find their route of entry and encounter the bivalve first-line immune defense reactions.…”

Deep-sea environments are, in some cases, largely unexplored ecosystems, where life thrives driven by the geochemical features of each location. Among these environments, chemosynthesis-based ecosystems, in the Mid Atlantic Ridge, have an exclusive combination of high depth, high sulfur, and high methane concentrations. This is believed to modulate the biological composition of vent communities and influence the overall vent animal transcriptional activity of genes involved in adaptation processes to extreme environments. This opens, thus, the possibility of finding gene expression signatures specific to a given hydrothermal vent field. Regardless of the extreme physicochemical conditions that characterize deep-sea hydrothermal vents, the animals dwelling around the vent sites exhibit high productivity and thus must cope with toxic nature of vent surrounding, seemingly deleterious to the animals, while developing surprisingly successful strategies to withstand adverse environmental conditions, including environmental microbes and mechanical stress whether ensuing from animal predation or venting activity. The deepsea vent mussel Bathymodiolus azoricus has adapted well to deep-sea extreme environments and represents the dominating faunal community from hydrothermal vent sites in the Mid-Atlantic Ridge, owing its successful adaptation and high biomasses to specialized exploitation of methane and sulfide sources from venting activity. Its extraordinary capabilities of adapting and thriving in chemosynthesis-based environments, largely devoid of photosynthetic primary production and characterized by rapid geochemical regime changes are due to symbiotic associations with chemosynthetic bacteria within its large gills. In an attempt to understand physiological reactions in animals normally set to endure extreme deep-sea environments, our laboratory has undertaken, for the last few years, a series of investigations, aimed at characterizing molecular indicators of adaptation processes of which components of the host defense system has received most attention. This study reviews recent advances on the characterization of molecules and genes participating in immune reactions, using in vivo and ex vivo models, to elucidate cellular and humoral defense mechanisms in vent mussels and the strategies they have adopted to survive under extreme environments.
