“…These results mean that barnacle shells do not reflect adequately metal uptake from seawater and should not be used to biomonitor or predict metal contamination in the environment. The bioaccumulation of metals in barnacle hard tissues involves the metabolic mechanisms related with the equilibrium of metal assimilation from phytoplankton and zooplankton diets and metal efflux rates, but probably also the mineralization processes during shell plates formation, when replacement of Ca by other bioavailable metals in the seawater may occur (da Silva et al 2004Silva et al , 2005Silva et al , 2009aHockett et al,1995Hockett et al, , 1997Ng et al 2005;Rainbow 2007;Rainbow andWang 2001, 2005;Rainbow and White 1989;Rainbow et al 2003Rainbow et al , 2004bViarengo and Nott 1993;Wang and Rainbow 2000Wang et al 1999;Watson et al 1995). Thus, bioaccumulation of metals in barnacle hard tissues may be masked by mineralization (Fig.…”

The concentrations of seven metals (Cd, Cr, Cu, Fe, Mn, Ni and Zn) were determined in coastal seawaters and soft and hard tissues of the barnacle Chthamalus montagui from the northwest coast of Portugal to assess the potential use of C. montagui as biomonitor of metal contamination. The results of this study showed that C. montagui soft tissues can be used for monitoring metal bioavailabilities in these coastal seawaters: (1) there were significant correlations (p<0.05) between the metal concentrations in soft tissues and their concentrations in seawaters and (2) barnacle soft tissues were sensitive to spatial variation of metal bioavailabilities, accumulating different amounts of metals in different locations. The range of concentrations in tissues were: 0.59-1.7 mg Cd kg −1 , 0.5-3.2 mg Cr kg −1 , 0.72-3.0 mg Ni kg −1 , 1.2-6.7 mg Cu kg −1 , 9-26 mg Mn kg −1 , 214-785 mg Fe kg −1 and 178-956 mg Zn kg −1 ; (3) mean logarithmic bioaccumulation factors (log BAF) of Fe, Cr and Cd were higher, 5.49, 4.93 and 4.46, respectively, than mean log BAFs of Mn, Zn, Cu and Ni, 4.03, 3.97, 3.74 and 3.61, respectively. In contrary, C. montagui shell plates were not a good matrix to monitor metal bioavailability in these coastal seawaters, with no significant correlations (p < 0.05) between metal concentrations in the shell and in seawater. Regarding the high Zn concentrations obtained in the coastal seawaters and C. montagui soft tissues, all seawaters from northwest coast of Portugal should be classified as "moderately/remarkably polluted".

“…Especially the concentrations of essential metals can be regulated within appropriate intracellular levels, for example during elevated metal exposure (Stoeppler and Nürnberg, 1979;Rainbow and White, 1989). This regulatory capacity is often species-specific and depends on physiological traits such as osmoregulatory capacity, excretion rates, the ability to eliminate metals through ecdysis, and induction of detoxification pathways (Engel, 1987;Viarengo and Nott, 1993;Engel et al, 2001;Ahearn et al, 2004;Rainbow, 2007). For example, the rockpool prawn, Palaemon elegans, is capable of maintaining its internal concentrations of~76 μg Zn g −1 dry mass and 125 μg Cu g −1 dry mass when exposed to up to 315 μg · L −1 Zn and 100 μg · L −1 Cu in seawater before a net accumulation starts (Rainbow and White, 1989).…”

“…Marine crustaceans are highly sensitive to mercury, copper, and cadmium, and only to a lesser extent towards nickel or zinc (Eisler and Hennekey, 1977;Devi, 1987). This separation in sensitivity reflects distinct physiological traits and characteristics of species for regulating internal metal concentrations through uptake, excretion, or induction of detoxification pathways (Eisler, 1981;Amiard et al, 1987;Viarengo and Nott, 1993;Rainbow, 1995Rainbow, , 2007Ahearn et al, 2004). Furthermore, abiotic or ecological factors, such as temperature, salinity, lifestyle, feeding mode, metal uptake route, or metal speciation influence rates of absorption and internal metal sequestration.…”

“…Industrial processes are major sources of anthropogenic metal pollution in the environment (Järup, 2003;Rainbow, 2007). Pollution often occurs locally, and variation among regions may depend on the composition and quantity of industrial discharges, as well as on the distance to the point source of pollution (Soto-Jiméneza and Páez-Osuna, 2001;Yuan et al, 2012;Gao et al, 2013).…”

The intracellular ubiquitin-proteasome system is a key regulator of cellular processes involved in the controlled degradation of short-living or malfunctioning proteins. Certain diseases and cellular dysfunctions are known to arise from the disruption of proteasome pathways. Trace metals are recognized stressors of the proteasome system in vertebrates and plants, but their effects on the proteasome of invertebrates are not well understood. Since marine invertebrates, and particularly benthic crustaceans, can be exposed to high metal levels, we studied the effects of in vitro exposure to Hg 2+ , Zn 2+ , Cu 2+ , and Cd 2+ on the activities of the proteasome from the claw muscles of lobsters (Homarus gammarus) and crabs (Cancer pagurus). The chymotrypsin like activity of the proteasome of these two species showed different sensitivity to metals. In lobsters the activity was significantly inhibited by all metals to a similar extent. In crabs the activities were severely suppressed only by Hg 2+ and Cu 2+ while Zn 2+ had only a moderate effect and Cd 2+ caused almost no inhibition of the crab proteasome. This indicates that the proteasomes of both species possess structural characteristics that determine different susceptibility to metals. Consequently, the proteasome-mediated protein degradation in crab C. pagurus may be less affected by metal pollution than that of the lobster H. gammarus.

“…In terms of biological tools, bioaccumulation studies using encaged organisms have gained importance for environmental risk assessment (Bervoets et al, 2005;Besse et al, 2012). Indeed, metal determination in organisms provides an integrative measurement of local metal bioavailability at the transplantation site insofar as the different exposure routes of transplanted organisms and their ability to regulate internalized metals and geochemical effects on metal uptake are taken into account in the bioaccumulation process (Rainbow, 2007;Verschoor et al, 2012;Lebrun et al, 2014).…”

-Dredging generates remobilisation of sediments contaminated by non-degradable compounds such as metals, to which aquatic organisms can be exposed. This study aims at assessing the environmental impact of sediments remobilised in the Rhine River (France) during the dredging of Marckolsheim dam by pumping/dilution in 2013 on metal speciation and organisms' exposure. The monitoring coupling chemical and biological tools was performed 2 years before dredging operation on 2 sampling sites, upstream and downstream from the discharge of pumping/dilution, to acquire data on the natural variability of labile (DGTas passive samplers), dissolved and particulate concentrations of Cd, Co, Cr, Cu, Ni, Mn, Pb and Zn in Rhine during full hydrological cycles. In parallel, size-calibrated zebra mussels were transplanted at both sites to monitor continuously metal bioavailability from particulate and dissolved fractions. This long-term monitoring allowed the establishment of reference baselines of Rhine water and mussels' contamination levels and subsequently, the detection of averred environmental changes due to the dredging. Indeed, Co and Mn accumulations in mussels exposed to the discharge were consistent with increasing labile species in Rhine whereas ones of Cr and Pb were likely due to an enhanced particulate bioavailability. Whatever the exposure route, the mussels recovered their basal metal contents 2 weeks after the end of dredging, suggesting a transient impact of sediment remobilisation on bioaccumulation. This long-term monitoring highlights the interest of coupling chemical and biological time-integrated tools for a better assessment of environmental risks because metallic exchanges between organisms and their media are complex and metal-specific.Keywords: active biomonitoring / Dreissena polymorpha / DGT / metal bioavailability / natural variability Résumé -Évaluation de la remobilisation de sédiments contaminés par des métaux dans le Rhin au cours du dragage d'un barrage grâce à un suivi chimique et biologique à long terme.
