“…In the case of the Gironde estuary, it may be hypothesized that, although Zn bioavailability increases for a given salinity drop, the oysters became increasingly impermeable to Zn to such a n extent that overall uptake of Zn fell. Due to the contrasting biological role of Zn (essential) and Cd (toxic), it has been shown previously that regulation of their uptake was clearly different in various invertebrates (Amiard et al 198713 and literature cited therein).…”

The Gironde estuary has been shown to be the most Cd-contaminated area In France. Oysters Crassostrea gigas of different size classes were sampled from 3 sites between the mouth and 25 km upstream, to study the relative importance of natural and contamination factors on metal accumulation and metallothionein-like protein (MTLP) induction. The highest metal and MTLP concentrations were observed in the digestive gland. In all organs, the 3 metals were mainly cytosolic. An inverse relationship was generally observed between weight of soft tissues and metals or MTLP concentrations in the whole soft tissues, whereas the influence of weight on metal distribution among cytosolic and insoluble fractions was small. When oysters with similar weight of soft tissues were considered, no influence of salinity at different sites was found for Cu and Zn whereas the lowest soluble and insoluble Cd concentrations were observed at the mouth of the river. Salinity did not influence Cu and Zn distribution among the cytosolic or insoluble fractions whereas cytosolic Cd in gills and digestive gland (%) was higher at the mouth of the estuary than upstream. MTLP and metal concentrations were generally positively correlated except at those sites where metal concentrations were lowest. However when multiple regression analyses were performed, weight appeared also as a major or an important factor to explain vanations of MTLP levels, the prevalence of this natural factor versus contan~ination factors being different at ddferent sites.

“…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.…”

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.

SUMMARY: Organic and inorganic pollution can impact organisms directly and affect condition, growth and survival of juvenile fish which use estuaries as nurseries, and thereby affect marine adult populations quantitatively and qualitatively. Trace element contamination (Cu, Zn, Cd, Pb) in juveniles of commercial fish Solea solea, Solea senegalensis, Platichthys flesus, Diplodus vulgaris and Dicentrarchus labrax collected in putative nurseries of the main Portuguese estuaries (with diverse intensities and sources of anthropogenic pressures) was determined via atomic absorption spectrometry. Contamination was significantly different among species. Similar levels of contamination were found among estuaries, except for D. vulgaris. Cu and Zn concentrations ranged from 1.0 to 2.1 and 14 to 59 µg g -1 muscle dry weight respectively; while Cd and Pb concentrations were very low. The results indicate that juvenile migration to off-shore habitats is associated with low export of contamination, and no particular estuary increases the potential contamination of adult stocks. This knowledge is of the utmost importance in view of the ecological and economical value of these species and their use of estuarine areas as nurseries.Keywords: juveniles, nursery grounds, populations, anthropogenic effects, heavy metals. RESUMEN: Metales traza (Cu, Zn, Cd y Pb) en peces juveniles de las guarderías estuáricas a lo largo de la costa portuguesa. -La contaminación orgánica e inorgánica puede afectar a los organismos, a saber al estado fisiológico, crecimiento y supervivencia de los peces juveniles los cuales utilizan los estuarios como guarderías; afectando de forma cuantitativa y cualitativa a la poblaciones marinas adultas. La contaminación de elementos traza (Cu, Zn, Cd, Pb) en las formas juveniles de los peces comerciales Solea solea, Solea senegalensis, Platichthys flesus, Diplodus vulgaris y Dicentrarchus labrax recolectados en guarderías putativas de los principales estuarios portugueses (con diversos tipos e intensidades de presiones antropogénicas) fueron determinados por espectrometría de absorción atómica. La contaminación era significativamente diferente entre especies. Sobre todo se encontraron niveles similares de contaminación entre estuarios, excepto para D. vulgaris. Las concentraciones de Cu y Zn oscilaban desde 1.0 a 2.1 y desde 14 a 59 µg g -1 peso seco muscular, respectivamente, mientras que las concentraciones de Cd y Pb eran muy bajas. Los resultados indican que la migración de los juveniles a mar abierto está asociada a la baja exportación de la contaminación y que los estuarios no amplifican particularmente el potencial de contaminación de los adultos. En vista del valor ecológico y económico de estas especies y del uso de las zonas estuáricas como guarderías, este conocimiento es de vital importancia.
