“…This is in accordance with previous studies on bivalves (Langston & Zhou 1987, Pavicic et al 1989, Evtushenko et al 1990). In contrast, the soluble fraction I-epresented only 23 and 28% of gill Cu and Zn concentrations in natural populations of Crassostrea virginica of the Patuxent River studied by Roesijadi (1994).…”

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.

“…To the best of our knowledge, this is the first time that Cd analyses have been made on the microphytobenthos of the Marennes-Oléron Bay, a biological compartment that is very abundant on all bare mudflats of this bay (Guarini et al 1998, Blanchard et al 2000. This microphytobenthos had a Cd concentration (1.22 µg g -1 dry wt) close to that measured in the planktonic diatoms collected from the Seine Bay (which is also subjected to chronic Cd pollution) and of planktonic diatoms collected in the Marennes-Oléron Bay (Miramand et al 1993(Miramand et al , 2001a (Bryan 1984, Phillips 1977, Langston & Zhou 1987. Among the molluscs, the bioaccumulation of cadmium does not seem to be linked to their taxonomic group, nor even trophic behaviour (Table 1).…”

The Marennes-Oléron Bay is subject to chronic pollution by cadmium (Cd) from the Gironde watershed. An ecosystem approach was used to study the fate of cadmium in the different biological compartments. The median Cd concentration was 0.4 µg g -1 dry weight for the 63 benthic species measured. When combined with the respective biomasses for the different species studied, we estimated that 7 kg of Cd is partitioned into the soft tissues of the benthic species in the bay. The majority of this cadmium was distributed between primary producers, mainly microphytobenthos (40%), and suspension-feeders, mainly oysters (40%). All other benthic species measured were associated with negligible masses of Cd. Two trophic levels contained 98% of the Cd: 3 kg was partitioned into primary producers (of which 77% is associated with the microphytobenthos) and 3.2 kg of Cd was distributed among all suspension feeders. The carnivores, including scavengers, concentrated less than 0.2 kg of Cd, suggesting an absence of biomagnification of Cd in the trophic food web of the bay. The microphytobenthic compartment was estimated to control the largest quantity of Cd (ca. 188 kg yr -1 ), suggesting an important role for the microphytobenthos in the biogeochemical cycle of Cd in the bay. The quantities of Cd associated with annual biological production in other biological compartments were low: 2 kg yr -1 for eelgrass which could represent a vector of Cd transfer to winter populations of Brent geese and 1.4 kg yr -1 for all suspension feeders, principally the cultivated Pacific oysters (64%) representing a vector of Cd transfer to humans. An ecosystem-wide budget for the quantities of Cd present in all the biological and physical compartments showed that the majority of Cd (1 t) is trapped in the upper 5 cm of the bay sediments, representing a potential risk for the oyster and shellfish cultivation in the bay.KEY WORDS: Macrophytes · Microphytobenthos · Macrofauna · Cadmium · Bioaccumulation · Trophic food web · Marennes-Oléron Bay Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 307: [101][102][103][104][105][106][107][108][109][110][111][112][113][114] 2006 cessing plant stopped metal production, the tailings were isolated, and the runoff water treated. Nonetheless, the remaining cadmium mass trapped in the sediments of the Lot River was estimated to be nearly 200 t in 1991 (Lapaquellerie et al. 1995). The Garonne River and Gironde Estuary, which are downstream from the Riou Mort and the Lot River, have been contaminated through the flux of eroded, contaminated bottom sediments (Latouche 1988, Boutier et al. 2000. Even if the Cd fluxes have decreased since 1985 as distance from the Gironde Estuary increased (RNO 2000), they remain important, and are currently estimated at 4 to 5 t of dissolved cadmium per year. In the estuarine environment, cadmium sorbed on sediment particles may desorb as the water salinity increases (Latouche 1988, Lapaquellerie et al. 1996, Boutier et al. 2000...

“…The cadmium uptake rate in Littorina littorea reported by Langston & Zhou (1987) appears very low compared with that reported by Amiard et al (1987) and the results of the present work (Table 5). Langston & Zhou (1987), however, exposed the periwinkles in tidal tanks, and as the degree of accumulation is related to the immersion time (Langston & Zhou 1987), the difference in uptake a Calculated from regression line Mature mussels rates can probably be explained by the different exposure procedures. Salinity differences may explain why uptake rates in the present study exceed those of Amiard et al (1987).…”
