“…'Mussel watch' programmes have been initiated in many parts of the world, but unreflected 'mussel madness' has received severe criticism (White 1984). It becomes increasingly clear that initial studies are required to prove the indicator ability of organisms to be used in monitoring: 'There is no justification for simply assuming that any new untested species can act as an efficient bio-indicator' (Phillips & Segar 1986). The mussel is neither a new nor an untested indicator.…”

Juvenile blue mussels Mytilus edulis were cultivated in flow-through aquaria to investigate the influence of dissolved cadmium on cadmium accumulation (in terms of the Cd/shell-wt index). Where the ratio (by weight) of dissolved Zn to Cd remains within the range 25:l to 60:1, accumulation of Cd is not significantly influenced by dissolved Zn. Higher levels of concomitant Zn reduce the Cd/shellwt index. A lower ratio of Zn to Cd may slightly increase Cd accumulation. The Cd/shell-wt index is proportional to ambient levels of dissolved Cd up to 100 yg 1-' There were no significant effects on growth up to ca 30 pg 1-' Cd. Results corresponded to earlier experimental work and to field surveillance data reported in the literature. A procedure is suggested by which the concentration of dissolved Cd In natural environments may be estimated from 'mussel watch' data (Cd body burden, shell weight) and salinity. Cd accumulation in the mussel is described by the integral of the Cd/shell-rut index with growth of shells by weight. A model of biochemical accumulation of metals requires laboratory and field transplant experiments to be designed such that considerable growth is allowed in a new environment in order to approximate a new balance of metal residues in organisms in relation to ambient levels.

“…Marine bivalves, including mussels, clams, cockles and oysters, are known to accumulate heavy metals in their tissues from metalpolluted environments (Goldberg et al, 1983) and are therefore used as good biomonitors and bioindicators for coastal metal pollution and ecotoxicology (Phillips and Segar, 1986). The oyster Crassostrea hongkongensis has shown its capability to accumulate various metals, such as Cd, Zn, and Cu, to significant levels in its tissues (Liu and Wang, 2012).…”

H NMR a b s t r a c tMetal pollution has been of great concern in the estuaries in Southern China. In this study, metabolic differences between oysters Crassostrea hongkongensis from clean and metal-polluted sites were characterized using NMR-based metabolomics. We collected oyster samples from one clean (Jiuzhen) and two metal polluted sites (Baijiao and Fugong). The metal concentrations in oyster gills indicated that both the Baijiao and Fugong sites were severely polluted by several metals, including Cr, Ni, Cu, Zn, Ag, Cd and Pb. In particular, Cu and Zn were the major contaminants from the Baijiao and Fugong sites. Compared with those oysters from the clean site (JZ), metal pollution in BJ and FG induced disturbances in osmotic regulation and energy metabolism via different metabolic pathways, as indicated by different metabolic biomarkers. This study demonstrates that NMR-based metabolomics is a useful tool for characterizing metabolic responses induced by metal pollution.

“…One factor that can demonstrate the potential of organism as a good biomonitoring agent is the correlation between the concentration of a pollutant and others in its environment (Phillips and Rainbow, 1993;Phillips and Segar, 1986;Rainbow, 2006). Since the geochemical characteristics of a sediment have an major effect on the potential bioavailability, the mobility and toxicity of elements in aquatic organisms (Tokalioglu et al, 2000), assessing distribution patterns of these contaminants play an important role in understanding the fate and effects of metals in the environment (Krupadam et al, 2006).…”

The relationships are evaluated between the heavy metal species in sediments and the accumulation by the soft tissues of Saccostrea cucullata collected from the northern and southern coasts of Qeshm Island, Persian Gulf. The sequential extraction technique was employed to fractionate the sediment into non resistant and resistant fractions. Data from sequential extractions indicated that the metals were mainly associated with the residual fraction at the north coast and with non residual fractions at the south coast. The results showed that the best correlations were observed between heavy metals concentrations in soft tissues and the fractions in the southern sediment. Note that the bioavailability of trace metals is influenced by the chemical characteristics and properties of the sediment. Therefore, the present results generally supported the use of soft tissues of S. cucullata as a more accurate biomonitoring organism for Cu, Pb and Cd in sediments from the southern coast of Qeshm Island, Persian Gulf.
