“…Serafim et al (2002) reported that MT expression in gills of Cd-exposed mussels was significantly higher at higher temperature, while similar temperature dependent Cd accumulation was reported by Serra et al (1999). Greater Cd accumulation during the summer months was also observed in the study on Crassostrea virginica as a sentinel organism (Zaroogian, 1980). It could be, thus, presumed that during summer season accumulation of Zn and Cd was increased in gills, either as a result of higher availability of these metals in the dissolved state, higher temperature of seawater, or due to the increase of the diffusion rate, consequently leading to MT induction.…”

“…Cadmium has the lowest correlation coefficient (0.62) with the first component. It is not surprising, since previous findings indicate that Cd accumulation is highly related to its concentration in seawater (Zaroogian, 1980;Cossa, 1988). Food is less important source of Cd to marine invertebrates (Kerfoot and Jacobs, 1976).…”

A study performed over 12 months with caged mussels M. galloprovincialis in the coastal marine zone which is under the urban pressure, reveales a temporal variation of digestive gland mass which causes "biological dilution" of cytosolic metallothionein (MT) and trace metal (Cd, Cu, Zn, Fe, Mn) concentrations. The dilution effect was corrected by expressing the cytosolic MT and metal concentrations as the tissue content.

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.
