“…Metal concentrations in the lower Tamar are -1 pg Cu 1-l, < 0.5 pg Cd I-', -0 0.5 pg Fe 1-' and -8 pg Zn 1-' (Stebbing et al, 1983). If it is assumed that the higher concentrations of Cd and Zn in the tissues of Swansea mussels reflects a proportionately (2-fold) higher metal concentration in the water at this site, then these concentrations (-1 pg Cd 1-' and -16 pg Zn 1-l) are well below the EC,, values recorded by Stromgren (1982). Myint and Tyler (1982) examined the effects of 98 d of exposure to Cu, Cd and Zn (initial exposure concentrations 50, 50 and 200 pg 1-' respectively) on the gametogenesis of Mytilus edulis collected from Mumbles, Swansea Bay.…”

“…For example, Stromgren (1982) determined the exposure concentrations of metals which resulted in a 50 5% reduction in the shell growth (EC,,) of Mytilus edulis after 10 to 22 d. The EC,, values were 3 to 4 pg Cu 1-l, 60 pg Zn I-', 100 pg Cd I-', but >200 pg 1-' of Pb and Zn had no effect on shell growth. Metal concentrations in the lower Tamar are -1 pg Cu 1-l, < 0.5 pg Cd I-', -0 0.5 pg Fe 1-' and -8 pg Zn 1-' (Stebbing et al, 1983).…”

Mussels Mytilus edulis were reciprocally transplanted between 2 environments, the Tamar estuary (south-west England) and Swansea dock (south Wales). Physiological and cellular responses of native and transplanted mussels at each site were measured at the beginning (January, 1978) and after 7, 16 and 23 wk. Tissue concentrations of some metals (Cd, Cu, Fe, Pb, Zn) and hydrocarbons were determined. Changes in metal and hydrocarbon concentrations in the tissues were complex and a function of specific contaminant, tissue and time. There were marked physiological differences between the 2 native populations but transplanted mussels acclimatized to their new environments within 2 mo. This suggested that the measured physiological differences (clearance, respiration and excretion rates, absorption efficiency, 0 : N and scope for growth) were largely determined by environmental rather than genotypic factors.

“…According to Florence & Batley (1980), this is 0.03 ppb. Mytilus edulis is reported to survive and grow at reduced pace in 0.3 ppb (Stromgren 1982). The high concentrations used in the present study were a compromise for the time factor, as the experimental duration was short.…”

“…At a specific site, uptake of a particular contaminant may be affected by a variety of different factors: for example, age, sex, size, tidal position, concentration of other contaminants, physiological state and various environmental variables such as temperature, salinity, particulate load and pH (Bayne & Widdows 1978, Goldberg e t al. 1978, Bayne et al 1979, Simpson 1979, Stromgren 1982. Previously, Clifton et al (1983) described the effects of mussel size, tidal position and seasonal variability of the condition index (C.…”

Rates of uptake of 2 4 1~m , I3'Cs and ' 0 6~u by both the soft tissue and the shell of transplanted Mytilus edulis L. were determined; soft tissue data are compared to theoretically derived values based on the biological half-life and the steady state concentration of these isotopes. The rates of loss of 2 4 1~m , U 9 + 2 4 0~~, 2 3 8~~, I3'Cs and I o 6~u by M. edulis under conditions of stress, manifest as extended periods of shell closure as a consequence of high ambient concentrations of copper and zinc and extended periods of aerial exposure, were examined. Both types of stress did not significantly alter the rate of loss of the Pu isotopes, 13'Cs or I o 6~u from the flesh of the mussel but the 2 4 1~m concentration increased significantly over the depuration period of February to June -a probable consequence of the remobilisation of 2 4 1~m associated with the inner nacreous layer of the shell.
