“…If species from a wider geographical range were included, even larger variability could be expected. The estimated elimination rates deviated from the predictions of the caesium elimination model by Rowan & Rasmussen (1995), a model assumed to have high generality (Rowan & Rasmussen 1996), and from the brown trout model of Ugedal et al (1 992). Therefore, the aim of developing one general model for caesium elimination with high enough precision for the whole range of ecotoxicological models or tracer studies may be abandoned.…”

“…However, the variation in caesium elimination shown does not discredit the use of the Rowan & Rasmussen (1995) model in ecotoxicological and tracer studies. For many fish species, this model provides a good approximation of the caesium elimination and can be used to estimate food consumption and fish activity (Rowan & Rasmussen 1996), for example, or in models of caesium turnover. Sensitivity analyses have shown that neither caesium-based estimates of fish activity (Rowan & Rasmussen 1996) nor estimates of fish caesium accumulation (Ugedal, Forseth & Jonsson 1997) are particularly sensitive to variation in caesium elimination estimates, compared with the sensitivity to variation in, for example, assimilation efficiency.…”

“…On the other hand, through the use of caesium-based bioenergetic models (Kevern 1966;Kolehmainen 1974;Hakonson, Gallegos & Whicker 1975;Forseth etal. 1992), caesium has proven to be a useful tracer of food web (Meili 1991) and population dynamics (Forseth, Ugedal & Jonsson 1994;Rowan & Rasmussen 1996). Radioactive caesium has been distributed globally through atmospheric tests of nuclear weapons and the Chernobyl accident, providing good opportunities for the application of caesium as a tracer in ecological studies.…”

“…The model was evaluated by comparisons between model predictions and observations in incomplete data sets (five studies and six additional species) and field estimates of elimination rate (two studies and two additional species). They concluded that the model is applicable to many of the common taxa of north-temperate fish, and in a subsequent study they regard caesium elimination as species-independent and apply their model to species for which laboratory data are not available (Rowan & Rasmussen 1996).…”

Summary1. Ecotoxicological models used to assess the effects of radionuclides on freshwater ecosystems and the potential transfer to humans depend on accurate laboratory estimates of the elimination rate of radionuclides in fish. 2. We determined experimentally the elimination rate (excretion) of caesium (' 34Cs) of Atlantic salmon Salmo salar (two populations), Arctic charr Satuefinus alpinus (two populations), whitefish Coregonus lavaretus and bream Abramis brama by single-dose caesium labelling and measures of subsequent samples of groups of fish maintained at different temperatures. Elimination rates between populations of the same species and among species were compared. 3. Populations of the same species from similar thermal environments had similar elimination rates (Atlantic salmon) whereas those from different thermal environments differed significantly (Arctic charr). 4. Caesium elimination rates varied among fish species. Bream had slower elimination rates than the other species at all temperatures, whereas Atlantic salmon had quicker elimination rates than the others at 16 "C. The remaining differences among species were not consistent across temperatures, indicating differences in thermal performance. 5. Approximately 45% of the estimated elimination rates differed significantly from those predicted by a general caesium elimination model. We conclude that a single model for caesium elimination, valid for a wide range of species and populations, may be difficult to attain.

Abstract-The uptake kinetics of strontium in the common carp (Cyprinus carpio) were characterized in vivo, exposing preacclimated fish to a wide range of Sr 2ϩ (0.27 M-10.0 mM) and Ca 2ϩ (10 M-10 mM) concentrations in water; 85 Sr, 45 Ca, and 47 Ca were used as tracers in determining the uptake, and the possibility of adsorption of the tracers to the exterior of the fish were verified. The uptake rates were determined in the whole body, gills, and blood of the fish after an exposure period of 3 h and were analyzed as a function of the free-ion activity of strontium and calcium in water. With the increase of Sr 2ϩ concentration in the exposure water, Sr 2ϩ uptake did not increase linearly but displayed Michaelis-Menten saturation kinetics, and with the increase of Ca 2ϩ concentration, Sr 2ϩ uptake decreased significantly in the whole body, gills, and blood. The competitive inhibition model fitted to the pooled data for whole-body uptake explains about 94% of the variation in Sr 2ϩ uptake and 71% in Ca 2ϩ uptake, indicating a competitive type of interaction during the transport of these metal ions across the biological interfaces. The maximum uptake rate of Sr 2ϩ (J maxSr ) was estimated to be 243.0 mol/kg/h and that of Ca 2ϩ (J maxCa ) 119.4 mol/kg/h. The apparent K m for Sr 2ϩ uptake increased greatly with the increase of Ca 2ϩ concentration in water (186, 789,and 5,515 M for 35, 348,and 3,480 M Ca 2ϩ , respectively). Estimation of the true K m for Sr 2ϩ uptake (K mSr ) and its inhibitor constant for Ca 2ϩ (K iCa ) yielded the values of 96.3 and 28.5 M, respectively. These values are very close to those obtained for Ca 2ϩ uptake (K mCa ϭ 24.9 and K iSr ϭ 100.9 M). This model provides a mechanistic description of the effect of calcium on strontium uptake from water and, vice versa, in carp.
