A review and test of predictive models for the bioaccumulation of radiostrontium in fish.
Empirical relations between the (90)Sr concentration factor (CF) and the calcium concentration in freshwater aquatic systems have previously been determined in studies based on data obtained prior to the Chernobyl accident. The purpose of the present research is to review and compare these models, and to test them against a database of post-Chernobyl measurements from rivers and lakes in Ukraine, Russia, Belarus and Finland. It was found that two independently developed models, based on pre-Chernobyl empirical data, are in close agreement with each other, and with empirical data. Testing of both models against new data obtained after the Chernobyl accident confirms the models' predictive ability. An investigation of the influence of fish size on (90)Sr accumulation showed no significant relationship, though the data set was somewhat limited.
