| Abstract: | Three kinds of fish from a natural fishpond in the north of Taiwan were collected and analyzed in this study. The three species were non-predatory Ctenopharyn odon idellus, predatory Aristichthys nobilis and predatory Mylopharyngodon piceus. The activity concentrations of 90Sr in bone and edible flesh of fish, as well as in water and soil of fishpond were measured by using the radiochemical analysis. Additionally, the concentration of stable calcium in fish bone, Ca]bone, and that of stable strontium in fish bone, Sr]bone, were measured by ICP-AES. From the results, the concentration factors of 90Sr, CF(90Sr), in fish bone was no statistic difference between non-predatory and predatory fish. Besides, the accumulation of 90Sr in the non-predatory fish remarkably decreased with increasing the fish weight. As for the predatory fish, they both showed no statistically significant correlations between the 90Sr activity concentration and the fish weight. Regarding the activity concentrations of 90Sr in fish bone, all the fish were observed positively correlated with the measured Sr]bone. |
