Accumulation and depuration kinetics in the samples of mussel (Mytilus galloprovincialis L. 1758) and sea snail (Rapana venosa (Valenciennes, 1846)) exposed to ¹³⁷Cs radioisotope via seawater exposure were investigated under laboratory conditions. Accumulation and depuration kinetics were monitored for 49 and 59 days, respectively. Concentration factor and biological half-life values were calculated from the accumulation and depuration kinetics of mussel and sea snail samples. Concentration factors at equilibrium were 16.25 ± 4.41 and 19.50 ± 1.17 for large and small mussels, respectively, while 16.34 ± 0.70 and 14.31 ± 0.63 for large and small snails, respectively. The biological half-lives at slow components were 38.50 and 77.00 days for large and small mussels, respectively, while 49.50 and 57.75 days for large and small snails, respectively. Compared to the literature, the slightly higher concentration factor and biological half-life values obtained in this study for both mussel and snail samples may help to identify these species as bio-indicators of the ¹³⁷Cs radioisotope in the marine environment. In addition, it was statistically determined that body size is an important parameter for both living organisms in bioaccumulation experiments unlike the depuration experiments. In the light of all these results, it has been determined that mussel and sea snail organisms are extremely valuable indicators in terms of reflecting radioactive pollution in the sea in monitoring the ¹³⁷Cs radioisotope for possible inputs of any radioactive pollution in the marine environment.

贻贝 ( Mytilus galloprovincialis L. 1758) 和海蜗牛 ( Rapana venosa (Valenciennes, 1846))样品中的积累和净化动力学暴露于¹³⁷在实验室条件下研究了通过海水暴露的 Cs 放射性同位素。分别监测了 49 天和 59 天的积累和净化动力学。根据贻贝和海螺样品的积累和净化动力学计算浓度因子和生物半衰期值。平衡时大和小贻贝的浓度因子分别为 16.25±4.41 和 19.50±1.17，而大蜗牛和小蜗牛分别为 16.34±0.70 和 14.31±0.63。大和小贻贝的慢组分生物半衰期分别为 38.50 天和 77.00 天，而大蜗牛和小蜗牛分别为 49.50 和 57.75 天。与文学作品相比，海洋环境中的¹³⁷ Cs 放射性同位素。此外，与净化实验不同，从统计学上确定，在生物积累实验中，体型是两种生物体的重要参数。根据所有这些结果，已确定贻贝和海螺生物是反映海洋中放射性污染的极其有价值的指标，用于监测¹³⁷ Cs 放射性同位素以了解海洋环境中任何放射性污染的可能输入。
