Abstract

Abstract The monitoring of marine ecosystems is crucial due to the growing threat posed by nuclear power plants and other nuclear anthropogenic emissions. In our work, we used a straightforward and low-cost biomonitoring technique called fluctuation asymmetry (FA) to examine the variation between the left and right sides (developmental instability) of organisms’ traits that were influenced by genetic and environmental variables in the early stages of ontogenesis. The specimens of fish (Leiognathus sp.) and crabs (Portunus sanguinolentus) were collected seasonally and used as bioindicators to determine the effects of Uranium-238 (U-238) radioactivity around a nuclear power plant. The obtained results revealed that FA values were not considered typical values (FA = 0) in all seasons. Moreover, FA values of Leiognathus sp. exhibited insignificant fluctuation for a particular characteristic through the different seasons, while a significant fluctuation occurred amongst the characteristics themselves throughout the same season. Inversely, FA values of the four characteristics in Portunus sanguinolentus displayed seasonal variation amongst them all. Statistically, there was a strong positive correlation (r = 0.5, p < 0.05) between U-238 radioactivity in the flesh of both organisms and the fluctuation asymmetry of different traits but it is not a sign that any radioactive pollution exists.

利用波动不对称性评估铀-238 放射性对印度马德拉斯核电站周围海洋生态系统的影响

摘要由于核电站和其他核人为排放物造成的威胁日益严重，对海洋生态系统的监测至关重要。在我们的工作中，我们使用了一种名为波动不对称（FA）的简单而低成本的生物监测技术，来研究生物在本体形成早期阶段受遗传和环境变量影响的左右两侧性状的变化（发育不稳定性）。研究人员按季节采集了鱼类（Leiognathus sp.）和蟹类（Portunus sanguinolentus）标本，并将其作为生物指标来确定核电站周围铀-238（U-238）放射性的影响。结果显示，FA 值在所有季节都不被视为典型值（FA = 0）。此外，雷公鱼的 FA 值在不同季节对某一特征的波动不明显，而在同一季节，不同特征之间的波动却很大。与此相反，虹鳟的四种特征的 FA 值在不同季节均有变化。从统计学角度看，两种生物肉体中的铀 238 放射性与不同特征的波动不对称性之间存在很强的正相关性（r = 0.5，p < 0.05），但这并不表明存在任何放射性污染。
