| contents | Ecotoxicological impacts of short-term fluoxetine exposure on the intertidal sea urchin (Heliocidaris crassispina): Effects on anti-predation, feeding/digestion, and reproduction. Xu, Xiuwen Jin, Xiuqi Ding, Keying Casini, Giovanni Jia, Jinyue Wang, Zexianghua Yin, Xiaolong Yang, Jingwen Wang, Jixiu Wang, Tianming Fluoxetine (FLX), a commonly prescribed antidepressant, has entered aquatic envi ronments due to its widespread use and the inefficiency of wastewater treatment plants in fully removing it. This has led to growing concerns within the scientific community about its potential adaptive effects on marine organisms, particularly in intertidal zones where research is still limited. To address these concerns, this study investigated the short-term adaptive effects of FLX at varying concentrations (0.3, 3, 30 μg/L) on the intertidal sea urchin Heliocidaris crassispina, a species critical to the intertidal ecosystem. The data reveal that there was a dose-dependent increase in the sea urchins' reaction time to environmental threats. Despite the absence of a substantial alteration in the overall food consumption, the foraging time of the three groups of sea urchins exposed to varying degrees of FLX exhibited an increase, while the food consumption demonstrated a decrease, and the activities of pepsin and lipase in the intestine exhibited an increase. Additionally, FLX interfered with the normal gonadal development cycle and induced higher rates of anomaly and asymmetry in offspring. These findings indicate that short-term exposure to FLX may have adverse effects on the anti-predation, feeding and reproduction of sea urchins, providing a novel insight into the ecological impact of antidepressant pollution in intertidal ecosystems. |
