The marine-estuarine polychaete Capitella is an indicator of organic pollution and plays important roles in sewage waste cycling. The antidepressant fluoxetine can be accumulated in streams and sewage effluents and it could pose a hazard to infauna. Effects of fluoxetine on feeding and growth of Capitella teleta were investigated through the exposure to 0, 0.001, 0.03, 0.3 and 3.3 μg/g dry weight sediment-spiked fluoxetine during 18 days. No effects of fluoxetine concentrations were observed on egestion rates, body weight and size-specific egestion rates. Fluoxetine favoured the occurrence of males with abnormal genital spines. This suggests that fluoxetine can have important reproductive implications. Further studies are recommended to assess potential detrimental effects on benthic infauna inhabiting close to sewage treatment plants.
海洋-河口多毛纲环节动物沙蚕是有机污染的指示剂，在污水废物循环中发挥着重要作用。抗抑郁药氟西汀可在溪流和污水中积累，对底栖无脊椎动物构成危害。通过在 18 天内暴露于 0、0.001、0.03、0.3 和 3.3μg/g 干重沉积物中添加氟西汀，研究了氟西汀对沙蚕生长和摄食的影响。氟西汀浓度对排粪率、体重和特定身体大小的排粪率没有影响。氟西汀有利于出现生殖器棘异常的雄性。这表明氟西汀可能对生殖有重要影响。建议进一步研究评估对靠近污水处理厂的底栖无脊椎动物的潜在有害影响。
