Abstract

Toxicity of prometryne to early life stages of common carp was assessed. On the basis of accumulated mortality in the experimental groups lowest observed-effect concentration (LOEC) was estimated as 1100 µg/l; and no observed-effect concentration (NOEC) was 850 µg/l. Fulton's condition factor was significantly lower than in controls in fish exposed to 4000 µg/l after 7, 14, and 21 days. By day 14, fish exposed to 4000 µg/l prometryne showed significantly lower mass and total length compared to controls. Fish exposed the 1200 and 4000 µg/l showed delay in development, severe hyperaemia in gill, liver, and caudal and cranial kidney. Subchronic prometryne exposure of early-life stages of common carp at concentrations of 1200 and 4000 µg/l affected their survival, growth rate, early ontogeny, and histology.

摘要

评估了扑草净对鲤鱼幼鱼期的毒性。根据实验组的累积死亡率，估计最低观察效应浓度（LOEC）为1100微克/升；未观察到效应浓度（NOEC）为850微克/升。在暴露于4000微克/升的鱼中，7天、14天和21天后，富尔顿条件系数显著低于对照组。到第14天，暴露于4000微克/升扑草净的鱼与对照组相比，体重和全长显著降低。暴露于1200和4000微克/升的鱼出现发育延迟，鳃、肝脏、尾肾和头肾严重充血。以1200和4000微克/升的浓度对鲤鱼幼鱼期进行亚慢性扑草净暴露，会影响它们的存活、生长速率、早期个体发育和组织学。
