化学污染物对鱼鳔的毒理学研究进展
Review on Toxicology of Chemical Pollutants on Fish Swimbladder
-
摘要: 鱼鳔(swimbladder)是帮助有鳔鱼类完成呼吸、保持流体静力、感觉声音等生理活动的重要功能器官之一。化学污染物暴露能够影响鱼鳔的正常发育或充气,对有鳔鱼类的生存具有潜在威胁。本文首先对鱼鳔功能、形态发育及分子机制进行了介绍。其次对化学污染物导致的鱼鳔发育异常或不充气等毒性效应进行了总结,对特定污染物的潜在作用机制进行了综述。最后对鱼鳔的环境/生态毒理学研究提出展望。Abstract: Swimbladder is one of the most essential organs for the fish with such a gas chamber, and plays a key role in performing respiration, keeping hydrostatics and sensing sound, etc. Exposure to chemical contaminants could affect development and inflation of fish swimbladder, and thus might lead to a potential threat to fish with swimbladder. In this review, firstly, the function, morphological development and molecular mechanisms of fish swimbladder were introduced. Secondly, the reports on abnormal development of swimbladder and its non-inflation caused by exposure to chemical pollutants were summarized, and the potential mechanisms of action were reviewed. Finally, the perspectives on environmental toxicology or ecotoxicology of fish swimbladder were proposed.
