| 摘 要： | 重金属是一类非降解且富集性较强的常见水体污染物,被鱼类摄取后可在脑组织、肾脏和肝脏等器官中富集,并对鱼类产生分子、生理生化等毒性作用,影响其生长发育、繁殖和代谢,甚至引起死亡。文章从重金属进入鱼体内的途径、重金属在鱼体内的富集情况、重金属对鱼类的毒性作用及其作用机制等方面综述了重金属胁迫对鱼类的影响,并提出今后应加强重金属胁迫对鱼类毒害作用机制的系统深入研究,探讨不同重金属对鱼类的联合毒性作用方式,确定重金属暴露浓度与响应指标间的剂量—效应关系及其影响因素,研究重金属胁迫下鱼类氧化胁迫发生的信号调控机制,同时加强环境重金属污染的早期预警生物标志物研究,将重金属对鱼类毒性的研究与水质监测及在线预警相结合,进行预警鱼类的筛选与驯化及鱼类生物学灵敏性信号指标选择等,为渔业环境监测及鱼类健康养殖提供科学依据。

| Abstract: | Heavy mental is a kind of non-degradable, highly enriched common water pollutants, which can be accu-mulated in brain, kidney and liver, and other organs of fish. It can produce molecular and physiological and biochemical toxicity to fish, which affects the growth, reproduction and metabolism of fish, and even causes death. The present paper reviewed the influence of heavy metals on fish, from several aspects including heavy metals entering body of the fish, ac-cumulation of heavy metals in fish, acute toxicity of heavy metals to fish and toxicity mechanism of heavy metal to fish. It emphasized that the systematic study on toxicity mechanism of heavy metals in fish should be strengthened in the future. The joint toxicity effect of different kinds of heavy metals on fish was investigated to confirm the influential factors and the dose -effect relationship between exposure concentration of heavy metals and response index. The signal transduction mechanism of oxidative stress of fish under heavy metal stress was also studied. In addition, the study on early warning biomarkers of environmental heavy metal pollution also should be strengthened, and the research of heavy metal toxicity to fish should be combined with online water quality monitoring and early warning, it also needs to screen and domesticate the warning fish and to select fish biology signal sensitivity index, which can provide a scientific basis for fishery environ-ment monitoring and healthy fish breeding. |
