重金属离子对中国林蛙蝌蚪的毒性效应研究进展

Toxic Effects of Heavy Metals Ions on Rana chensinensis Tadpoles

摘要: 蝌蚪作为中国林蛙的幼体，对水环境有着极强的依赖性。水环境中的可溶性重金属离子可以通过中国林蛙蝌蚪的呼吸系统和皮肤进入体内，影响蝌蚪的存活状况、生长发育和生理生化指标，因此可以用来监测水体环境的变化。本文从Cu²⁺、Pb²⁺、Cd²⁺、Cr⁶⁺和Hg²⁺等重金属离子对中国林蛙蝌蚪的毒性效应方面进行综述，为中国林蛙蝌蚪的生态保护和水环境监测提供科学依据。

Abstract: As a larva of Rana chensinensis, tadpoles are highly dependent on water environment. Soluble heavy metal ions in the water environment can enter the body through the tadpole’s respiratory system and skin, affecting the survival, growth and physiological and biochemical indicators of tadpoles, so they can be used to monitor the changes of water environment. The toxic effects of heavy metal ions such as Cu²⁺, Pb²⁺, Cd²⁺, Cr⁶⁺ and Hg²⁺ on Rana chensinensis tadpoles were reviewed in this paper, which provided scientific basis for ecological protection and water environment monitoring of Rana chensinensis tadpoles.
