本文从重金属对对虾的毒性效应;重金属在对虾体内的积累、分布和排出规律,重金属在对虾体内的致毒和解毒机理等三个方面的研究展开述评。认为重金属对对虾的毒性研究须区分其存在形态及其形式,进行毒性实验的同时亦须重视重金属在对虾体内的生长效应的研究。有关重金属在对虾体内的积累、分布和排出规律的研究较多,但食物链的迁移和生物学放大作用尚未引起足够的注意;重金属在对虾体内的致毒和解毒机制也少见文献报道,尚待深入探讨,并需加强对虾体内不同重金属之间的协同和拮抗机理研究。
This article reviews the toxic effects of heavy metals on shrimp, the accumulation, distribution and discharge of heavy metals in shrimp and the toxicity and detoxification mechanisms of heavy metals in shrimp. It is considered that the study on the toxicity of heavy metals to shrimp should distinguish its existing form and its form. At the same time, it is necessary to pay attention to the study on the growth effect of heavy metals in shrimp. There are many researches on the accumulation, distribution and discharge of heavy metals in shrimp, but food chain migration and biological amplification have not attracted enough attention. The mechanisms of toxic and detoxification of heavy metals in shrimp are rarely reported yet It is necessary to study the synergistic and antagonistic mechanism of different heavy metals in shrimp.
