Acute toxic effects of uranium on two aquatic organisms, Zebrafish (Brachydanio rerio) and Ostracod (Cypridopsis vidua)

Abstract

In this paper, we concentrate on the acute toxic effects of uranium on two aquatic organisms, Brachydanio rerio (B. rerio) and Cypridopsis vidua (C. vidua). We found that the toxicity of uranium on C. vidua was significantly greater than that of B. rerio. The results show that C. vidua has a higher sensitivity to uranium, even better than the commonly used test model organisms. In addition to its high sensitivity, C. vidua is a simple and cost-effective toxicological test organism. Therefore, C. vidua is an attractive alternative biological detection material. The acute toxicity results of the test are valuable for establishing water quality standards and protecting human health. At the same time, it enriches the relevant data of uranium on biological toxicity, provides clues for the study of the mechanism of toxicity, and deepens the understanding of the harm of uranium pollution to aquatic ecosystems.
