| 摘 要： | 为系统评价纳米二氧化钛(nTiO2)对水生生物的安全性,研究其对斜生栅列藻(Scenedesmus obliquus)、大型溞(Daphnia magna Straus)、斑马鱼(Brachydanio rerio),以及非洲爪蟾(Xenopus laevis)蝌蚪的急性毒性,并进行安全评价。结果表明,nTiO2对斜生栅列藻、大型溞、斑马鱼和非洲爪蟾蝌蚪的急性毒性分别为0.140 mg·L-1(72 h-EC50)、1.26 mg·L-1(48 h-EC50)、22.0 mg·L-1(96 h-LC50)和5.02 mg·L-1(96 h-LC50),毒性级别分别为高毒、中毒、低毒和中毒。

| Abstract: | In order to assess the safety of nano-TiO2 (nTiO2) to aquatic organisms systematically, its acute toxicity to Scenedesmus obliquus, Daphnia magna Straus, Brachydanio rerio and Xenopus laevis tadpoles was studied, and its safety was evaluated. The results showed that the acute toxicities of nTiO2 to Scenedesmus obliquus, Daphnia magna Straus, Brachydanio rerio and Xenopus laevis tadpoles were 0.140 mg·L-1 (72 h-EC50)、1.26 mg·L-1 (48 h-EC50)、22.0 mg·L-1 (96 h-LC50) and 5.02 mg·L-1 (96 h-LC50), respectively, and their toxictiy levels were high toxicity, moderate toxicity, low toxicity and moderate toxicity, respectively. |
