The juvenile fishes of 革胡子鲇(mean Length: 12.3 ± 3.5 cm; mean weight: 18.52 ± 6.41 g) were used for the acute and chronic toxicity tests. They were exposed to 7 mg/L each of the bulk and nano sizes of the three metallic oxides either singly or in mixtures for 28 days. The basis for the sublethal concentration was that the 96 hr acute toxicity of the varied sizes of the three metallic oxides was nontoxic up to the concentrations of 100 mg/L with no significant mortality at the highest exposure concentrations. The gills were collected for histopathology. 结果。三个金属氧化物纳米颗粒的的SiO是最有毒的,与组织病理学改变指数为20.0(HAI),随后通过纳米的CuO(HAI,10.0)和纳米的Al2Ø3(HAI,2.0)。在单次曝光中,鳃改变包括鳃薄片(EGL),肥大(HPT),水肿(OD),和坏死(N)的侵蚀的高频率。Less damage was observed at the combination of the metal oxide nanoparticles of SiO + Al2Ø3,SiO + CuO and SiO + Al2Ø3 + CuO in equal (1 : 1—HAI, 2 and 6; 1 : 1 : 1—HAI, 6) and unequal ratios (1 : 2—HAI, 16 and 6; 2 : 1—HAI, 8 and 6). Similarly, all bulk combinations were also antagonistic except for the equal ratio of bulk CuO (HAI, 20) and bulk Al2Ø3(HAI,10),其产生具有32 HAI加性效应。 结论。纳米氧化铝的联合行动2Ø3和CuO与二氧化硅产生了低的毒性作用,不像他们单个试验的高毒性;这也表明,纳米氧化铝2Ø3和CuO是拮抗剂。类似地,本体金属氧化物中(SIO,铝2Ø3和CuO),氧化铜是最有毒的。散装二氧化硅和Al2Ø3是对CuO对鱼鳃的影响拮抗。有必要正确记录纳米颗粒的生态影响在水生环境。SN - 1687-9503 UR - https://doi.org/10.1155/2019/7686597 DO - 10.1155 /七百六十八万六千五百九十七分之二千○一十九JF - 中华纳米技术的PB - Hindawi出版KW - ER -
