Over the years, nanoscience and the application of nanomaterials have gained the attention of researchers due to their enormous application history. Especially, the application of AgNPs providing innovative solutions to a wide range of environmental issues, for instance, wastewater treatment, bioremediations, and environmental sensing. Besides all these, the environmental application of silver nanomaterials causes severe problems in the terrestrial and aquatic ecosystems. For their concern, the present study was conducted to expose rainbow trout fish (Oncorhynchus mykiss) to different concentrations of silver nanoparticles for 25 days. In the current study, mortality (LC50), accumulation, and histopathological changes were analyzed. The results have revealed that the silver nanoparticles were mostly accumulated in the liver followed by the intestine, gill, and muscles. The microscopic analysis has shown that the accumulation of silver nanoparticles led to histological changes in gill and intestinal tissues. Necrosis, degeneration, mucus substance on the surface of gill lamella, cell lysis, and gill lamella atrophy were found at (0.04 mg/L) and (0.06 mg/L). The findings in the current study showed less toxicity in the sense of mortality and accumulation of AgNPs. Therefore, further systematic studies are needed to access the influence of silver nanoparticles on the aquatic ecosystem.

虹鳟鱼（Oncorhynchus mykiss）中植物介导的银纳米颗粒毒性的显微分析
多年来，纳米科学和纳米材料的应用因其巨大的应用历史而受到研究人员的关注。特别是，AgNPs 的应用为广泛的环境问题提供了创新的解决方案，例如废水处理、生物修复和环境传感。除此之外，银纳米材料的环境应用给陆地和水生生态系统带来了严重的问题。出于他们的关注，本研究将虹鳟鱼 ( Oncorhynchus mykiss )暴露于不同浓度的银纳米粒子 25 天。在目前的研究中，死亡率 (LC 50)、积累和组织病理学变化进行了分析。结果表明，银纳米颗粒主要在肝脏中积累，其次是肠道、鳃和肌肉。显微分析表明，银纳米颗粒的积累导致鳃和肠组织的组织学变化。在(0.04mg/L)和(0.06mg/L)处发现坏死、变性、鳃片表面粘液物质、细胞溶解和鳃片萎缩。当前研究的结果表明，在 AgNPs 的死亡率和积累意义上，毒性较小。因此，需要进一步的系统研究来了解银纳米粒子对水生生态系统的影响。
