Silver nanoparticles (AgNPs) have gained significant attention in various fields due to their unique properties, but their release into the environment has raised concerns about their environmental and biological impacts. Silver nanoparticles can enter plants following their exposure to roots or via stomata following foliar exposure. Upon penetrating the plant cells, AgNPs interact with cellular components and alter physiological and biochemical processes. One of the key concerns associated with plant exposure to AgNPs is the potential of these materials to induce oxidative stress. Silver nanoparticles can also suppress plant growth and development by disrupting essential plant physiological processes, such as photosynthesis, nutrient uptake, water transport, and hormonal regulation. In crop plants, these disruptions may, in turn, affect the productivity and quality of the harvested components and therefore represent a potential threat to agricultural productivity and ecosystem stability. Understanding the phytotoxic effects of AgNPs is crucial for assessing their environmental implications and guiding the development of safe nanomaterials. By delving into the phytotoxic effects of AgNPs, this review contributes to the existing knowledge regarding their environmental risks and promotes the advancement of sustainable nanotechnological practices.
银纳米粒子（AgNPs）由于其独特的性质，在各个领域引起了广泛关注，但它们释放到环境中引起了人们对其环境和生物影响的关注。银纳米粒子可以在暴露于根部后或通过叶暴露后的气孔进入植物。进入植物细胞后，AgNPs 与细胞成分相互作用并改变生理和生化过程。与植物暴露于 AgNPs 相关的一个关键问题是这些材料诱导氧化应激的潜力。银纳米粒子还可以通过破坏光合作用、养分吸收、水分运输和激素调节等基本植物生理过程来抑制植物的生长和发育。在作物植物中，这些干扰可能会反过来影响收获成分的生产力和质量，因此对农业生产力和生态系统稳定性构成潜在威胁。了解 AgNPs 的植物毒性作用对于评估其环境影响和指导安全纳米材料的开发至关重要。通过深入研究 AgNPs 的植物毒性作用，本综述为其环境风险的现有知识做出了贡献，并促进了可持续纳米技术实践的发展。
