近年来,纳米技术的快速发展对该行业产生了重大影响。随着纳米技术的广泛应用,纳米粒子不可避免地被释放到环境中,其去向、行为和毒性都是未知的。研究表明,NPs可以被陆生植物吸收、运输和积累。在某些可食用植物中,NPs的存在可能会减少收成并威胁人类健康。了解纳米颗粒在植物体内的传输和毒性是进行风险评估的基础。本文综述了四种类型的纳米颗粒在陆地植物中的运输,以及纳米颗粒对植物生长和细胞结构的影响,以及诱导氧化应激反应和引起遗传毒性损害等潜在机制。希望为今后NPs对植物影响的研究提供参考。
In recent years, the rapid development of nanotechnology has made significant impacts on the industry. With the wide application of nanotechnology, nanoparticles (NPs) are inevitably released into the environment, and their fate, behavior and toxicity are indeterminate. Studies have indicated that NPs can be absorbed, transported and accumulated by terrestrial plants. The presence of NPs in certain edible plants may decrease harvests and threaten human health. Understanding the transport and toxicity of NPs in plants is the basis for risk assessment. In this review, we summarize the transportation of four types of NPs in terrestrial plants, and the phytotoxicity induced by NPs, including their impacts on plant growth and cell structure, and the underlying mechanisms such as inducing oxidative stress response, and causing genotoxic damage. We expect to provide reference for future research on the effects of NPs on plants.
