In recent years, copper-based nanomaterials (Cu-based NMs) have shown great potential in promoting agriculture development due to their special physicochemical characteristics. With the mass production and overuse of Cu-based NMs, there are potential effects on the soil-plant environment. Soil organisms, especially soil microorganisms, play a significant part in terrestrial or soil ecosystems; plants, as indirect organisms with soil-related Cu-based NMs, may affect human health through plant agricultural products. Understanding the accumulation and transformation of Cu-based NMs in soil-plant systems, as well as their ecotoxicological effects and potential mechanisms, is a prerequisite for the scientific assessment of environmental risks and safe application. Therefore, based on the current literature, this review: (i) introduces the accumulation and transformation behaviors of Cu-based NMs in soil and plant systems; (ii) focuses on the ecotoxicological effects of Cu-based NMs on a variety of organisms (microorganisms, invertebrates, and plants); (iii) reveals their corresponding toxicity mechanisms. It appears from studies hitherto made that both Cu-based NMs and released Cu may be the main reasons for toxicity. When Cu-based NMs enter the soil-plant environment, their intrinsic physicochemical properties, along with various environmental factors, could also affect their transport, transformation, and biotoxicity. Therefore, we should push for intensifying the multi-approach research that focuses on the behaviors of Cu-based NMs in terrestrial exposure environments, and mitigates their toxicity to ensure the promotion of Cu-based NMs.
近年来，铜基纳米材料（Cu-based NMs）因其特殊的物理化学特性，在促进农业发展方面显示出巨大的潜力。随着 Cu-based NMs 的大规模生产和过度使用，它们可能对土壤-植物环境产生潜在影响。土壤生物，特别是土壤微生物，在陆地或土壤生态系统中起着重要作用；而植物作为与土壤相关的 Cu-based NMs 的间接生物，可能会通过植物农产品影响人类健康。了解 Cu-based NMs 在土壤-植物系统中的积累和转化，以及它们的生态毒理学效应和潜在机制，是科学评估环境风险和安全应用的前提。因此，基于目前的文献，本综述：（i）介绍了 Cu-based NMs 在土壤和植物系统中的积累和转化行为；（ii）重点关注 Cu-based NMs 对各种生物（微生物、无脊椎动物和植物）的生态毒理学效应；（iii）揭示了它们相应的毒性机制。迄今为止的研究表明，Cu-based NMs 和释放的 Cu 可能是毒性的主要原因。当 Cu-based NMs 进入土壤-植物环境时，其内在的物理化学性质以及各种环境因素也会影响它们的迁移、转化和生物毒性。因此，我们应该加强多途径研究，重点关注 Cu-based NMs 在陆地暴露环境中的行为，并减轻其毒性，以确保 Cu-based NMs 的推广。
