为了评估纳米农药（NPs）相对于常规农药的环境影响，我们选择CuO NPs和常规CuSO4作为番茄病害防治的案例研究，并使用生命周期评估（LCA）来评估其环境影响。从Ecoinvent数据库和实验室实验获得的数据（即，氧化铜纳米颗粒的合成和表征）通过理论放大框架进行处理，以确定工业生产规模下的附带环境影响。基于质量（每单位质量）和抗微生物性能（每单位功效）比较结果，表明CuO NP表现出比常规CuSO 4超过10倍的效率改进。与传统CuSO4农药相比，单位药效下CuO纳米颗粒在可再生能源（降低64.7%）、人类健康（降低69.6%）、生态系统质量（降低53.2%）和整体环境绩效（降低67.8%）方面具有明显优势。此外，发现乙醇、乙烯和铜阳极是生产CuO NP过程中对环境影响的重要贡献者。我们的工作提供了纳米和常规农药之间的全面比较评估，揭示了纳米农药的环境潜力，并有助于农业生产力和环境可持续性。
To evaluate the environmental implications of nanopesticides (NPs) relative to conventional pesticides, we selected CuO NPs and conventional CuSO4for tomato disease control as a case study and used life cycle assessment (LCA) to evaluate their environmental impacts. Data obtained from the Ecoinvent database and laboratory experiments (i.e., synthesis and characterization of CuO NPs) were processed by a theoretical scale-up framework to determine the collateral environmental impacts at an industrial production scale. The results were compared on the basis of mass (per unit mass) and antimicrobial performance (per unit efficacy), showing that CuO NPs exhibited over a 10-fold efficiency improvement than conventional CuSO4. Particularly, CuO NPs had obvious advantages in renewable energy (reduced 64.7%), human health (reduced 69.6%), ecosystem quality (reduced 53.2%), and overall environmental performance (reduced 67.8%) under per unit efficacy, compared to conventional CuSO4pesticides. Additionally, ethanol, ethylene, and copper anode were found to be significant contributors to environmental impacts in the process of producing CuO NPs. Our work provides a holistic comparative assessment between nano- and conventional pesticides, which sheds light on the promising environmental potential of nanopesticides and contributes to agricultural productivity and environmental sustainability.
