Metal(loid) contaminants in food pose a global health concern. This study offers a global analysis of the impact of nanomaterials (NMs) on crop responses to metal(loid) stresses. Our findings reveal that NMs have a positive effect on the biomass production of staple crops (22.8%), while showing inhibitory effects on metal(loid) accumulation in plants (−38.3%) and oxidative damage (−21.6%) under metal(loid) stress conditions. These effects are influenced by various factors such as NM dose, exposure duration, size and composition. Here we introduce a method using interval-valued intuitionistic fuzzy values by integrating the technique for order preference by similarity to an ideal solution and entropy weights to compare the effectiveness of different NM application patterns. These results offer practical insights for the application of NMs in similar multi-criteria decision-making scenarios, contributing to sustainable agriculture and global food safety.

工程纳米材料减少金属 (loid) 积累并增强主食生产,实现可持续农业



食品中的金属污染物对全球健康构成威胁。本研究对纳米材料 (NMs) 对作物对金属 (loid) 胁迫的反应进行了全面分析。我们的研究结果表明,NMs 对主食作物的生物量生产 (22.8%) 有积极影响,同时在金属 (loid) 胁迫条件下对植物中的金属 (loid) 积累 (-38.3%) 和氧化损伤 (-21.6%) 表现出抑制作用。这些影响受各种因素的影响,例如 NM 剂量、暴露持续时间、大小和成分。在这里,我们介绍了一种使用区间值直觉模糊值的方法,该方法通过与理想解的相似性来整合顺序偏好技术和熵权,以比较不同 NM 应用模式的有效性。这些结果为 NMs 在类似的多标准决策情景中的应用提供了实用见解,有助于可持续农业和全球食品安全。
