Environmental stresses, including the salt and heavy metals contaminated sites, signify a threat to sustainable crop production. The existence of these stresses has increased in recent years due to human-induced climate change. In view of this, several remediation strategies including nanotechnology have been studied to find more effective approaches for sustaining the environment. Nanoparticles, due to unique physiochemical properties; i.e. high mobility, reactivity, high surface area, and particle morphology, have shown a promising solution to promote sustainable agriculture. Crop plants easily take up nanoparticles, which can penetrate into the cells to play essential roles in growth and metabolic events. In addition, different iron- and carbon-based nanocompositions enhance the removal of metals from the contaminated sites and water; these nanoparticles activate the functional groups that potentially target specific molecules of the metal pollutants to obtain efficient remediation. This review article emphasises the recent advancement in the application of nanotechnology for the remediation of contaminated soils with metal pollutants and mitigating different abiotic stresses. Different implementation barriers are also discussed. Furthermore, we reported the opportunities and research directions to promote sustainable development based on the application of nanotechnology.
环境压力，包括受盐和重金属污染的场地，对可持续作物生产构成威胁。由于人为气候变化，近年来这些压力有所增加。有鉴于此，已经研究了包括纳米技术在内的几种修复策略，以寻找更有效的方法来维持环境。由于独特的物理化学性质，纳米颗粒，即高迁移率、高反应性、高表面积和颗粒形态，已显示出促进可持续农业的有希望的解决方案。农作物植物很容易吸收纳米颗粒，这些纳米颗粒可以穿透细胞，在生长和代谢事件中发挥重要作用。此外，不同的铁基和碳基纳米复合材料增强了从污染场地和水中去除金属的能力；这些纳米颗粒激活了功能基团，这些功能基团可能针对金属污染物的特定分子，从而获得有效的修复。本文综述了纳米技术在修复受金属污染物污染的土壤和减轻各种非生物胁迫方面的最新进展。还讨论了不同的实施障碍。此外，我们根据纳米技术的应用，报告了促进可持续发展的机会和研究方向。
