Recent advances in nanoscience and nanotechnology have also led to the development of novel nanomaterials, which ultimately increase potential health and environmental hazards. Interest in developing environmentally benign procedures for the synthesis of metallic nanoparticles has been increased. The purpose is to minimize the negative impacts of synthetic procedures, their accompanying chemicals and derivative compounds. The exploitation of different biomaterials for the synthesis of nanoparticles is considered a valuable approach in green nanotechnology. Biological resources such as bacteria, algae fungi and plants have been used for the production of low-cost, energy-efficient, and nontoxic environmental friendly metallic nanoparticles. This review provides an overview of various reports of green synthesised zero valent metallic iron (ZVMI) and iron oxide (Fe₂O₃/Fe₃O₄) nanoparticles (NPs) and highlights their substantial applications in environmental pollution control. This review also summarizes the ecotoxicological impacts of green synthesised iron nanoparticles opposed to non-green synthesised iron nanoparticles.
纳米科学和纳米技术的最新进展也促使了新型纳米材料的开发，这最终增加了潜在的健康和环境危害。人们对开发环境友好型金属纳米颗粒合成方法的兴趣与日俱增。目的是尽量减少合成过程及其附带化学品和衍生化合物的负面影响。利用不同生物材料合成纳米颗粒被认为是绿色纳米技术中的一种有价值的方法。细菌、藻类、真菌和植物等生物资源已被用于生产低成本、高能效且无毒的环境友好型金属纳米颗粒。本综述概述了绿色合成零价金属铁（ZVMI）和氧化铁（Fe₂O₃/Fe₃O₄）纳米颗粒（NPs）的各种报道，并突出了它们在环境污染控制中的重要应用。本综述还总结了绿色合成铁纳米颗粒与非绿色合成铁纳米颗粒相比的生态毒理学影响。
