Chlorfenapyr is a novel class of insecticide-miticide used for crop protection. It poses substantial risks to the reproductive ability of birds as well as environmental stability. This study was focused on the remediation of chlorfenapyr-polluted soil and water through the combined application of green nanotechnology, solubility improving agents and phytoremediation. An analysis using electron microscopy showed that the green synthesis resulted in circular ficus iron nanoparticles (F-Fe0) with diameters of 2.46 nm-11.49 nm, while the ipomoea-silver (Ip-Ag0) and brassica-silver nanoparticles (Br-Ag0) were circular, cubical, hexagonal, triangular and rod -like in shape with sizes ranging from 6.27 to 21.23 nm in IP-Ag0 and from 6.05 to 15.02 nm in Br-Ag0. After 24 h of treatment with F-Fe0, Ip-Ag0 and Br-Ag0 supported on activated charcoal (Ach), the chlorfenapyr in the aqueous solution was reduced to 86%, 79.70%, and 79.70%, respectively, compared to the 6.16% in aqueous solution. Moreover, after 24 h of treatment with Plantago major plus F-Fe0Ach, P. major plus Ip-Ag0Ach, and P. major plus Br-Ag0Ach, the chlorfenapyr in the aqueous solution was reduced to 93.7%, 91.30%, and 92.92%, respectively, as compared to the 69.27% in P. major. After four days of exposure, the percentage of chlorfenapyr degradation in the soil (i.e. control) only reached 12.40%,while the degradation rates were enhanced by 71.22%, 57.32% and 73.10%, respectively, in the presence of P. major plus nanoparticles (F-Fe0, Ip-Ag0 and Br-Ag0). The integration of green nanotechnology, solubility-improving agents, and phytoremediation by Plantago major has played a major role in the remediation of soil and water contaminated with chlorfenapyr.

绿色纳米植物修复和溶解度改进剂，用于修复氯苯那吡污染的土壤和水。
氯苯那吡是一类新颖的杀虫剂-杀螨剂，用于作物保护。它对鸟类的繁殖能力以及环境稳定性构成重大风险。这项研究的重点是通过绿色纳米技术，溶解度改善剂和植物修复剂的联合应用来修复被氯芬那吡污染的土壤和水。电子显微镜分析表明，绿色合成产生了直径为2.46 nm-11.49 nm的圆形榕铁纳米颗粒（F-Fe0），而亚油银-银（Ip-Ag0）和芸苔-银纳米颗粒（Br-Ag0）呈圆形，立方，六边形，三角形和棒状，其大小在IP-Ag0中为6.27至21.23 nm，在Br-Ag0中为6.05至15.02 nm。在活性炭（Ach）上负载F-Fe0，Ip-Ag0和Br-Ag0 24小时后，与水溶液中的6.16％相比，水溶液中的氯芬那比分别降低至86％，79.70％和79.70％。此外，用车前大花加F-Fe0Ach，大花加Ip-Ag0Ach和大花加Br-Ag0Ach处理24小时后，水溶液中的氯芬那比减少至93.7％，91.30％和92.92％分别为P. major的69.27％。暴露四天后，在存在P.major plus纳米粒子的情况下，土壤（即对照）中的氯芬那吡降解百分比仅达到12.40％，而降解率分别提高了71.22％，57.32％和73.10％。 （F-Fe0，Ip-Ag0和Br-Ag0）。绿色纳米技术，溶解度改善剂，
