Foliar application of beneficial nanoparticles exhibits potential in mitigating combined stresses from heavy metals and polycyclic aromatic hydrocarbons (PAHs) crops, necessitating a comprehensive understanding plant–rhizosphere–microbial processes to promote sustainable nanotechnology agriculture. Herein, we investigated the mechanisms foliar zinc oxide (nZnO) on lettuce growth under phenanthrene (Phe) cadmium (Cd) costress. Compared Phe + Cd treatment, low (L-nZnO) high (H-nZnO) concentration nZnO increased fresh biomass (27.2% 8.42%) root length (20.4% 39.6%) decreased MDA (35.0% 40.0%) H2O2 (29.0% 15.6%) levels. L-nZnO H-nZnO roots (26.8% 41.8%) enhanced Zn (19.9% 107%), stems (221% 2510%), leaves (233% 1500%), suggesting long-distance migration subsequently regulating metabolic pathways microbial communities. Metabolomics revealed that modulated leaf glycerophospholipid metabolism amino acid promoted rhizosphere soil carbon phosphorus metabolism. Additionally, enriched plant-growth-promoting, extreme, stress-resistant bacteria heavy-metal-resistant PAH-degrading soil. These findings underscore promising nanostrategy benefit plant cocontaminated with PAHs.
