To investigate the interaction of zinc oxide nanoparticles (ZnO NPs) with fly ash soil (FAS) for the reduction of metals from FAS by were studied. The average accumulation of metals by stem were Fe 79.6%; Zn 88.5%; Cu 67.5%; Pb 93.6%; Ni 43.5% and Hg 39.4% at 5.5 g ZnO NP. The concentration of ZnO NP at 1.5 g did not affect the metals accumulation, however at 5.5 g ZnO NP showed highest metal reduction was 96.7% and at 10.5-15.5 g ZnO NP of 19.8%. The metal reduction rate was for Fe 16.4; Zn 21.1; Pb 41.9; Hg 19.1 was higher than Ni 6.4 and Cu 11.3 from the FAS at 5.5 g ZnO NP whereas, the reduction rate of Pb showed highest. With doses of 5.5 g ZnO NP the biomass increased upto 78%; the metal reduced upto 98.7% with the share of 100% ZnO NP from FAS. Further investigation with phytotoxicity the plant reactive oxygen species (ROS) production were affected due was mainly due to the recovery of metals from FAS ().
研究了氧化锌纳米颗粒（ZnO NPs）与粉煤灰土壤（FAS）的相互作用，以通过 降低FAS中的金属含量。在5.5 g ZnO NP时， 茎对金属的平均积累量分别为：铁79.6%；锌88.5%；铜67.5%；铅93.6%；镍43.5%；汞39.4%。1.5 g的ZnO NP浓度不影响金属积累，但5.5 g ZnO NP时金属还原率最高，为96.7%，10.5 - 15.5 g ZnO NP时为19.8%。在5.5 g ZnO NP时，FAS中金属的还原率为：铁16.4；锌21.1；铅41.9；汞19.1，高于镍6.4和铜11.3，其中铅的还原率最高。在5.5 g ZnO NP剂量下，生物量增加高达78%；金属还原高达98.7%，其中100%来自FAS的ZnO NP。进一步对植物毒性进行研究，植物活性氧（ROS）的产生受到影响，这主要是由于从FAS中回收了金属（）。
