英文摘要	Agricultural soil is gradually becoming a primary sink for metal -based nanoparticles (MNPs). The uptake and accumulation of MNPs by crops may contaminate food chain and pose unexpected risks for human health. Here, we investigated the fate and transformation of CuO nano particles (NPs) in the soil -rice system during the rice lifecycle. The results show that at the maturation stage, 1000 mg/kg CuO NPs significantly decreased redox potential by 202.75 triV but enhanced electrical conductivity by 497.07 mS/cm compared to controls. Moreover, the bioavailability of highest CuO NPs in the soil was reduced by 69.84% along with the plant growth but then was significantly increased' y 165% after drying -wetting cycles. Meanwhile, CuO and Cu coMbined with humic acid were transformed to Cu2S and Cu associated with goethite by X-ray absorption near edge structure analysis. AdditiOnally, CuO NPs had an acute negative effect on the plant growth than bulk particles, which dramatically reduced the fresh weight of grains to 6.51% of controls. Notably, CuO NPs were found to be translocated from soil to plant especially to the chaff and promoted the Cu accumulation in the aleurone layer of rice using micro X-ray fluorescence technique, but could not reach the polished rice.
