| 英文摘要 | The extensive use of nano-fabricated products in daily life is releasing a large volume of engineered nanoparticles (ENPs) in the environment having unknown consequences. Meanwhile, little efforts have been paid to immobilize and prevent the entry of these emerging contaminants in the food chain through plant uptake. Herein, we investigated the biochar role in cerium oxide nanoparticles (CeO(2)NPs) bioaccumulation and subsequent translocation in wheat (Triticum aestivurn L.) as well as impact on growth, photosynthesis and gasexchange related physiological parameters. Results indicated that CeO(2)NPs up to 500 mg L-1 level promoted the plant growth by triggering photosynthesis, transpiration and stomatal conductance. Higher NPs concentration (2000 mg CeO(2)NPs L-1) has negatively affected the plant growth and photosynthesis related processes. Conversely, biochar amendment with CeO(2)NPs considerably reduced (-9 folds) the plants accumulated contents of Ce even at 2000 mg L-1 exposure level of CeO(2)NPs through surface complexation process and alleviated the phyto-toxic effects of NPs on plant growth. XPS and FTIR analysis confirmed the role of biochar-mediated carboxylate and hydroxyl groups bonding with CeO(2)NPs. These findings provides an inside mechanistic understanding about biochar interaction with nano-pollutants to inhibit their bioavailability to plant body. |
