摘要:进入农田土壤的人工纳米颗粒对土壤中重金属迁移转化及毒性的影响仍不明确。通过模拟稻田淹水-落干过程，研究了二氧化钛（TiO2-NPs）、氧化锌（ZnO-NPs）和多壁碳纳米管（MWCNTs）3种典型人工纳米颗粒对水稻土中重金属Cd赋存形态及生物有效性的影响。结果表明，3种纳米颗粒的添加均引起了土壤pH的增加；TiO2-NPs和ZnO-NPs添加能够显著降低土壤中酸可提取态Cd含量；ZnO-NPs的添加对土壤中铁锰氧化物结合态和有机结合态Cd的含量也有明显降低，但不同浓度处理间Cd含量并无显著差异；MWCNTs对土壤Cd形态转化无显著影响。与对照处理相比，添加TiO2-NPs的处理土壤中，CaCl2和DTPA提取态Cd含量分别降低了13.9%~17.5%和5.4%~8.9%，降幅均与TiO2-NPs添加浓度成正比。添加ZnO-NPs的土壤中，DTPA提取态Cd的含量降幅在8.4%~18.7%之间，降低幅度与ZnO-NPs添加浓度成反比。

Abstract:The impacts of engineered nanoparticles (ENPs) on heavy metal transformation and biotoxicity in farmland soil are mostly unknown. A flooding-drying simulation experiment was conducted to study the effects of three typical engineered nanoparticles (TiO2-NPs, ZnO-NPs and multi-walled carbon nanotubes ) on Cd chemical speciation and bioavailability in paddy soil. Results showed that the addition of three nanoparticles caused the increase of soil pH value. The addition of TiO2-NPs and ZnO-NPs significantly reduced the acid-soluble fraction Cd concentration in soil. The addition of ZnO-NPs also significantly reduced the Fe/Mn oxides bound fraction and organic bound Cd concentration in soil, but there was no significant difference in Cd concentration among different dose treatments. MWCNTs had no significant effect on soil Cd chemical speciation transformation. With TiO2-NPs addition, CaCl2 and DTPA extracted Cd concentration decreased in range from 13.9% to 17.5% and 5.4% to 8.9%, respectively compared with the control, and the decrease was directly proportional to TiO2-NPs dosage. In the soil with ZnO-NPs addition, the DTPA extracted Cd concentration decreased in range from 8.4% to 18.7%, and the decrease was inversely proportional to ZnO-NPs dosage.
