摘　　要：纳米零价铁(nanoscale zero-valent iron,NZVI)是一种新型的地下水修复材料,NZVI的生物安全性研究已经引起了世界各国学者的广泛关注。本文综述了国内外有关NZVI微生物毒性的研究成果,重点介绍了NZVI对微生物的毒性效应及致毒机理,归纳总结了影响NZVI颗粒毒性效应的各种因素,并对未来NZVI材料毒性研究的发展方向进行了展望,以期为NZVI的生物安全性研究提供参考。Nanoscale zero-valent iron （NZVI） as a kind of emerging remedial material is used for contaminated groundwater. Its biological safety has received great concerns in recent years. In the study, the previous research re-sults on the microbial toxicity of NZVI were summarized. The effect and mechanism of microbial toxicity of NZVI was discussed and analyzed, and major factors influencing the toxicity of NZVI nanoparticle were illuminated. The research prospect on the toxicity of NZVI nanoparticle was put forward so as to provide theoretical support for the research work on biological safety of NZVI.
