Abstract: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 results 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.
