摘要
纳米颗粒因其独特的物理化学性质被广泛应用于生产和生活中,随着纳米颗粒使用的迅速增长,大量纳米颗粒进入环境中,其潜在的风险受到众多研究者的高度关注。在环境中,具有特殊功能的微生物扮演着举足轻重的作用。通过调研纳米颗粒对功能型微生物毒性的最新研究成果,从生物个体角度综述了纳米颗粒对功能型微生物的毒性效应及相应的致毒机制,着重从微生物群体角度论述了纳米颗粒对功能型微生物群体的影响,同时还探讨了削减纳米颗粒毒性的途径。最后进一步分析了目前纳米生态毒性研究中的问题,并对今后研究的方向进行了展望。
Nanoparticles have been widely used in the production and life due to its unique physi-cochemical properties. As the rapid growth of the use of nanoparticles, a large number of nanoparticles have been released into the environment. Researchers are paying more attention to the potential risk of nanoparticles. Functional microorganisms play an important role in various ecosystems. With investigation of huge amount of related scientific research references, nanotoxicity studies were reviewed in regard to the functional microorganism toxicity effect and mechanism from the perspective of individual microorganism. Moreover, the effects of nanoparticles on the functional microorganisms were emphatically elaborated from the perspective of microbial groups. Approaches to reduce the toxicity of nanoparticles were also discussed. The current problems of nanotoxicity studies were analyzed, and the future directions of research were suggested
