摘要
尽管不同纳米材料(<100nm)在污染环境修复研究中的应用越来越受到重视,但纳米技术在给污染环境修复带来重要突破的同时给环境和人类健康带来的风险也值得关注.有研究表明,在污染环境修复研究中,不同的纳米颗粒对生物体的健康会造成一定的危害.目前,在纳米材料的环境修复研究中,针对不同纳米材料的修复效果、修复过程与机理研究较多,而对纳米材料的环境安全性研究才刚刚起步.本文对近年来国内外关于纳米材料环境毒性的研究进行综述,并对该研究领域的前景和重点进行了展望,以期为该领域的深入研究提供借鉴并拓展新的思路.
Though it has been claimed that nanotechnology has great potential in environmental cleaning,caution is required to the application of nano-particles（ 100 nm）.The studies relevant to organism exposure have shown that nano-particles can be hazardous.Currently,more papers are available about the remediation efficiency,characteristics,and mechanisms of manufactured nanoparticles after applied into polluted environment,but few studies are conducted about the ecotoxicological effects of the nano-particles.This paper reviewed the current researches on the hazards of nano-or ultrafine particles in environmental detoxification,discussed the potential environmental risks of applying nano-particles,and prospected the perspectives of the nanoparticles in environmental cleaning research.
