随着纳米技术的发展和纳米材料的大量开发生产及使用,纳米颗粒排放到环境可能产生的健康和环境风险开始引起广泛的关注,已经成为当前环境领域研究的热点。纳米颗粒的风险不仅来自它们的生物毒性,也与它们在环境中的浓度、形态、迁移转化过程及环境的复杂条件密切相关。自从发现纳米颗粒的生物毒性至今已十年,大量的相关研究工作已经促进了对纳米颗粒风险的了解,但距离全面掌控和准确评价它们的风险尚存在很大的距离。研究瓶颈如缺乏有效的研究技术手段、研究结果的不确定性、研究结果自相矛盾等普遍存在,是当前研究的挑战。本专辑收集了在该研究领域具有影响力的研究人员的最新研究成果和思考,介绍该领域的最新研究进展,希望能帮助读者了解相关研究工作并促进研究人员开展讨论,进一步推进该研究领域和纳米技术的持续发展。
With the development of nanotechnology and the large-scale development, production and use of nanomaterials, the possible health and environmental risks of nanoparticle emission into the environment have drawn wide attention and have become the focus of current research in the field of environment. The risks of nanoparticles derive not only from their biological toxicity but also from their concentration in the environment, morphology, migration and transformation processes and the complex conditions of the environment. Since the biological toxicity of nanoparticles has been discovered for over a decade, a great deal of relevant research has contributed to understanding the risks of nanoparticles, yet there is a long way to go to take full control of and accurately evaluate their risks. Research bottlenecks such as the lack of effective means of research and development, the uncertainty of research results, and the conflicting research results are the common challenges of current research. This album collects the latest research results and thinking of influential researchers in this field, introduces the latest research progress in this field, hoping to help readers understand the relevant research work and promote researchers to discuss and further promote the field of research and The continuous development of nanotechnology.
