2014年4月17日来源:《环境科学与技术》常常用于定义纳米颗粒的100nm粒度上限可能“不合适”用于评估环境影响,由美国和中国科学家组成的一个研究小组表示。这些科学家在《环境科学与技术》学报上发表的一篇观点文章中写道,100nm的基准“未反映与纳米颗粒的生态学相互作用的复杂性”。有研究报告,超过阙值粒度的纳米颗粒具有不同的物理化学性质。这些发现显示,可能存在产生环境影响的 April 17, 2014 Source: Environmental Science and Technology The 100 nm particle size limit often used to define nanoparticles may be “unsuitable” to assess the environmental impact, a study team consisting of U.S. and Chinese scientists said. In a paper published in the journal Environmental Science and Technology, these scientists wrote that a 100 nm baseline “does not reflect the complexity of the ecological interactions with nanoparticles.” Studies have reported that nanoparticles exceeding the threshold particle size have different physicochemical properties. These findings show that there may be environmental impacts
