【Abstract】 Nanoscience,information science and life science are the three pillar fields of science in the 21 stcentury.With the rapid development and wide application of nanomaterials,the safety of nanomaterials is attracting worldwide attention. Due to the unique physical and chemical properties of nanomaterials,nanoscale and nanostructured materials can enter the natural environment through a variety of ways,causing toxic effects of organisms and potential effects on human health and the environment. In this paper,the characteristics,emission pathways and possible environmental behaviors of nanomaterials are reviewed. The research results of environmental toxicology of several nanomaterials are described. Finally,the future development direction and important issues to be studied in this new field are prospected.更多还原
