摘　　要：纳米银是使用最为广泛的一种纳米材料,纳米银过度使用对水环境安全构成了一定的威胁。通过查阅国内外资料,阐明了纳米银在水环境中的行为及归宿,概述了纳米银在水环境中的污染水平、生物累积及纳米银对水生生物的影响。最后,对纳米银的毒理学研究方向和纳米银的去除问题进行了展望。Nanomaterials have already been widely used in a range of industrial, commercial, and medical products as the novel and size-related physicochemical properties. Silver nanoparticles rank first among the most prevalent nanomaterials in consumer products. The widespread use of silver nanoparticles may leads to the risk of environment pollution. This review mainly introduced the synthesis of silver nanoparticles, described the behavior and fate of silver nanoparticles in the aquatic environment, and summarized the pollution level and bioaccumulation of silver nanoparticles in aquatic organisms and the effect of silver nanoparticles on aquatic organisms. The toxicology study and remove of silver nanoparticles were also put forward.
