In recent years, nanotechnology has been developing continuously. Due to their advantageous huge specific surface areas, microinterface characteristics, remediation ability and potential environmental risks, nanomaterials have become a hot topic in the field of environmental research. With the mass production and use of nanomaterials, they will inevitably be discharged or leaked into the water environment. In this paper, we will describe some typical nanomaterials, such as nanoscale zero valent iron (nZVI), graphene nanomaterials (GNMs), TiO 2 nanoparticles (NPs), ZnO NPs, Fe 3 O 4 NPs, carbon nanotubes (CNTs), Ag NPs, and other nanomaterials in water environments, focusing on the positive and negative effects of some nanomaterials in water environments. The remediation function and the impact of nanomaterials in water environments, including behavior of nanomaterials and their toxicity to aquatic organisms will be discussed. This will be of great significance for our subsequent research on nanomaterials. • The behavior of nanomaterials in the water environment (lakes, rivers, oceans and wetlands) was summarized. • The remediation effects and mechanisms of nanomaterials for the water environmental problems were reviewed. • Some nanomaterials can produce toxic effects on planktons and mocrobes in the water environment.
