英文摘要：

Potential environmental and ecological safety problems of manufactured nanomaterials are analyzed,and current research on environmental behaviors of manufactured nanomaterials in natural waters and their toxic effects on aquatic organisms are introduced in this paper.To overcome the shortages of current research,studies should be focused on environmental behaviors and biological effects of manufactured nanomaterials in different hydrodynamic conditions,in order to reveal the impact mechanism of hydrodynamic conditions on environmental behaviors and biological effects of manufactured nanomaterials in flowing waters.The relationships between hydrodynamic conditions,environmental behaviors of manufactured nanomaterials,and toxic effects of manufactured nanomaterials are established to investigate the suitable hydrodynamic conditions for reducing the manufactured nanomaterials＇ bio-toxicity in flowing waters,providing a scientific basis for pollution control of manufactured nanomaterials in rivers and lakes.
