摘　　要：在水生环境中,纳米材料随水体流动而具备迁移性,能增强其环境风险,并影响其环境归趋,研究纳米材料在水生环境中的环境行为尤为必要。同时,纳米材料在水生环境中能够转化,如生物降解和溶解,也会改变其环境浓度和生态毒性。所以,综合考虑纳米材料在水体中的行为和转化,对预测纳米材料的环境归趋和风险评估具有重要现实意义。根据前人实验研究,重点阐述水生环境对纳米材料的影响作用来探讨纳米材料在水体中的行为和转化,并对纳米材料的环境归趋方面的研究进行展望。In the aquatic environment, nanomaterial research play a critical role in influencing environmental behaviors. Since in the flowing water, nanomaterials can be provided with the mobility, therefore enhancing their environmental risks and influencing their environmental tendency. Meanwhile, in the water environment, nano materials can be changed to an- other materials as well as environmental concentration and ecotoxicity. As a result, considering the behaviors and transfor- mation of nanomaterials in water environment, there is an important practical significance in predicting environmental ten- dency and risk assessment. Based on previous experimental studies, we focus on studying the role of aquatic environment impacts of nanomaterials to explore behavior and transformation of nano materials in the water bodies, and make a prospcc- tion of environmental tendency of nanomaterials as well.
