With the fast development of nanotechnology, reactive engineered nanomaterials (ENMs) are increasingly discharged into the environment, where they interact with environmental components and organisms and thus pose potential risks. The interactions‐derived formation of nano‐environmental and nano‐bio interfaces determines environmental behaviors and biological effects of ENMs, and ubiquitous dissolved organic matter (DOM) is bound to impact the interfacial interactions and the resulted environmental risks. Herein, we systematically investigated adsorptive interactions between ENMs and various DOM representatives, and thereby demonstrated the effects of DOM on the aqueous suspension/aggregation, mobility in porous media, adsorption of contaminants, transformation, and biological accumulation and toxicity of ENMs. Overall, we conclude that natural DOM can in general expand environmental distribution of ENMs while limit their toxicity to organisms.

工程纳米材料的环境行为和生物效应：界面相互作用和溶解有机物的重要作用

随着纳米技术的快速发展，反应工程纳米材料（ENM）越来越多地排放到环境中，在环境中它们与环境成分和生物相互作用，从而构成潜在的风险。纳米环境和纳米生物界面之间的相互作用形成决定了环境行为和ENM的生物学效应，无处不在的溶解有机物（DOM）必将影响界面相互作用和由此产生的环境风险。在本文中，我们系统地研究了ENM与各种DOM代表之间的吸附相互作用，从而证明了DOM对水悬浮液/聚集体，在多孔介质中的流动性，污染物的吸附，转化以及生物积聚和ENM的毒性的影响。总体，
