Dissolved organic matter (DOM) is ubiquitous in the environment and has high reactivity. Once engineered nanoparticles (ENPs) are released into natural systems, interactions of DOM with ENPs may significantly affect the fate and transport of ENPs, as well as the bioavailability and toxicity of ENPs to organisms. However, because of the complexity of DOM and the shortage of useful characterization methods, large knowledge gaps exist in our understanding of the interactions between DOM and ENPs. In this article, we systematically reviewed the interactions between DOM and ENPs, discussed the effects of DOM on the environmental behavior of ENPs, and described the changes in bioavailability and toxicity of ENPs caused by DOM. Critical evaluations of published references suggest further need for assessing and predicting the influences of DOM on the transport, transformation, bioavailability, and toxicity of ENPs in the environment.
溶解有机质（DOM）在环境中无处不在，具有很高的反应活性。一旦工程纳米颗粒（ENPs）被释放到自然系统中，DOM 与 ENPs 的相互作用可能会显著影响 ENPs 的归宿和迁移，以及 ENPs 对生物的生物利用度和毒性。然而，由于 DOM 的复杂性和有用的表征方法的缺乏，我们对 DOM 与 ENPs 之间相互作用的理解存在很大的知识空白。在本文中，我们系统地综述了 DOM 与 ENPs 之间的相互作用，讨论了 DOM 对 ENPs 环境行为的影响，并描述了 DOM 引起的 ENPs 生物利用度和毒性的变化。对已发表文献的批判性评价表明，需要进一步评估和预测 DOM 对 ENPs 在环境中的迁移、转化、生物利用度和毒性的影响。
