天然有机质因自身的结构特点而参与着光化学反应与醌呼吸过程，并通过这两个重要过程对生态系统中营养元素及矿物元素的物质循环起着十分重要的作用。天然有机质对环境污染物转化的影响早已受到关注，然而其中的影响机制尚未明晰。近年来已有一些研究者发现天然有机质的光化学过程及醌呼吸过程与污染物的转化之间存在着耦合作用，因而对此方面的研究进行了系统性的综述，阐明了天然有机质的光化学过程与醌呼吸过程对环境污染物转化的影响及可能的机制，并强调天然有机质在光化学过程中作为“高活性反应微区”以及在醌呼吸过程中作为“电子穿梭体”对环境污染物的转化起着关键的作用。因此作者提出了天然有机质对环境污染物的转化起着介导的作用，并推测该介导作用是天然有机质影响污染物环境行为及生物效应的重要机制之一，也是污染物在天然环境中消减与解毒的重要途径。今后应加强对天然有机质介导环境污染物转化的机制的研究，明确该机制在污染物自然消减过程中的作用大小，同时可基于此机制发展一些如有机质含量丰富的湿地系统等环境污染控制与修复技术。

Natural organic matter participates in photochemical reactions and due to its structural features also in the quinone respiration process. These two environmental processes are important parts of the cycling process of nutrients and minerals in the ecosystem. It has long been concerned that there is also an impact of natural organic matter on environmental transformation processes of pollutants. However, the mechanisms involved are still not understood. In recent years, some researchers have found that there is a coupling between the conversion of pollutants with the natural organic photochemical process and quinone respiration process respectively. In this paper a systematic overview is given to summarize the current literature. The goal of this this paper is to clarify the impact of the photochemistry and quinone respiration processes of natural organic matter on the transformation of environmental pollutants with respect to the mechanisms possibly involved. It is emphasized that the natural organic matter acts as a‘reactive microreactor’ in the photochemical process and as a‘electron shuttle’ in the quinone respiration process. These two steps may play a key role in the transformation of environmental pollutants. As a conclusion the authors suggest that natural organic matter may be understood as a mediator in the transformation of environmental pollutants. In case of this mechanism natural organic matter has an extremely important role on the environmental behavior and biological effects of pollutants as well as on the attenuation and detoxification of pollutants in the natural environment. The authors suggest that mechanistic studies on the transformation of environmental pollutants mediated by natural organic matter should be strengthened in the future in order to clarify its importance in the natural attenuation of pollutants. Moreover, technologies for pollution control and remediation based on this mechanism, such as wetland systems rich in organic matter, could be developed.
