微纳塑料与水生生态系统中溶解有机物之间的相互作用：从生态电晕动力学到微藻适应性恢复
Interplay between micro-nanoplastics and dissolved organic matter in aquatic ecosystems: From eco-corona dynamics to microalgal adaptive resilience.
摘要(中文译文)
塑料的广泛使用导致微/纳米塑料（MNPs）与溶解性有机质（DOM）在水生态系统中不可避免地共存并相互作用，这将对作为关键初级生产者的微藻的生理和生态功能产生不可避免的影响。本综述系统综合了DOM在MNPs共暴露条件下缓解微藻毒性的效应与机制，填补了理解DOM与MNPs毒理学相互作用方面的关键空白。首先，我们评估了MNPs与DOM之间相互作用动力学及其影响因素的最新进展。其次，我们整合相关定量分析，评估环境条件和微藻分泌的DOM如何调控MNPs的毒理学影响。关键的是，我们识别了DOM介导毒性缓解的四种关键机制，包括形成生态冠以屏蔽毒性位点、清除活性氧以缓解氧化应激、调控异聚集以降低生物可利用性，以及适应性分泌胞外聚合物以增强胁迫韧性。值得注意的是，天然DOM和微藻分泌的DOM均通过加速MNPs的光老化和表面氧化来重塑生态冠的组成和稳定性，从而改变毒性阈值。最后，本综述识别了关键知识空白并展望了未来研究方向，强调开发综合数据库、预测模型、生态逼真模拟和长期动态监测框架。本工作阐明了DOM作为生态冠动力学调节者和环境归趋调节者的双重角色，为整体解析MNPs的行为轨迹提供了新视角，同时丰富了水生生物多样性保护和生态系统韧性策略。
Abstract
The ubiquitous use of plastics has led to the inevitable coexistence and interaction of micro/nanoplastics (MNPs) and dissolved organic matter (DOM) in aquatic ecosystems, which will exert unavoidable impacts on the physiological and ecological functions of microalgae, the keystone primary producers. This review systematically synthesizes the effects and mechanisms by which DOM mitigates microalgal toxicity under MNPs coexposure, addressing the critical gap in understanding the toxicological interactions of DOM and MNPs. First, we evaluate recent advances in the dynamics of interactions between MNPs and DOM and their influencing factors. Next, we integrate relevant quantitative analyses to assess how environmental conditions and microalgal secreted DOM modulate the toxicological impacts of MNPs. Crucially, we identify four key mechanisms underpinning toxicity mitigation mediated by DOM. These include ecological corona formation to shield toxic sites, reactive oxygen species scavenging to alleviate oxidative stress, heteroaggregation regulation to reduce bioavailability, and adaptive extracellular polymeric substance secretion to enhance stress resilience. Notably, both natural and microalgae-secreted DOM reshape eco-corona composition and stability by accelerating MNPs photoaging and surface oxidation, thereby altering toxicity thresholds. Finally, the review identifies critical knowledge gaps and outlines future research directions, emphasizing the development of integrated databases, predictive models, ecologically realistic simulations, and long-term dynamic monitoring frameworks. This work elucidates DOM's dual role as an eco-corona dynamics modulator and environmental fate regulator and provides novel perspectives to holistically decipher behavioral trajectories of MNPs while enriching strategies for aquatic biodiversity conservation and ecosystem resilience.
