Micro/nanoplastics (M/NPs) have become prevalent in aquatic environments due to their widespread applications. Likewise, ubiquitous ecological macromolecules can adsorb onto M/NPs form an “eco-corona”, which significantly alters environmental behaviors including aggregation dynamics, adsorption/desorption, and bioavailability. Therefore, it is necessary analyze the role of eco-corona assessing risks M/NPs. This review systematically summarizes formation mechanisms evaluates its regulatory effects on stability ecotoxicity Compared with other (e.g., natural organic matter extracellular polymeric substances), humic acid (HA) tightly binds through electrostatic hydrophobic interactions, affecting hetero-aggregation behavior colloidal stability. In terms bioavailability, various functional groups HA surface regulate charge hydrophobicity M/NPs, thereby bioaccumulation “Trojan horse” effect. Notably, corona alleviates M/NPs-induced growth inhibition oxidative stress. Genotoxicity assessment further showed that expression genes related stress response detoxification pathways. Future studies should focus synergistic between co-existing pollutants complex elucidate long-term associated formation.
