N-(1,3-dimethylbutyl)-N’-phenyl-p-benzoquinone (6PPD-Q) is an emerging environmental contaminant that widely distributed in aquatic environments and presents significant toxicological risks to organisms. As 6PPD-Q primarily derived from oxidative transformation of the tire antioxidant N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine (6PPD), its persistence potential for bioaccumulation organisms have raised widespread concerns. This study reviews sources, spatial distribution, migration, behaviors 6PPD-Q, as well degradation mechanisms different media. Additionally, this review systematically explores effects on organisms, including physiological, biochemical, molecular impacts fish, crustaceans, mollusks, algae, with a focus mechanisms. Finally, we discuss limitations current research propose key directions future studies, long-term ecological risk assessments, bioaccumulation, metabolic pathway analysis, optimization pollution control strategies, aiming provide scientific basis assessment management 6PPD-Q.
