Abstract: Triazole fungicides are widely used in crop disease prevention and control due to their high efficiency, broad spectrum, and long shelf-life. Numerous studies have shown that with the continuous application of triazole fungicides, a large number of residual pesticides that have not been effectively utilized enter the soil or remain on plants, and ultimately enter water bodies through rainwater erosion or surface runoff, posing a threat to aquatic organism saquatic organisms. This review comprehensively summarized the residue statuses of triazole fungicides in water environments and the research progress on the toxic effects of these fungicides on aquatic organisms, which were fish, amphibians, daphnia, and algae from multiple perspectives including acute toxicity, oxidative stress, developmental toxicity, genetic toxicity, endocrine disruption, impact on organism metabolism, and combined toxicity. Furthermore, this review also explored the research emphasis and future directions of the aquatic ecotoxicology of triazole fungicides, aiming to provide references for the rational application and effective management of triazole fungicides and lay a theoretical basis for reducing their impact on aquatic ecosystems.
