摘要
Emerging contaminants（ECs），including persistent organic pollutants，endocrine disruptors，antibiotics，and microplastics，are widely present in aquatic environments. Despite trace-level contaminants，they still pose a significant threat to water quality and human health. As a pretreatment process for improving drinking water quality，the riverbank filtration system has been proven natural，reliable，and low-cost for effectively eliminating the ECs existed in rivers. This study systematically reviews typical ECs，including their sources，fate，degradation transformation mechanisms，and interactions with the surrounding environment. The study highlights the typical degradation mechanisms of ECs in riverbank filtration systems，particularly the biodegradation mechanisms. Specifically，the removal process of ECs by biodegradation in riverbank filtration systems and corresponding influencing factors are summarized. New research directions for biodegradation of ECs in riverbank filtration systems are proposed. Our viewpoints shed light on future treatment strategies for global drinking water plants. ? 2023 Science Press.
