Redox-sensitive multi-contamination scenarios in freshwater systems present unique challenges, particularly when contaminants require simultaneous but opposite redox conditions for effective remediation. This session focuses on the complexities and innovative solutions for managing co-contamination where one contaminant requires oxidation while another requires reduction—a scenario that represents one of the most challenging tasks in environmental remediation. Topics of interest include:
• Mechanistic insights into the simultaneous oxidation-reduction (redox) processes required for the effective treatment of co-contaminated freshwater systems.
• Advanced strategies for spatial or sequential redox manipulation to manage contaminants with conflicting redox requirements, such as the simultaneous reduction of nitrates and oxidation of organic contaminants or heavy metals.
• Novel materials and technologies (e.g., redox-active media, bioreactors, and nanomaterials) designed to achieve controlled redox environments for selective contaminant removal.
• Integrated modeling and monitoring approaches to predict and manage the complex interactions between redox processes and contaminant behaviour.
• Case studies showcasing real-world applications and the challenges faced in designing and implementing such complex remediation strategies.
This session seeks to engage researchers, practitioners, and policymakers in discussions on advancing the science and technology of redox-sensitive co-contamination management. Join us to explore novel approaches, share experiences, and collaborate on solutions for one of the most difficult tasks in environmental remediation.
