ENAGenomicsUNLOCKhttps://www.ebi.ac.uk/ena/browser/view/PRJEB89879Organic micropollutants (OMPs) such as pharmaceutical residues, personal care products, pesticides, and industrial chemicals are increasingly detected in surface waters at low concentrations (ng/L to µg/L), posing ecological risks due to their bioactive nature. Wastewater treatment plants (WWTPs) are a major source of OMPs in the environment, as conventional WWTP processes primarily target bulk carbon, nitrogen, and phosphorus removal and are not optimized for OMP elimination. The updated European Urban Wastewater Treatment Directive mandates 80% removal of 12 priority OMPs from large WWTP effluents by 2035. Advanced treatment technologies like ozonation, activated carbon sorption, and nanofiltration have demonstrated efficacy in OMP removal but face challenges including high energy demands, by-product formation, and waste management issues. Constructed wetlands (CWs) offer a promising low-energy alternative, combining natural processes such as sorption, biodegradation, plant uptake, and photodegradation to remove contaminants. CWs enhanced with organic sorption materials like biochar show improved OMP removal, although the durability of this enhanced sorption over time remains unclear. This study investigates the longevity of enhanced OMP sorption in a tidal-flow constructed wetland using woodchips and biochar substrates over three years, assessing OMP removal efficiency, transformation product formation, and microbial community dynamics to understand the role of biodegradation and the potential for in-situ regeneration of sorption materials.ENAfalseBiodegradation of organic micropollutants in tidal flow constructed wetlands with enhanced sorption substrate: Transformation products and microbial community compositionWetland2025-08-302025-08-30PRJEB89879
