Bank filtration (BF), a natural subsurface treatment process, offers a sustainable solution, but its performance and scalability require further validation. This study simultaneously assesses the performance of laboratory-scale and full-scale BF systems using a horizontal collector well (HCW), both receiving the same source water and aquifer materials, to remove DOM and TrOCs, and to investigate changes in microbial communities under equivalent residence times (20 days). The full-scale HCW system achieved a 63.0 % DOM removal rate compared to 37.0 % in laboratory-scale columns, effectively reducing biopolymers and humic substances through soil passage. Microbial analysis revealed distinct shifts, with Proteobacteria comprising 80.1 % of the full-scale filtrate compared to 59.1 % in the laboratory-scale. Total cell counts and microbial activity decreased by 85.0 % and 90.4 % in the full-scale system, respectively. The removal efficiency for 60 selected TrOCs varied by their properties: hydrophobic ionic compounds achieved high removal (91.2 %), while hydrophilic and neutral compounds, including perfluoroalkyl substances (PFAS), showed lower removal rates (37.3 % and 24.5 %, respectively). Pharmaceuticals, steroid hormones, and pesticides were effectively removed, with some exceeding 99.9 %. This study is the first to directly compare full-scale HCW and laboratory-scale BF systems under controlled conditions.

Spatial attention analysis revealed that offshore regions consistently received higher attention, indicating their critical role as informative and generalizable environmental references. Furthermore, exhaustive feature attribution experiments identified an optimal combination of eight environmental factors-including temperature, salinity, current velocity, precipitation, wind direction, dissolved iron, phosphate, and silicate-were found to significantly enhance prediction accuracy.

Mussel samples from the inter-tidal zones were severely contaminated by microplastics, mainly constituted by fibre/filament, thin films and beads. Polypropylene was identified as the predominant particle type by Fourier transform infrared (FT-IR) spectroscopy. To confirm the ingestion and to track the fate of microplastics in the digestive tract, organisms were fed with orange fluorescent polystyrene beads of 10 μm size along with algal feed at two different experimental concentrations. Short term impacts of exposure in controlled conditions led to abnormal feeding behavior in mussels. Substantial reduction in algal clearance rate and presence of microplastics in faeces and pseudofaeces confirmed the ingestion. Absence of significant differences in microplastic count in soft tissues post depuration implies possible retention of smaller sized particles.

Partial least squares path modeling (PLS-PM) revealed the pathway from environmental variables (pH and salinity) to phoD-harboring bacterial taxa in particle-attached fraction and then to phoD gene copies was the determinant process for AP activity; while AP activity in free-living fraction was mainly controlled by the pathway from dissolved inorganic phosphorus (DIP) to phoD encoding community structure and its gene abundance. Our study highlighted the importance of diverse phoD phosphorus mineralizers, such as some members from Actinobacteria (Actinomadura), Alphaproteobacteria (unclassified Rhodobacteraceae, Roseovarius, Mesorhizobium) and Betaproteobacteria (Ralstonia), while pstS-harboring community was composed of picocyanobacteria. In the outer estuary with the lowest DIP concentration, AP level was activated substantially herein, which corresponded well with the spatial distribution of phoD and pstS gene abundance. High number of phosphatase and transporter genes potentially implied effective hydrolyzation rate of DOP to supplement inorganic phosphorus in the estuary. Researches on the characterization and transformation of DOP are insufficient owing to their complex composition and extraction difficulty. In the recent study, we applied Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) to present a preliminary feature of DOP molecular composition in the PRE. The phosphoesters represented more than 95 % of total DOP, and CHOP compounds (mainly lipids) was a potential substrate for bacterial AP.
