Initially, sediments act as sites of fixed-nitrogen removal via efficient nitrification–denitrification coupling. However, with continued organic loading, they shift to retaining fixed nitrogen and exporting ammonium. In lab-based sediment microcosms, we measured sediment–seawater fluxes of nitrate + nitrite (NOx), ammonium (NH4+), and dinitrogen (N2) following short-term additions (1 and 7 days) of fresh fish waste across moderate (1.1–3.2 g C m–2 d–1) to heavy (11.2 g C m–2 d–1) loading scenarios. After 1 day, NH4+ was efficiently converted to N2. After 7 days, however, organic carbon accumulated and NH4+ export dominated. 16S rRNA gene sequencing revealed that this shift in function was linked to reduced nitrification efficiency, increased dissimilatory nitrate reduction to ammonium (DNRA), and potential stimulation of nitrogen fixation. Our findings suggest that sustained organic enrichment from open-ocean aquaculture can disrupt benthic nitrogen removal processes and promote fixed-nitrogen retention with potential consequences for coastal nutrient dynamics. These results have important implications for the ecological sustainability of offshore aquaculture and can inform ecosystem-based management strategies.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 6","pages":"2891–2902 2891–2902"},"PeriodicalIF":4.8,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144269478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The city of Ouagadougou is strongly confronted with this problem of wastewater discharged by some pollution sources, such as industries. This work aims to use ecological and low-cost purification methods to remove organic pollutants from industrial wastewater using natural clay from Burkina Faso. The results were obtained by the batch mode experiment. With 1 g of clay, at free pH of wastewater, the results showed that the rise in temperature leads to an increase in chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) removal. This effect is very remarkable from 35 °C with removal rates approaching 100% for BOD5 and 50% for COD. In addition, the study of the raw clay dosage effect from 1 to 5 g per 100 mL of wastewater showed an increase of the raw clay dosage removal rates in COD and BOD5 to above 70% for 5 g of adsorbent. The maximum removal rate achieved is 70% for COD and 98% for BOD5 with the optimum temperature of 37 °C. The optimum dosage would be 5 g per 100 mL of wastewater with a contact time of 20 h.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 6","pages":"3216–3229 3216–3229"},"PeriodicalIF":4.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144269871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies have used diffusive gradients in thin-films (DGT) passive sampling techniques to investigate the occurrence of pharmaceuticals in natural waters. In this study, a self-developed DGT sampler was used to determine concentrations of 35 pharmaceuticals in 42 surface water sampling sites from the North Canal Basin, an urban catchment in Beijing, China. A total of 26 pharmaceuticals were detected with total concentrations ranging from 85.2 to 8800 ng/L, and ritonavir was the dominant pharmaceutical with the highest mean concentration of 46.2 ng/L. The spatial distribution indicated that the wastewater treatment plants were the major source of pharmaceuticals in the study area. Besides, pharmaceutical concentrations gradually increased from upstream to downstream along the mainstream, which could be attributed to the transfer of pharmaceuticals with the water flow. The result of the multilevel ecological risk assessment showed that ritonavir and diclofenac posed the most significant ecological risk (medium risk) to aquatic organisms, which means that high concern and priority control are required. This study was the first attempt to apply the DGT to the North Canal Basin in Beijing, enriching the data on pharmaceutical contamination and providing a scientific basis for environmental managers.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 6","pages":"3469–3478 3469–3478"},"PeriodicalIF":4.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144269866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were collected through key informant interviews (n = 27), focus group discussions, and an online survey (n = 167). The triangulation of these methods provided a comprehensive understanding of stakeholder perspectives across various sectors including water treatment plant managers, government officials, regulators, and landowners. Key themes include regulatory hurdles, funding challenges, and the necessity for robust water quality monitoring systems. Regulatory constraints were consistently identified as a primary barrier, highlighting the need for policy reforms to facilitate green infrastructure. Funding availability was another critical challenge, with stakeholders emphasizing the importance of new financing models and incentive-based programs. Continuous water quality monitoring to establish baselines and measure the impacts of restoration projects is also emphasized. Efforts to improve local policy and regulatory frameworks could significantly bolster watershed restoration practices, enhancing riverine water quality and providing broader environmental and social benefits.As growing environmental pressures and aging gray infrastructure challenge water systems, this research explores behavioral barriers and enablers to adopting nature-based solutions for cleaner water, engaging key stakeholders in the U.S. water sector.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 6","pages":"2945–2952 2945–2952"},"PeriodicalIF":4.8,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsestwater.4c01053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144269553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transport experiments were performed with different fracture orientations using kaolinite particles and dissolved fluorescein under different flow velocities. The experimental data were fitted to a model based on the advection–dispersion equation. The transport parameters were conducted and correlated to the flow velocity and the fracture orientation. The results revealed that an increase in fracture orientation vertically leads to earlier breakthrough curves and a higher recovery. The increase in the fracture orientation reduces the particle–fracture surface interaction. Fracture orientation has a negligible effect on the transport of fluorescein. Kaolinite particles are transported faster than fluorescein at all fracture orientations due to the size-exclusion effect. Particle dispersion is more important for greater orientations since particles can sample the entire flow velocity. Further investigations on particle size are necessary to understand in-depth the impact of fracture orientation on particle dispersion. As the fracture orientation increases, the probability of particle collision with the fracture surface decreases, leading to a decrease in the filtration coefficient. By using experimental methods, this study contributes to the advancement of understanding the effect of fracture orientation on the transport of particles.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 6","pages":"2975–2982 2975–2982"},"PeriodicalIF":4.8,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144269566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
