The high surface area to volume ratio, crystallinity, and functional groups of MPs allows them to interact with a broad assortment of pollutants, including heavy metals, antibiotics, and persistent organic compounds.

This study investigated the field performance of a downpipe treatment system (DPTS) using waste seashells to remove aluminium, zinc, and copper from roof runoff. First-flush runoff samples were collected before and after treatment during 30 events over 18 months. Results showed that Zn (85–97%) and Cu (59%) in runoff were predominantly dissolved, while Al (71–90%) was mainly particulate. Metal concentrations were largely influenced by the roof material, and weak correlations were observed with climate characteristics. The DPTS effectively removed particulate metals from copper (76 ± 48% Cu, 80 ± 41% Al) and galvanised (75 ± 49% Zn, 74 ± 27% Al) roof runoff. It also removed dissolved metals from Zincalume® (53 ± 32% Zn, 60 ± 30% Al) and Aluminium (96 ± 5% Zn) roof runoff, sustaining performance over 542 days of operation. Metal removal was linked to initial concentrations, partitioning, and metal affinity for the filter media, with precipitation, where metals formed insoluble compounds, and adsorption, where metals bound to the surface of the shells, as potential mechanisms. This study demonstrates that repurposing waste seashells in roof runoff treatment offers a low-cost, scalable and easily retrofittable solution for treating heavy metal pollution at its source, directly supporting Sustainable Development Goals (SDG), particularly Clean Water and Sanitation (SDG 6), Responsible Consumption and Production (SDG 12), and Sustainable Cities and Communities (SDG 11).</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 2","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11270-025-07766-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biological treatment methods have challenges such as requiring extensive space and process time, high sludge production, and efficient management and operation demands. To overcome these challenges, electrochemical methods such as electrocoagulation (EC) and electro-Fenton (EF) can be efficient approaches due to their higher process speeds, minimal facility requirements, and easy operation which make them economically viable. In this study, electrochemical processes, including EC and EF methods were applied for wastewater treatment of a wheat starch industry. After preliminary experiments to identify the effective factors and ranges, the response surface method (RSM) was applied to design the experiments. In RSM seven factors were considered including initial COD, pH, electrode distances, process time, temperature, current intensity, and hydrogen peroxide concentration along with the COD removal efficiency as the response. Statistical analysis showed that hydrogen peroxide concentration and initial COD had the most significant impact, while pH had the least effect on COD removal in the electrochemical process. The optimum results showed that for synthetic wastewater with an initial COD range of 2000–4000 mg/L a COD removal of 75–85% for EC and 89–93% removal for EF were obtained. The results were validated for raw natural wastewater with 88% removal for EC and 92% for EF.
