To reduce these volumes, mining companies can valorize them as construction materials for cover systems such as cover with capillary barrier effects (CCBE). However, questions remain related to the geochemistry of the leachate that percolates through CCBEs made from mining materials. Limestone amendment can be used for increasing the neutralizing potential (NP) of mining materials in the case where the materials have a risk to generate contaminants. This study aims at assessing the performance of low-sulfide tailings, amended or not, and non-acid generating waste rock as components of CCBEs. To do so, five column tests were conducted in the laboratory to assess the long-term geochemical evolution of waste-rock, low-reactive tailings (2 % pyrite), tailings amended with 8 wt% of limestone, CCBE with the moisture-retaining layer (MRL) made of low-reactive tailings (CCBE-T), and CCBE with the MRL made of amended tailings (CCBE-TA). The geochemical evolution of leachates from the different column tests was simulated with MIN3P, a multicomponent reactive transport model. The numerical model was calibrated using results from the column tests. Long-term simulations using the short-term calibrated models suggested that low-reactive tailings could produce AMD when exposed to laboratory conditions, while limestone amendments effectively neutralized the generated acidity and stabilized the pH. Furthermore, incorporating tailings as a MRL in a CCBE reduced sulfide oxidation in the long-term due to the high degree of saturation that limited oxygen diffusion and sulfide reactivity.</div></div>","PeriodicalId":15530,"journal":{"name":"Journal of contaminant hydrology","volume":"272 ","pages":"Article 104564"},"PeriodicalIF":3.5,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Under optimized conditions of 6 (pH), 200 (rpm), and 30 (minutes), 97.34 % removal was observed, and 48.65 mg. g⁻¹ uptake capacity of the adsorbent was achieved. The adsorption process obeyed the Langmuir model with monolayer adsorption on a surface. It conformed with a pseudo-second-order kinetic model (R² = 0.9878), indicating that the chemisorption is the rate-controlling step. Thermodynamic analyses showed that the adsorption process is exothermic and spontaneous, thus confirming the feasibility and eco-friendliness of the potential low-cost adsorbent for MTB dye removal from wastewater. The AONPs after methylene blue dye removal, were integrated into clayey soil at an appropriate concentration of 1 % to assess their influence on geotechnical parameters. Experimental findings indicated substantial enhancements, with maximum dry density rising from 1660 kg/m³ to 1700 kg/m³ and unconfined compressive strength increasing from 143.9 kPa to 198.6 kPa, with a decrease in plasticity index and liquid limit. These improvements are attributed to the nanoparticles' capacity to occupy soil voids, reduce porosity, and increase interparticle bonding. Applying AONPs offers a cost-effective and eco-friendly method for treating dyes in wastewater, while concurrently enhancing soil characteristics and promoting sustainable wastewater treatment and soil stability.</div></div>","PeriodicalId":15530,"journal":{"name":"Journal of contaminant hydrology","volume":"272 ","pages":"Article 104553"},"PeriodicalIF":3.5,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143838306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The river reaches downstream of the inlets from the WWTPs presented the highest PEC of AZ, whereas a reduction of PEC was simulated moving downstream of the inlets. The results of the ecotoxicological risk assessment showed that in March most of the river network presented a PEC of AZ higher than the Predicted No-Effect Concentration (PNEC).

Hydrogeochemical analysis, along with multiple statistical methods and the Redfield ratio, revealed that geogenic processes were the dominant drivers of groundwater P enrichment, accounting for 77.5 % of the samples, while anthropogenic activities, particularly intensive agriculture, densely residential area and industrial development, contributed to P inputs in 22.5 % of the samples.

This study investigates the geochemical processes that govern nickel (Ni) removal in Filtralite and evaluates how different parameters influence its effectiveness. The interaction between contaminated water and Filtralite-forming minerals results in a rapid increase in pH, leading to the immediate precipitation of teophrastite (Ni(OH)₂) at the initial filtration stages. However, as water continues to interact with Filtralite, its capacity to maintain high pH levels declines over time, reducing the Ni removal efficiently. In regions with a Mediterranean climate and considering an infiltration system that manages runoff from 10 % of the urban landscape, a filter layer of 200 mm combined with flow velocities below 828 mm/h has been found to optimize metal retention. Under these conditions, more than 90 % of the filter's total Ni-holding capacity is effectively used, and replacement is expected to be necessary roughly every three years. Additionally, tests simulating intense rainfall confirm that the eliminated Ni remains securely bound within the filter media, reinforcing Filtralite's reliability as a filtration material for infiltration systems. This research contributes to a better understanding of the geochemical mechanisms involved in metal removal and lays the groundwork for future design considerations in Filtralite-based filtration applications.</div></div>","PeriodicalId":15530,"journal":{"name":"Journal of contaminant hydrology","volume":"271 ","pages":"Article 104548"},"PeriodicalIF":3.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A source-apportioning approach was utilized to delineate the possible sources of pollution and conducted a risk assessment attributed to exposure to microplastic pollution. The results suggest that the solid waste dumping zone exhibited the highest microplastic abundance, followed by the cage farming zone. Fiber-shaped microplastic particles were abundant in cage farming and open fishing zones, while films dominated the solid waste dumping zone. FTIR analysis revealed that polyamide and polyester, widely used for regional fishing nets, were dominant in cage farming and open fishing zones, while polyamide, polystyrene, and polyethylene were dominant in solid waste dumping zones.
