While each material has been studied independently, their combination represents a novel approach to resource recovery and waste diversion from landfilling or stockpiling. This study evaluated three BA sources blended with PG, focusing on total and leachable concentrations of trace metals and fluoride. Compared to United States federal regulatory risk thresholds for direct exposure, elevated levels of As were found in all samples (4.71–18.6 mg/kg), and Pb in MSWI BA samples (571–790 mg/kg). Blending with PG reduced the total Pb concentrations in several mix designs (91–673 mg/kg). Leaching analysis of each material revealed As, Cd, Sb, Cu, Pb, and fluoride concentrations as constituents of potential concern from either BA or PG samples. Blending PG (pH 2.31) and BA (pH 9–11) resulted in more neutral eluent that ranged from pH of 5.5–10.6, decreasing with increasing PG replacement. A notable reduction in the concentrations of As, Cd, Sb, and fluoride was observed with the blends, attributed largely to the pH modification in the final eluent or precipitation or sorption mechanisms. For each constituent evaluated, at least one BA-PG blend reduced concentrations below the regulatory screening limit. Fresh MSWI BA was most effective at reducing mobile Sb and fluoride concentrations, attributed to the elevated ettringite and portlandite found in fresh ash at an elevated pH. These findings suggest that with appropriate mix design and consideration of site conditions, BA-PG blends may offer a practical reuse pathway with reduced environmental impact. Future investigations involving site-specific dilution and attenuation in soil and groundwater can serve to evaluate the complete risk assessment of the blending approach.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"380 ","pages":"Article 144463"},"PeriodicalIF":8.1,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143911833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Mass spectrometry is currently heavily utilized for PFAS analysis and is capable of precise and selective measurements down to parts per trillion (ppt). However, these are labor-intensive laboratory-only methods that require a substantial expertise and specialized equipment, resulting in high cost and long waiting periods which limit their utility in providing rapid, high-quantity and data rich (large number of samples) PFAS contamination screening capability at both local and regional scales. A rapid and fieldable screening method is needed to improve surveying efficiency to enable prioritization of resources where in-depth standard analysis is required. In this manuscript, a novel emulsion extraction methodology is introduced which isolates PFAS from aqueous media. When paired with colorimetric techniques, the method facilitates rapid detection of PFAS at concentrations ranging from part-per-million (ppm) to part-per-trillion (ppt) within minutes; herein, we demonstrate visual (naked eye) colorimetric detection of PFOA below 30 ppt. This semi-quantitative emulsion extraction method represents a new means for concentrating PFAS for both detection and remediation purposes in a cost-effective and scalable manner. The cost to construct the prototype kit used in this study—which is indefinitely reuseable—using commercially sourced components and 3D printed housing was less than $150, with material costs per test of less than $2.

This work utilised two waste oil samples, WCO1 and WCO2, with free fatty acid (FFA) contents of 3.48 % and 1.05 %, respectively, exceeding the current standards’ limits.

Boron predominantly localizes in the core of precursor, leading to the formation of internal pores during calcination. These internal pores act as buffers that reduce the compressive and tensile stresses exerted on CAM particles during cycling. Consequently, the NCMB samples exhibit superior cycle retention compared to NCM. The rate performance is also enhanced, as evidenced by the increased lithium-ion diffusion coefficient, supported by cycling voltammetry results. On the other hand, NCMB6 shows deteriorated initial discharge capacity with the highest cation disorder. These findings demonstrate that the current boron level in LIB leachate can enhance capacity retention and rate performance, offering valuable insights for facilitating the recycling process of spent LIBs.

Gaseous NCl<sub>3</sub> concentrations decreased as pH increased (6.5–7.5) and temperature decreased (20–15<sup>o</sup>C). A model that included liquid-gas mass transfer (K<sub>L</sub>a) and first order decay in liquid (k<sub>dl</sub>) and gas (k<sub>dg</sub>) phases was calibrated. The value of k<sub>dl</sub> decreased as the Cl/N ratio increased (10:1–14:1) but increased as pH and temperature increased. Values of k<sub>dl</sub> and K<sub>L</sub>a were lower in real wastewater than in synthetic wastewater. Simulations with a sewer model revealed that with a fixed hypochlorite loading, peak headspace NCl<sub>3</sub> concentrations decreased as wastewater flow increased due to changes in Cl/N ratio. Increased air flow reduced headspace NCl<sub>3</sub> concentrations immediately downstream of the discharge due to dilution but had little effect further downstream. Wastewater pH impacted headspace NCl<sub>3</sub> concentrations by controlling the concentration of NCl<sub>3</sub> in the wastewater. Temperature influenced peak headspace concentrations through its impact on mass transfer and gas phase decay rates. This study provides insights that can be employed to develop sewer use bylaws that regulate hypochlorite discharges.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"380 ","pages":"Article 144451"},"PeriodicalIF":8.1,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143895171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
