Three different HDPE geomembranes (GMBs) were analysed for PFAS content using targeted detection of six specific analytes and total fluorine (TF) measurements. To assess PFAS leachability under different conditions, extraction experiments were conducted using solutions with varying methanol concentrations. The results showed that perfluoropropionic acid (PFPrA), an ultra-short-chain PFAS, was detected in all tested geomembranes at concentrations ranging from below the limit of quantification (LOQ) to 0.44 µg/g. Importantly, PFPrA concentrations in two geomembranes (GMB2 and GMB3) manufactured at the same facility were comparable, whereas GMB1, produced at a different plant, exhibited concentrations nearly an order of magnitude higher. This disparity suggests potential differences in polymer processing aid (PPA) formulations, PFAS-containing additives, or variations in manufacturing processes. TF measurements for all samples fell below the reporting limit, indicating that large quantities of other PFAS were unlikely to be present. However, the high limit of quantification (LOQ) of 5 mg/kg for TF analysis likely resulted in excessive data censoring, highlighting the need for more sensitive TF detection methods. As regulatory pressures drive a transition toward PFAS-free polymer processing aids, a significant issue may arise if unregulated or unknown PFAS substitutes are used in place of regulated or guideline-referenced PFAS chemicals. Future research should investigate a broader range of geomembrane types and PFAS analytes, enabling more generalised conclusions to be drawn regarding the presence of PFAS in geomembranes.</div></div>","PeriodicalId":73763,"journal":{"name":"Journal of hazardous materials advances","volume":"18 ","pages":"Article 100723"},"PeriodicalIF":5.4,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143839735","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 effectiveness of the Fe/ZSM−5-coated membrane in rejecting Pb²⁺, Cd²⁺, Hg²⁺, and Cu²⁺ ions was systematically evaluated. SEM reveals coffin-like or intergrown Fe/ZSM−5 crystal structures. XRD highlights MFI framework reflections at 7–9° and 23–25° 2θ, corresponding to the (101), (020), (501), (151), and (303) planes. FTIR displays characteristic ZSM-5 bands at 401 cm⁻¹, 590 cm⁻¹, 679 cm⁻¹, 781 cm⁻¹, and 1101 cm⁻¹. BET analysis shows a smaller average pore radius of 1.704 nm, a higher surface area of 251 m²/g, and a larger pore volume of 0.214 cm³/g. The mZSM membrane demonstrated superior HM removal efficiencies in the order of Cu²⁺ (77.6 %) &lt; Hg²⁺ (85.6 %) &lt; Cd²⁺ (95.1 %) &lt; Pb²⁺ (98.8 %), outperforming the uncoated clay support. Water flux and permeation tests showed that the initial pure water flux of the clay support was 199 L·m⁻²·h⁻¹ (LMH), stabilizing at 144 LMH after 90 min, while the Fe/ZSM−5-coated membrane exhibited a significantly lower flux of 62.2 LMH due to reduced pore size and enhanced ion-exchange interactions. Electrochemical studies using Differential Pulse Voltammetry (DPV) confirmed that electrostatic repulsion played a dominant role in HM rejection rather than direct adsorption. However, the order of metal accumulation on the electrode surface (Cd²⁺ = 221 &lt; Pb²⁺ = 447 &lt; Cu²⁺ = 654 μA &lt; Hg²⁺ = 667) differed from the filtration order. This discrepancy suggests that only the preconditioning potential can elucidate the fouling mechanism of HM at the mZSM membrane surface.

The effectiveness of the sorbents in removing selected PFAS compounds from landfill leachate followed the order PFHxS &gt; PFOA &gt; PFBS &gt; PFBA. PFBA and PFBS reached maximum removal of 85–99.99 % at the highest sorbent dosage (500 mg/10 mL), while PFOA and PFHxS achieved &gt;99.99 % removal at dosages exceeding 200 mg/10 mL and 50 mg/10 mL, respectively. Sorption kinetics data for all PFAS compounds were best described by the pseudo-second-order (PSO) model, thus inferring that both physisorption and chemisorption occurred on the surface of the adsorbents. The experimental sorption isotherms suggest that the interactions between PAC and short-chain PFAS were primarily driven by multilayer adsorption on a heterogeneous adsorbent surface. Notably, none of the isotherm models employed in this study adequately explained the adsorptive behaviour of long-chain compounds on the PAC sorbents. Short-chain PFAS (PFBA and PFBS) exhibited reversible sorption, whereas long-chain compounds (PFHxS and PFOA) demonstrated stronger binding, highlighting the impact of chain length on PFAS retention. Overall, the data presented herein suggest that incorporating PAC into GCLs could effectively mitigate the migration of long-chain PFAS through geosynthetic composite lining systems. While migration of short-chain compounds was retarded, these continue to be significantly more challenging to contain with traditional treatments.</div></div>","PeriodicalId":73763,"journal":{"name":"Journal of hazardous materials advances","volume":"18 ","pages":"Article 100710"},"PeriodicalIF":5.4,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800109","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}

Its production is projected to reach a growth rate of 65 million metric tons by 2030. Our research aims for simultaneous thermal treatment of PVC through its co-pyrolysis with selected Zn-based transition metal oxides (MO) namely ZnO, ZnFe₂O₄, and NiZnFe₄O_4. Such an approach eliminates chlorine emission and enables to facilitate the isolation and extraction of the valuable zinc load in these MOs. These mono-tri Zn-based MOs are considered since they represent the zinc content in the electric arc furnace dust (EAFDs); another category of hazardous waste. The main aim of the work is to assess the likely selective extraction of the zinc load when compared to that of iron. TGA analysis indicates a strong interaction between the MO's and PVC, implying that the MO's act as potent catalysts for the dechlorination and cracking of the PVC structure. The co-pyrolysis of PVC with metal oxides at temperatures between 300 and 500 °C led to the production of metallic chlorides, as confirmed by XRD measurements. Based on IC measurements, PVC with ZnO mixture captured 91.13 % of the emitted HCl, whereas ZnFe₂O4 and NiZnFe₄O₄ seized the HCl emission to 65.78 % and 83.56 %, respectively. Further, EDX mapping disclosed the elemental composition of the solid residue after the reaction. The formation of Lewis acids such as ZnCl₂, FeCl₂, and NiCl₂ during the pyrolysis reaction triggered the isomerization of <em>cis</em> to trans olefins, which activated the PVC chain and made it less favorable to undergo cyclization reactions. Accordingly, the GCMS revealed, with the inclusion of MO's, a significant depreciation in the formation of benzene derivatives, heterocyclic compounds, and polyaromatic hydrocarbons, whereas it enhanced the formation of alkanes. For all temperature ranges, a high amount of aliphatics were formed with ZnO, with a peak value of 60.19 % at 500 °C. With a relative yield of ≈9–11 %, octane dominates in the produced hydrocarbons, which is considered the most efficient fuel due to its effective combustion. Moreover, the co-pyrolysis results at the temperature range of 300–500 °C suggest the potential for extracting the metals from the metallic chloride by different extraction techniques.</div></div>","PeriodicalId":73763,"journal":{"name":"Journal of hazardous materials advances","volume":"18 ","pages":"Article 100717"},"PeriodicalIF":5.4,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143820840","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}

Following uranium extraction, residual materials (tailings) containing these elements in partially immobilized forms are placed in the McClean Lake plant Tailings Management Facility (TMF). Uranium tailings are sulfate-rich low-level radioactive waste containing ²²⁶Ra, with activities of up to 3000 Bq/g. Barium chloride (BaCl₂) is added to precipitate ²²⁶Ra in barite as a solid-solution. Following this neutralisation treatment, ²²⁶Ra in the tailings is generally considered as sequestered in barite and sorbed onto ferrihydrite. To assess the subsequent stability of ²²⁶Ra in the tailings, an extensive study of its retention potential was performed. Characterisations incude assessment of tailings pore water and solids chemistry, tailings mineralogy, cation exchange capacity measurement, scanning electron microscopy and energy-dispersive x-ray spectroscopy (SEM/EDS), and alpha-autoradiography analyses supplemented with thermodynamic modelling.

A (Ba,Ra)SO₄ solid-solution regulates the average ²²⁶Ra concentration now and over the long term, through a distribution coefficient which is subject to a gradual shift towards a recrystallisation equilibrium. Recrystallisation causes an increase in the long-term concentration of ²²⁶Ra in the tailing water to 10 Bq/L.

One of these nature-based solutions is the use of organic amendments. Most organic amendments serve as a source of beneficial microbes, nutrients, and carbon for replenishing soil carbon stock and enhancing soil biological and biochemical processes. Thus, they are essential in maintaining soil biodiversity, promoting crop yield, and contributing to soil carbon sequestration. Harnessing organic amendments in soil carbon sequestration has led to using various organic materials such as biochar, animal manure, plant litter, coal gangue, and straw to enrich soil carbon stock.
