Early warning of soil heavy metal (HM) pollution is essential for regional prevention and control. This study proposes an integrated framework for regional assessment and early warning of soil HM contamination. Pollution thresholds derived from a finite mixture distribution model (FMDM) were incorporated as optimized input parameters into an environmental capacity (EC) model to assess soil HM risks in Jiande City, southeastern China, and to forecast trends from 2018 to 2026. Bayesian maximum entropy (BME) was applied to characterize the spatiotemporal evolution of EC-based risk zones. Results revealed severe Cd pollution in 2018 and an overall medium EC level. From 2018 to 2026, EC continuously declined, accompanied by expansion of overload zones. At the 95% confidence level, overload areas expanded from 139 km² to 404 km², and at the 85% level from 176 km² to 610 km². Overload zones initially clustered in the northeast and southwest (2018-2022), primarily driven by high geochemical background, as supported by Cd isotope tracing, while emerging central hotspots after 2022 reflected growing anthropogenic inputs. Model validation using 2022 observations achieved an accuracy of 88.9%. Long-term simulations also highlighted limitations of the EC model. These findings support early-warning strategies for regional soil HM pollution.

Efficient removal of Sr2+ from radioactive wastewater is essential for the safe and sustainable development of nuclear power. Herein, three ferrous oxalatophosphates—(NH4)2Fe3(HPO4)2(C2O4)2 (NFPO), Na2[Fe(HPO4)C2O4] (SFPO), and K3[Fe4(HPO4)2(PO4)(C2O4)2]∙H2O (KFPO)—were synthesized via a one-step hydrothermal route and systematically evaluated for Sr2+ capture. NFPO exhibited the best overall performance, featuring broad pH tolerance, thermal stability, and reusability. Notably, in the presence of Ca2+ (optimal background concentration: 50 mg·L–1), Sr2+ uptake was markedly enhanced, reaching equilibrium within 50 min and achieving an experimentally saturated capacity of 308.95 mg·g–1 (313 K). To improve handling and applicability, NFPO was immobilized into polyacrylonitrile microspheres (NFPO/PAN), which maintained effective dynamic adsorption in fixed-bed tests. Characterization results demonstrate that the crystalline framework remains largely preserved during adsorption, with Fe remaining in the divalent state and an ion-exchange trend involving NH4+. Density functional theory (DFT) calculations are further used to provide a plausible atomic-scale interpretation: Sr2+ binding is energetically favored at oxygen-rich interfacial sites, while Ca2+ can promote Sr2+ capture by modulating local structure and electrostatic environment. This work highlights ferrous oxalatophosphates as promising adsorbents and provides an experimentally grounded and theoretically supported understanding for Sr2+ remediation.

Tyre wear particles (TWPs) are an emerging pollutant of concern due to their potential risks to ecosystems and human health, yet they remain absent from European pollution monitoring and risk assessment (RA) frameworks. This study introduces a novel scenario-based RA framework tailored to complex contaminants, using European regional seas as a case study. The framework applies three scenarios that reflect the availability of empirical data and guide when modelled exposure or hazard estimates must be used. This structured approach provides transparency and flexibility for emerging pollutants where conventional tools, such as species sensitivity distributions (SSDs), fail due to scarce, inconsistent, or non-comparable datasets. TWPs pose a dual challenge: they are both physical particles and carriers of tyre wear chemicals (TWCs), which leach into aquatic systems as tyre wear leachates (TWLs). Current evidence suggests TWCs drive most toxicity, but their quantification is hindered by overlapping sources, variable composition, and limited marine ecotoxicity data. To address these gaps, a riverine emission model estimated that 82 million–1.2 billion TWPs may enter European seas annually, with predicted concentrations of 0.0001–0.016 particles m³. The Mediterranean receives the highest annual load, followed by the North-East Atlantic, Black Sea, and Baltic Sea. While modelled TWP concentrations fall below generic microplastic thresholds, TWCs may pose unaccounted ecological risks. This study highlights the innovation of the three-scenario framework, identifies critical data and regulatory gaps, and calls for harmonised monitoring, improved toxicity testing, and integration of TWPs and TWCs into EU policy to advance Zero Pollution goals.
