Phthalic acid esters (PAEs) and organophosphate esters (OPEs), widely used as plasticizers and flame retardants respectively, represent two additive categories of the greatest environmental concern due to their persistence and endocrine-disrupting properties. This study systematically investigated the dynamic release of PAEs and OPEs from polyethylene (PE) and biodegradable poly (butylene adipate-co-terephthalate)/polylactic acid (PBAT/PLA)-based films under four simulated agricultural conditions: Natural conditions (NC), UV irradiation (UV), high temperature (HT), and flooding (FC). Uncultivated soil exhibited Σ₈PAEs and Σ₇OPEs approximately of 1317.5 ng/g and 1931.1 ng/g, respectively. During a 360 d incubation period, the contents of PAEs in soil surged during a short-term period, which may link to the desorption of adsorbed contaminant. Biodegradable films released higher PAEs concentrations than PE films, with secondary contamination peaks emerging 180–360 d post-incubation. Scanning electron microscopy (SEM) observations revealed that structural degradation (e.g., cracks/holes) during early degradation (0–180 d) unexpectedly amplified additive leaching in later stages, contrasting with assumptions of reduced contamination risks over time. UV irradiation had a photo-degradation effect on PAEs further accelerated the release of pollutants by 25–40 %, while high temperature and flooding conditions showed limited promoting effects along with NC conditions. These findings highlight the need for additive-free formulations and environment-specific mulch management policies to mitigate soil contamination risks.</div></div>","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"377 ","pages":"Article 126467"},"PeriodicalIF":7.6,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066742","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}

Clarifying the distribution characteristics of soil organic carbon (SOC), microbial properties (e.g. microbial abundance/diversity, soil enzyme composition/activity) and persistent organic pollutants (POPs) in soil aggregates, along with influencing factors such as aggregate size, specific surface area (SSA), and nutrient content, is crucial for grasping POPs degradation mechanisms in soil. This study reviewed existing literature and identified that SOC mainly accumulated in 0.25–2 mm aggregates, then &gt;2 mm, 0.053–0.25 mm, and &lt;0.053 mm ones. Meta-analysis revealed that microbial abundance and diversity were significantly lower in &gt;2 mm aggregates (p &lt; 0.05), with no difference in the other three. Soil enzyme activities did not show significant variations across different aggregates. Soil nutrients exerted the most pronounced influence on microbial communities within the 0.25–2 mm aggregates whereas the enzyme activities were prominent within the &lt;0.053 mm and &gt;2 mm aggregates, with a generally positive effect. PAHs are mainly distributed in &lt;0.053 mm fractions. For different types of POPs, their distribution in the soil is closely related to their own species characteristics, while their content in aggregates shows a significant positive correlation with SOC and SSA. The heterogeneity in SOC, microbial properties, and POPs distribution increased POPs degradation complexity. Our study provides a basis for understanding POPs environmental behavior and insights for soil remediation.

The presence of UV filters (UVFs) such as benzophenone-3 (BP3) and octocrylene (OC), exacerbates this issue, particularly in coastal areas. This study presents an innovative dual-method approach combining high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) and differential pulse adsorptive stripping voltammetry (DPAdSV) to assess the adsorption of UVFs on polyethylene (PE), a widely found polymer in aquatic environments. Adsorption kinetics were analysed using pseudo-first-order (PFOM) and pseudo-second-order (PSOM) models, revealing a higher equilibrium sorption capacity for OC due to its stronger hydrophobic interactions with PE. A central composite design (CCD) was employed to enhance resources efficiency in experimentation and controlled experiments exposed the materials to both pure fresh water and synthetic seawater. The results indicate a higher adsorption affinity of OC on PE than BP3, attributed to its high octanol-water partition coefficient (log Kow 6.88) and stronger hydrophobic interactions. Exposure time was the most influential variable across both media, while pH and temperature had a significant effect on BP3 adsorption in synthetic seawater. Hydrophobic partitioning, aided by van der Waals forces, was identified as the dominant interaction mechanism for both UVFs, with π–π and electrostatic interactions playing minimal roles due to the nature of the polymer. The study provides new insights into how polymer–pollutant interactions vary across environmental conditions and offers a novel voltammetric alternative for in-situ UVFs monitoring.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"16 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066739","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}

This study proposes a novel, dynamic framework for in situ bioremediation of BTEX-contaminated groundwater at the Shiraz oil refinery site, integrating the Micro-Exposure Event (MEE) method as a central component for high-resolution, time-sensitive health risk assessment. Unlike conventional risk models that rely on long-term average concentrations, the MEE approach evaluates individual exposure events across temporal intervals, enabling the identification of short-term contaminant spikes that may otherwise go undetected. This enhances the accuracy and responsiveness of risk estimations, particularly in heterogeneous aquifer settings. To address the site's geological complexity—characterized by variable stratigraphy, non-uniform flow directions, and multiple pollution sources—the framework couples advanced simulation tools (MODFLOW 6 and MT3D-USGS) with adaptive optimization algorithms. A Genetic Algorithm (GA) is employed for spatial optimization of well placement, while Differential Evolution (DE) is used for temporal adjustment of injection and extraction rates. Simulation results over a ten-year period demonstrate a 92% reduction in benzene concentrations and sustained health risk levels below the U.S. EPA threshold of 1×10^-6. Additionally, the optimized strategy achieves an 18% reduction in total operational costs compared to baseline scenarios. By linking MEE-based risk evaluation with simulation-optimization techniques, the proposed framework offers a replicable and scalable approach for managing BTEX pollution in complex subsurface environments. It advances the state of practice by balancing environmental performance, cost-efficiency, and health protection in groundwater remediation.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"1 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143980137","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}

This study investigated the relationship between elemental concentrations in <em>Fucus vesiculosus</em> transplants (both fresh and dried) and seawater samples representative of the transplants’ exposure period collected using autosamplers. The transplants were deployed across 22 coastal sites in northwest Spain over 14 days. No significant correlations were found between seawater elemental concentrations and those in transplants for any element. Similarly, seawater physicochemical properties (pH, dissolved oxygen, conductivity, and temperature) and the pre-exposure concentrations in transplants had minimal influence on post-exposure levels. Elemental concentrations in native seaweeds at the exposure sites were not correlated with those in transplants (except for Zn in the fresh transplants) and did not reflect seawater concentrations either. These findings highlight that element concentrations in seaweed do not follow a straightforward linear relationship between exposure and tissue concentrations. Instead, they result from a complex interplay of various, yet unknown environmental factors that influence element bioavailability in the water and the physicochemical properties of the seaweed. This complexity calls into question the suitability of seaweed transplants as effective biomonitors for marine pollution.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"44 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143980141","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}

Therefore, there is a need for water management strategies that can reduce Cd accumulation in rice without the substantial resource demands of CF. Field trials conducted in Cd-contaminated paddy fields in southern China compared eight water management strategies, including continuous drainage (CD), stage-specific flooding, and CF, to identify alternatives for reducing rice Cd accumulation. Delaying flooding stages and extending flooding duration progressively decreased Cd levels in rice tissues. Although CF achieved the lowest brown rice Cd levels (0.04–0.06 mg/kg), it also caused yield reductions. Among the alternatives, grain-filling stage flooding resulted in a reduction of Cd levels in brown rice compared to vegetative-stage flooding, decreasing the health risks of Cd from intake of brown rice. Specifically, grain-filling stage flooding for 20 days (FG20) was particularly effective, reducing Cd concentrations in brown rice by 82.74 % (YA) and 28.61 % (HG) compared to CD, and by 3.67 %–74.82 % compared to vegetative-stage flooding. FG20 significantly reduced soil Cd bioavailability to levels comparable to CF, while also similarly increasing soil pH and promoting iron plaque formation compared to CD. Additionally, FG20 modulated the soil microbial community, stimulating Cd-immobilizing bacteria (e.g., <em>Clostridium_sensu_stricto_13</em>, <em>Oxobacter</em>) while suppressing Cd-mobilizing bacteria (e.g., <em>Porphyrobacter</em>, <em>Anaerolinea</em>), stabilizing Cd in soil.
