However, the N₂-selective ECDN remains challenging due to the sluggish kinetics of N–N coupling during NO₃⁻ reduction. Here, we developed a novel electrocatalyst of dual single-atomic sites on double-shelled mesoporous carbon spheres (FeNC@MgNC-DMCS) using a continuous sequential modular assembly and pyrolysis approach. The outer Mg–N₄ shell creates medium basicity sites that function as the proton fence, which optimizes the spatial distribution of H∗ species and suppresses ∗N protonation pathways that would otherwise lead to ammonia formation. Concurrently, the inner Fe–N₄ shell promotes N–N coupling for N₂ production. 92.8% NO₃⁻ removal and 95.2% N₂ selectivity was achieved by the optimized FeNC@MgNC-DMCS catalyst. Furthermore, long-term flow cell testing demonstrated remarkable durability, highlighting the practical potential of FeNC@MgNC-DMCS for sustainable wastewater treatment applications. This work introduces a catalyst design paradigm that integrates a proton-repelling interface to decouple H∗ availability from N₂ formation pathways, thereby enabling the development of high-performance ECDN catalysts with balanced activity and selectivity for environmental remediation applications.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 3","pages":"Article 100172"},"PeriodicalIF":17.6,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144766667","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}

We took measurements of indoor O₃ concentrations based on low-cost sensors in 18 cities in China, along with ambient O₃ concentration, meteorological factors, and a binary window status indicator as a proxy for ventilation behaviour, to establish random forest models. The results showed that including window status as a predictor improved model performance, with the cross-validation R² increasing from 0.80 to 0.83 and the root mean square error (RMSE) decreasing from 7.89 to 7.21 ​ppb, highlighting the importance of considering ventilation behavior in enhancing model accuracy. The model also effectively captured hourly variations in indoor O₃, revealing that indoor O₃ concentrations were consistently lower and more stable than outdoor levels. These differences suggest that relying solely on ambient data may misrepresent true personal exposure, underscoring the need to incorporate indoor exposure in assessments.

Since widowhood is a common event that can increase individuals' susceptibility to the environment, it is of great importance and interest to elucidate the widowhood disparity in mortality attributable to heat waves and O₃. We therefore conducted a case-crossover study of 1,214,763 nonaccidental deaths in Jiangsu Province, China, during 2015–2021 to investigate the independent and interactive associations of exposure to heat waves and O₃ with mortality by widowhood status. Grid-level heat waves were defined by multiple combinations of apparent temperature thresholds and durations. Residential heat waves and O₃ exposures were assessed using validated grid datasets. Conditional logistic regression models were applied for exposure-response analyses and evaluations of additive interactions. Exposure to heat waves and O₃ was significantly associated with increased odds of mortality in both widowed (odds ratio for heat waves, 1.25; O₃, 1.06 per interquartile range increase) and married subjects (1.08; 1.03), and these associations were higher in widowed subjects. A significant synergistic interaction was observed between heat waves and O₃, which was stronger in widowed subjects (relative excess odds due to interaction, 0.14 vs. 0.03). Up to 6.43% and 3.56% of deaths were attributable to heat waves, O₃ pollution, and their compound events in widowed and married subjects, respectively. Our findings suggest that widowed individuals are more susceptible to heat waves and O₃ and highlight the need to consider differences associated with widowhood disparities in preventing premature deaths due to heat waves and O₃ exposures.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 3","pages":"Article 100169"},"PeriodicalIF":17.6,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739686","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}

Hyperaccumulator plants have garnered significant attention for their potential to remove pollutants from contaminated soil.

One promising strategy is to genetically engineer <em>Oryza sativa</em> (rice) to hyperaccumulate As for effective phytoremediation of paddy soil. A key challenge remains in increasing metal accumulation without compromising tolerance. Here, <em>PvACR3</em> from the As hyperaccumulator <em>Pteris vittata</em> was introduced under the control of a rice root-specific promoter <em>pLsi1</em> to create high-As-accumulating and tolerant transgenic remediation rice. The remediation rice strains exhibited robust growth, with shoot As concentration reaching up to 451–557 ​mg/kg in a hydroponic experiment with 20 ​μM NaAsO₂ treatment, and 45.9–80.3 ​mg/kg in pot experiments with moderately As-contaminated paddy soils. Compared to wild-type rice, the <em>pLsi1::PvACR3</em> transgenic rice removed 23.5 times more As from the same paddy soils. By harvesting rice shoots before grain filling, the soil pore water As was almost completely depleted, and the acid-soluble and reducible fractions of As were significantly reduced.

In this study, a method for quantifying soil poly(butylene adipate-co-terephthalate) (PBAT) microplastics was developed, and their degradation behavior in three different soils was investigated. PBAT was quantified by analyzing the content of the monomer terephthalic acid (TPA) released during thermally assisted alkali hydrolysis, using liquid chromatography-mass spectrometry (LC-MS). For alkali hydrolysis, the use of capped bottle, water bath (90 ​°C for 30 ​min), and ultrasonication (100 ​kHz for 15 ​min) allowed for high-throughput sample processing in comparison to the use of round-bottom flask, reflux condenser, and stirring heating mantle. After 150 days, 10.8%–11.0% of PBAT microplastics were degraded in the acidic and neutral soils, while 17.1% were degraded in the alkaline soil, in line with the greatest lipase activity changes in the alkaline soil. This may be due to the fact that alkaline conditions favor initial depolymerization of PBAT, facilitating subsequent microbial attack. PBAT degradation products were also monitored, using solvent extraction combined with LC-MS and gas chromatography-mass spectrometry analysis. It was found that butanediol (up to 1580 ​μg/kg) accumulated to a higher level than TPA (about 50 ​μg/kg), especially in acidic and alkaline soils. Overall, this study, for the first time, precisely quantified the degradation of PBAT microplastics in soil. Further study is needed to better understand the fate of biodegradable microplastics in the soil environment and whether they will persist.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 3","pages":"Article 100166"},"PeriodicalIF":0.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144694741","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}

Greenness was estimated using satellite-derived Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) surrounding participants' home during pregnancy and post-birth period. Linear mixed-effect and random-effects logistic regression models were used to assess associations of greenness with CSHQ scores and sleep disturbance, respectively. Mediation effects of air pollution and residential distance to major roads were examined. Both prenatal and postnatal greenness exposures were significantly associated with better sleep outcomes. Specifically, an interquartile range increment in NDVI within the 250-m buffer during the entire pregnancy and from birth to investigation was associated with reductions in the total CSHQ score by 0.21 (95% confidence interval [CI]: 0.14, 0.28) and 0.22 (95% CI: 0.15, 0.29), respectively. Corresponding odds ratios for sleep disturbance were 0.96 (95% CI: 0.94, 0.98) for both periods. These associations remained consistent when considering larger buffers (500-m and 1000-m), and employing other greenness metrics like EVI and growing-season NDVI. The association between postnatal greenness exposure and sleep disturbance was partially mediated by PM_2.5, residential distance to major roads, NO₂, and SO₂. Children living in Northern China, breastfed for &lt;6 months, or with more educated mothers showed greater benefits from greenness.

Critical gaps hinder China's strategies for WWTPs, particularly in identifying upgrade needs, optimizing performance, and assessing the local benchmark plants as references. This study addresses these gaps through greenhouse gas (GHG) emission accounting and impact factor analysis, using monthly data from 2232 WWTPs across China. A tiered assessment methodology was developed to evaluate the synergy between pollution reduction and carbon mitigation, including indicators, methodologies, and assessment criteria. Results indicate that indirect emissions from electricity and chemical consumption accounted for 59.9% of total GHG emissions. Key factors influencing these indirect emissions included plant scale, treatment processes, geographic area, operational load, electricity consumption, and influent quality. Through the tiered assessment, WWTPs were classified into three categories: priority control (861 plants), general control (730 plants), and maintenance (641 plants). Furthermore, 222 benchmark plants were identified as exhibiting optimal synergy between pollution control and carbon reduction. For 80% of the benchmark plants, the ranges for carbon emission intensity, influent COD, influent C/N ratio, electricity consumption intensity, and operating load were 0.258–0.482 ​kg CO₂e/t, 175–338 ​mg/L, 6.13–10.9, 0.149–0.260 ​kWh per tonne of influent, and 88.0%–110%, respectively. Achieving these benchmark standards across all WWTPs could lead to a 30% reduction in total GHG emissions.
