Several cities have also experienced incidents where nocturnal O₃ concentrations did not decrease as expected, and instead remained at high levels (above 50 ppb). However, there have been few detailed studies on the causes of these events. The present study used air quality and meteorological monitoring data, along with the Hybrid Single-Particle Lagrangian Integrated Trajectory model, to investigate the causes contributing to nocturnal O₃ remaining at high values (NORHV) in Linfen City, a typical basin city in the Fenhe River Basin, characterized by severe O₃ pollution. These events are influenced by the individual or combined impacts of mountain-valley breezes, along with vertical and horizontal transport of O₃-rich air masses. In addition, the influencing mechanisms of three NORHV events were identified as: 1) the alternating effect of the descent of upper-level air masses enriched with O₃, CO, and SO₂ and downslope mountain breezes carrying the O₃-rich air mass; 2) the interaction between the transport of polluted air masses across mountains and downslope mountain breezes on both sides of the two mountains in urban areas; and 3) the O₃-rich air mass from high-altitude regions descended into the urban area following two LLJ events. These conclusions were supported by vertical distributions of O₃ concentrations in the three cases simulated using the WRF-CMAQ model. In addition, the NORHV events resulted in higher initial O₃ concentrations on the following day compared to normal days, exacerbating O₃ pollution. The results of this study demonstrate the significant contributions of complex synergistic effects, such as mountain-valley breezes and vertical transport, to the occurrence of NORHV events in basin cities. These findings may be applicable to other basin cities around the world.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"22 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031246","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}

However, this method may not accurately capture the country's specific emission characteristics. To address this, this study aims to derive country-specific CO₂ emission factors for gas fuels, including liquefied petroleum gas (LPG), liquefied gas for vehicles (LGV), natural gas (NG), and liquefied natural gas (LNG), by analyzing fuel samples collected nationwide. A total of 128 LPG samples from 25 regions, 5 LGV samples from 2 regions, 23 NG samples from 11 regions, and 2 LNG samples from 2 regions were analyzed. Emission factors were determined based on gas composition, carbon content, and net calorific value. The uncertainties were calculated to reflect the contributions of all key parameters in the emission factor calculation. The results show that LPG has the highest EF Tier 2, while LNG has the lowest. The average country-specific CO₂ emission factors for Indonesia are 65.41 ± 0.67 tCO₂/TJ for LPG, 64.89 ± 0.07 tCO₂/TJ for LGV, 57.64 ± 10.18 tCO₂/TJ for NG, and 57.27 ± 9.50 tCO₂/TJ for LNG. We expect stakeholders to incorporate these EF Tier 2 values into greenhouse gas reporting, enabling more accurate assessments of carbon footprints, supporting evidence-based policymaking, and strengthening Indonesia’s climate action efforts.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"297 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031244","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}

Results indicate that soil with high permeability improved the ARGs abundance through elevating the available nutrients in the soil. The ARGs abundance trend across rice growth stages was consistent in different zones (decreasing at heading, increasing at maturity), with high-permeability soil showing minimal variation. The partial least-squares path model (PLS-PM) revealed that soil available nutrients (e.g., AP and NH₄⁺-N) and potential hosts (e.g., <em>Bradyrhizobium</em> and <em>Serratia</em>) play key roles in driving ARGs dynamics in soils with varying permeability. Meanwhile, increased permeability stabilized ventilation conditions, raising redox potential (Eh) in flooded soils, thus reducing the variation rate of ARGs in soil. This study offers important insights into the dissemination of ARGs in paddy fields across different levels of soil permeability.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"49 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031346","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}

Biological studies also indicated that the pathway where PM induces IS involves several pathological processes. Moreover, exposure to PM can alter the expression of specific microRNAs (miRNAs) and ultimately accelerate the onset of IS by regulating related pathways. However, evidence on the role of miRNAs between PM and IS still needs to be fully elucidated. We used the miRNA sequencing datasets from the GEO (Gene Expression Omnibus) to screen miRNAs associated with IS. A nested case-control study was performed, including all incident ischemic stroke cases during the follow-up period and controls matched by age, sex, and entry seasons. Land use regression (LUR) models were constructed to estimate the levels of PM_2.5 and PM₁₀. The real-time quantitative PCR (RT-qPCR) assay was applied to detect the expression of candidate miRNAs in plasma samples collected at baseline to verify whether candidate miRNAs differentially expressed between cases and controls. Mediation analyses were applied to evaluate whether PM could induce IS by affecting the expression of miRNAs. We screened 23 miRNAs expressed differentially between cases and controls from the GEO database. A total of 605 incident ischemic stroke patients were finally included in the case group, and 605 healthy controls were matched. The RT-qPCR assay detected 15 differentially expressed miRNAs. Mediating effects of hsa-miR-107, hsa-miR-320b, hsa-miR-423-5p, hsa-miR-483-5p, and hsa-miR-935 were observed for the associations between PM and IS, indicating that PM could promote IS by altering the expression of those miRNAs. In this nested case-control study, PM might induce IS by affecting the expression of hsa-miR-107, hsa-miR-320b, hsa-miR-423-5p, hsa-miR-483-5p and hsa-miR-935.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"47 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031243","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}

However, a systematic study of microalgae EPS responses and their adsorption behaviors, characteristics, and mechanisms under different heavy metal exposures has not been performed. In this study, EPS extracted from <em>Chlamydomonas reinhardtii</em> CC-125 was analyzed for compositional changes (monosaccharides and proteins) under Cd, Cu, Pb, and Zn treatments. The EPS adsorption capacities and mechanisms for the four metal ions were also investigated. Cd (10 mg/L), Cu (5 mg/L), and Zn (5 mg/L) exposure induced changes in the microalgal EPS composition and structure, and a protein/polysaccharide ratio of greater than 1 was found. This result indicated the crucial role of proteins in stress resistance. In contrast, Pb stress resulted in an increase of 532.64% and 117.48% in proteins and polysaccharides, respectively, with galactose and glucose playing key roles in this process. A fluorescence analysis revealed that Cd/Pb exposure reduced the tryptophan and tyrosine levels in the EPS, while Cu/Zn only weakened tryptophan. As a biosorbent, the adsorption capacity of the EPS for the four metals followed the order of Pb &gt; Cd &gt; Cu &gt; Zn. The fluorescence quenching titration results revealed that fluorescent compounds in the EPS had the strongest complexation ability with Pb (log<em>K</em>_<em>SV</em>: 8.16 × 10³), followed by Cu (log<em>K</em>_<em>SV</em>: 1.79 × 10³), while their abilities for Cd and Zn were weaker. A spectroscopic analysis indicated that the primary functional groups involved in EPS binding with Pb/Cd and Cd/Zn were protein carboxyl groups (C=O/O-C=O) and glycosidic bonds (C-OH/C-O-C), respectively. This study elucidates the response strategies and adsorption mechanisms of the <em>C. reinhardtii</em> EPS to different metals and provides a basis for environmental heavy metal pollution bioremediation.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"2 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031247","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}

UOC presence in biosolids (a wastewater treatment byproduct), which are applied to soil for different reasons raises environmental and health risk concerns. In this study, two multi-class extraction methods were developed and validated to target 111 UOCs from 8 different major families simultaneously in biosolids and biosolids-impacted soil. One method (M-SPE) is a modified version of EPA 1694, that uses triple solid-liquid extraction and solid phase extraction (SPE). The second method (EMR) is a super-fast method consisting in a single solvent extraction and EMR (enhanced matrix removal)-Lipid dispersive SPE. M-SPE performed better overall with 72 and 54 UOCs extracted with 50-130% recovery for soil and biosolids, respectively, compared to EMR for which only 49 and 43 UOCs achieved within the same range, respectively. EMR performed particularly well for the extraction of low concentration opioids from biosolids. The use of ENVI-Carb as an additional cleanup step and its potential to sorb analytes was also evaluated. Although &gt; 75% sorption of 27 UOCs occurred, ENVI-Carb (graphitized carbon) was needed to sufficiently clean extracts prior to injection to avoid precipitation and protect analytical systems. Application of these methods to environmental samples resulted in detection of some flame retardants, opioids, pharmaceuticals, PCPs and phthalates totaling 29 and 22 UOCs in biosolids and soil historically applied with biosolids, respectively. This methodology will be an asset to determining UOC concentrations in biosolids and biosolids-impacted soils.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"74 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026364","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}

Gestational PFAS exposure can adversely affect offspring, yet individual and cumulative impacts of PFAS on the placental epigenome remain underexplored. Here, we conducted an epigenome-wide association study (EWAS) to examine the relationships between placental PFAS levels and DNA methylation in a cohort of mother-infant dyads in Arkansas (N=151). We measured 17 PFAS in human placental tissues and quantified placental DNA methylation levels via the Illumina EPIC Microarray. We tested for differential DNA methylation with individual PFAS, and with mixtures of multiple PFAS. Our results demonstrated that numerous epigenetic loci were perturbed by PFAS, with PFHxS exhibiting the most abundant effects. Mixture analyses suggested cumulative effects of PFOA and PFOS, while PFHxS may act more independently. We additionally explored whether sex-specific effects may be present and concluded that future large studies should explicitly test for sex-specific effects. The genes that are annotated to our PFAS-associated epigenetic loci are primarily involved in growth processes and cardiometabolic health, while some genes are involved in neurodevelopment. These findings shed light on how prenatal PFAS exposures affect birth outcomes and children's health, emphasizing the importance of understanding PFAS mechanisms in the in-utero environment.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"11 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020122","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}

In this study, the flow of NH₃ within air pollution control devices (APCDs) were investigated basing on material flow analysis with in-situ measurements of NH₃ concentrations at the inlets and outlets of each APCD. Then, by combing emission factors updated with recent in-situ measurements and provincial-level activity data from statistical yearbooks and associated reports, NH₃ emissions from various industrial sources, as well as their spatial distribution across China in 2020, were evaluated. It was estimated that, on average, over 70% of NH₃ at APCD inlets is captured by fly ash, about 25% adheres to the inner walls and desulfurization slurry, and less than 5% is directly emitted. The captured filterable NH₃ is later released during subsequent treatment processes, contributing 34.48% to the NH₃ entering APCDs. In total, 38.82% of the NH₃ entering APCDs is ultimately emitted as gaseous NH₃, in which direct and indirect emission accounts for 11.26%and 88.74%, respectively. In 2020, the industrial NH₃ emissions in China were calculated to be 268.02 × 10⁴ t, constituting about 21.19% of total anthropogenic NH₃ emission, and nearly 3-10 times higher than previous estimations in current bottom-up inventories. Flue gas denitrification accounts for the majority (∼60%) of the industrial emission. Regional distribution demonstrates significant spatial variations, with North, East, Central and South China having the highest emission intensities, generally exceed 0.60 t·km^-2·a^-1, more than twice the national average. This study suggests that industrial NH₃ emissions may play a more critical role in air pollution than previously expected, and underscores the importance to reassess the industrial NH₃ emission in China as well as its environmental impacts.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"62 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026371","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}
