While horizontal diffusion depends on larger-scale hydrodynamics, vertical settling responds strongly to particle properties and local conditions. In natural waters, salinity changes and the presence of suspended sediments are two key factors that alter settling behavior. Therefore, developing a targeted predictive model to quantify their combined effects is essential for elucidating the mechanisms of microplastic vertical transport. In this study, we selected five typical microplastic polymers to conduct laboratory settling experiments. We systematically investigated the individual and combined influences of salinity gradients and suspended sediments on MP settling characteristics. Based on the results, we modified the standard settling velocity equation by adding a salinity correction coefficient (K_s) and a sediment interaction coefficient (K_m). This gave us a coupled salinity-sediment correction model. When tested against experimental data from freshwater, saline, and sediment-laden conditions, the model performed well, with high goodness-of-fit values that confirm its reliability and broad applicability.

Auditory effects of exposure, including declines in hearing function and associated underlying noise-induced injury, have been extensively documented. Affecting many millions worldwide, auditory consequences of noise exposure interfere with communication, isolating individuals from family, friends, and co-workers, and exacerbate functional declines with age. Due to an increasing number of mechanistic and epidemiological cohort studies, the past twenty years have seen a shift from skepticism that noise could affect non-auditory health, to increasing evidence for effects on cardiometabolic disease, annoyance, sleep disturbance, mental health, dementia, and children's learning.

Since epigenetic age was first described over a decade ago, it has been used as an exposure or an outcome in biomedical research to address the fundamental question of \"aging\". Yet, a critical question remains unresolved: how epigenetic age mediates the effects of exposures on health outcomes. Mediation analysis provides a rigorous statistical framework for decomposing total effects into direct and indirect pathways, thereby testing the extent to which epigenetic age deviation explains exposure-outcome relationships. Meanwhile, the reporting quality using mediation analysis varied across studies. This scoping review provides a methodological primer on causal mediation analysis and a literature review using epigenetic age as a mediator with quality assessment. We conducted an initial literature search through four online databases (PubMed, Embase, MEDLINE, and CINAHL) at the beginning of September 2025. We identified 22 studies (published since 2022) examining epigenetic aging as a mediator between environmental/lifestyle exposures and health outcomes. Most studies used blood-based DNA methylation and applied causal mediation frameworks. GrimAge, PhenoAge, and DunedinPACE were more frequently used. Outcomes primarily included mortality and cardiovascular disease, while exposures covered smoking, diet, socioeconomic factors, clinical biomarkers, and environmental pollutants. Although causal mediation analysis suggested that epigenetic aging could be a possible mechanistic mediator linking exposures to disease risk, many studies lacked methodological rigor. To enhance epigenetic evaluation in broad settings, further work should apply causal mediation analysis to epigenetic aging markers with a rigorous methodology.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"124600"},"PeriodicalIF":7.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147809120","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 compared start-up strategies via high-nitrogen-loading gradient adaptation versus low-nitrogen-loading environmental acclimation in integrated fixed-film activated sludge - up-flow anaerobic sludge blanket (IFAS-UASB) reactors inoculated with mature Anammox sludge, evaluating their effects on system performance and microbial communities. High-loading start-up markedly enhanced process activation, stimulated extracellular polymeric substance (EPS) secretion, and achieved a maximum total-nitrogen removal efficiency of 80.0%. Performance remained stable at approximately 65% even after stepwise reduction of the influent nitrogen concentration, exceeding the approximately 40% efficiency under low-loading conditions. Microbial analyses further indicated that high loading enriched anammox bacteria (AnAOB) (e.g., Candidatus Brocadia and Candidatus Jettenia) and fostered positive interactions with associated taxa, forming a cooperative metabolic network. In contrast, low-loading systems were dominated by denitrifiers, with AnAOB declining sharply due to competitive exclusion. Carrier type showed limited influence.

Here, we conceptualize HAT impacts as a multifaceted process that includes both direct effects and indirect effects mediated through HAT-induced increases in ambient air pollution, notably ozone, and their interactions. We developed a unified epidemiologic framework of mediation, interaction, and exposure measurement error, and estimated the total effect (TE) of HAT on mortality. Using national mortality and environmental data from South Korea, we projected HAT-related mortality from 2025 to 2100 under demographic and mitigation/adaptation scenarios, which includes the direct effect of HAT and indirect effect of HAT (through HAT-mediated ozone) and the interaction between HAT and HAT-mediated ozone. Across all scenarios, the interaction between HAT and HAT-mediated ozone contributed to a substantial fraction of HAT-related mortality. Under low mitigation/adaptation scenario, SSP5-RCP8.5, HAT is projected to cause 855,202 deaths (95% CI: 518,447-1,224,610), of which 481,214 deaths (126,493-884,528) are attributable to the interaction between HAT and HAT-mediated ozone, while 335,363 deaths (186,224-522,933) are attributable to the direct effect of HAT alone.

OTC stress can alter the secretion and structural composition of extracellular polymeric substances (EPS) of anammox bacteria, reduce the size of anammox granular sludge (AnGS), and decrease the stability of AnGS.

The relative abundances of OTC resistance genes, tetG and tetX, decreased in the PE MPs group, while they increased in the OTC group and the combined stress group.

These contaminants can bioaccumulate in exposed organisms and induce oxidative stress, cellular damage, reproductive impairments, and embryonic alterations. In viviparous species like the critically endangered Spiny butterfly ray (Gymnura altavela), maternal transfer is a relevant but still underexplored contaminant exposure pathway during early development. This study provides the first evidence of maternal transfer of several elements in G. altavela through integrated maternal and embryo tissue and reproductive fluid analyses. Samples were obtained from artisanal fisheries in Rio de Janeiro, southeastern Brazil, elemental determinations were performed employing inductively coupled plasma mass spectrometry (ICP-MS) and oxidative stress biomarkers were investigated by spectrophotometry. Maternal offloading was verified for most determined elements, with accumulation observed in various embryo tissues. Several metals and metalloids were also observed as capable of traversing the blood-brain barrier, suggesting neurotoxicity potential, as well as accumulating in the rectal gland, possibly resulting in osmoregulation alterations. Higher contaminant levels were noted in the left side of the reproductive system, potentially due to ovarian asymmetry and greater embryonic loads in this side. Reproductive and yolk-associated tissues exhibited higher metal and metalloid concentrations when compared to other batoid species, suggesting high local contamination. These findings highlight maternal transfer as a critical exposure route and suggest that pregnant females and their embryos may be significantly affected in contaminated areas.
