This study examines the combined effects of ocean acidification (OA), ocean warming (OW), and microplastics (MP) loaded with chlorpyrifos (CPF), a broad-spectrum organophosphate insecticide, on sea urchin larvae, evaluating growth and molecular endpoints. Experimental treatments simulated future ocean conditions predicted for 2100, exposing larvae to varying temperature and pH levels, alongside CPF-contaminated MP. RNA sequencing (RNA-seq) was utilized to assess gene expression changes, revealing significant transcriptional shifts in metabolic, cellular, and developmental pathways. Morphological responses showed reduced larval growth, exacerbated under OA and OW conditions. Molecular analyses identified key upregulated pathways associated with stress response, including nitrogen metabolism and extracellular matrix remodelling, while downregulated genes involved DNA stability, cell cycle regulation, and enzymatic activities. These findings suggest a dual compensatory and deleterious response to combined stressors. Notably, temperature acted as a modulator of stressor effects, amplifying oxidative stress and metabolic costs at higher temperatures. Potential biomarkers, such as genes involved in actin regulation and embryonic development, were identified, offering possible tools for early detection of environmental stress. This study highlights the compounded impacts of anthropogenic and climate-induced stressors on marine invertebrates, emphasizing the need for integrative molecular approaches in ecotoxicology.

To determine these mechanisms without relying on animal models and inter-species extrapolation, physiologically relevant human in vitro models are promising tools. We sought to investigate the oxidative stress and inflammatory responses to TDAP in a co-culture model of the human lung. Additionally, we aimed to examine the variability arising from different exposure days and across primary human in vitro models from different donors. Therefore, primary human bronchial epithelial cultures from three donors, each combined with primary alveolar macrophages, were exposed to a continuous flow of ambient TDAP from a high-traffic street in Düsseldorf, Germany on three consecutive days. A versatile aerosol concentration enrichment system was used to increase the fine particulate matter levels from 8 to 42 μg/cm² to 54-143 μg/cm². Gene expression of four oxidative stress markers and four inflammatory cytokines was analyzed by quantitative reverse transcriptase PCR. Compared to incubator controls, even low airflow itself induced the expression of the oxidative stress marker heme oxygenase 1 and the cytokines interleukin 8 and tumor necrosis factor alpha. TDAP exposure, compared to clean air controls, upregulated interleukin 6 in one of the three co-cultures. Because TDAP exposure had minimal effects, exposure day-specific responses could not be discerned. In four of twelve genes, we observe exposure-independet donor differences. Transcriptomic analysis suggested TDAP-induced differential expression of four lung disease-related genes which, however, could not be confirmed by qRT-PCR. Higher TDAP concentrations or repeated exposures may be required to detect robust effects in this system. Our findings highlight inter-donor variability, underscoring the need for larger donor panels. Future studies should also minimize background effects from airflow to enhance model reliability for real-time TDAP exposure studies.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"122399"},"PeriodicalIF":7.7,"publicationDate":"2025-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144774428","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}

We prepared coal gangue-based backfill material (SGBS-PsFs) using industrial solid waste carbide slag to activate coal gangue powder and slag, to which polypropylene fibers (PP) and silica fume (SF) were introduced for synergistic enhancement. The workability, uniaxial compressive strength (UCS), splitting tensile strength (STS), and peak strain of the SGBS-PsFs were then analyzed using macroscopic tests. Digital image correlation and super depth microscopy were used to investigate the damage mechanism and three-dimensional state of the fracture surfaces. Various microscopic techniques were also used to characterize the material. The results indicate that the incorporation of PP and SF was negatively correlated with the flowability of the SGBS-PsFs. In addition, excessive addition affected the material's workability. The synergistic use of PP and SF significantly enhanced the UCS, STS, and peak strain by 37.94 %, 42.26 %, and 47.17 %, respectively. Notably, PP more effectively improved the STS, whereas SF enhanced the UCS. The synergy between PP and SF promoted the material's transition from tensile failure to a combined tensile-shear failure mode, increased the number of damage cracks, and enhanced the roughness of the fracture surfaces. Microscopic analyses indicate that SF optimized the density and pore structure of the SGBS-PsFs matrix, increased the C-S-H gel content, and improved interfacial bonding and stress transfer between PP and the matrix. The combined use of PP and SF exhibited a coupling effect.
