This study measured THg concentrations in maternal venous blood, placental tissue, and cord blood from 111 mother-infant pairs. Overall, THg exposure levels in this population were relatively low; however, pregnant women who consumed home-grown rice exhibited higher Hg concentrations than those who consumed market-purchased rice. After adjusting for covariates, Hg exposure was negatively associated with birth weight Z-score (BWz) and biparietal diameter Z-score (BPDz). Restricted cubic spline analysis further revealed a nonlinear relationship between cord blood THg and BWz, as well as a similar pattern between maternal THg and placental 5-methylcytosine (5mC) levels. Our findings suggest that prenatal Hg exposure may be associated with foetal growth outcomes and placental epigenetic alterations in a population where rice represents an important dietary source of MeHg. Given the cross-sectional design, causal inference is limited, and the findings should be interpreted with caution and not be overgeneralized. Further longitudinal studies in diverse populations are warranted to confirm these associations and clarify underlying mechanisms.</div></div>","PeriodicalId":11775,"journal":{"name":"Environmental toxicology and pharmacology","volume":"127 ","pages":"Article 105174"},"PeriodicalIF":4.6,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149066897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 a rat model, BaP exposure induced dose-dependent hepatic injury and oxidative stress. Mechanistically, BaP activated the NF-κB/TNF-α signaling axis, upregulating ICAM-1 and initiating NLRP3 inflammasome assembly. Activated NLRP3 promoted Caspase-1-dependent cleavage of GSDMD, leading to hepatocyte pyroptosis and the release of IL-1β and IL-18. Concurrently, ICAM-1 facilitated inflammatory cell infiltration. This sustained inflammatory microenvironment ultimately activated the TGF-β/α-SMA/Col-I axis, driving hepatic stellate cell activation and excessive extracellular matrix deposition, thereby promoting liver fibrosis.

However, their sublethal effects on wildlife populations and ecosystem stability remain significantly underexplored. Laboratory studies have demonstrated that mycotoxins induce epigenetic toxicity, but the implications of these molecular findings for populations and ecosystems are not yet fully understood. This review synthesizes current knowledge regarding mycotoxin-induced epigenetic modifications and evaluates their effects across multiple levels of biological organization. Mycotoxins can induce intergenerational effects in model organisms, but true transgenerational inheritance remains less established in mammals. These heritable epigenetic modifications could propagate from individuals to populations, potentially affecting food webs, biodiversity, and ecosystem services, although these outcomes remain largely hypothetical. To address these knowledge gaps, we propose an epigenetics-informed risk assessment framework that incorporates early-warning epigenetic biomarkers, accounts for both intergenerational and transgenerational effects, integrates multi-stressor interactions, and evaluates ecosystem-level responses under climate change scenarios. Implementing this framework will depend on field-deployable detection methods, enzyme-based bioremediation strategies, and climate-adaptive management under a One Health approach. This review highlights the urgent need for interdisciplinary collaboration to address mycotoxin-induced epigenetic damage, which poses a potential threat to ecosystem integrity.
