Asthma in older adults is a significant cause of morbidity and mortality, and is increasingly important as life expectancy rises. We investigated the effects of environmental estrogen (EE) exposure on pulmonary inflammatory response in a murine model of older adults. We used our exposure model in old (>18 months) and young (6-8 wk) mice. Bisphenol S (BPS), the most widely used bisphenol A substitute, was administered in drinking water. Cat dander extract (CDE) allergen was given every other day for two weeks. Twenty-four hours after the last nasal application of CDE, the airway hyperresponsiveness (AHR) was analyzed, and bronchoalveolar lavage fluid (BALF), serum, and lung samples were collected. Our model demonstrated that EE exposure promotes AHR in older mice but not in young mice. Baseline numbers of total leukocytes and neutrophils in old mice were significantly higher than those of young mice. Lung histology shows increased cellular infiltration in EE-exposed/allergen-sensitized mice, with higher percentages of severity scores in older mice than in young mice. These findings indicate increased sensitivity to EE exposure and allergen sensitization in older adults. Further investigation into the mechanisms underlying these differential responses is necessary.","PeriodicalId":53200,"journal":{"name":"Journal of Environmental Science and Health Part C-Toxicology and Carcinogenesis","volume":" ","pages":"1-19"},"PeriodicalIF":5.0,"publicationDate":"2026-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149166714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Even so, the evidence base was limited by heterogeneity in design, indirect exposure assessment, and substantial risk of bias. Overall certainty of evidence was very low.

An organ-specific risk perspective is integrated, emphasizing respiratory, digestive, immune, and systemic effects, as well as particle size, polymer type, exposure concentration, and human dose-response uncertainty.

This review highlights how NPs alter gut microbiota composition, suppressing beneficial microbes while fostering opportunistic pathogens and how such imbalances may contribute to human health issues.

This systematic review aims to compile current in vivo evidence from mouse studies to assess how PS-MP/NP exposure influences gut microbial diversity, taxonomic composition, microbial metabolites, and subsequent physiological outcomes. A PRISMA-guided literature search identified 15 controlled mouse studies published between 2010 and 2024. Across these studies, PS exposure consistently induced gut dysbiosis, characterized by reductions or shifts in alpha-diversity, distinct beta-diversity clustering, loss of beneficial commensals such as Lactobacillus, Bifidobacterium, and members of Ruminococcaceae, and enrichment of opportunistic or pro-inflammatory taxa including Proteobacteria, Helicobacter, and Staphylococcus. Notably, MNPs particles induced more pronounced microbial disruption than micro-sized forms. Overall, current experimental evidence indicates that PS-MPs/PS-NPs induce multidimensional toxicity by simultaneously disrupting gut microbial ecology and host metabolic pathways.

Among these, polycyclic aromatic hydrocarbons and heavy metals are of particular importance, as numerous compounds within these categories are classified as carcinogenic by the International Agency for Research on Cancer (IARC). It is crucial to understand the mechanistic basis of their genotoxicity to elucidate how environmental exposures contribute to genotoxicity. In this regard, biochemical, cytogenetic, and DNA integrity biomarkers have become essential tools for detecting biological responses and unraveling toxicodynamic pathways. Despite these advancements, most existing evidence derives from studies assessing single compounds; however, real-world exposures typically involve complex mixtures in which polycyclic aromatic hydrocarbons and heavy metals frequently co-exist. Mixtures can produce interaction effects (synergistic, additive, or antagonistic) that significantly alter the extent and nature of genotoxic damage. Therefore, risk assessments based solely on isolated exposures may not adequately reflect environmentally relevant scenarios and could underestimate potential hazards. Overcoming this limitation necessitates research strategies that incorporate validated biomarkers to evaluate combined exposures. These methods improve understanding of interaction mechanisms, quantify mixture-induced DNA damage, and clarify individual roles of pollutants, enhancing human health risk assessment.","PeriodicalId":53200,"journal":{"name":"Journal of Environmental Science and Health Part C-Toxicology and Carcinogenesis","volume":" ","pages":"160-197"},"PeriodicalIF":5.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147724545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
