Existing studies primarily focus on predicting regional exposure scenarios to assess internal or external exposures risks; however, limited studies have systematically examined the correlation and discrepancies between internal and external exposures. This study collected PAEs samples from three phases (gas, particle, and dust phases) across three representative indoor environments and conducted urinary biomonitoring of phthalate metabolites (mPAEs) among exposed populations. Results showed that PAEs concentrations in the gas phase (21.67 μg·m⁻³) and particle phase (2.38 μg·m⁻³) were significantly higher in laboratories than in dormitories and offices, whereas office desktops exhibited the highest dust phase concentration (312 μg·g⁻¹). Urinary analysis revealed distinct metabolic profiles across populations: MBP was the dominant metabolite in office and dormitory groups (median: 19.3 ng·mL⁻¹ and 10.4 ng·mL⁻¹, respectively), while MMP prevailed in laboratory populations (median: 18.3 ng·mL⁻¹). Seasonal variation analysis indicated that urinary mPAEs concentrations were 4.28 times higher in summer than in winter. Demographic analysis showed that mPAEs levels were higher in males, individuals with obesity, and those with frequent plastic use compared to females, individuals with normal BMI, and those with infrequent plastic use. Furthermore, external exposure estimated from ambient PAEs concentrations exceeded internal exposure derived from urinary mPAEs concentrations by 17.3 %. These findings provide critical insights into exposure pathway differentiation and risk assessment optimization for indoor PAEs contamination.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"38 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Thus, we investigate whether chemicals extracted from polyurethane (PUR) and polyvinyl chloride (PVC) plastics disrupt circadian rhythms via agonism of A₁R. We confirm that plastic chemicals in both plastics activate A₁R and inhibit intracellular cAMP in U2OS cells. Notably, this inhibition is comparable to that induced by the highly specific A₁R agonist 2′-MeCCPA. To assess circadian disruption, we quantify temporal expression patterns of the clock genes PER2 and CRY2 at 4-h intervals over 48 h. Here, exposure to plastic chemicals shifts the phase in the oscillatory expression cycles of both clock genes by 9–17 min. Importantly, these effects are dose-dependent and reversible when A₁R is inhibited by a pharmacological antagonist. This demonstrates that plastic chemicals can disrupt circadian processes by interfering with A₁R signaling and suggests a novel mechanism by which these and other chemicals may contribute to non-communicable diseases.</div></div>","PeriodicalId":308,"journal":{"name":"Environment International","volume":"198 ","pages":"Article 109422"},"PeriodicalIF":10.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bioaccessibility of most metals varied greatly with sources, while it remained relatively stable across different sizes for each source.

The <em>in vitro</em> results demonstrated that 0.34–49.87% of OPEs and 0.80–2.95% of their metabolites (mOPEs) penetrated the skin.

However, the potential impact and mechanism of action of TPHP on adipose tissue are still unclear. This study investigates the potential impact of TPHP on lipid metabolism disorders through <em>in vivo</em> and <em>in vitro</em> experiments. Male and female BALB/c mice were exposed to TPHP (0, 1, 10, and 150 mg/kg/day) for 60 days, and 3 T3-L1 preadipocytes were treated with concentrations of TPHP (0, 0.1, 1, 10 μM) during differentiation. The results showed that exposure to TPHP could cause gender specific dyslipidemia, with male mice exhibiting dose-dependent increases in inguinal adipose tissue coefficient, adipocyte hypertrophy, and upregulation of adipose differentiation and adipogenesis-related genes. In contrast, female mice did not show significant changes in tissue morphology. This suggested that TPHP might promote the potential occurrence of adiposity by disrupting the lipid metabolism homeostasis of male adipose tissue. During the differentiation and maturation process of 3 T3-L1 preadipocytes, exposure to TPHP led to increased lipid accumulation and disrupted lipid homeostasis by simultaneous activation adipogenesis and lipolysis. Multiple omics data showed that the activation of the peroxisome proliferator-activated receptor γ (PPARγ) signaling pathway and fatty acid metabolism was the core mechanism of TPHP induced metabolic dysfunction. Further research showed that TPHP activated the PI3K/AKT pathway, and PI3K inhibitor (LY294002) could rescue TPHP induced lipid droplet formation and normalize the expression of adipogenic markers. These findings confirm that TPHP is a potential environmental obesogen that can disrupt the metabolic homeostasis of white adipose tissue through the PPARγ and PI3K/AKT signaling pathways, with higher susceptibility in males. This study provides compelling evidence for the obesogenic effects of TPHP and information for risk assessment of organophosphorus flame retardants.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"73 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

An assessment framework and the MSSL-RealFormer classification model of ADs wastewater stability were constructed based on physicochemical properties to predict the ADs wastewater stability and the quantitative structure–activity relationship. The constructed MSSL-RealFormer classification model exhibited a markedly higher prediction accuracy than traditional methods. Furthermore, 15 high-stable ADs in wastewater with low biodegradability, high solubility, and low adsorption or partition were identified. SHapley Additive exPlanation method demonstrated that group hydrophobicity, electrostatic and van der Waals forces exerted a significant influence on the ADs wastewater stability. And molecular stability was found to be significantly correlated with the ADs wastewater stability. A combination of density functional theory and MSSL-RealFormer classification model was employed to identify 17 high-stable transformation products of nine medium- and low-stable ADs in wastewater. The Ecological Structure Activity Relationships model demonstrated that bupropion, tapentadol and chlorpheniramine exhibited significant acute toxicity to the aquatic food chain.
