Here, we aimed to characterize the associations between ambient air pollution and mortality in Chinese populations living in both urban and rural areas, where rural populations have not been studied previously at national level.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;In this nationwide time-stratified case-crossover study, we extracted non-accidental death cases of all ages in both urban and rural areas during 2008–2020 from National Mortality Surveillance System, which covered 40,300 representative township-level administration units from 29 provinces, representing nearly 24 % of Chinese population. The urban-rural classification of participants' addresses was defined based on the China's National Bureau of Statistics. Daily township-level exposures to ambient particulate matter in diameter less than 10 μm and 2.5 μm (PM&lt;sub&gt;10&lt;/sub&gt; and PM&lt;sub&gt;2.5&lt;/sub&gt;), nitrogen dioxide (NO&lt;sub&gt;2&lt;/sub&gt;), carbon monoxide (CO), sulfur dioxide (SO&lt;sub&gt;2&lt;/sub&gt;), and 8-h maximum ozone (O&lt;sub&gt;3&lt;/sub&gt;) were estimated using the Nested Air Quality Prediction Modeling System.

We analyzed 250 24-h urine samples from the German Environmental Specimen Bank (ESB), collected between 2000 and 2021, for exposure to diethylamino hydroxybenzoyl hexyl benzoate (DHHB), a UV filter increasingly used in sunscreens. Three major metabolites were examined: 2-(4-diethylamino)-, 2-(4-ethylamino)-, and 2-(4-amino)-2-hydroxybenzoyl)benzoic acid (DHB, EHB, AHB), with detection rates of 18°%, 13°%, and 87°%, respectively. While EHB and DHB were specific to DHHB, AHB suggested other exposure sources, making it unreliable for assessing DHHB exposure. DHB and EHB were first detected in 2012, with increased detection rates thereafter. The median daily intake of 37 ng/kg bw/d was much lower than the derived no-effect level of 2900 mg/kg bw/d, indicating low risk from DHHB exposure. However, since the analyzed ESB samples were collected in winter, they likely reflect exposure from other products and the environment rather than sunscreen-related exposure. Recently, concerns have emerged regarding the DHHB impurity di-n-hexylphthalate (DnHexP), a reproductive toxicant not authorized in the EU. Retrospective analysis of oral DHHB dosing experiments indeed revealed impurity related dose-dependent excretion of DnHexP metabolites (MnHexP, oxidized 5-OH-MnHexP, and 5-oxo-MnHexP). Due to uncertainties in dose allocation, only a rough excretion fraction of 45°% for MnHexP was derived. Our findings suggest that the DHHB impurity DnHexP may contribute to DnHexP exposure in sunscreen users applying products with contaminated DHHB. Given DnHexP's toxicity, this warrants re-assessment of DHHB's safety in cosmetics and enhanced surveillance of both DHHB and DnHexP in HBM studies.</div></div>","PeriodicalId":13994,"journal":{"name":"International journal of hygiene and environmental health","volume":"266 ","pages":"Article 114565"},"PeriodicalIF":4.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to explore the effects of PFASs exposure on glucose metabolism disorders in older adults. We enrolled 704 elderly individuals aged over 65 years from Wuhan, China. Plasma concentrations of 12 PFASs were measured using liquid chromatography-mass spectrometry. Generalized linear models and quantile-based g computation (qgcomp) were employed to evaluate the effects of individual and combined PFAS exposures on T2D risk. Additionally, a meta-analysis was conducted to consolidate findings reported in the literature for validation purposes. The detection rate of all 12 PFASs exceeded 80%, with median concentrations ranging from 0.01 to 15.22 ng/mL. Single exposure analysis revealed an inverse association between perfluorododecanoic acid (PFDoA) and impaired fasting glucose (IFG), as well as between PFDoA, perfluoroundecanoic acid (PFUdA), perfluorodecanoic acid (PFDA), perfluorononanoic acid (PFNA), and perfluorooctanoic acid (PFOA) and T2D risk (<em>P</em> &lt; 0.05). Quantile-based g-computation analysis showed an inverse association between the PFAS mixture and IFG and T2D risk, although these associations lacked statistical significance. PFDA exhibited the greatest weight in the negative associations with IFG and T2D. Meta-analysis demonstrated an inverse association between PFDA and PFUdA and T2D risk, and PFOA demonstrated an inverted U-shaped nonlinear dose-response relationship with the risk of T2D (<em>P</em><sub>nonlinear</sub> = 0.026). The potential impact of PFAS exposure on glucose metabolism merits attention, underscoring the need for a thorough comprehension of the biological mechanisms underlying PFAS-mediated metabolic effects to facilitate precise risk assessment.</div></div>","PeriodicalId":13994,"journal":{"name":"International journal of hygiene and environmental health","volume":"266 ","pages":"Article 114560"},"PeriodicalIF":4.5,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PFAS concentrations, including perfluorohexane sulfonate (PFHxS), perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), perfluorononanoate (PFNA), and perfluorodecanoate (PFDA), were measured in plasma collected at ∼28 gestational weeks among pregnant women enrolled in the New Hampshire Birth Cohort Study (2009–2018).

We identified BP trajectories using latent class trajectory modeling and evaluated associations between PFAS mixtures and BP trajectories using probit Bayesian kernel machine regression and multinomial quantile g-computation. We used linear mixed models to examine individual PFAS and BP changes during the third trimester. Models were adjusted for sociodemographic, lifestyle, and reproductive factors, and gestational week of blood sample collection. During late pregnancy, plasma PFOS was associated with greater increases in SBP and PFHxS was associated with greater increases in DBP. Over the third trimester, each doubling in plasma PFOS was associated with 0.07 mmHg (95% CI: −0.01, 0.14) increase per week in SBP, and each doubling in plasma PFHxS was associated with 0.07 mmHg (95% CI: 0.02, 0.12) increase per week in DBP.

AMREF Health Africa end-line implemented a Solar for inclusive WASH services project between February 2021 and November 2023. Therefore, this study aimed to compare WASH service delivery indicators at the baseline and endline of implementing the Solar for Inclusive WASH services project.

The study used simple random sampling method when selecting participants in classes and systematic sampling was used in allocation of sample sizes for each school Quantitative data was collected using electronic structured questionnaires and analyzed using STATA version 14. Descriptive statistics were derived from the data collected. Research Approval was obtained from Mildmay Uganda Research Ethics Committee (MUREC) and Uganda National Council for Science and Technology (UNCST). Data collection for both the baseline and endline evaluation was conducted in the 6 similar target schools where project interventions were conducted.</div></div><div><h3>Results</h3><div>At the end-line, the round-trip distance from the classroom to the point of water collection was reduced to less than 200 m and the turnaround time spent was reduced to less than 5 min for the majority of respondents. With the analysis of Paired sample T-test, the p-value (Sig.) for each of the two variables (turnaround time and distance travelled) of 0.000 is less than 0.05 that indicating that the implementation of the solar-powered mini water systems has significantly reduced the turnaround time spent and distance travelled by respondents in search of safe and drinking water while at school. There was a marked improvement in hand washing after defecation from 16.4% at baseline to 85.7% at end-line. Experiences of diarrhoea were reduced by 11.5% and none of the girls missed school due to menstruation at endline. The presence of water in school compound has reduced the practice of the pupils skipping classes during break off (break and lunch) due to search of water. The practice of children carrying water to school for use like drinking is no longer existent. The study reports that there has been a reduction in cases reported for girls undergoing menstruation missing class and resorting to stay at home.</div></div><div><h3>Conclusion</h3><div>There was a significant improvement in access to water, hygiene and sanitation indicators in the schools following the implementation of the Solar for inclusive WASH services project.</div></div>","PeriodicalId":13994,"journal":{"name":"International journal of hygiene and environmental health","volume":"266 ","pages":"Article 114558"},"PeriodicalIF":4.5,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
