Examining the key decision criteria centering around data choices, selection of input variables, methodological approaches, and theoretical conceptualizations are integral to progressing toward hazard-specific and place-specific vulnerability assessment. Moreover, decisions touching on Geographic Information Science (GIScience)-related issues (e.g., the implications of scale choices and accounting for contextual effects) impact how people who are at risk for adverse heat-health outcomes are represented. In turn, these representations influence how critical interventions are implemented. Given the prospects of increases in adverse heat-health outcomes associated with planetary and urban warming, it is crucial to examine how the representation of heat vulnerability can be enhanced for tailored interventions.OBJECTIVEThis commentary examines the assumptions underpinning the decision criteria for heat vulnerability analysis and identifies associated implications while recommending priority future research. Reorienting general hazard conceptualizations to reflect contextual, heat-specific nuances is crucial for attenuating heat-related health outcomes.DISCUSSIONHeat vulnerability studies lack consistent decision criteria, which undermines progress toward hazard-specific and place-specific vulnerability relevance. Some of these limitations are attributable to the persistent application of general, all-hazards conceptualizations to hazard-specific studies. Moreover, inconsistent decision criteria undermine the replicability and validity of studies and propagate uncertainty while compromising progress toward standardized, consistent, scalable approaches, and testing of existing assumptions that could strengthen heat vulnerability theory. Given GIScience technologies are central to representing spatial patterns of vulnerability, the epistemological foundation of vulnerability theory can be strengthened when GIScience concepts (e.g., the operational scale of social-environmental determinants of health and assumptions underpinning spatial relationships) are considered during vulnerability representation.CONCLUSIONExamining decision criteria for heat vulnerability assessment is crucial to identifying optimal sets of heat-specific and place-specific risk indicators, thereby enhancing the representation of vulnerability. https://doi.org/10.1289/EHP14801.","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":"42 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841124","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}

Recently marketed ultrasonic cigarettes (u-cigarettes) claim to be less harmful than e-cigarettes that use heating coils.OBJECTIVESWe quantified chemical elements/metals in multiple flavors of SURGE u-cigarettes, JUUL e-cigarettes, and \"Other Brands\" of pod-style e-cigarettes.METHODSElements/metals were identified in atomizers of SURGE using a scanning electron microscope/energy-dispersive X-ray spectrometer. Quantitation of elements/metals in fluids and aerosols from SURGE, JUUL and Other Brands was performed using inductively coupled plasma optical emission spectroscopy.RESULTSU-cigarettes contained a sonicator, unlike e-cigarettes which had heated coils. Sixteen elements were identified in at least one fluid or aerosol sample. Generally, u-cigarette fluids and aerosols had more elements/metals at higher concentrations than aerosols from 4th generation e-cigarettes. Element concentrations generally increased in fluids after vaping. All products, including SURGE, had silicon in their fluids and aerosols. Nickel, which was present in low concentrations in all fluids except KWIT Stick (up to 66,050 μg/mL), transferred to the aerosols with low efficiency. SURGE, but not e-cigarettes, also had copper and zinc in their fluids, but little transferred to their aerosols. SURGE fluids and aerosols, unlike e-cigarettes, had relatively high concentrations of arsenic and selenium. Arsenic and selenium, which are on the FDA's Harmful and Potentially Harmful List, likely came from poor quality solvents used to produce the e-liquids in SURGE pods and possibly from the sonicator, which heats during use.DISCUSSIONSURGE u-cigarettes produce aerosols with metals equivalent to heated coil-style e-cigarettes and had high levels of arsenic and selenium, which are a health concern. Regulations limiting arsenic and selenium in these products are needed, and routine surveillance to identify rogue products, such as Kwit Stick, that have abnormally high levels of nickel or other metals could protect human health. https://doi.org/10.1289/EHP15648.","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":"60 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819345","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}

Both are considered environmental carcinogens with evidence of thyroid function disruption, reported associations with thyroid cancer in adults, and concerns of distributive inequity. O-ALAN may also serve as a proxy for other outdoor air pollutants or urbanization.METHODSWe conducted a case-control study of papillary thyroid cancer nested within a California birth cohort that included 736 cases diagnosed at 0-19 years and born in 1982-2011 and 36,800 controls frequency-matched on birth year. We assigned individual-level exposures for residence at birth for ambient PM2.5 concentrations from a validated, ensemble-based prediction model and O-ALAN using the New World Atlas of Artificial Night Sky Brightness. We calculated odds ratios (OR) and 95% confidence intervals (CI) using logistic regression adjusting for potential confounders and stratified by age and race/ethnicity.RESULTSWe observed statistically significant associations between PM2.5 exposure and papillary thyroid cancer risk overall (OR per 10-µg/m3 increase in PM2.5=1.07, 95%CI: 1.01-1.14), among the 15-19 year age group (OR=1.08; 95%CI: 1.00-1.16), and among Hispanic children (OR=1.13; 95%CI: 1.02-1.24). For O-ALAN, we observed statistically significantly increased odds of papillary thyroid cancer in higher exposure tertiles compared to the reference tertile in the overall population (tertile 2: OR=1.25, 95%CI 1.04-1.50; tertile 3: OR=1.23, 95%CI: 1.02-1.50) and when modeled as a continuous variable (OR 1.07 per 1 mcd/m2).

Consequently, there are increasing public health concerns that substantial effects mediated by synthetic chemicals may impact human health. Recently, epidemiology studies reported associations between bisphenol exposure and non-alcoholic fatty liver disease (MASLD). However, the causal relationship and the molecular mechanisms affecting hepatocellular functions are still unknown.OBJECTIVESOur study aimed to understand the molecular mechanism by which BPS exposure caused hepatic lipid deposition.METHODSC57BL/6J mice were exposed to BPS for three months and its effects were assessed by histology. RNA sequencing (RNA-seq), Assay for Transposase Accessible Chromatin with high throughout sequencing (ATAC-seq) and Cleavage Under Targets and Tagmentation (CUT&Tag) were used to investigate mechanistic details. ATF3 liver-specific knock out mice and cells were used to validate its functions in BPS induced hepatotoxicity.RESULTSHere, mice that were chronically exposed to BPS showed significant lipid deposition in liver and dyslipidemia, and were predisposed to MASLD, accompanied with reprogrammed liver transcriptional network and chromatin accessibility that were enriched for Atf3 binding motif. Comparing to the control group, we identified numerous differential Atf3 binding sites associated with signaling pathways integral to lipid catabolism and synthesis in BPS exposure group, resulting in a drastic surge in lipid accumulation. Moreover, knocking out Atf3 in vitro and in vivo significantly attenuates BPS-induced hepatic lipid accumulation via the regulation of chromatin accessibility and gene expression. Besides, inhibiting the JunB also eliminates the BPS-induced Atf3 upregulation and lipid accumulation.CONCLUSIONOur study reveals a novel mechanism, through which BPS upregulates JunB and Atf3 to impair hepatic lipid metabolism and provides new insights into the hepatotoxicity of BPS.. https://doi.org/10.1289/EHP17057.","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":"35 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819045","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}
