However, to date, an efficient approach for identifying these factors has not been established. To address this limitation, two approaches were utilized to find studies that contained susceptibility information using methylmercury (MeHg) developmental neurotoxicity (DNT) as a case study. Both approaches start with a comprehensive literature search of 5 databases on MeHg followed by keyword filtering for potential epidemiology studies; however, the approaches diverged for the subsequent steps. Approach 1 initially included screening of all 7,531 studies captured by the human filter, but was modified when it was determined that 96% of studies found to include susceptibility information were captured by a dose–response filter. Approach 2 developed a susceptibility filter to limit the screening needed.</div><div>Approach 1 resulted in the identification of 172 studies with information on MeHg DNT susceptibility. Approach 2 reduced screening by 52%, but only captured 74% of PECO-relevant studies when applied to the final study set. Although Approach 2 reduced screening by 12% compared with the use of the dose–response filter in Approach 1, the decreased detection of relevant studies precludes its use in most cases. Expected technological advances that allow refinement of a susceptibility filter to improve performance would be advantageous because of the potential further reduction in screening burden. However, at this time, Approach 1, involving the application of a dose–response filter, is currently recommended for identifying epidemiology papers with information on susceptibility factors.</div></div>","PeriodicalId":308,"journal":{"name":"Environment International","volume":"197 ","pages":"Article 109331"},"PeriodicalIF":10.3,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418220","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 conceptual framework of the Social Exposome extends initial concepts by considering the entirety of societal, social, built and natural environmental exposures which are assumed to holistically impact development and health across the lifecourse. The aim of this study is the identification and characterisation of exposome clusters. Additionally, their relevance for mental health is investigated. To this end 2,850 participants aged 11–12 of the Amsterdam Born Children and their Development (ABCD) Cohort Study were analysed. The exposome was characterized by 60 variables representing the societal, social, built and natural environment. Uniform manifold approximation and projection (UMAP) was applied for dimensionality reduction, and subsequently clustering was performed on the retrieved low-dimensional embedding. Mental health symptoms and behaviour related outcomes were assessed by the Strength and Difficulties Questionnaire (SDQ) as well as the Substance Use Risk Profile Scale (SURPS). The results suggest that exposome clusters are mainly driven by contextual socioeconomic and physical characteristics such as neighborhood income and deprivation rather than social characteristics at the individual level. Moreover, prevalence of children’s mental health problems was more prominent within exposome clusters characterized at the contextual level by more deprived neighborhoods and at the individual level by higher prevalence of maternal mental health problems. This exploratory exposome cluster identification emphasized the relevance of socioeconomic neighborhood characteristics, thus structural inequalities.</div></div>","PeriodicalId":308,"journal":{"name":"Environment International","volume":"197 ","pages":"Article 109335"},"PeriodicalIF":10.3,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418217","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}

Mitigating O₃ pollution in Southeast Asia has become important and urgent. While the nonlinear O₃ chemistry makes policy-making complicated, the O₃ formation regime and O₃ response to different emissions have rarely been assessed in Southeast Asia. Furthermore, the O₃-attributable health impacts in Southeast Asia under future emission scenarios have yet to be quantified. Herein, we applied the regional chemical transport model with the High-order Decoupled Direct Method (HDDM) to simulate the O₃ sensitivity to precursor emissions in Southeast Asia, and then projected the health benefits under future Shared Socioeconomic Pathways (SSP) emission scenarios, providing policy suggestions for mitigating O₃ pollution and its health impacts. Our results show O₃ in urban areas (i.e., Singapore, Jakarta, Kuala Lumpur, Bangkok, and Ho Chi Minh City) was sensitive to both nitrogen oxides (NO_x) and volatile organic compounds (VOCs) emissions, and synergistic NO_x and VOCs control is thus essential. Suburban, rural, and sea areas were under a NO_x-limited regime, suggesting the high effectiveness of controlling NO_x over these areas. Compared with the health impacts in baseline year (2019), the annual total O₃-attributed premature mortality under the business-as-usual emission scenario (SSP245) is projected to reduce by 22 k (47 %) by 2050 due to the future NO_x emission reductions in power generation, industrial process, and transportation. Most of the health benefits will happen in Indonesia, Philippines, Vietnam, and Thailand. The sustainable emission scenario (SSP126) is projected to avoid 36 k annual O₃-attributed premature mortalities by 2050 due to its more stringent NO_x reductions in shipping, transportation, and industrial process. SSP370 and SSP585 are projected to increase the O₃-attributable premature mortality by up to 33 k because of the rising NO_x emissions.</div></div>","PeriodicalId":308,"journal":{"name":"Environment International","volume":"197 ","pages":"Article 109333"},"PeriodicalIF":10.3,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418219","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}

While there have been measurements of airborne PPD-Qs, the size distribution of PPD-Qs and the impact of particle size on PPD transformation chemistry remain largely unknown. Here, through the measurements of atmospheric particles in three megacities in China (Beijing, Xi’an, and Hefei), we find that PPD-Qs are widely distributed in these cities. Further analysis of the size-fractioned particles in Hefei indicates that 48 % of PPD-Qs reside in coarse particles. Given that previous studies mainly focus on the measurement of PPD-Qs in fine particles, the previously reported PPD-Q concentrations and the corresponding human exposure dosages are likely to be significantly underestimated. Furthermore, the ratio of PPD-Q to PPD concentration (PPD-Q/PPD) for particles with size range of 0.056 − 0.1 μm is up to 3 times higher than that with size range of 10 − 18 μm, highlighting the key role of particle size in determining the atmospheric oxidation reactivity of PPDs. Model simulations reveal a size-dependent pattern for the estimated concentration of particulate PPD-Qs in human body.

In <em>in vitro</em> study, PAHs exposure promoted aryl hydrocarbon receptor (AhR) activation, and then directly or indirectly inhibited SIRT6 expression leading to telomere dysfunction, which further caused DNA damage and subsequently promoted endothelial cells senescence.
