To assess whether EVs can reduce summertime air pollution exposure inequalities in the Atlanta metropolitan area, we conduct high-resolution (1 km) photochemical air quality simulations using the Community Multiscale Air Quality (CMAQ) model. A 30% EV adoption of heavy-duty and light-duty vehicles is simulated to evaluate changes in nitrogen dioxide (NO<sub>2</sub>), maximum daily 8-hr average ozone (MDA8 O<sub>3</sub>), and fine particulate matter (PM<sub>2.5</sub>) during summer. EV adoption leads to average domain-wide concentration reductions of 0.22 ppb in NO<sub>2</sub>, 0.94 ppb in MDA8 O<sub>3</sub>, and 0.06 μg/m<sup>3</sup> in PM<sub>2.5</sub>, with localized increases in NO<sub>2</sub> and PM<sub>2.5</sub> near power plants from increased electricity demand. The primary driver of air quality improvement from EV adoption is the reduction in on-road vehicle emissions, which outweighs any increases in emissions from electric generating units. The largest exposure reductions are observed in communities with higher proportions of Asian, Hispanic, and Black populations, underscoring the potential for EV adoption to alleviate exposure burdens in the communities of color. However, exposure disparities persist even with EV adoption, despite overall reductions in exposure levels across all racial/ethnic groups. Coarse-resolution (12 km) simulations tend to underestimate exposure for minority groups by up to 25% for NO<sub>2</sub> and 10% for PM<sub>2</sub><sub>.5</sub> but still capture the overall patterns of exposure disparities.</p>","PeriodicalId":48618,"journal":{"name":"Geohealth","volume":"10 9","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13602988/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149041491","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}

This study quantified the relationship between heat-related illness and multiple dimensions of greenspace morphology using an 8-year (2016–2023) unbalanced panel data set comprising 19,021 block-group–year observations across 2,427 census block groups in Arizona, USA. One meter high-resolution National Agricultural Imagery Program aerial imagery was classified to calculate greenspace percentage, number of greenspaces, average size, shape complexity, connectedness, and distantness, at the block group level. We applied conditional spatial autoregressive models with a negative binomial distribution to estimate associations between each morphology metric and yearly heat-related illness counts, adjusting for sociodemographic and geographic covariates. Additional sensitivity analyses evaluated the robustness of findings to overall greenspace amount, local climatic conditions, and alternative exposure specifications. We found higher greenspace percentage, aggregation, shape complexity, connectedness, and density were consistently associated with lower heat-related illness risk. A one–standard deviation increases in shape complexity corresponded to a 12.4% decrease in expected heat-related illness counts (IRR = 0.876, 95% CI: 0.834–0.921).

Temperature, monsoon rainfall and its active-break phases, relative humidity (RH), and the El Niño–Southern Oscillation are identified as key climatic predictors of dengue transmission in the region. Dengue seasonality in Kerala closely follows its rainfall cycle, with cases rising in May and peaking during the southwest monsoon (June–September), reaching a maximum in June–July. To capture the nonlinear and combined relationships between climatic predictors and dengue incidence, several machine learning (ML) models were trained and evaluated, with the XGBoost regression model showing the best predictive performance (<i>R</i><sup>2</sup> = 0.72, Normalized Root Mean Square Error = 0.53). Locally, warmer temperatures (30.5–32.5°C) and moderate humidity (66%–79%) during the pre-monsoon season, together with moderately high rainfall (180–450 mm/month) during the monsoon season, favor high dengue incidence. Remotely, El Niño–like conditions increase dengue incidence by shifting large-scale circulation toward warmer and drier pre-monsoon conditions over Kerala, while La Niña–like conditions have the opposite effect, providing about 3 months of potential predictability. Future simulations from Coupled Model Intercomparison Project Phase 6 models project an increase in dengue incidence by 16%–20% in the near future (2021–2040) and 46%–113% in the far future (2081–2100) under low-to-high emission pathways.

This study evaluates As mobility, bioaccessibility, and associated health risks in 57 agricultural topsoils from seven regions affected by geogenic enrichment and historical mining. Arsenic partitioning was characterized using operationally defined extractions and mineralogical analyses, and bioaccessibility was determined by an in vitro gastric assay. The total As concentrations range from 25 to 2007 mg kg<sup>−1</sup>, exceeding national agricultural soil thresholds (40 mg kg<sup>−1</sup>) in ∼80% of samples. Nevertheless, relative As bioaccessibility ranges from 2% to 38%, with most soils exhibiting values below 10%. Arsenic is predominantly associated with Fe (oxyhydr)oxides, while discrete As-bearing minerals are rare. Surface-bound As, defined by phosphate extraction, strongly controls both mobility and bioaccessibility. Long-term phosphate enrichment due to repeated fertilization exerts contrasting effects on As behavior. Readily soluble P enhances both As mobility and bioaccessibility, whereas higher Olsen-extractable P is associated with lower As bioaccessibility, suggesting progressive occupation of reactive sorption sites. A risk assessment based on a conservative rural ingestion scenario indicates that most soils did not exceed non-carcinogenic thresholds when bioaccessible As was considered. These findings demonstrate that bioaccessible As and associated exposure risk are controlled primarily by reactive surface-bound As fractions rather than by total soil As concentrations, whereas phosphate exerts contrasting secondary effects depending on its geochemical availability and partitioning.</p>","PeriodicalId":48618,"journal":{"name":"Geohealth","volume":"10 9","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13575764/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148978414","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}

Heat stress was assessed using a physiology-based human heat balance model. Results reveal significant inter-individual differences in individually experienced temperatures (IET) and humidities (IEH), with three sub-daily patterns emerging: highest overall exposures, strong diurnal amplitude, and day-long stable exposures. Median IET and IEH were 25.9°C and 1.4 kPa, with maxima reaching 47.5°C and 5.1 kPa. On average, participants experienced temperatures 10.4°C below regional conditions, with low evaporative cooling requirements to attain heat balance for sedentary activities.

Fixed effect models and random forest models were established to scrutinize the impacts and significance of independent variables on aging levels under different urbanization levels. Notably, the aging levels across all urbanization levels rose by a factor of 1.5–2.1 from 2010 to 2020.

Moreover, air pollutants show age-specific associations, and medical resources only have a significant supporting impact on LA85+.
