This study evaluated the validity of the ECTemp™ algorithm and compared the use of a photoplethysmography-based smartwatch to a chest strap as the heart rate input for the algorithm. <i>Methods.</i> In 102 construction workers during the summer, gastrointestinal temperature was measured via ingestible telemetric pill (<i>T</i> _PILL), and heart rate was measured with a Polar H10 chest strap (<i>n</i> = 102) and a Garmin Instinct 2 smartwatch (<i>n</i> = 60) during a single work shift. Peak, mean and continuous time-series data from each device were used to compute core temperature estimates using ECTemp™ (ECTemp_GARMIN and ECTemp_POLAR). Agreement was evaluated with Bland-Altman analyses, Pearson correlations, and Kendall's Tau correlations. <i>Results.</i> Compared to T_PILL, ECTemp_POLAR showed a bias of -0.16 ± 0.30 °C for continuous data, with a median Kendall's τ of 0.39. ECTemp_GARMIN showed a bias of -0.09 °± 0.28 °C (median <i>τ</i> = 0.36).

Prior studies of TCs and birth outcomes often examined single storms or single TC characteristics (e.g. maximum wind speed) and rarely assessed urban/rural differences. To better understand TC impacts on perinatal health, we evaluated associations between multiple TC exposure metrics and several adverse birth outcomes and considered urban-rural variations. We conducted a population-based time series analysis of 2436 478 singleton births in Georgia from 2000-2018, in which individual-level state birth records were aggregated to the county-week level and linked to weekly, county-level TC data from the National Oceanic and Atmospheric Administration and the National Aeronautics and Space Administration. TC exposure metrics included maximum sustained wind speed (>17, 22, 25 m s^-1), cumulative rainfall (>125, 150, 175 mm), storm proximity (<5, 10, 20 km), and flooding events (yes/no). Generalized linear models with a Poisson distribution were used to estimate relative risks (RRs) and 95% confidence intervals (CIs) for weekly rates of preterm birth (PTB, <37 weeks), low birthweight (LBW, <2500 g), small-for-gestational-age (SGA, <10th percentile), and proportion of male births.

To better understand the utility of low-cost air sensors and portable air filtration devices as household-level interventions for improving indoor air quality (IAQ) during WFS events, we launched a participatory science study among select King County, Washington households during summer 2023 and 2024, coinciding with wildfire season. Participants received indoor PurpleAir sensors, do-it-yourself (DIY) box fan filter kits, high efficiency particulate air (HEPA) portable air cleaners, and surveys on device use. We compared hourly fine particulate matter (PM_2.5) concentrations from the indoor sensors to those from proximate outdoor PurpleAir sensors. We ran linear mixed-effects models to assess the influence of WFS and building characteristics on IAQ and to evaluate the efficacy of air filtration use (2024 only). Twelve households in 2023 and 24 households in 2024 completed the study. In 2023, the mean indoor and outdoor PM_2.5 concentrations were higher than those in 2024 (a difference of 2.62 <i>µ</i>g m^-3 and 1.74 <i>µ</i>g m^-3, respectively), reflecting different trends in air quality and WFS events. In 2024, both filtration devices were associated with reductions in indoor PM_2.5 concentrations; however, effect estimates differed after accounting for outdoor PM_2.5, with HEPA portable air cleaners associated with a greater reduction than DIY box fan filters. The occurrence of a WFS event, warmer outdoor temperature, and higher appraised household value were significantly associated with higher indoor PM_2.5 concentrations, although a large portion of the model's variance remained unexplained.

For children in cities, urban schools present numerous advantages in education quality and access to resources and opportunities that stimulate learning and improve health.

Yet, little is known about environmental conditions in schools and schoolchildren's health in rapidly urbanizing SSA cities. This paper describes the various datasets captured within the Accra School Health and Environment Study (ASHES), a study platform designed to characterize air and noise pollution at elementary schools and for schoolchildren, and their influence on key markers of childhood health and development.

ASHES was implemented in Accra, one of the fastest growing metropolises in SSA. Between July 2022 and May 2023, 1,037 children (∼60% female) aged 8-12 were recruited from 90 public (74%) and private primary schools.

This review synthesizes findings from studies on phytoremediation and assisted phytoremediation in lead-zinc mining regions worldwide. Phytostabilization was the dominant process, with Pb largely immobilized in the roots and showing minimal movement through the plant. In contrast, Zn showed higher mobility, allowing for occasional phytoextraction. Pioneer shrubs and xerophytic grasses effectively stabilized nutrient-poor, metal-rich soils in Mediterranean and North African sites, while deep-rooted woody plants restricted contaminant migration through root immobilization. Genuine hyperaccumulators were rare, suggesting that local metal tolerance rather than hyperaccumulation is the dominant adaptive mechanism. Assisted systems enhanced remediation efficiency: arbuscular mycorrhizal fungi (AMF) and earthworms improved fertility and reduced Pb and Zn mobility, whereas plant growth–promoting rhizobacteria (PGPR) and endophytes stimulated growth but had variable effects on metal mobility. Biochar consistently decreased Pb, Zn, and Cd bioavailability, improved soil pH and nutrient status, and supported vegetation, though its effectiveness depended on feedstock and dose. In conclusion, phytostabilization using tolerant native vegetation, supplemented by microbial or biochar amendments, represents the most reliable and sustainable remediation pathway in lead-zinc mining areas, whereas phytoextraction remains restricted to specific Zn tolerant species.","PeriodicalId":48496,"journal":{"name":"Environmental Research Communications","volume":"7 11","pages":"112002-112002"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147881737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
