Fine particulate matter (PM_2.5) from wildfire smoke contributes to cardiorespiratory morbidity and mortality, adverse birth outcomes, mental health stressors, and disruptions to food security and traditional livelihoods. However, quantifying health risks remains difficult due to sparse monitoring, challenges in isolating wildfire-specific pollution, and limited long-term exposure assessments. We developed a historical air quality dataset for Alaska using a hybrid approach that integrates GEOS-Chem atmospheric modeling with ground-based data to estimate daily wildfire-attributable PM_2.5 at a 0.625° × 0.5° resolution from 2003 to 2020. We aggregated these estimates by census tract and derived metrics to quantify long-term wildfire smoke exposure, then combined these estimates with social vulnerability data to identify populations disproportionately affected. Alaskans experienced an average of 3.5 million person-days of moderate and >800 000 person-days of dense smoke exposure annually. In years when over 2 million acres burned, 86%-98% of census tracts recorded at least 1 d of moderate smoke, and up to 73% experienced dense smoke. Northern Interior Alaska had over 300 cumulative days of poor air quality (∼10% of summer days) over the 18 year period, with smoke waves lasting as long as 43 d. Tracts identified as having high smoke exposure and high smoke vulnerability were generally in rural Interior Alaska; however, urban tracts in Interior and Southcentral were also identified. High-exposure census tracts had statistically greater proportions of housing cost-burdened residents and women of childbearing age. This study highlights the need to move beyond traditional fire metrics and adopt measures that better capture the full scope of human exposure.

Our random-effects meta analysis analyzed estimated the pooled relative risk (RR) at the 80th summer temperature percentile compared to the reference temperature (10th percentile) across the ZIP codes. Our meta-regressions analyzed how the ZIP code-specific relative risks (RRs) differ by the number of parks, sum of park areas, percentage of vegetated area, percentage of recreational vegetated area, vegetation density (30 m), percent tree coverage, and percent street-level tree coverage aggregated at the ZIP code level. A total of 1075 959 counts of violent crime were included in our analysis. We found 8% (95% CI: 7%-10%) higher risk of violent crime incidents when the daily mean temperature was at the 80th percentile (25.9 °C) compared to the reference temperature (8.6 °C). The pooled RR was significantly lower in ZIP codes with the highest vegetation density (RR = 1.085 [95% CI: 1.040-1.131]) compared to those with the lowest vegetated density (RR = 1.124 [1.088-1.162]).

Compared with β -lactam and sulfonamide antibiotics, tetracycline and quinolone antibiotics have longer environmental half-lives and are more widely used, particularly in agriculture, aquaculture, and healthcare. In this study, the composition, spatial distribution, potential sources, and ecological risks of 4 tetracycline and 20 quinolone antibiotics were systematically investigated by liquid chromatography tandem mass spectrometry (LC-MS/MS) in the surface seawater of the Northeastern Indian Ocean for the first time. A total of nine antibiotics were detected in seawater samples, including tetracycline (detection rate: 100%), oxytetracycline (100%), chlortetracycline (100%), doxycycline (100%), ofloxacin (100%), ciprofloxacin (100%), norfloxacin (92.3%), enrofloxacin (96.2%), and fleroxacin (23.1%). Tetracycline, oxytetracycline, chlortetracycline, doxycycline, ofloxacin, ciprofloxacin, norfloxacin, and enrofloxacin were widely distributed throughout the study area, with tetracycline antibiotics (83.8%) being significantly more prevalent than quinolone antibiotics. Among them, oxytetracycline was the dominant tetracycline antibiotic. The concentrations of tetracycline and quinolone antibiotics ranged from 0.258 to 23.521 ng l −1 (mean: 16.813 ng l −1 ) and 0.016–9.480 ng l −1 (mean: 3.261 ng l −1 ), respectively. The highest concentrations were found in the northeastern region of the study area. Aquaculture and livestock farming in Myanmar, Thailand, and Malaysia were identified as potential sources of these antibiotics. Ecological risk assessments indicated that ciprofloxacin poses a moderate risk to aquatic organisms in the Northeastern Indian Ocean. This study provides new insights into antibiotic pollution in the open waters of the Indian Ocean and highlights the urgent need for further research on the ecological impacts of these emerging pollutants in marine environments.","PeriodicalId":11747,"journal":{"name":"Environmental Research Letters","volume":"20 7","pages":"074070-074070"},"PeriodicalIF":0.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
