Silicone wristbands have been used as effective personal passive sampling tools for semivolatile organic compounds (SVOCs) and serve as integrated measures of inhalation and dermal exposures. However, to-date, translating SVOC concentrations in wristbands to estimated doses has been a gap for their application in exposure assessment. Here, we utilized wristbands as proxy measures for skin-surface lipids to calculate estimated daily intakes (EDIs) from the dermal absorption pathway. EDIs were compared to dermal uptake estimates previously calculated from indoor air measurements and hand wipes, which were collected from residents of both polychlorinated biphenyl (PCB)-contaminated and noncontaminated buildings. Wristband-based estimates showed strong agreement with those from air and hand wipes (rs > 0.8, p < 0.0001), particularly for lower chlorinated PCBs, with dermal uptake accounting for a third of exposed residents’ PCB exposure (∑7PCB = 29.2 ng/kg bodyweight/day). All three dermal estimates were significantly associated with serum measurements among the lower chlorinated congeners. Our results demonstrate wristbands’ potential for quantifying personal external exposure, building on their utility for ranking internal dose. This study further presents a method for using wristbands to calculate dermal absorption for personalized exposure assessment.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 5","pages":"524–529 524–529"},"PeriodicalIF":8.9,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.5c00346","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934317","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}

Traditional assessments require highly trained personnel, are cost- and time-ineffective and produce subjective, qualitative results susceptible to bias. Automated digital histology aims to address these challenges while relieving the burden on pathologists and increasing the meaningfulness and reproducibility of findings. Over the past few years, technological advances in image recognition facilitated the analysis of content-dense histological images for human health. Herein, we applied such advancements to environmental science, and automated digital histology was tested for the identification of lesions (steatosis, melano-macrophage aggregates, leucocyte infiltration, and granuloma) in livers from two fish species (Gadus morhua and Limanda limanda) sampled near oil and gas platforms. Images scored by professional histopathologists were used to train a machine learning model on hematoxylin and eosin-stained whole slide images. The automated digital detections corresponded well with traditional assessments (between 85% and 95%) but required less expertise and were faster. Our results demonstrate a viable path toward a complete, automated workflow for fast, cost-effective and accurate digital histology analysis of environmental and ecotoxicology samples. Efficient, accessible digital histology models will advance understanding of ongoing environmental changes and enhance future preparedness.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 5","pages":"518–523 518–523"},"PeriodicalIF":8.9,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.5c00295","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933631","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}

Here, by mixing dry air into an aerosol flow reactor, we examine whether droplet evaporation may affect wildfire BrC by studying the aqueous nitration of catechol by HONO and darkening of the soluble component of wood smoke. Using online aethalometry and offline UV–vis analysis of particle filter extracts, we observe for the catechol/HONO system that droplet evaporation leads to significantly increased mass absorption coefficients and enhanced ratios of visible to UV absorption compared to bulk solutions, consistent with offline mass spectrometric analysis of dried particles that indicates aromatic nitration and oligomer formation. Differences between the aethalometer and UV–vis filter measurements are attributed to reactions on the dry filter that enhance BrC formation. Evaporation of wood smoke extract droplets also leads to darkening reactions but much less significantly than with catechol/HONO, as expected if only a select fraction of the wood smoke molecules react via concentration enhancement. These findings underscore droplet evaporation/drying as important to BrC atmospheric evolution and suggest that dryer usage may affect particle composition in field measurements.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 5","pages":"619–625 619–625"},"PeriodicalIF":8.9,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

In this study, we systematically examine the key factors─supporting electrolyte composition, charging voltage, and discharging voltage─that impact boron removal performance in both setups, with the insights provided aiding both process optimization and full-scale application. Our results indicate that, while the BPM-assisted system operates at a relatively lower cell voltage and consumes approximately 67% the amount of the energy used by the AEM-assisted system, the requirement for additional salt for sufficient conductivity and water dissociation is impractical for removal of boron from the RO permeate. Furthermore, due to the high cost of BPMs, the overall operational cost of the BPM-assisted system is ∼5-fold higher than that of the AEM-assisted system. Our results further show that applying a reverse potential (−1 V) during discharge desorbs only ∼60–65% of the boron, suggesting that electrode/membrane replacement is needed to maintain activity. Overall, while membrane-assisted electrosorption shows promise for boron removal from RO permeate, significant advancements are needed for both configurations to improve boron removal rates, reduce electrode and membrane costs, and decrease energy demands.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 5","pages":"677–683 677–683"},"PeriodicalIF":8.9,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
