Achieving high-resolution vehicular emission inventories necessitates detailed data on traffic flow, driving patterns, and vehicle speeds for each road network segment. However, in developing countries, the lack of comprehensive traffic data, limited infrastructure, and insufficient monitoring systems constrains the development of high-resolution inventories. This gap poses significant challenges for accurately quantify emissions in regions that often experience rapid urbanisation and traffic growth. Here, we propose a novel method to enhance the spatial disaggregation of large-scale vehicular emission inventories. By analysing road-level emissions data from 63 Brazilian municipalities, we developed a model that predicts weighting factors to disaggregate vehicular emissions into a gridded format, based on the proportion of primary road lengths. Our findings indicate that the predicted weighting factors significantly improve the spatial disaggregation of vehicular emissions compared to the traditional road density method by reasonably increasing the emissions in high vehicular activity areas. This approach not only provides more accurate representations of vehicular emissions for urban planning in Brazil but also offers a solution that can be adapted to enhance top-down vehicular emissions inventories globally. Our study offers a valuable tool that can be tailored to various regions, enabling more precise urban planning and policy-making for air quality management worldwide.</p>","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1-14"},"PeriodicalIF":2.2,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143002627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

This study focuses on the synthesis, characterisation, and application of biodegradable capsules loaded with surfactant for enhanced oil remediation of a clean sand. By controlling the release properties of capsules, the research aims to overcome the limitations of conventional surfactant-based remediation methods, such as rapid washout and reduced efficacy over time. The study outlines a systematic approach, beginning with the synthesis of capsules containing surfactant cargo using the ionic gelation technique, and charactering the capsules' physical attributes. Subsequently, laboratory washing tests were designed to evaluate the efficiency of capsules in enhancing the remediation of oil-contaminated sand, comparing their performance with conventional surfactant application methods. The results show that the capsules enhanced the efficiency of oil removal during the washing process by the controlled release of surfactants. With the use of capsules, oil removal rates of the contaminated sand increased from 29.56% (blank group) to 59.90%, 68.67%, and 76.72% (at 5%, 10%, and 15%, capsule content (mass of capsules by 100 g mass of sand), respectively). Compared to the direct use of surfactants, the capsule approach exhibited higher performance, which increased oil removal efficiency by 95.9%, 97.0%, and approximately 100%, respectively. A release mechanism of higher oil removal ability is proposed based on the measurement of the washing water's surface tension.

Unactivated PS could degrade 14 halogenated hydrocarbons, excluding tetrachloromethane. Unactivated KMnO₄ could degrade chlorinated alkenes.
