Air pollution has become a serious global issue, which has significant impacts on both human health and the environment. Over the past decade, air quality has deteriorated due to various anthropogenic activities including construction, urbanization and industrialization. These activities release hazardous particles and harmful gases into the atmosphere, contributing to poor air quality. Developing countries such as India have been particularly affected, with some of their cities among the most polluted worldwide. To address this serious concern, it is imperative to develop and implement air pollution control technologies for both indoor and outdoor environments. This study focuses on the structured investigation of the performance of locally available air filter media in terms of their removal efficiency for submicron and micron-size particles. Various indigenous air filter media are subjected to rigorous testing to evaluate their overall and size-specific filtration efficiency and corresponding differential pressure drop. The results of these performance evaluations are then compared to their effectiveness in removing coarse and fine particles from the air. This research aims to provide valuable insights into the development of effective air filtration systems to combat air pollution. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Fine particulate matter (PM2.5) emitted from marine transportation, bulk materials handling at the docks, and dust dispersion has garnered increased attention, particularly in the interface between port and urban areas. This study explored the inter-transport of PM2.5 between Kaohsiung Harbor and neighboring Metro Kaohsiung. Chemical analyses of PM2.5 samples from four sites include water-soluble ions, metallic elements, carbons, anhydrosugars, and organic acids to establish PM2.5's chemical fingerprints. The CALPUFF air dispersion model is employed to simulate the spatiotemporal distribution of PM2.5 in Kaohsiung Harbor and adjacent urban areas. A clear seasonal and diurnal variation of PM2.5 concentrations and chemical composition was observed in both harbor and urban areas. The high correlation of nighttime PM2.5 levels between the port and urban areas suggests inter-transport phenomena. Sea salt spray, ship emissions, secondary aerosols, and heavy fuel-oil boilers exhibit higher levels in the port area than in the urban area. In Metro Kaohsiung, mobile sources, fugitive dust, and waste incinerators emerge as major PM2.5 contributors. Furthermore, sea breeze significantly influences PM2.5 dispersion from Kaohsiung Harbor to Metro Kaohsiung, particularly in the afternoon. The average contribution of PM2.5 from ships' main engines in Kaohsiung Harbor ranges from 2.9% to 5.3%, while auxiliary engines contribute 3.8%–8.3% of PM2.5 in Metro Kaohsiung. © 2024 Elsevier Ltd

The last decade epidemiologic concern of drinking water contaminants of emerging concern (CECs) in Asian Countries: A scoping review

引用

Heliyon 2024年第20期10卷 e39236页

作者： Nathanael, Rinaldy Jose Adyanis, Latonia Nur Oginawati, Katharina Environmental Engineering Program Faculty of Science and Technology Airlangga University Surabaya 60115 Indonesia Department of Environmental Engineering Chung Yuan Christian University Taoyuan 320314 Taiwan Environmental Management Technology Research Group Department of Environmental Engineering Faculty of Civil and Environmental Engineering Bandung Institute of Technology Bandung 40132 Indonesia

With the rapid industrialization and urbanization in Asian countries, the challenge of rising emerging contaminants in the environment, including the water cycle, has become more pronounced. Consequently, the presence of CECs in drinking water systems is inevitable due to their ubiquitous nature in aquatic environments. This scoping review aims to identify epidemiological concerns regarding drinking water CECs in Asian countries over the past decade by describing the types of assessed CECs, their associated health effects, and identifying gaps and future research prospects through a summary of relevant studies. Searches were conducted on PubMed and Scopus up to February 29, 2024. Included were epidemiological studies from the past 10 years (since January 2014) in Asian countries that assessed emerging contaminants in drinking water through direct measurement or analysis as factors. From an initial pool of 3198 results, 15 relevant studies were selected. These studies assessed various types of CECs, including disinfection byproducts (n = 10), endocrine disruptors (n = 2), pesticides (n = 2), and a protozoan pathogen (n = 1). The meticulous assessment of CECs and associated health outcomes in Asian epidemiological studies over the past decade has been deemed inadequate to address the wide range of ubiquitous CECs in drinking water and their potential health effects that have not yet been addressed. While not the sole objective, the primary aim of epidemiological studies is to inform policy decisions and increase awareness among the public and policymakers. Therefore, researchers in Asian countries, particularly in environmental and public health fields, should prioritize the development of research in this area by exploring more CECs type and associated health outcomes. © 2024 The Author(s)

In this study, we demonstrate that treating milk using a continuous liquid-phase plasma (CLPD) based process is an effective solution. The effect of different system power (180 W-320 W) and flow rate (30 ml/min-70 ml/min) on the inactivation of Shiga-toxin Producing E. coli (STEC) enriched in pasteurized milk was evaluated. Pasteurized milk without STEC enrichment served as a parallel control. Experiments have shown that CLPD-treated milk exhibits a significant reduction in colony-forming units (CFU) of STEC under majority of treatment conditions based on the two significant operational factors. It has been proven that system power and liquid flow rate significantly impact continuous microbial inactivation in milk. A lower flow rate (30ml/min) and higher system power (300w) result in a notable CFU reduction (6.3 logs), while the higher flow rates with lower system power led to milder changes in STEC reduction in milk. Under strong treatment conditions, the STEC inactivation effect was consistent with low variation. Evaluation of the physicochemical properties of CLPD treated milk revealed lower resultant temperatures compared to conventional pasteurization methods. Scanning Emission Microscopy (SEM) imaging has revealed significant cell disruption of STEC by CLPD processing. These findings offer practical insights into cold plasma treatment of milk, suggesting it as a potential alternative to conventional pasteurization methods. © 2024 ASABE Annual International Meeting.

We describe design and characterization of an aerosol NanoSpotTMcollector, designed for collection of airborne particles on a microscopy substrate for direct electron and optical microscopy, and laser spectroscopy analysis. The collector implements a water-based, laminar-flow, condensation growth technique, followed by impaction onto an optical/electron microscopy substrate or a transmission electron microscopy grid for direct analysis. The compact design employs three parallel growth tubes allowing a sampling flow rate of 1.2 L min−1. Each growth tube consists of three-temperature regions, for controlling the vapor saturation profile and exit dew point. Following the droplet growth, the three streams merge into one flow and a converging nozzle enhances focusing of grown droplets into a tight beam, prior to their final impaction on the warm surface of the collection substrate. Experiments were conducted for the acquisition of the size-dependent collection efficiency and the aerosol concentration effect on the NanoSpotTMcollector. Particles as small as 7 nm were activated and collected on the electron microscopy stub. The collected particle samples were analyzed using electron microscopy and Raman spectroscopy for the acquisition of the particle spatial distribution, the spot sample uniformity, and the analyte concentration. A spot deposit of approximately 0.7-mm diameter is formed for particles over a broad particle diameter range, for effective coupling with microscopic and spectroscopic analysis. Finally, the NanoSpotTMcollector’s analytical measurement sensitivity for laser Raman analysis and counting statistics for fiber count measurement using optical microscopy were calculated and were compared with those of the conventional aerosol sampling *** © 2023 American Association for Aerosol Research

Microbially induced calcite precipitation (MICP) is an emerging geotechnical improvement technology that has received wide attention from researchers around the world. The applications of MICP in geotechnical field including soil improvement, surface resistance from erosion, coastal protection, and slope stabilization have been investigated by previous researchers. This paper presents a review on application of MICP for slope stabilization. Three subtopics were selected to be discussed: application of native bacteria, modified MICP methods, and field-scale studies. This review reveals that (1) MICP has the potential for slope stabilization;(2) native bacteria are ideal for use in MICP for application in slopes located in regions with variable cold climatic conditions;(3) to improve the effectiveness of MICP for slope stability, traditional MICP needs be modified;(4) MICP appears to have the potential to be one of the future landslide mitigation strategies since it works effectively in the field-scale test. Additionally, the recommended further researches in MICP for slope stabilization are: (1) Study on the other types of native bacteria for diverse environmental condition is required;(2) to discover the best slope stabilization method, the combination of MICP and other traditional slope stabilization techniques should be investigated;(3) it is critical to investigate the effectiveness of the MICP technology for slope stabilization under various conditions in the field. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
