Abstract

This study investigates the concentrations of atmospheric aerosol particles (PM, including PM2.5 and PM10), as well as the presence and distribution of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in ambient air in Bien Hoa City (Dong Nai province, Vietnam) during the dry and rainy seasons in 2023. The concentrations of 7 PCDDs and 10 PCDFs congeners in PM10 or PM2.5 were determined using gas chromatography-mass spectrometry (GC-MS). The results show that the concentration of PM10 and PM2.5 were 54.7 ± 9.4 µg/m3, 65.3 ± 7.6 µg/m3, and 39.6 ± 7.9 µg/m3, 58.9 ± 12.6 µg/m3, in the rainy season and dry season, respectively. This reveals that while only PM2.5 concentration levels in the dry seasonexceed national ambient air quality standards, but all of PM2.5 concentration levels consistently exceeded WHO guidelines. The study highlights the dominance of PM2.5 and its adverse health implications, as evidenced by the PM2.5/PM10 ratio (0.74 and 0.85 for the rainy and dry seasons, respectively) and its association with worse air quality. Analysis of PCDD/Fs concentrations in PM samples demonstrates their comparable levels in both seasons, with OCDD being the most abundant species. Furthermore, the study estimates the toxic equivalency (TEQ) of PCDD/Fs and assesses health risks, revealing a potentially high cancer risk from exposure to these pollutants, particularly PM2.5 under WHO2005-TEQ. Several PCDD/Fs- WHO2005-TEQ congeners exhibit higher concentration levels in PM2.5 compared to PM10, suggesting differential particulate matter dynamics and potential environmental implications. These findings underscore the urgent need for mitigation strategies to alleviate air pollution and reduce associated health risks in the dioxin hotspot of Vietnam.

Abstract

This study aims to thoroughly investigate the linguistic impact of emojis and emoticons in modern written communication. This work attempts to shed light on these digital symbols’ linguistic structure, social implications, and evolution through a multidisciplinary research method. A mixed-methods approach was used in the research, integrating interdisciplinary viewpoints with quantitative and qualitative analyses. A vast amount of data was gathered from various digital communication channels, such as email exchanges, messaging apps, and social media. A sizable collection of text messages with emojis and emoticons was assembled. Emotional cons and emojis were categorized using linguistic analysis, breaking down their structure into visual components and repeating patterns. Their grammatical and syntactic effects on written language were also evaluated in this investigation. The findings indicate that using emojis in writing positively correlates with emotional expressiveness. This implies that when people wish to express emotions and subtlety in their messages, they typically utilize more emoticons. They enhance digital etiquette, reduce misunderstandings, improve emotional connection, and foster cross-cultural understanding. Emoticons are a global visual language that helps people communicate, create empathy, and navigate digital communication.
