“…Consumer firework-related physical injuries can be devastating, leading to permanent vision loss, limb amputations, and, in some cases, death (Puri et al, 2009;Tandom et al, 2012;Turgut et al, 2022). On the other hand, exposure to PM2.5 can cause acute and chronic health problems, as evidence shows that exposure to the particulate is linked to cardiovascular disorders such as heart attacks, heart failure, arrhythmias, and strokes (Krittanawong et al, 2023;Garcia et al, 2023). More critical are the respiratory effects, such as asthma attacks and exacerbated respiratory symptoms like sneezing, wheezing, and shortness of breath, as exposure to PM2.5 is associated with those respiratory disorders (Ren et al, 2017;Cao et al, 2018;Garcia et al, 2023).…”

The high concentrations of particulate matter (PM) in the atmosphere have adverse effects on both the environment and human health, as well as on urban and faunal biodiversity. Short-term events, such as the burning of fireworks, attributable to human activity, result in a significant and rapid increase in PM concentration levels within the atmosphere. We present findings derived from observations made using low-cost PM sensors deployed as part of the Environmental Monitoring Network in Querétaro, Mexico. These sensors utilize the Environmental Geo Monitoring Stations (EMGA) device, developed by the Institute of Geosciences at UNAM. The observation period spanned from December 10, 2023, to January 10, 2024, encompassed the Christmas and New Year holidays, and focused on PM2.5 concentrations, and a comparison with a similar period from February 10, 2024, to March 10, 2024, considered a typical activity period in the area. The results reveal a substantial increase in PM2.5 concentrations over time and spatial distribution during this period, with notable increases observed during the festive season. Specifically, prolonged periods exceeding up to 6 hours were noted on festivities dates. This research offers insight into the effects, trends, and spatial-temporal distribution of pollutants within the city of Queretaro, which may be used as a reference for other cities around the world. Furthermore, a comparison between PM2.5 data recorded by the EMGA devices and infrasound data was conducted complementarity to explore potential correlations between these two types of data.

“…With the rapid development of our energy-driven society, the harm caused to human health by solid particulate matter (PM) pollution has garnered widespread concern. − This is attributed to increased pollutant emissions from human activities such as transportation, , heating, power plants, and industrial processes. Among PM pollutants, fine particles (PM2.5, solid particles with a diameter of 2.5 μm or less) are primarily responsible for PM-related allergies and the spread of respiratory diseases. − Filtering micron and submicron PM is time-consuming, and designing filters with ideal porous nanostructures is complex. , Masks, serving as close-fitting respiratory filtering medical protection equipment, isolate dust, waste gas, pathogenic microorganisms, and viruses. However, these masks, typically made from various plastic polymers and designed for single use, can release microplastics more easily and rapidly than plastic bottles.…”

Self-powered wearable electronic products have rapidly advanced in the fields of sensing and health monitoring, presenting greater challenges for triboelectric materials. The limited surface polarity and structural defects in wood fibers restrict their potential as substitutes for petroleum-based materials. This study used bagasse fiber as the raw material and explored various methods, including functionalizing cellulose nanofibrils (CNFs) with polydopamine (PDA), in situ embedding of silver particles, filtration, and freezedrying. These methods aimed to enhance the triboelectric output, antibacterial properties, and filtration properties of lignocellulosic materials. The Ag/PDA/CNF-based triboelectric nanogenerator (TENG) demonstrated an open-circuit voltage of 211 V and a short-circuit current of 18.1 μA. An aerogel prepared by freeze-drying the Ag/PDA/CNF material, combined with a polyvinylidene fluoride nanofiber structure fabricated by electrospinning, constitutes the TENG unit. A self-powered respiratory detection mask was created using this combination, achieving a filtration efficiency of 94.23% for 0.3 μm particles and an antibacterial rate exceeding 99%. In addition, it effectively responded to respiratory frequency signals of slow breathing, normal breathing, and shortness of breath, with the output electrical signal correlating with the respiratory frequency. This study considerably contributes to advancing wood fiber-based triboelectric materials as alternatives to petroleumderived materials in self-powered wearable electronic products for medical applications.

“…The adverse health effects, including cardiovascular and respiratory diseases and hospital admissions associated with exposure to PM 2.5 , are extensively studied [11,12]. However, much less is known about the health effects of sub-micron particles, which can represent a significant fraction of PM 2.5 .…”

Sub-micron particles are ubiquitous in the indoor environment, especially during wildfire smoke episodes, and have a higher impact on human health than larger particles. Conventional fibrous air filters installed in heating, ventilation, and air conditioning (HVAC) systems play an important role in controlling indoor air quality by removing various air pollutants, including particulate matter (PM). However, it is evident that the removal efficiency of wildfire smoke PM and its effect on filter performance is significantly under-studied. This study delves into the size-specific removal efficiency of pine needle smoke, a representative of wildfire smoke and emissions. We test an array of filter media with minimum efficiency reporting values (MERV) spanning 11–15. Both size-resolved particle number concentrations and mass concentrations were measured using an Optical Particle Sizer (OPS, TSI, Inc.) and a Scanning Mobility Particle Sizer (SMPS, TSI, Inc.). Furthermore, we characterize the filter media morphology and smoke particles deposited on filter fibers using Scanning Electron Microscopy (SEM) to gain insights into the interaction dynamics of these particles. Our findings add to the comprehension of the relationship between MERV designations and smoke removal efficiency. Such insight can inform standards and guidelines and equip decision-makers with the knowledge needed to initiate measures for mitigating the impact of air pollution, specifically on the indoor environment.
