Natural Biopolymer Nanofibrils as Sustainable Filter Materials

Advanced Sustainable Systems, Journal Year: 2025, Volume and Issue: unknown

Published: March 7, 2025

Abstract Increasingly serious environmental problems, including air pollution and water contamination, have led to an increasing demand for filter materials (FMs). Biopolymer nanofibrils assembled by natural macromolecules such as polysaccharides or proteins exist widely nanobuilding blocks in materials. Owing the advantages of abundant source, biodegradability, biocompatibility, high specific surface area excellent mechanical properties, biopolymer show bright prospects sustainable functional filters. This review summarizes structure preparation methods representative (cellulose nanofibrils, chitin silk nanofibrils), then outlines their emerging applications field FMs. Finally, existing challenges future opportunities this are summarized.

Physical Health Symptoms and Perceptions of Air Quality among Residents of Smoke-Damaged Homes from a Wildland Urban Interface Fire

ACS ES&T Air, Journal Year: 2024, Volume and Issue: 2(1), P. 13 - 23

Published: Dec. 23, 2024

The Marshall Fire was a wildland urban interface (WUI) fire that destroyed more than 1000 structures in two communities Colorado. High winds carried smoke and ash into an unknown number of buildings that, while not incinerated, were significantly damaged. We aimed to understand whether or damage one's home associated with physical health impacts the event for people living around zone whose homes completely destroyed. analyzed data collected from participants who responded Wave 1 (six months postfire; N = 642) 2 (one-year 413) Unified Research Survey. used self-reported exposure smells their as measures also created spatial based on proximity structures. Reporting headache statistically all metrics (self-reported proximity), reporting strange taste mouth having within 250 m home. Study findings can inform response planning future WUI fires protect residents smoke-damaged homes.

Chemical Transformations of Infiltrated Wildfire Smoke on Indoor-Relevant Surfaces

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: April 17, 2025

Indoor environments are affected during wildfire events due to the infiltration of smoke. In this study, fate smoke, including gases and particles, on indoor surfaces was investigated through laboratory field experiments. Fresh smoke generated from burning ponderosa pine woodchips, which produced well-established biomass tracers, such as levoglucosan, 3-methyl-1,2,3-butanetricarboxylic acid (MBTCA), 5-hydroxymethylfurfural. The interactions particles were observed different indoor-relevant building material surfaces, glass (windows), rutile (paint self-cleaning surfaces), kaolinite (cement proxy clay). However, relative abundance surface-bound species varied depending nature these suggesting that preferential adsorption volatile particle deposition onto relevant play a key role in chemistry air quality following intrusion. Kaolinite particular, exhibited formation surface-initiated products fresh exposure. Furthermore, larger surface ozone-aged exposure, potentially resulting interaction secondary organic aerosol formed ozonolysis. Overall, study demonstrates interact uniquely with compounds, leading distinct chemical transformations.
