Characteristics, sources and potential ecological risk of atmospheric microplastics in Lhasa city

Environmental Geochemistry and Health, Journal Year: 2024, Volume and Issue: 46(9)

Published: July 29, 2024

Atmospheric microplastics are important contributors to environmental contamination in aquatic and terrestrial systems pose potential ecological risks. However, studies on atmospheric still limited urban regions of the Tibetan Plateau, a sentinel region for climate change under warming climate. In this study, occurrence risk were investigated samples suspended collected Lhasa city during New Year February 2023. The results show that average abundance was 7.15 ± 2.46 MPs m

Occurrence and characterization of microplastics in bottled drinking water

Discover Environment, Journal Year: 2024, Volume and Issue: 2(1)

Microplastics (MPs) have been identified in diverse settings, including drinking water, freshwater, food, air, and marine environments. This study employed stereomicroscopic µ-Raman techniques to analyze water samples from ten widely consumed bottled brands, aiming detect characterize MPs. Additionally, the oral consumption of MPs per capita was estimated. The average abundance ranged 9 ± 1.00 MPs/L 3 1.73 across all brands. Various shapes were observed, fibers, fragments, films, pellets, with fibers being predominant (58.928%). categorized by color into five groups (red, blue, black, yellow, transparent), red comprising approximately 35.714% total count. All less than 500 µm size. analysis validated presence eight different polymer types samples, namely Polypropylene (PP) (37.5%), Polymethyl methacrylate (PMMA) (3.571%), polystyrene (PS) (33.928%), polycarbonate (PC) polybutylene1 (PB1) (14.2%), Isotactic polypropylene (iPP) (7.142), Nylone 6-α polymorph (αNY6) (5.357%), polyvinyl alcohol (PVOH) (1.785%). estimated daily intake person determined be 0.42 MPs, translating an annual 153.3 person. origin likely attributed both raw sources packaging materials, underscoring need for further investigation. Given potential health implications human exposure careful consideration should given use plastic potable water.

Less attention has been paid to the pathophysiological changes in atypical asthma such as cough variant (CVA) and chest tightness (CTVA). The obstruction of large small airways is important component development asthma. We investigated whether airway inflammation (SAI) induced dysfunction (SAD) these asthmatics.
