Antarctic Science, Год журнала: 2025, Номер unknown, С. 1 - 13

Опубликована: Фев. 24, 2025

Abstract This work provides a comprehensive examination of microplastic air pollution in Antarctica. Due to atmospheric microplastics’ emerging importance, analytical procedures and health effects are discussed. Microplastic poses an increasing threat the unique delicate Antarctic ecosystem, potentially triggering harmful consequences not only for local ecosystem fauna, but also human well-being, given severe implications global scenarios such as imminent worldwide warming melting polar ice. Numerous investigations have now exposed extent prevalence both nano- microplastics this region, significant storehouse planet’s freshwater. highlights challenges assessing hazards that microplastics, particularly nanoscale variants, may pose life maintenance. The results suggest mechanisms mitigation critical transportation reaches. overview better understanding Antarctica while highlighting urgency more research area elucidate precisely short-, medium- long-term arrival these contaminants Antarctic.

Exploring Microplastic Distribution in Western North American Snow

Journal of Hazardous Materials, Год журнала: 2024, Номер 480, С. 136126 - 136126

Microplastic (MP) transport in the atmosphere, one of least studied environmental compartments because relatively small size air-borne MPs and challenges identifying them, may be inferred from their occurrence snowfall. In this study, 11 sites across western coastal North America were sampled analyzed for MP presence fresh snowfall, months-old summer surface snow, stratified deposits snow pits. detected characterized using a method integrating linear array µ-Fourier Transform Spectroscopy (µFTIR) batch spectral analysis with open-source platform Open Specy. Recovery rate sample filtration to data was conducted, field or laboratory blanks suggested negligible contamination (≤ 1 polyamide fragment per blank). Concentrations snowfall remote those proximal sources 5.1-150.8 p/L 104.5-325 snowmelt water, respectively. Summer that several months old had concentrations ranging 57.5-539 meltwater, at different depths within snowpack 35-914 p/L. Our results demonstrate streamlined used measuring pristine environments, contributing better understanding long-range transport.

Effect of microplastics on the allelopathic effects of native and invasive plants on co-occurring invaders

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Introduction Microplastic pollution has emerged as a significant global change factor, with the potential to alter biological, physicochemical properties of soil and subsequently affect plant growth. Despite growing recognition impacts microplastic pollution, mechanisms by which microplastics modify leaf chemistry influence allelopathic interactions among co-existing species remain unclear. Methods We used native perennial forb Achyranthes bidentata invasive annual Amaranthus spinosus focal species. grew two without competition each other. This setup was further combined treatment involving addition polyethylene (PE). then testd effects aqueous extract on seed germination seedling growth for five Subsequently, metabolomic analysis conducted extracts, in were observed test Results discussion The presence PE enhanced biomass both under competitive non-competitive conditions. Furthermore, found induce negative effect co-occurring plants, appeared be mediated through changes chemistry. Bisdemethoxycurcumin, ethylparaben, salicin 6’-sulfate 5-hydroxy-3’,4’,7-trimethoxyflavone glucoside proven important compounds enhancement. Overall, these results suggest that capability co-existence plants altering their potential. insight into between allelopathy provides novel perspective how could ecosystem dynamics. Future studies aim answer might root exudates whether this process would mediate biological invasion.
