Plant-Based Biomonitoring of Airborne Microplastics: A Systematic Review
AI summary Read the abstract
Tiny plastic particles floating in the air we breathe are becoming a bigger concern, but tracking them with current equipment is expensive and doesn't cover much ground. This review pulls together existing studies to show that plants, like leaves and moss, can act as natural air filters that trap these microplastics, making them a cheap, low-tech way to monitor pollution over time and across wider areas. Better tracking of airborne microplastics matters because it's a first step toward understanding how much of this pollution we're actually exposed to and what it might mean for our health.
Background Airborne microplastics (AMPs) are recognized as atmospheric pollutants. Traditional monitoring methods provide limited spatial and temporal resolution. Plants may offer an alternative for evaluating atmospheric microplastic deposition. Despite this potential, a review synth...

Potential Role of Mosses in Evaluating Airborne Microplastic Deposition in Terrestrial Ecosystems
AI summary Read the abstract
This review examines the potential of mosses to serve as cost-effective biomonitors for tracking airborne microplastic deposition in terrestrial ecosystems. Preliminary studies indicate that mosses accumulate higher concentrations of microplastics than lichens, likely due to their physical structure. The study outlines steps needed to develop a standardized, reliable methodology for using mosses to monitor airborne microplastic pollution across both inhabited and remote regions.
Moss as a biomonitor for the atmospheric deposition of anthropogenic microfibres
AI summary Read the abstract
Researchers used moss (Bryophyta) as a passive biomonitor to track atmospheric deposition of anthropogenic microfibres, finding that moss samples from various locations accumulated synthetic fibres reflecting local sources of airborne plastic contamination. The study establishes moss monitoring as a practical method for assessing microplastic atmospheric deposition without active collection equipment.
Moss Bags as Biomonitors of Atmospheric Microplastic Deposition in Urban Environments
AI summary Read the abstract
Researchers tested moss bags as a biomonitoring tool for measuring atmospheric microplastic deposition across an urban gradient in southern Ontario, Canada. They found that moss bags effectively captured microplastics, with higher deposition in more urbanized areas. The study demonstrates that moss-based monitoring is a practical, low-cost method for tracking airborne microplastic pollution in cities.
