Biomonitoring of Yozgat Çamlık National Park’s (Türkiye) Anthropogenic Microfiber Pollution: A Comprehensive Analysis of Lichen-Supported Air Quality Assessment and Microplastic Composition Insights
Summary
Researchers used lichens collected from three zones with varying human activity in Yozgat Çamlık National Park, Turkey, as bioindicators of atmospheric microfiber pollution. Anthropogenic microfibers—predominantly synthetic textiles—were found in all samples, with higher counts in areas closer to roads and human settlements, validating lichen biomonitoring as a tool for airborne microplastic assessment.
Aim of study: To evaluate lichens as bioindicators of atmospheric microfiber pollution by measuring anthropogenic microfiber levels in samples from Yozgat Çamlık National Park (Türkiye). Area of study: Three regions with varying human activity were sampled within the park. Material and method: Anthropogenic microfibers were analyzed using wet peroxide oxidation and Rose Bengal staining. Their size and color were determined via stereomicroscopy, and polymer types were identified by FT-IR and Raman spectroscopy. Main results: Blue was the predominant color, and fiber sizes ranged from 0.15–4.2 mm. The main polymers were polyurethane (42%), acrylonitrile butadiene styrene (25%), and polyethylene terephthalate (13%). Research highlights: Lichens effectively indicate atmospheric microfiber deposition and reflect regional variations linked to human activity.

Lichen Biomonitoring of Airborne Microplastics in Milan (N Italy)
Researchers used lichen transplants across Milan to monitor airborne microplastic deposition, finding that microplastic accumulation varied with land-use zones and traffic density, validating lichens as effective biomonitors for atmospheric plastic pollution.
Passive biomonitoring of airborne microplastics using lichens: A comparison between urban, natural and protected environments
Researchers used lichens as natural air pollution monitors and found that microplastics accumulate in lichen tissue along a gradient from natural areas to city centers, with urban sites in Rome showing twice the contamination of natural sites. Over 97% of the trapped particles were fibers, and the study also documented the first evidence of larger mesoplastic pieces caught by lichens -- confirming that airborne plastic pollution increases with human activity.
Comparison of Lichen and Moss Transplants for Monitoring the Deposition of Airborne Microfibers
Researchers compared lichen and moss transplants as tools for monitoring airborne microfiber pollution across urban sites in Italy. They found that lichens accumulated significantly more microfibers than mosses and were better at detecting differences between locations. The study suggests that lichen transplants offer a more effective and accessible biomonitoring approach for tracking airborne microplastic contamination in cities.
Microplastics in Lichen Thalli: A Photo or a Movie of Local Atmospheric Deposition?
Microplastics were found in lichen thalli collected from various sites, making lichens useful bioindicators for monitoring local and temporal patterns of atmospheric microplastic deposition. The study shows that lichens passively accumulate airborne plastics and can provide a record of pollution over time.
