Recent Trends and Future Challenges for Lichen Biomonitoring in Forests

This review examines recent trends in using epiphytic lichens as biomonitors in forest ecosystems, which have historically been underrepresented compared to urban and industrial monitoring. Researchers discuss how lichens respond to air pollution and climate change in forested areas and identify future challenges for expanding lichen biomonitoring programs in these environments.

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.

Lichens and Microplastics

This review explored the relationship between lichens and microplastics, discussing both lichens' potential as biomonitors of environmental MP contamination and their secondary metabolites' possible interactions with plastic particles. The authors suggest lichens as underutilized bioindicators for atmospheric and terrestrial microplastic 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.

Selecting the species to be used in lichen transplant surveys of air pollution in Tunisia

Researchers evaluated four lichen species for suitability as air pollution biomonitors in Tunisia, finding that fruticose lichens E. prunastri and R. farinacea had the lowest background levels of toxic elements, making them ideal for transplant-based pollution surveys.

The Use of Mosses in Biomonitoring of Air Pollution in the Terrestrial Environment: A Review

This paper is not about microplastics; it reviews the use of mosses as biomonitors for air pollution by metals and organic compounds.

Passive biomonitoring of airborne microplastics using lichens: A comparison between urban, natural and protected environments

Scientists used lichens (small plant-like organisms that grow on trees and rocks) to measure tiny plastic particles floating in the air around Rome, Italy. They found that urban areas had twice as many airborne microplastics as natural areas, with the plastic particles getting trapped by the lichens. This research matters because it shows lichens can help us track air pollution from microplastics, which scientists are studying for potential health effects when people breathe them in.

Moss, Lichens and Phytobenthos Bioindicators of Pollution

This review discusses the use of mosses, lichens, and aquatic algae as biomonitors of heavy metal pollution in air and water, covering both monitoring techniques and recent case studies. It is focused on heavy metal monitoring rather than microplastics specifically, but biomonitoring methods discussed are relevant to broader environmental pollution assessment.

Passive biomonitoring of airborne microplastics using lichens: A comparison between urban, natural and protected environments

Scientists used lichens (small plant-like organisms that grow on trees and rocks) to measure tiny plastic particles floating in the air around Rome, Italy. They found that urban areas had twice as many airborne microplastics as natural areas, with the longest plastic fibers found in the city center where people live and work. This matters because these same plastic particles that lichens trap from the air are also being breathed in by humans, potentially affecting our health.

Potential Role of Mosses in Evaluating Airborne Microplastic Deposition in Terrestrial Ecosystems

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.

Topography of UV-melanized Thalli of Lobaria pulmonaria (L.) Hoffm.

Researchers studied the topography of UV-melanized lichen tissue to understand how these organisms protect themselves from ultraviolet radiation. Lichens are known to colonize plastic surfaces in the environment, and studying their biology helps explain how microplastics persist in outdoor environments.

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.

Biomonitoring of Yozgat Çamlık National Park’s (Türkiye) Anthropogenic Microfiber Pollution: A Comprehensive Analysis of Lichen-Supported Air Quality Assessment and Microplastic Composition Insights

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.

An Assessment of distribution of Airborne Microplastic using Epiphytic Crustose Lichens in Surrounding Areas of an Open Dumpsite of a Plastic Crusher Plant at Kanadola, Sri Lanka

By collecting lichen samples at increasing distances from a plastic crushing plant in Sri Lanka, researchers detected significantly more airborne microplastics near the facility than at a control forest site, with no significant difference between the 50-meter and 50–100-meter zones. The findings demonstrate that industrial plastic processing sites are point sources of airborne microplastic emissions, and that lichens can serve as low-cost passive biomonitors for tracking atmospheric plastic pollution around such facilities.
