Quantifying, and assessing the impact of, microplastics in terrestrial samples
AI summary Read the abstract
Researchers developed methodologies to quantify microplastics (1 to 1000 micrometers) in terrestrial woodland environments, addressing the significant knowledge gap about microplastic concentrations and ecological impacts in soil ecosystems compared to the more extensively studied aquatic compartments.
Microplastics, particles 1 ¡ 1000 µm, are an emerging pollutant. Microplastics in sediment and aquatic environments have dominated research, leaving the world with an inadequate understanding of microplastics in terrestrial environments such as woodlands. Terrestrial ecosystems are crucial for the continued well-being of many species and functions and so it is important that the concentration and effects of microplastics in terrestrial environments are given more attention. This research will fill a knowledge gap by developing effective, innovative methodologies to further our understanding of the scale and impact of microplastics in terrestrial environments and supporting the creation of policies to better regulate microplastics.

Quantifying, and assessing the impact of, microplastics in terrestrial samples
AI summary Read the abstract
Researchers aimed to develop effective methodologies for quantifying and assessing the ecological impact of microplastics (1-1000 µm) in terrestrial environments such as woodlands, which have been understudied compared to aquatic and sediment systems. The study sought to fill knowledge gaps about microplastic concentrations and effects in terrestrial ecosystems to inform policy development.
The Scale and Distribution of Microplastic Pollution in the Soils of a UK Urban Woodland
AI summary Read the abstract
Sampling across Epping Forest in London found microplastics in every soil sample, with forested areas showing up to 5-fold higher concentrations than adjacent open areas (mean 2,937 vs. 543 particles/kg), suggesting forest canopies act as preferential accumulation zones for atmospheric microplastic deposition. The study reveals that even ancient woodlands in urban areas are heavily contaminated, with fibrous PET particles accumulating at concentrations comparable to agricultural soils, raising concerns for soil ecosystems and groundwater.
Microplastic in Terrestrial Ecosystems and the Soil?
AI summary Read the abstract
This review examined the occurrence and behavior of microplastics in terrestrial ecosystems and soils, questioning how particles move through and accumulate in soils and calling for more research on land-based microplastic impacts.
Plastic particles in soil: state of the knowledge on sources, occurrence and distribution, analytical methods and ecological impacts
AI summary Read the abstract
This comprehensive review of plastic particles in soil covered sources, occurrence, analytical detection methods, and ecological impacts, identifying gaps in knowledge about terrestrial plastic fate and effects compared to the more extensively studied marine environment.
Microplastics in soils: assessment, analytics and risks
AI summary Read the abstract
This review examines microplastic prevalence, analytical methods, and risks in soils, finding that terrestrial microplastic contamination has received far less attention than marine accumulation despite comparable or greater abundance. Researchers evaluated current difficulties in soil microplastic sampling, isolation, and identification and called for standardised methodologies to assess ecological and human health risks.
