ClearWhat do we know about how the terrestrial multicellular soil fauna reacts to microplastic?
This review synthesized studies on how soil-dwelling animals — including earthworms, insects, and mites — respond to microplastic contamination, finding evidence of ingestion, tissue accumulation, and harmful effects across multiple soil organism groups. However, most studies used unrealistically high concentrations, making it difficult to draw firm conclusions about risks at current environmental levels.
What do we know about how the terrestrial multicellular soil fauna reacts to microplastic?
This review analyzed the available literature on how soil-dwelling animals respond to microplastics and found evidence of uptake, bioaccumulation, and harmful effects across many groups including earthworms, springtails, and beetles. Most studies used high concentrations not yet found in real soils, limiting conclusions about current environmental risks.
Implication of microplastics on soil faunal communities — identifying gaps of knowledge
This systematic review examines how microplastics in soil affect earthworms, springtails, mites, and other soil-dwelling creatures that are essential for healthy soil. The impacts are highly variable and depend on the type of plastic, particle size, and soil conditions, making broad conclusions difficult. The review identifies critical knowledge gaps, noting that most studies use unrealistically high microplastic concentrations, and calls for research at levels that match actual field conditions.
Assessing the impacts of microplastics on soil meso- and macro-fauna
This study aims to extend understanding of microplastic impacts beyond earthworms to include mites, collembolans, and other key soil invertebrate groups, developing ecotoxicology tests to establish risk assessment levels for microplastics in soil ecosystems.
Underestimated and ignored? The impacts of microplastic on soil invertebrates—Current scientific knowledge and research needs
This review highlights the critical gap in research on how microplastics affect soil invertebrates, noting that soil ecosystems receive far more plastic pollution than oceans yet the ecological consequences for soil fauna remain poorly understood and largely unstudied.
The forgotten impacts of plastic contamination on terrestrial micro- and mesofauna: A call for research
This review highlights the overlooked impact of microplastics on tiny soil organisms like mites, springtails, and nematodes that play critical roles in keeping soil ecosystems healthy. Ingesting microplastics can harm their development and reproduction, which disrupts nutrient cycling and soil food webs. Since these organisms help maintain the soil that grows our food, their decline from plastic pollution could have cascading effects on agriculture and human nutrition.
Effects of environmentally relevant mixtures of microplastics on soil organisms
Researchers exposed earthworms and springtails to environmentally realistic mixtures of microplastics commonly found in agricultural soils treated with sewage sludge. They found that earthworms ingested microplastics in proportion to exposure levels, and at higher concentrations, both species showed reduced reproduction. The study provides evidence that real-world microplastic mixtures in farm soils can affect important soil organisms at concentrations already found in the environment.
Effects of environmentally relevant mixtures of microplastics on terrestrial organisms
Researchers tested the effects of environmentally realistic microplastic mixtures on the earthworm Eisenia andrei and the springtail Folsomia candida as soil model organisms. Even at environmentally relevant concentrations, the microplastic mixture caused measurable negative effects on soil organism health and reproduction.
Plastic pollution in terrestrial ecosystems: Current knowledge on impacts of micro and nano fragments on invertebrates
This review summarizes research on how micro- and nanoplastics affect soil-dwelling invertebrates like earthworms and insects, finding that effects vary widely depending on plastic type, shape, concentration, and exposure time. While no broad conclusions could be drawn, the documented sublethal effects on soil organisms could disrupt the soil ecosystems that support the crops humans depend on for food.
Effects of pristine microplastics and nanoplastics on soil invertebrates: A systematic review and meta-analysis of available data
About 49% of 1,061 biological endpoints were significantly affected by pristine micro- and nanoplastics across 56 studies on soil invertebrates, with polymers containing chloro and phenyl groups causing the most harm; concentrations above 1 g/kg in soil decreased earthworm growth and survival.
Interaction of Invertebrates and Synthetic Polymers in Soil: A Review
This review summarizes how microplastics in soil harm invertebrates including nematodes, springtails, and earthworms, while some soil animals can fragment or ingest and transport plastic particles. The presence of microplastics in soil disrupts the gut function of soil organisms that play critical roles in maintaining healthy, productive soils.
Meta-analysis reveals differential impacts of microplastics on soil biota
Soil microplastic contamination ranged from 0.34 to over 410,000 items/kg across sites, and their presence significantly increased mortality rates and decreased individual numbers, diversity, and reproduction of soil organisms, though biomass was unaffected due to opposing effects on different organism groups.
Microplastics as Emerging Soil Pollutants
This review covers how microplastics enter and accumulate in soils, their effects on soil health, microbial communities, soil fauna, and plant growth, and the implications of widespread soil plastic contamination for ecosystem function.
Micro Plastic Pollution in Soil Environment: A Comprehensive Review
This comprehensive review covers sources, distribution, degradation pathways, and ecological effects of microplastics in soil environments, highlighting threats to soil fauna, microbiota, and plant growth.
Soil microplastic characteristics and the effects on soil properties and biota: A systematic review and meta-analysis
Meta-analysis of 2,886 experimental groups found that microplastics significantly decreased soil bulk density and aggregate stability, indicating structural damage, while also reducing plant root biomass and soil phosphatase activity. Invertebrates were more sensitive to microplastics than other soil organisms, as particles can pass through nematode gut walls causing oxidative stress and altered gene expression.
Interactions between microplastics and soil fauna: A critical review
This review summarizes how microplastics affect soil animals like earthworms and nematodes, which play crucial roles in maintaining healthy soil. Microplastics can harm these organisms through ingestion, tissue damage, oxidative stress, and disruption of their gut bacteria, reducing their ability to decompose organic matter and cycle nutrients. In turn, soil animals can break down and spread microplastics through the soil, potentially transferring them up the food chain to animals and humans.
Quantification and Ecotoxicological Evolution of Microplastics in Soil Ecosystem
