ClearImpacts of conventional and alternative plastics on soil ecosystems
This PhD research investigated how conventional and alternative (biodegradable, bio-based) plastics and their leachates affect soil health, plant performance, and soil organisms. While biodegradable plastics degraded faster, leachates from both conventional and alternative plastics caused similar levels of soil toxicity and plant stress in some conditions.
Effects of Microplastics in Soil Ecosystems: Above and Below Ground
Researchers tested how three types of microplastics, including biodegradable polylactic acid, conventional polyethylene, and synthetic clothing fibers, affect soil ecosystems containing earthworms and ryegrass. They found that different plastic types caused distinct effects: fibers and biodegradable plastics reduced seed germination, polyethylene reduced earthworm body mass, and all types altered the structure of soil aggregates. The study provides evidence that microplastic contamination can disrupt both above-ground plant growth and below-ground soil health.
Microplastics in terrestrial environments: Reviewing current understanding to determine the positive and negative aspects of soil
This review examines microplastics in terrestrial soils, covering sources, distribution, and effects on soil health and organisms. It finds both negative impacts — reduced soil function, harm to earthworms and plants — and some neutral effects, highlighting significant research gaps.
Microplastics on the growth of plants and seed germination in aquatic and terrestrial ecosystems
This review examined the effects of microplastics on plant growth and seed germination in aquatic and terrestrial ecosystems, finding that microplastic presence can affect plant development through multiple mechanisms depending on polymer type, concentration, and the composition of the growing medium.
Current research trends on plastic pollution and ecological impacts on the soil ecosystem: A review
This review examines the current state of research on plastic pollution in soil ecosystems, an area that has received far less attention than marine plastic contamination. Researchers found that agricultural practices, sewage sludge application, and plastic mulch use are major sources of soil microplastic pollution, with earthworms being the most commonly studied organisms for assessing ecological impacts. The study calls for more research into how microplastics affect soil biodiversity, nutrient cycling, and long-term soil health.
Effect of Microplastics on the Germination and Growth of Terrestrial Plants
This review summarized studies on the effects of microplastics on the germination and growth of terrestrial plants, finding generally negative effects at high concentrations including reduced germination rates and root length. Effects varied by plant species, polymer type, and particle size, and the review highlighted limited data from realistic field exposures.
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 microplastics on soil environment and land plant growth: a review
This review examines how microplastics affect soil quality and plant growth through both direct toxicity and indirect changes to soil properties. Researchers found that microplastics can accumulate in plant tissues after entering the soil and may transfer through the food chain. The study highlights that soil microplastic contamination is a growing ecological concern that remains understudied compared to marine environments.
Perspectives and challenges of micro/nanoplastics‐induced toxicity with special reference to phytotoxicity
This review examined the phytotoxic effects of micro- and nanoplastics on plant systems, noting that plastic concentrations in terrestrial environments are often higher than in aquatic ones. Researchers found that these particles can alter soil enzymatic systems, affect soil microorganisms and earthworms, and impact plant growth and physiology, though the study emphasized that research on terrestrial phytotoxicity is still limited compared to aquatic studies.
Effect of Innovative Bio-Based Plastics on Early Growth of Higher Plants
Researchers tested five bio-based plastics on early plant growth and found that monocotyledonous plants were largely unaffected, while PLA-based plastics inhibited root growth in dicotyledonous plants by up to 22% and PBS-based plastic stimulated shoot growth, suggesting bio-based plastic particles are not entirely benign in soil environments.
Ecotoxicological effects of soil microplastic types and concentrations on earthworms
Researchers tested the effects of conventional polyethylene and polypropylene microplastics alongside biodegradable PBAT microplastics on earthworms over 28 days. They found that PP microplastics caused significant mortality at the highest concentration, while PBAT, despite being marketed as biodegradable, induced the highest levels of DNA damage and cellular stress. The study suggests that biodegradable plastics are not necessarily less harmful to soil organisms than conventional plastics.
Current research trends on plastic pollution and ecological impacts on the soil ecosystem: A review
This review examined plastic pollution in soil ecosystems, covering sources including sewage sludge, plastic mulch, and stormwater runoff, and the effects on soil structure, microbial communities, and earthworms. Microplastics in soil are a growing concern because farmland soils represent a major global reservoir of environmental plastic contamination.
Recent advances on microplastics/nanoplastics interaction with plant species: A concise review
This review synthesizes research on how microplastics and nanoplastics interact with plants, finding that plastic particles in soil can interfere with root uptake, germination, and crop yields depending on the type and concentration of plastic present. The findings are particularly relevant to human health because food crops grown in microplastic-contaminated agricultural soils may absorb or accumulate plastic particles, creating a direct dietary exposure route.
Macro- and micro- plastics in soil-plant system: Effects of plastic mulch film residues on wheat (Triticum aestivum) growth
Researchers studied how plastic mulch film residues, both conventional polyethylene and biodegradable types, affect wheat growth when mixed into soil. They found that both macro- and micro-sized plastic residues negatively impacted plant growth above and below ground, with effects varying depending on the plastic type and the presence of earthworms. The study highlights that agricultural plastic residues left in soil can meaningfully affect crop development and soil ecosystem health.
Effect of bio-based microplastics on earthworms Eisenia andrei
Researchers tested the effects of three innovative bio-based plastics on earthworms in long-term soil experiments to determine whether these alternatives to conventional plastics are safer for terrestrial ecosystems. They found that bio-based microplastics still affected earthworm health and behavior, though the severity varied depending on the type of polymer. The study suggests that switching from petroleum-based to bio-based plastics does not automatically eliminate risks to soil organisms.
Effects of Conventional Non-Biodegradable Film-Derived Microplastics and New Biodegradable Film-Derived Microplastics on Soil Properties and Microorganisms after Entering Sub-Surface Soil
Researchers compared the effects of conventional non-biodegradable plastic film-derived microplastics and biodegradable film-derived microplastics on soil biological properties, finding that both types altered soil microbial diversity and enzyme activity. Biodegradable microplastics produced distinct effects from conventional plastics, suggesting their environmental impacts should not be assumed equivalent.
A review of microplastics in the soil environment
This review summarizes the current state of knowledge about microplastic contamination in soil environments, covering sources, distribution, and effects on soil organisms and ecosystems. The study highlights that while aquatic microplastic research is more advanced, soil contamination poses significant but understudied risks to terrestrial ecosystems and food production.
Evaluation of the impact of polylactide microparticles on soil biota
Researchers evaluated the environmental impact of polylactide (PLA) bioplastic microparticles on soil organisms using earthworms and plants as bioindicators. They found that while PLA microparticles did not affect earthworm survival, they reduced reproductive capacity by approximately 50% at concentrations of 2.5% and above. The study suggests that even biodegradable bioplastics can have measurable ecological effects on soil organisms, particularly on earthworm reproduction.
Recent advances on ecological effects of microplastics on soil environment
This review summarizes recent advances in understanding the ecological effects of microplastics on soil environments. Researchers found that soils serve as major sinks for microplastics, which can alter soil properties, affect plant growth, disrupt soil microbial communities, and interact with other pollutants. The study highlights that terrestrial microplastic pollution may be even more pervasive than aquatic contamination and warrants greater research attention.

Migration and toxicology of microplastics in soil: A review
This review examines how microplastics migrate through soil, summarizes their known toxic effects on soil organisms and plants, and identifies key gaps in current understanding. Soils are increasingly recognized as major microplastic repositories, and their contamination has implications for food safety and ecosystem health.
Effect of conventional and biodegradable microplastics on earthworms during vermicomposting process
Researchers compared the effects of conventional polyethylene and biodegradable microplastics on earthworms during composting and found that both types caused stress at higher concentrations. Earthworm weight, reproduction, and survival were negatively affected by both plastic types, though biodegradable microplastics caused somewhat less harm. The findings suggest that biodegradable plastics are not entirely safe for soil organisms and can still disrupt composting processes.
The impact of microplastic on nematodes: Soil type, plastic amount and aging as determinants for the fitness of Caenorhabditis elegans
Researchers tested how two types of microplastics, conventional polyethylene and biodegradable PLA/PBAT, affected tiny soil worms called nematodes across different soil types. Conventional plastic at high concentrations reduced worm reproduction and growth, while the biodegradable plastic caused no harm. Importantly, as microplastics aged in the soil over time, their negative effects worsened, suggesting the long-term impact of plastic pollution in agricultural soil may be greater than short-term studies indicate.
