ClearEffects 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.
Assessment of the Effects of Environmental Concentrations of Microplastics on the Aquatic Snail Potamopyrgus antipodarum
Researchers examined the effects of environmentally relevant microplastic concentrations on the freshwater snail Potamopyrgus antipodarum, assessing impacts on this benthic invertebrate in an understudied freshwater ecosystem context.
Combined toxic effects of environmental predominant microplastics and ZnO nanoparticles in freshwater snail Pomaceae paludosa
Researchers assessed the toxic effects of zinc oxide nanoparticles and polypropylene microplastics, both individually and combined, on the freshwater snail Pomeacea paludosa over 28 days. The study found that combined exposure caused more severe oxidative stress, disrupted antioxidant and digestive enzyme activity, and led to tissue damage and DNA damage compared to individual pollutant exposure. Evidence indicates that microplastics interacting with nanoparticles can amplify toxic effects in freshwater organisms.
Assessment of oxidative stress, neurotoxicity, genotoxicity and prey-predator interactions in freshwater snails exposed to microplastics
This conference abstract investigates oxidative stress, nerve damage, DNA damage, and changes in predator-prey behavior in freshwater snails exposed to microplastics, pointing to a broad range of harmful biological effects. Understanding these impacts in aquatic invertebrates matters because they occupy important ecological roles and their exposure to microplastics can have cascading effects through food webs.
Understanding the harmful effects of polyethylene microplastics on Eisenia fetida: A toxicological evaluation
Earthworms (Eisenia fetida) exposed to increasing concentrations of polyethylene microplastics in soil showed lower body weight, reduced reproductive output, and disrupted antioxidant defenses — with oxidative stress markers climbing nearly 1.3-fold at the highest dose. These findings confirm that microplastic pollution degrades soil ecosystem health at concentrations that could plausibly occur in contaminated agricultural land.
Assessing the presence of microplastic in agriculture soils irrigated with treated waste waters using Lumbricus sp.: Ecotoxicological effects
Researchers collected earthworms from agricultural soils irrigated with treated wastewater in Morocco and found microplastics had accumulated in both the soil and the worms' tissues. The microplastic exposure caused oxidative stress and cellular damage in the earthworms. This study demonstrates that using treated wastewater for farming, a common practice in water-scarce regions, introduces microplastics into agricultural soil where they can harm soil organisms and potentially enter the food chain.
Polyethylene Microplastics Affected Survival Rate, Food Intake and Altered Oxidative Stress Parameters in Freshwater Snail Indoplanorbis exustus
Researchers exposed freshwater snails to various concentrations of low-density polyethylene microplastics and measured the effects on survival and physiology. The study found significant increases in oxidative stress markers and lipid peroxidation, along with reduced food intake and body weight, at higher concentrations. Evidence indicates that microplastics cause broad physiological impairment in freshwater invertebrates, and affected snails failed to recover even after exposure ended.
Dietary consumption of polypropylene microplastics alter the biochemical parameters and histological response in freshwater benthic mollusc Pomacea paludosa
Researchers exposed freshwater snails (Pomacea paludosa) to polypropylene microplastics through their diet at three concentrations over 28 days and measured biochemical and tissue-level responses. They found significant changes in antioxidant enzyme activity and histological damage in the digestive gland, with effects worsening at higher concentrations. The study suggests that dietary microplastic exposure can cause oxidative stress and organ damage in freshwater benthic organisms.
Ecotoxicological impacts of polyethylene, polystyrene and polyamide on the land snail Cantareus aspersus in a life cycle experiment
Researchers exposed garden snails (Cantareus aspersus) to polyethylene, polystyrene, or polyamide microplastics at 0.1%, 1%, and 10% concentrations in food across a full life cycle experiment. All three polymer types reduced growth, reproduction, and survival at the highest dose, with polyamide causing the most consistent toxicity, suggesting terrestrial gastropods are at risk from environmental microplastic exposure.
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.
Tracing microplastic (MP)-derived dissolved organic matter in the infiltration of MP-contaminated sand system and its disinfection byproducts formation
Researchers investigated the combined effects of polystyrene microplastics and cadmium on the freshwater snail Bellamya aeruginosa, finding that co-exposure produced greater oxidative stress and tissue damage than either contaminant alone. The microplastics enhanced cadmium bioavailability in tissues.
Response of soil biochemical properties and ecosystem function to microplastics pollution
This study found that polyethylene microplastics significantly disrupted soil health by reducing enzyme activity, lowering nutrient availability, and impairing overall ecosystem function. Smaller microplastics caused more damage than larger ones, and the effects were dose-dependent, suggesting that as microplastic pollution accumulates in agricultural soil, it could increasingly threaten the soil health that food production depends on.
Impacts of microplastics and heavy metals on the earthworm Eisenia foetida and on soil organic carbon, nitrogen and phosphorus
Researchers assessed the combined effects of polypropylene microplastics and a heavy metal mixture (copper, chromium, and zinc) on the earthworm Eisenia foetida and on soil organic carbon, nitrogen, and phosphorus cycling. The study found that co-contamination exacerbated adverse effects on earthworm survival and soil nutrient dynamics compared to single-pollutant exposures, highlighting synergistic risks of combined microplastic and metal pollution in terrestrial ecosystems.
Impacts of PVC microplastic ingestion on Biomphalaria alexandrina: behavioral, physiological, and histological responses
Researchers exposed the freshwater snail Biomphalaria alexandrina to PVC microplastics and measured behavioral, physiological, and histological outcomes. They found concentration-dependent harm including reduced feeding and survival, oxidative stress, and damage to digestive glands.
Uptake and adverse effects of polyethylene terephthalate microplastics fibers on terrestrial snails (Achatina fulica) after soil exposure
Researchers exposed terrestrial snails to polyethylene terephthalate microplastic fibers in soil and found that the snails ingested and excreted the fibers, but exposure caused visible damage to the particles and oxidative stress in the animals. Higher concentrations led to measurable changes in growth and feeding behavior. The study provides evidence that microplastic fibers in soil can harm land-dwelling organisms that play important roles in soil ecosystems.
Assessment of fate and impacts of microplastics in terrestrial environment using the snail Cantareus aspersus
Researchers used the land snail Cantareus aspersus as a bioindicator to assess the fate and effects of microplastics in terrestrial soils, conducting exposure studies that demonstrated microplastic uptake, tissue accumulation, and toxic effects in this organism. The work provides one of the few detailed assessments of microplastic risk in soil ecosystems using a terrestrial invertebrate model, contributing data to fill a significant gap in terrestrial ecotoxicology.
Impacts of microplastics and heavy metals on the earthworm Eisenia fetida and on soil organic carbon, nitrogen, and phosphorus
Researchers found that co-contamination by polypropylene microplastics and heavy metals (Cu, Cr, Zn) had synergistic adverse effects on earthworms and soil quality, reducing organic carbon and nitrogen levels more than either contaminant alone.
Combined toxicity of polyethylene microplastics and nickel oxide nanoparticle on earthworm (Eisenia andrei): oxidative stress responses, bioavailability and joint effect
Researchers studied the combined toxicity of polyethylene microplastics and nickel oxide nanoparticles on earthworms over 28 days. They found that smaller microplastics caused greater oxidative stress, and the combination of both pollutants was more harmful than either one alone. The study suggests that the co-occurrence of microplastics and metal nanoparticles in soil can amplify negative effects on soil-dwelling organisms.
Three-dimensional synergistic mechanism ofphysical injury, microbiota dysbiosis, and gene transfer in the gut of Cipangopaludina cathayensisunder microplastics and roxithromycin exposure
Researchers exposed freshwater snails to polystyrene microplastics, the antibiotic roxithromycin, and their combination to study effects on gut health. They found that co-exposure caused severe intestinal damage, disrupted gut microbiota, and dramatically increased antibiotic resistance gene levels by over 1000 percent. The study reveals a three-way mechanism of physical injury, microbial disruption, and gene transfer that amplifies ecological risks from combined pollutants.
Assessment of microplastic pollution on soil health and crop responses: Insights from dose-dependent pot experiments
Researchers combined field investigation and pot experiments to assess how microplastic contamination at different doses affects soil health indicators and crop growth performance. Field soils showed measurable microplastic contamination, and pot experiments demonstrated dose-dependent effects on soil enzyme activity, water retention, and plant growth metrics.
Combined contamination of microplastic and antibiotic alters the composition of microbial community and metabolism in wheat and maize rhizosphere soil
A study found that when soil is contaminated with both microplastics and antibiotics together, the damage to wheat and maize seedlings is worse than from either contaminant alone, with increased root oxidative stress and disrupted soil bacterial communities. This combined contamination, common in agricultural soils treated with plastic mulch and livestock manure, could affect crop health and food quality.
Ecotoxicological risk of co-exposure to fosthiazate and microplastics on earthworms (Eisenia fetida): Integrating biochemical and transcriptomic analyses
Researchers investigated the combined toxic effects of the insecticide fosthiazate and microplastics on earthworms using both biochemical and genetic analyses. They found that co-exposure increased oxidative stress, DNA damage, and disrupted metabolic pathways more severely than either pollutant alone. The study suggests that microplastics may amplify pesticide toxicity in soil organisms, raising concerns about their combined impact on soil ecosystem health.
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.
