ClearPolyethylene microplastic toxicity to the terrestrial snail Cantareus aspersus: size matters
Researchers found that polyethylene microplastic size significantly affects toxicity in the terrestrial snail Cantareus aspersus, with smaller particles causing greater oxidative stress and cellular damage than larger ones.
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.
The effects of polystyrene microparticles on the environmental availability and bioavailability of As, Cd and Hg in soil for the land snail Cantareus aspersus
Researchers exposed land snails to soil contaminated with both polystyrene microplastics and toxic metals including arsenic, cadmium, and mercury. They found that while microplastics had limited effects on overall metal availability in soil, they did alter the speed and pattern of metal uptake into snail tissues. The study suggests that microplastics may subtly change how organisms absorb environmental contaminants, even when they do not dramatically change the total amount available.
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.
Bioaccumulation and ecotoxicological impact of micro(nano)plastics in aquatic and land snails: Historical review, current research and emerging trends
This review summarizes the ecotoxicological impacts of micro- and nanoplastics on aquatic and land snail species worldwide. Researchers found evidence of microplastic bioaccumulation in 40 gastropod species, with Asia showing the highest contamination levels, and documented harmful effects including behavioral changes, oxidative stress, and tissue damage. The study highlights that toxicity depends on particle composition, shape, and size, and identifies significant research gaps in understanding how these pollutants affect invertebrate communities.
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 exposure to polyethylene terephthalate microplastics (PET-MPs) induces faster growth but not oxidative stress in the giant snail Achatina reticulata
Earthworms were fed polyethylene terephthalate microplastics (PET-MPs) to assess dietary toxicity in a terrestrial model organism. PET-MP exposure induced physiological and biochemical changes in the earthworms, suggesting that PET contamination in agricultural soils poses risks to soil-dwelling invertebrates.
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.
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.
Petroleum-based and biodegradable microplastics alter tissue structure and fecundity in the eastern mudsnail (Ilyanassa obsoleta)
Researchers found that both petroleum-based and biodegradable (PLA) microplastics caused tissue damage to the digestive gland and reduced fecundity in eastern mudsnails at high exposures, with environmentally relevant concentrations of petroleum-based microplastics already inducing subtle but significant histological changes.
Hazardous or not – Are adult and juvenile individuals of Potamopyrgus antipodarum affected by non-buoyant microplastic particles?
Researchers exposed adult and juvenile mud snails (Potamopyrgus antipodarum) to a mixture of five common polymer types at low and high dietary doses, finding no effects on morphology, reproduction, or development to maturity — suggesting that particle size and chemical composition may matter more than polymer presence alone in determining microplastic harm to freshwater invertebrates.
Microplastic load and polymer type composition in European rocky intertidal snails: Consistency across locations, wave exposure and years
Researchers examined microplastic loads in rocky intertidal snails across four European locations, finding consistent polymer type compositions and ingestion patterns regardless of geographic location, wave exposure, or sampling year.
Impacts of some recyclable plastic on marine key species
Testing three types of microplastics (polyethylene, polypropylene, and polystyrene) from common packaging against marine crustaceans and algae, researchers found that polypropylene was acutely toxic to all crustacean species tested, while polystyrene was toxic to one amphipod species, but leachates from all plastics were non-toxic. The results highlight that microplastic toxicity varies significantly by polymer type and organism, meaning blanket risk assessments may miss species-specific harms.
Metabolic equilibrium and reproductive resilience: Freshwater gastropods under nanoplastics exposure
Researchers exposed freshwater snails to nanoplastics of two different sizes and found concentration-dependent effects on body condition and bioaccumulation, with larger particles accumulating more in tissues. While carbohydrate and protein reserves remained largely stable, lipid metabolism and mitochondrial function were affected at certain exposures. Despite these metabolic shifts, the snails maintained overall energy balance, suggesting some resilience to nanoplastic stress over the 21-day study period.
Ecotoxicological Effects of Polyvinyl Chloride (PVC) Microplastics on the Growth, Reproduction and Survival of Daphnia magna
Researchers exposed Daphnia magna to polyvinyl chloride microplastics at different concentrations, alone and combined with two algal food sources, and measured growth, reproduction, and survival. PVC microplastics reduced fecundity and survival in a dose-dependent manner, with food source type modulating the severity of toxicity effects.
Ingestion and toxicity of microplastics in the freshwater gastropod Lymnaea stagnalis: No microplastic-induced effects alone or in combination with copper
Scientists exposed the freshwater snail Lymnaea stagnalis to polystyrene microplastics alone and combined with copper, finding that the snails ingested and excreted microplastics but that neither microplastics alone nor in combination with copper caused measurable toxic effects.
Impact of Microplastic Fiber Pollution on Ramshorn Snail (Panorbella campanulata) Reproduction and Mortality
Lab experiments exposed freshwater ramshorn snails to polyester microfibers and found significant increases in mortality and reduced reproduction compared to controls. The snails were particularly sensitive to microplastic fiber exposure, suggesting that freshwater mollusks are vulnerable to even low levels of microplastic contamination in aquatic environments.
Unveiling the effects of polyethylene microplastic on the physiological responses across different size classes of Telescopium telescopium
Researchers exposed mangrove horn snails of two different size classes to environmentally relevant concentrations of polyethylene microplastics for 21 days and measured their energy balance and stress responses. They found that both small and large snails experienced negative energy balance and increased oxidative stress at medium and high microplastic concentrations. The study suggests that microplastic pollution in estuarine environments may threaten the survival of organisms across different life stages.
Polylactic acid versus polypropylene microplastics: ecotoxicological effects on Gammarus aequicauda using a multi-level approach
Researchers compared the ecotoxicological effects of bioplastic (polylactic acid) and fossil-based (polypropylene) microplastics on the amphipod Gammarus aequicauda over 60 days. Both types caused significant growth reduction by day 45, but polypropylene exposure led to lower survival rates and more pronounced reproductive impairment, while gene expression analysis showed both types induced similar stress responses over time.
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.
Assessment of the effects of environmental concentrations of microplastics on the aquatic snail Potamopyrgus antipodarum
This 31-day study tested the effects of polystyrene microplastics on the New Zealand mudsnail Potamopyrgus antipodarum, finding that even environmentally relevant concentrations reduced fertility in females. The results suggest microplastic pollution in freshwater environments can impair the reproductive success of small invertebrates at realistic exposure levels.
