Nanoplastic ingestion induces behavioral disorders in terrestrial snails: trophic transfer effectsviavascular plants
AI summary Read the abstract
This study tracked the transfer of nanoplastics through a terrestrial food chain, from soil to plants to snails, finding that snails exposed via plants showed behavioral disruptions compared to controls. The results demonstrate that nanoplastics can move up land-based food webs and cause measurable neurological effects in invertebrates.
This study investigated the transfer of plastic debris in a terrestrial environment from the soil to a plant (the mung bean,Vigna radiata), and then to a consumer (the African giant snail,Achatina fulica).

Quantitative tracking of nanoplastics along the food chain from lettuce (Lactuca sativa) to snails (Cantareus aspersus)
AI summary Read the abstract
Researchers tracked the transfer of nanoplastics through a terrestrial food chain from lettuce to snails using specially labeled particles. They confirmed that nanoplastics taken up by lettuce were transferred to snails that fed on the contaminated plants, with measurable accumulation in snail tissues. The study provides direct evidence that nanoplastics can move up the food chain through trophic transfer in land-based ecosystems.
Mass-based trophic transfer of polystyrene nanoplastics in the lettuce-snail food chain

Researchers traced the trophic transfer of polystyrene nanoplastics from water into lettuce plants and then into garden snails, finding measurable mass-based transfer at each step of the food chain even at low nanoplastic concentrations using pyrolysis-GC/MS quantification.
Ecotoxicological effects of micro- and nanoplastics on terrestrial food web from plants to human beings
AI summary Read the abstract
This review examined the ecotoxicological effects of micro- and nanoplastics across the terrestrial food web, from plants to humans. Researchers found that plants can take up these particles through roots and leaves, soil organisms are affected by altered soil properties, and the potential for transfer through the food chain raises concerns about human dietary exposure to micro- and nanoplastics.
Ecological effects of micro/nanoplastics on plant-associated food webs
AI summary Read the abstract
This review discussed the ecological effects of micro/nanoplastics (MNPs) on plant-associated above- and belowground food webs, tracing MNP uptake, ingestion, and bioaccumulation through multiple trophic levels. Key pathways were identified by which MNPs disrupt soil and plant-associated food webs, with implications for terrestrial biodiversity and agriculture.
Bioaccumulation, trophic transfer and exuvial elimination of polystyrene nanoplastics in a terrestrial predator-prey system
AI summary Read the abstract
Scientists fed nanoplastics to snails, then to beetle larvae, and found the plastic particles built up in the larvae's gut and slowed their growth, though it didn't spread up the food chain in larger amounts. This shows plastics can quietly stress animals as they move through nature's food web, a reminder that the same tiny particles turning up in our food and water may carry similar hidden risks.
