ClearInteractions of traditional and biodegradable microplastics with neonicotinoid pesticides
Researchers investigated how both traditional and biodegradable microplastics interact with neonicotinoid pesticides in agricultural environments. They found that all microplastic types could adsorb the pesticide thiacloprid, but biodegradable microplastics showed different sorption behavior and higher desorption rates compared to conventional plastics. The study suggests that biodegradable microplastics may actually increase pesticide mobility in soils, creating a previously unrecognized pathway for agricultural chemical contamination.

Adsorption behavior and mechanism of five pesticides on microplastics from agricultural polyethylene films
Researchers studied how five common pesticides adsorb onto polyethylene microplastics derived from agricultural soil films. They found that all five pesticides bind to microplastic surfaces, with the process driven by both physical and chemical interactions.

Adsorption behavior of three triazole fungicides on polystyrene microplastics
Researchers studied how three commonly used triazole fungicides adsorb onto polystyrene microplastics under various environmental conditions. They found that smaller microplastic particles adsorbed greater quantities of fungicides, and that environmental factors like pH and salinity significantly influenced adsorption capacity. The findings suggest that microplastics in agricultural environments could act as carriers for pesticide residues, potentially altering their environmental fate and bioavailability.
Adsorption behavior and mechanism of different types of (aged) microplastics for napropamide in soils
Researchers studied how different types of microplastics, both conventional and biodegradable, affect the soil absorption of the herbicide napropamide. They found that aged microplastics had significantly different adsorption properties than new ones, and that the presence of microplastics generally altered how the herbicide behaved in soil. The findings suggest that microplastic pollution may change how agricultural chemicals move through and persist in farmland.
Effect of PVC microplastics on pesticide sorption behavior in soil: Key roles of particle size and aging
Researchers studied how PVC microplastics of different sizes and aging states affect pesticide behavior in agricultural soil. They found that smaller and aged microplastics significantly enhanced pesticide adsorption and made it harder to release back into the soil, primarily through hydrogen bonding mechanisms. The study highlights the need to account for microplastic contamination when assessing how pesticides move through and persist in agricultural soils.
Comparative analysis on the sorption kinetics and isotherms of fipronil on nondegradable and biodegradable microplastics
The sorption behavior of the pesticide fipronil onto biodegradable and conventional non-degradable microplastics was compared through both experiments and molecular dynamics simulations, finding differences in how strongly each plastic type binds the pesticide. Biodegradable plastics, often considered safer alternatives, may carry different pesticide contamination risks than conventional plastics when they fragment into microparticles.
Adsorption–desorption and leaching behavior of benzovindiflupyr in different soil types
This study examined how the fungicide benzovindiflupyr behaves in different soil types, finding that microplastics in soil can change how the pesticide is absorbed and moves through the ground. The type and size of microplastics influenced whether the fungicide stayed in place or leached toward groundwater. This is relevant because when microplastics and agricultural chemicals coexist in farmland, they can interact in ways that may increase groundwater contamination and human exposure.

Dissipation of penthiopyrad in polyethylene microplastics coexisting soils: Roles of soil properties and microbial communities
Researchers studied how polyethylene microplastics affect the breakdown of the fungicide penthiopyrad in soil and found that the plastics modified dissipation rates through adsorption and desorption but did not significantly alter the fungicide's ultimate persistence. Specific bacterial and fungal genera, including Sphingomonas and Trichocladium, played key roles in degrading the fungicide. The study highlights that soil microorganisms could serve as natural remediation agents for co-contamination by microplastics and pesticides.
A comparative study on the adsorption behavior of pesticides by pristine and aged microplastics from agricultural polyethylene soil films
Researchers compared how pristine and aged agricultural polyethylene film microplastics adsorb pesticides. They found that aged films, which develop rougher surfaces, more cracks, and oxygen-containing chemical groups, adsorb pesticides more readily than pristine ones. The study suggests that weathered agricultural microplastics in soil may act as carriers for pesticide contamination, potentially increasing environmental and human health risks.

This review compares how both biodegradable and conventional microplastics absorb chemical contaminants like pesticides and heavy metals from the environment. Researchers found that microplastics can act as carriers for hazardous chemicals, and that biodegradable plastics are not necessarily safer in this regard, as they can also concentrate and transport pollutants.
Adsorption of neonicotinoid insecticides by mulch film-derived microplastics and their combined toxicity
Researchers studied how microplastics from agricultural mulch films interact with common insecticides used on crops. They found that biodegradable plastic (PBAT) microplastics adsorbed more pesticide than conventional polyethylene microplastics, and that aging increased this adsorption capacity. When combined, the microplastics and insecticides were more toxic to soil organisms than either pollutant alone, suggesting an underappreciated risk in agricultural soils.
