The results inform assessments of whether microplastics in intensively farmed soils amplify herbicide mobility and bioavailability.
Insight into the effect of microplastics on the adsorption and degradation behavior of thiamethoxam in agricultural soils

Interactions 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.
How does soil contamination by microplastics interferes the sorption and desorption processes of three herbicides?
Researchers tested how varying proportions of polyethylene microplastics (0-100% by weight) affected the sorption and desorption of three herbicides (hexazinone, diuron, S-metolachlor) in soil. Microplastic presence significantly altered sorption behavior for S-metolachlor, with effects depending on microplastic concentration and herbicide chemical structure.
Adsorption-desorption of propyrisulfuron in six typical agricultural soils of China: Kinetics, thermodynamics, influence of 38 environmental factors and its mechanisms
This study investigated how the common herbicide propyrisulfuron behaves in six different Chinese agricultural soils, and notably found that microplastic contamination in the soil was one of 38 environmental factors influencing how much of the herbicide was adsorbed. The herbicide bound tightly enough to soil particles that residues could persist and potentially leach into groundwater with continued use. The incidental finding about microplastic influence on herbicide adsorption points to a broader issue: microplastics in farmland soils may alter the behavior of pesticides and other agrochemicals, with implications for both crop safety and water quality.
Effects of microplastics on the environmental behaviors of the herbicide atrazine in soil: Dissipation, adsorption, and bioconcentration
Researchers examined how the presence of microplastics in soil affects the behavior of the herbicide atrazine, including how quickly it breaks down and how much is absorbed by plants. They found that microplastics reduced the herbicide's half-life in soil, increased its adsorption to soil particles, and significantly boosted its uptake into plant tissues. The study suggests that microplastic contamination in agricultural soils could change how pesticides behave, potentially increasing crop contamination.
Microplastics mulch film affects the environmental behavior of adsorption and degradation of pesticide residues in soil
Researchers tested how new, aged, and biodegradable polyethylene mulch film microplastics affect the adsorption and degradation of the pesticides imidacloprid and flumioxazin in soil. All three MP types slowed initial pesticide adsorption and extended the time to reach equilibrium, with aged MPs showing the greatest effect, potentially prolonging pesticide persistence in agricultural soils.
Atrazine sorption on biodegradable microplastics: Significance of microbial aging
Researchers found that soil microbial aging of biodegradable microplastics — polylactic acid (PLA) and PBAT — significantly alters their surface properties and increases their capacity to adsorb the herbicide atrazine, suggesting that biodegradable plastics may pose underappreciated pollutant-transport risks as they break down.
Adsorption of azoxystrobin and pyraclostrobin onto degradable and non-degradable microplastics: Performance and mechanism
Researchers studied how two common fungicide pesticides attach to both biodegradable and conventional microplastics in soil environments. They found that non-degradable microplastics absorbed more pesticide and released it more slowly than biodegradable alternatives. The study suggests that microplastics in agricultural soil may act as reservoirs for pesticides, potentially prolonging their environmental presence and ecological impact.
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.
Effects of neonicotinoid insecticides on transport of non-degradable agricultural film microplastics
Researchers investigated how neonicotinoid insecticides adsorb onto agricultural film microplastics and affect their transport through porous media, finding that neonicotinoids altered microplastic mobility in ways that could influence contaminant spread in farmland soils.
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.

Researchers studied how aging affects the ability of ABS microplastics to absorb herbicide-containing compounds from the environment. They found that weathered microplastics had a fivefold increase in surface area and absorbed significantly more chemical contaminants than new plastics. The findings highlight that as microplastics break down over time, they become more effective at accumulating harmful substances in the environment.

Does Microplastic Contamination in Agricultural Soils Decrease the Efficiency of Herbicides for Weed Control?
Researchers investigated how microplastic contamination in agricultural soils affects herbicide performance. They found that microplastics absorb herbicides onto their surfaces, reducing the chemicals' availability for weed control and slowing their degradation by inhibiting soil microbial activity. The study suggests that microplastic pollution in farmland may undermine herbicide efficacy while increasing the persistence of these chemicals in the environment.
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.
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.
