ClearDivergent impacts of conventional and biodegradable microplastics on pesticide fate and toxicity in a soil–chive system, underscoring a soil-plant-microbe disruption
Researchers found that biodegradable polylactic acid (PLA) microplastics, despite being marketed as eco-friendly, significantly delayed pesticide degradation in soil and increased plant uptake of a toxic pesticide metabolite by up to 59%. PLA disrupted beneficial soil bacteria and interfered with plant detoxification pathways, while conventional polyethylene microplastics had comparatively milder effects. The study suggests that biodegradable plastics may pose unexpected risks when they interact with pesticides 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.
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.
Effects of Microplastics on Bioavailability, Persistence and Toxicity of Plant Pesticides: An Agricultural Perspective
This review examines how microplastics in soil interact with pesticides, generally reducing pesticide effectiveness by absorbing the chemicals onto their surfaces. While this lowers the immediate toxicity of pesticides, it also makes them last longer in the environment and may reduce pest control in agriculture, potentially affecting food production and the long-term safety of the food supply.
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.
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.
Comparative analysis of the sorption behaviors and mechanisms of amide herbicides on biodegradable and nondegradable microplastics derived from agricultural plastic products
Sorption behavior of amide herbicides onto biodegradable and non-biodegradable microplastics was compared, finding that polymer type and weathering state significantly influenced herbicide uptake. 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
Researchers found that microplastics in agricultural soil alter both the adsorption and degradation behavior of the pesticide thiamethoxam, with different plastic types showing varying effects on how the pesticide binds to soil and breaks down over time.
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.
Influence on the processes of retention and transport of pesticides and ecotoxicity of microplastics in a tropical soil
Researchers investigated how high-density polyethylene microplastics from agricultural mulch films affect the behavior of three pesticides in tropical soil, finding that microplastics altered pesticide sorption, transport, and leaching while also increasing ecotoxicological effects on earthworms.
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.
Impact of different microplastics polymers and albendazole and pyraclostrobin mix on arugula (Eruca vesicaria) physiology and growth
Researchers exposed arugula plants to conventional (LDPE) and biodegradable (PBAT) microplastics combined with a pesticide-antiparasitic mixture, and found that only the conventional plastic significantly amplified the chemicals' toxicity, reducing plant growth more than either pollutant alone. This shows that conventional microplastics can act as carriers that worsen the effects of agricultural chemicals in soil.
Sorption to mulch film decreases bioavailability of two model pesticides for earthworms in soil
Researchers investigated how polyethylene mulch film microplastics interact with pesticides in agricultural soil and their combined effects on earthworms. The study found that sorption of pesticides to mulch film microplastics actually decreased the bioavailability of two model pesticides to earthworms, suggesting that in some cases microplastics may reduce rather than increase pesticide toxicity to soil organisms.
Effect of microplastic on sorption, toxicity, and mineralization of 2,4-dichlorophenoxyacetic acid ionic liquids
Researchers studied how polyethylene microplastics interact with herbicide formulations designed as ionic liquids in the environment. They found that the surface-active components of these herbicides readily adsorb onto microplastic surfaces, potentially altering how the chemicals move through ecosystems. The study raises concerns that microplastics may act as carriers for agricultural chemicals, prolonging their persistence in soil and water.
Chlorpyrifos degradation and its impacts on phosphorus bioavailability in microplastic-contaminated soil
This study found that microplastics made from polylactic acid (a biodegradable plastic) in soil changed how the pesticide chlorpyrifos breaks down and altered the availability of phosphorus, a key nutrient for crops. The microplastics slowed pesticide degradation and affected soil enzyme activity, which could impact both food safety and crop nutrition. The findings show that even biodegradable microplastics can disrupt important soil processes that affect the food supply.
Adsorption of acetamiprid, chlorantraniliprole and flubendiamide on different type of microplastics present in alluvial soil
Researchers investigated the adsorption of three pesticides (acetamiprid, chlorantraniliprole, and flubendiamide) onto different types of microplastics in alluvial agricultural soil, finding that microplastics act as vectors for these organic pesticide compounds and affect soil microorganism activity.
Interactions of Microplastics with Pesticides in Soils and Their Ecotoxicological Implications
This review examines how microplastics interact with pesticides in soil environments, finding that microplastics can sorb and transport pesticides, potentially altering their bioavailability and toxicity to soil organisms and ecosystems.
Agricultural film-derived microplastics elevate the potential risk of pesticides in soil ecosystem: The inhibited leaching by altering soil pore
Researchers found that microplastics derived from agricultural mulch film can increase the environmental risk of pesticides by altering soil pore structure and inhibiting pesticide leaching. Smaller microplastic particles had a stronger effect on trapping pesticides in the upper soil layers, leading to higher localized concentrations. The study suggests that the co-occurrence of microplastics and pesticides in farm soils may create compounding contamination risks for agricultural ecosystems.
Pesticide bioaccumulation in radish produced from soil contaminated with microplastics
Researchers examined how microplastics in soil affect the bioaccumulation of pesticides in radishes, finding that aged microplastics enhanced the uptake of chlorpyrifos into the edible root. The study suggests that the combination of microplastics and pesticide mixtures in agricultural soils may increase food safety risks beyond what would be expected from individual contaminants alone.
Influence of microplastic addition on glyphosate decay and soil microbial activities in Chinese loess soil
Adding polyethylene microplastics to soil influenced the degradation of the herbicide glyphosate and altered microbial activity, with effects depending on the concentration of both microplastics and glyphosate. The findings suggest that microplastic contamination in agricultural soils could affect how long pesticides persist and how soil microbes function.
