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.
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.

Polyethylene microplastics were shown to act as vectors for organic pollutants including pharmaceuticals and pesticides in soil, with earthworm bioaccumulation assays and molecular endpoints revealing that MPs increased contaminant uptake compared to soil exposure alone.
Soil health risks caused by interactions of microplastics and pesticides
Chlorpyrifos adsorption and desorption on pristine and UV-aged LDPE and biodegradable microplastics derived from plastic mulch films was investigated in laboratory experiments, along with bioconcentration in earthworms. Aging altered the adsorption-desorption behavior of both plastic types and affected pesticide bioavailability to earthworms, highlighting risks from pesticide-microplastic interactions in agricultural soils.
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 behaviors of atrazine and imidacloprid on high temperature aged microplastics: Mechanism and influencing factors
Researchers investigated how aged polyethylene microplastics — the kind that have been weathered by UV light and heat in the environment — adsorb common agricultural pesticides, finding that microplastics can accumulate pesticides like atrazine and imidacloprid at high concentrations through hydrophobic (water-avoiding) interactions. This "Trojan horse" effect means microplastics can carry and potentially concentrate pesticides as they move through water environments.
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 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.
