ClearEffects 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.

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 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.
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.
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.

Researchers systematically explored how the pesticide atrazine adsorbs onto both pristine and aged microplastics in aquatic environments. The study found that aged microplastics had higher adsorption capacities than pristine ones, with the aging process and pH significantly affecting surface charge and adsorption behavior, suggesting that weathered microplastics may carry greater loads of chemical contaminants.
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-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.

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.
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.

Researchers investigated the adsorption and desorption behavior of the novel insecticide fluchlordiniliprole across four soil types and how factors including pH, temperature, biochar amendments, and microplastic presence affected these dynamics. Microplastics altered fluchlordiniliprole adsorption capacity in soils, demonstrating that plastic particles modify the fate and mobility of co-occurring pesticides in agricultural environments.
Influence of polyethylene-microplastic on environmental behaviors of metals in soil
Researchers investigated how polyethylene microplastics affect the adsorption, desorption, and bioavailability of heavy metals in soil. They found that adding microplastics altered how metals bind to soil particles and increased the mobility of certain metals like cadmium and lead. The study suggests that microplastic contamination in soils may change the environmental behavior of heavy metals, potentially increasing their availability to plants and soil organisms.

Investigation of the sorption behavior of atrazine in new and aged microplastic and evaluation of its phytotoxic potential
Researchers studied the sorption of atrazine onto new and aged polyethylene microplastics in distilled and nutrient-enriched (eutrophic) water, then assessed the phytotoxic effects on Lactuca sativa germination. Aged MPs adsorbed more atrazine than new MPs, and the combination increased phytotoxicity over atrazine alone, showing that weathered microplastics amplify herbicide risks in aquatic environments.
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.

The findings suggest that weathered microplastics in agricultural environments may amplify the harmful effects of pesticide contamination.
Aging of biodegradable-mulch-derived microplastics reduces their sorption capacity of atrazine
UV aging of biodegradable PBAT and PBST microplastics reduced their sorption capacity for the herbicide atrazine, with partition coefficients declining for both aged polymers due to changes in surface area, hydrophobicity, polarity, and crystallinity.
