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.
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.

Effects of microplastic pollution on agricultural soil and crops based on a global meta‐analysis
This meta-analysis examined data from studies worldwide to assess how microplastic pollution affects agricultural soil and crops. Researchers found that microplastics can alter soil properties including enzyme activity and nutrient availability, with effects varying by plastic type, concentration, and size. The study suggests that microplastic contamination in farmland may affect both soil health and crop growth in ways that depend heavily on local conditions.
Microplastics Can Change Soil Properties and Affect Plant Performance
Researchers tested six different types of microplastics in soil and found that they altered key soil properties including water-holding capacity, bulk density, and microbial activity. These changes in soil structure had cascading effects on plant growth, with some microplastic types reducing above-ground biomass. The study demonstrates that microplastics can fundamentally change how soil functions, with consequences for plant health and ecosystem stability.
Microplastic Contamination in Agricultural Soils: Impacts on soil properties and plant performance

Aged polyethylene microplastics modulate herbicide and antibiotic bioavailability and plant responses: A case study with glyphosate and tetracycline
Scientists found that tiny plastic particles commonly found in farm soil can stick to plant roots and change how plants absorb harmful chemicals like pesticides and antibiotics. The plastic pieces made plants more stressed and damaged, reducing important nutrients like chlorophyll by 30%. This matters because it could affect the safety and quality of the food we eat, since these plastic particles are becoming more common in agricultural areas where our crops are grown.
The effects of microplastics on crop variation depend on polymer types and their interactions with soil nutrient availability and weed competition
Researchers investigated how different types of microplastics interact with soil nutrient availability and weed competition to affect crop growth. The study found that the effects of microplastics on plant performance depend on the polymer type and are modulated by fertilization levels and competition from weeds, suggesting that real-world agricultural impacts of microplastic pollution may be more complex than laboratory studies indicate.

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.
Agricultural films derived microplastics intensify acetochlor toxicity on soil health
Researchers examined whether microplastics from agricultural plastic films worsen the toxic effects of the herbicide acetochlor on soil health. They found that both conventional polyethylene and biodegradable PBAT microplastics combined with the herbicide caused soil acidification, depleted organic carbon, and disrupted microbial communities more severely than either contaminant alone. The study suggests that microplastics from farming materials may amplify the harmful effects of commonly used agricultural chemicals on soil ecosystems.
