ClearEvaluation of the sorption/desorption processes of pesticides in biodegradable mulch films used in agriculture
Researchers evaluated how biodegradable mulch films used in agriculture interact with pesticide residues compared to conventional polyethylene films. The study found that biodegradable films actually retained higher amounts of pesticide residues and released less back into the soil than polyethylene, suggesting that these supposedly greener alternatives may act as more persistent reservoirs for agricultural chemical contaminants.
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.
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.
Methodology development: evaluation of structural, thermal, and mechanical properties of poly(lactic acid)/poly(butylene adipate-co-terephthalate) blends for biodegradable mulch
Researchers developed a methodology for formulating and characterizing biodegradable PLA/PBAT mulch films as alternatives to conventional polyethylene mulch that contributes to microplastic pollution in agriculture. The proposed approach covers scalable formulation, processing, and comprehensive characterization aligned with regulatory guidelines and industry standards for biodegradable mulch performance.
A laboratory comparison of the interactions between three plastic mulch types and 38 active substances found in pesticides
This laboratory study tested the sorption interactions between 38 pesticide active substances and three types of plastic mulch film, finding that on average plastics reduced the rate of pesticide degradation in soil by about 30%. Plastic mulch films used widely in agriculture can alter the persistence and behavior of pesticides in soil, compounding their combined environmental impact.
Sorption to mulch film decreases bioavailability of two model pesticides for earthworms in soil
This study investigated how agricultural mulch film microplastics affect the bioavailability of pesticides to earthworms in soil. Sorption of two model pesticides onto mulch film microplastics significantly decreased their bioavailability, suggesting MPs may alter the ecological risk profile of pesticide-contaminated agricultural soils.
Exploring sorption of pesticides and PAHs in microplastics derived from plastic mulch films used in modern agriculture
Researchers investigated how microplastics derived from agricultural mulch films sorb pesticides and polycyclic aromatic hydrocarbons, finding significant uptake that could facilitate transfer of these contaminants through farming environments.
Field test on the biodegradation of poly(butylene adipate-co-terephthalate) based mulch films in soil
Researchers buried four types of supposedly biodegradable plastic mulch films — used in farming to suppress weeds — in agricultural soil for over two years and found that all four still left behind microplastic fragments. This shows that even biodegradable plastics can accumulate in soil if used repeatedly each growing season.
Adsorption behavior and mechanism of five pesticides on microplastics from agricultural polyethylene films
Researchers studied how five common pesticides adsorb onto polyethylene microplastics derived from agricultural soil films. They found that all five pesticides bind to microplastic surfaces, with the process driven by both physical and chemical interactions. The study suggests that microplastics in agricultural soils could act as carriers for pesticide contamination, with adsorption capacity varying depending on the pesticide's chemical properties.
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.
A comparative study on the adsorption behavior and mechanism of pesticides on agricultural film microplastics and straw degradation products
Researchers compared how agricultural film microplastics and straw-derived cellulose particles adsorb pesticides in farmland soils, finding that both materials sorb pesticides but through different mechanisms, with microplastics showing higher affinity for hydrophobic compounds, potentially altering pesticide mobility and bioavailability.
Impact of plastic mulch film debris on soil physicochemical and hydrological properties
This study compared low-density polyethylene and biodegradable plastic mulch films in agricultural soils, finding that both types left plastic residues that altered soil water infiltration, aggregate stability, and other physicochemical properties relevant to crop productivity.
Thickness-dependent release of microplastics and phthalic acid esters from polythene and biodegradable residual films in agricultural soils and its related productivity effects
Researchers conducted a two-year study comparing the release of microplastics and phthalic acid esters from polyethylene and biodegradable mulch films of different thicknesses in agricultural soil. The study found that biodegradable films degraded significantly more than polyethylene films, with thinner films breaking down faster, and that microplastic release from residual films can affect soil properties and crop productivity.
Functionalization of slow-release fertilizers and “passive predation microplastics” mechanism for polylactic acid composites
Researchers developed a biodegradable fertilizer film made from polylactic acid (PLA) and modified lignin that can slowly release nutrients while breaking down naturally in soil, offering an alternative to conventional plastic mulch. The study also explored how plants absorb tiny fragments of bio-based plastics, which is important for understanding whether even biodegradable alternatives still pose risks to food safety.
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.

This review examines how residues from both conventional polyethylene and biodegradable plastic mulch films accumulate in agricultural soils and affect plant growth and soil health. Both types of mulch film residues are found to have negative effects on the soil-plant system, raising questions about the environmental safety of biodegradable plastic alternatives.
Polyethylene film incorporation into the horticultural soil of small periurban production units in Argentina
Researchers surveyed Argentine horticultural soils and found plastic film residues covering 10% of the soil area, then demonstrated in laboratory experiments that polyethylene film strongly adsorbs pesticides (up to 2,284 µg per gram of plastic versus 32 µg per gram of soil), suggesting plastic mulch residues act as pesticide reservoirs that may alter contaminant fate in agricultural fields.
Conventional low-density polyethylene microplastic induce stronger adverse effects on maize–soil–bacteria system than polylactic acid microplastic
A comparison of conventional low-density polyethylene (LDPE) and biodegradable polylactic acid (PLA) microplastics from mulch film found that LDPE consistently inhibited maize growth while low concentrations of PLA actually promoted it. Both plastic types entered maize root tissues but followed different pathways, and LDPE caused greater harm to soil bacterial communities, suggesting that switching from conventional to biodegradable mulch is genuinely beneficial for agricultural soil health.
