ClearResponse of common bean (Phaseolus vulgaris L.) growth to soil contaminated with microplastics
A pot experiment adding LDPE and biodegradable (PLA/PBAT) microplastics to soil at 0.5–2.5% by weight found no significant effects on common bean shoot or root biomass, though higher LDPE concentrations increased specific root nodules, suggesting subtle effects on nitrogen-fixing symbiosis.
The effects of diverse microplastics on adzuki bean (Vigna angularis) growth and physiologic properties
Researchers tested the effects of three types of microplastics at different concentrations on adzuki bean growth and found that all types caused some damage, with biodegradable polylactic acid having the strongest negative impact on plant biomass. Higher microplastic concentrations significantly reduced chlorophyll content and triggered antioxidant stress responses. The study suggests that even supposedly eco-friendly biodegradable plastics can harm crop plants when they accumulate in soil.
Ecotoxicity and genotoxicity of polystyrene microplastics on higher plant Vicia faba
Researchers exposed fava bean root tips to polystyrene microplastics and nanoplastics and found reduced biomass, increased oxidative stress, and genetic damage in the plant cells.

This study compared how conventional polyethylene microplastics and biodegradable alternatives (PBAT and PLA) affect soil bacteria and nutrient cycling in soybean fields. The biodegradable microplastics actually caused more harm to soybean growth than conventional ones, reducing shoot biomass by up to 34% and disrupting nitrogen availability in soil. This challenges the assumption that biodegradable plastics are always better for the environment and raises questions about their impact on agricultural productivity and food security.
Response of peanut plant and soil N-fixing bacterial communities to conventional and biodegradable microplastics
Researchers tested how conventional plastics (polyethylene and polystyrene) and a biodegradable plastic (polylactic acid) affect peanut plant growth and nitrogen-fixing soil bacteria. They found that while none of the plastics reduced plant biomass, the biodegradable PLA at high doses dramatically altered soil nitrogen levels and bacterial community composition. The study suggests that biodegradable plastics may not be as harmless to agricultural soil ecosystems as commonly assumed.

Researchers tested different concentrations of polyethylene microplastics on blackgram plants and their surrounding soil. They found that higher microplastic levels significantly reduced plant growth, photosynthesis, and yield while also altering soil properties and microbial activity. The study demonstrates a dose-dependent relationship, with the most severe impacts occurring at the highest microplastic concentrations.
Unraveling the impact of nano-microscale polyethylene and polypropylene plastics on Nicotiana tabacum: Physiological responses and molecular mechanisms
Researchers exposed tobacco plants to polyethylene and polypropylene microplastics of different sizes and found that both types suppressed plant growth in a dose-dependent manner, with polypropylene being more toxic. The microplastics disrupted photosynthesis, triggered oxidative stress, and altered hormone signaling and defense pathways in the plants. These findings demonstrate that microplastic contamination in soil can impair crop growth at the molecular level, potentially affecting agricultural productivity.
Physiological and biochemical effects of polystyrene micro/nano plastics on Arabidopsis thaliana
Experiments on the model plant Arabidopsis showed that polystyrene nano- and microplastics reduced seed germination, stunted growth, lowered chlorophyll levels, and triggered oxidative stress in roots, with smaller particles and higher concentrations causing the most damage. These findings raise concerns about how microplastic contamination in agricultural soil could affect crop health and ultimately food production.
Microplastics Can Alter Plant Parameters Without Affecting the Soil Enzymatic Activity in White Lupine
Low-density polyethylene, polypropylene, and polyamide microplastics exposed to white lupine (Lupinus albus) over 110 days altered plant growth parameters—including root morphology and chlorophyll content—without significantly affecting soil enzymatic activity. The findings suggested MPs can impair legume health through mechanisms not captured by soil enzyme assays alone.
Cyto-Genotoxic Effect Causing Potential of Polystyrene Micro-Plastics in Terrestrial Plants.
Exposure of plant root cells to polystyrene microplastics at multiple size ranges caused chromosome aberrations, reduced root length, and other cytological damage at higher concentrations. The findings indicate that microplastic particles can cause genotoxic effects in terrestrial plants, with implications for the health of food crops grown in plastic-contaminated soils.

Researchers conducted pot experiments to assess how polystyrene microplastics in different shapes and concentrations affect wheat growth, photosynthesis, and oxidative stress. They found that powder-shaped microplastics caused the most severe reductions in plant height, biomass, and chlorophyll content, especially at higher concentrations. The study suggests that both the shape and concentration of microplastics in soil play important roles in determining their phytotoxic effects on crop plants.

Researchers compared biodegradable PBAT plastic microplastics with conventional polyethylene microplastics in soil and found that the biodegradable version actually caused more harm to plant growth and soil health. PBAT microplastics reduced nutrient availability, disrupted the soil microbial community, and altered root chemistry more than conventional plastic. This finding challenges the assumption that biodegradable plastics are always safer for the environment.

Researchers exposed the fast-growing plant Brassica rapa (related to turnip and cabbage) to polyethylene microplastics that had been degraded by sunlight, finding that the plastics stunted plant growth by up to 51% and triggered cellular stress responses. Genetic analysis revealed the microplastics disrupted the plant's immune and growth pathways, providing insight into how plastic pollution in agricultural soil could affect food crops.
Discrepancy of Growth Toxicity of Polystyrene Nanoplastics on Soybean (Glycine max) and Mung Bean (Vigna radiata)
Researchers compared how polystyrene nanoplastics affect soybean and mung bean plants grown in water and found that both crops suffered root growth suppression, but through different biological pathways. Soybeans showed more oxidative stress at lower doses, while mung beans were more resilient and only showed significant damage at higher concentrations. The study reveals that different crop species can vary widely in their vulnerability to nanoplastic contamination.
Effects of different types of microplastics in soil on nitrogen absorption and metabolism of quinoa
Researchers grew quinoa in soils spiked with biodegradable (PLA, PBAT) and conventional (PE) microplastics at three concentrations, finding that all types reduced nitrogen-metabolizing enzyme activity and soil organic carbon decomposition, with biodegradable PBAT causing the greatest suppression of nitrogen absorption and moderate concentrations inducing the most severe oxidative stress.
LDPE and biodegradable PLA-PBAT plastics differentially affect plant-soil nitrogen partitioning and dynamics in a Hordeum vulgare mesocosm
Researchers compared how conventional LDPE plastic and biodegradable PLA-PBAT plastic affect nitrogen cycling in soil where barley was growing. LDPE microplastics reduced the amount of fertilizer nitrogen taken up by plants and increased nitrogen lost through leaching, while biodegradable plastics boosted microbial activity in the soil. The study shows that different types of plastic pollution affect soil nutrient cycles in different ways, which could influence both crop nutrition and groundwater contamination.
Effects of microplastic type on growth and physiology of soil crops: Implications for farmland yield and food quality
Researchers tested how two common types of microplastics (polypropylene and polyester) affect corn, soybean, and peanut crops grown in real farm conditions. The effects varied by crop and plastic type, with polypropylene generally reducing peanut growth while polyester had milder impacts. These findings suggest that microplastic contamination in agricultural soil could affect crop yields and food quality in ways that depend on which plastics are present.
