ClearThe Effect of Microplastics-Plants on the Bioavailability of Copper and Zinc in the Soil of a Sewage Irrigation Area
Researchers examined how different concentrations of microplastics affect the bioavailability of copper and zinc in sewage-irrigated soils, finding that microplastics can alter heavy metal mobility and plant uptake, with implications for food safety in contaminated agricultural areas.
Zinc oxide nanoparticles and polyethylene microplastics affect the growth, physiological and biochemical attributes, and Zn accumulation of rice seedlings
Researchers found that both zinc oxide nanoparticles and polyethylene microplastics disrupted growth, physiology, and zinc uptake in two rice cultivars, with nanoparticles having a stronger effect than microplastics, and responses varying by cultivar and dose.
The synergy of microplastics with the heavy metal zinc has resulted in reducing the toxic effects of zinc on lentil (Lens culinaris) seed germination and seedling growth
Researchers investigated how polyethylene microplastics interact with zinc heavy metal contamination in lentil seed germination experiments. Unexpectedly, they found that the presence of microplastics actually reduced zinc toxicity to the plants, likely because the microplastics bound to zinc ions in solution and limited plant uptake. The study suggests that microplastic-metal interactions in agricultural soils may be more complex than simple additive toxicity.
Zinc ions enhance tolerance to nanoplastics stress in rice seedlings: Advancing the development and optimization of traditional zinc fertilizers
Researchers tested whether traditional zinc sulfate fertilizer could help rice seedlings tolerate polystyrene microplastic stress, as an alternative to zinc oxide nanoparticles which carry their own environmental risks. They found that appropriate zinc levels reduced oxidative damage through different mechanisms in shoots versus roots, restoring photosynthesis and development. The findings offer a practical, lower-risk strategy for protecting crops from microplastic contamination in agricultural soils.
Microplastics modify plant-arbuscular mycorrhizal fungi systems in a Pb-Zn-contaminated soil
Researchers examined how six types of microplastics affect sweet sorghum growth and soil fungal communities in soil contaminated with lead and zinc. They found that microplastics generally did not inhibit plant growth and in some cases promoted it, but they increased the uptake of heavy metals into plant shoots. The study suggests that microplastics may worsen the risks of heavy metal contamination in agricultural soils by enhancing metal accumulation in crops.
Molecular Effects of Biogenic Zinc Nanoparticles on the Growth and Development of Brassica napus L. Revealed by Proteomics and Transcriptomics
This study investigated how biogenic zinc nanoparticles affect the growth and development of rapeseed plants using proteomics and transcriptomics approaches. While not directly focused on microplastics, the research contributes to understanding how nano-scale particles interact with plant biology at the molecular level.
Assessing the combined impacts of microplastics and nickel oxide nanomaterials on soybean growth and nitrogen fixation potential
This study tested how polystyrene microplastics and nickel oxide nanoparticles affect soybean growth and nitrogen fixation in soil. Microplastics alone reduced photosynthesis, plant hormones, and the beneficial root bacteria that help plants capture nitrogen from the air. While this is a plant and soil study, it demonstrates how microplastics can disrupt agricultural ecosystems that humans depend on for food production.
The effects of biosolid microplastics on rhizosphere respiration of root exudates in Glycine max
This study examined how microplastics from agricultural biosolids affect the activity of soil microbes around soybean roots. Researchers found that both polyethylene and polypropylene microplastics increased baseline microbial respiration rates, and high concentrations of polypropylene fragments significantly altered how soil microbes consumed amino acid-based root compounds. The findings suggest that microplastics in agricultural soil can change the way root-zone microbial communities process plant nutrients.
Single and composite damage mechanisms of soil polyethylene/polyvinyl chloride microplastics to the photosynthetic performance of soybean (Glycine max [L.] merr.)
This study found that both polyethylene and PVC microplastic stress caused oxidative damage in soybean plants, impairing the structure and function of photosystem II and ultimately reducing net photosynthesis rates, with implications for crop productivity in microplastic-contaminated agricultural soils.
Transcriptomic mechanism for foliar applied nano-ZnO alleviating phytotoxicity of nanoplastics in corn (Zea mays L.) plants
Researchers found that applying zinc oxide nanoparticles to corn leaves helped protect the plants from the harmful effects of nanoplastic pollution. The nano-zinc treatment reduced nanoplastic accumulation in leaves and reversed much of the damage to plant growth and photosynthesis caused by the plastic particles. The study suggests that nano-fertilizers could serve as a tool for managing nanoplastic stress in agricultural crops.

Not relevant to microplastics — this study tests the effects of zinc oxide nanostructures applied as foliar sprays on cucumber seedling growth, comparing different synthesis methods and a commercial zinc sulfate fertilizer.
Employing Phytoremediation Methods to Extract Heavy Metals from Polluted Soils
This paper is not directly about microplastics in the typical environmental exposure sense; it studies phytoremediation — using the Dodonaea plant to absorb heavy metals (zinc, nickel, cadmium) from contaminated soil — with no connection to plastic or microplastic pollution.
Dopamine Hydrochloride Alleviates the Salt-induced Stress in Glycine max (L.) Merr. plant
This paper is not about microplastics. It studied how dopamine hydrochloride can alleviate salt stress in soybean plants by improving antioxidant defenses and molecular responses. The study has no connection to microplastic contamination or human health effects from plastic pollution.
Microplastics affect the nitrogen nutrition status of soybean by altering the nitrogen cycle in the rhizosphere soil
Researchers investigated how three types of microplastics — polystyrene, polyethylene, and polyvinyl chloride — affect soybean growth by altering nitrogen cycling in the root-zone soil. They found that polyethylene and polystyrene promoted nitrogen availability and soybean growth, while polyvinyl chloride disrupted the nitrogen cycle, reduced beneficial soil microorganisms, and inhibited plant growth. The study suggests that different types of microplastics can have opposing effects on crop nutrition through their impact on soil microbial communities.
Microplastics in Mediterranean Agricultural Soils: Effects on Soil Properties, Metal Accumulation in Plants, and Implications for Sustainable Agroecosystems
Scientists found that tiny plastic particles in soil make it easier for toxic metals like lead and zinc to move into plants we might eat. Even small amounts of microplastics changed how metals behave in the soil, with some types of plastic causing up to 20% more metal absorption in plants. This matters because these contaminated plants could end up in our food supply, potentially increasing our exposure to harmful metals.
Effects of polyethylene microplastics and cadmium co-contamination on the soybean-soil system: Integrated metabolic and rhizosphere microbial mechanisms
Researchers investigated how polyethylene microplastics and cadmium interact in soybean-soil systems and found that specific microplastic concentrations enhanced cadmium accumulation in roots under moderate contamination. Higher microplastic levels reduced beneficial soil bacteria like Sphingomonas and Bradyrhizobium and suppressed nitrogen-cycling functions. The study demonstrates that microplastics fundamentally alter heavy metal behavior through interconnected plant-metabolite-microbe interactions in agricultural soils.
Integrating Chlorophyll a Fluorescence and Enzymatic Profiling to Reveal the Wheat Responses to Nano-ZnO Stress
Not relevant to microplastics — this study examines how different wheat cultivars respond to zinc oxide nanoparticle stress in soil, using chlorophyll fluorescence and enzyme activity to identify tolerant varieties.
[Effect of Low-density Polyethylene Microplastics on Soybean-soil-microbial System].
A pot experiment explored how different concentrations of low-density polyethylene microplastics affect soybean plants, the soil they grow in, and the microbial communities in that soil. Higher microplastic concentrations inhibited soybean growth, reduced soil enzyme activity, and altered microbial diversity in ways that could impair soil fertility. As microplastic contamination of agricultural soils continues to grow, these findings suggest real risks to food crop productivity and soil ecosystem health.
Effects of polystyrene microplastics on uptake and toxicity of phenanthrene in soybean
This study examined how polystyrene microplastics of different sizes affect soybean plants' uptake of the pollutant phenanthrene. Researchers found that microplastics reduced soybean roots' ability to absorb phenanthrene, but micron-sized particles caused more oxidative damage to roots than nano-sized ones, which paradoxically reduced pollutant uptake further. The study highlights that combined exposure to microplastics and organic pollutants can harm crop plants, with the specific effects depending on plastic particle size.
Effects of Co-Contamination of Microplastics and Cd on Plant Growth and Cd Accumulation
Researchers investigated how two types of microplastics, high-density polyethylene and polystyrene, at various concentrations affect cadmium uptake and toxicity in maize plants grown in agricultural soil. The study found that while polyethylene alone had no significant effect, polystyrene at higher doses altered cadmium accumulation patterns, suggesting that different plastic types may interact differently with heavy metals in soil.
Response of soybean (Glycine max L.) seedlings to polystyrene nanoplastics: Physiological, biochemical, and molecular perspectives
Researchers examined the effects of polystyrene nanoplastics on soybean seedlings in a hydroponic experiment and confirmed that the nanoparticles were taken up by plant roots. The study found that nanoplastic exposure negatively affected growth, increased mineral content in roots and leaves, caused oxidative stress, and altered gene expression related to stress response and hormone signaling pathways.
Microplastics change soil properties, heavy metal availability and bacterial community in a Pb-Zn-contaminated soil
This study found that adding six different types of microplastics to soil contaminated with lead and zinc changed the soil's chemistry, increased the availability of those toxic metals, and shifted the bacterial communities living in the soil. Higher doses of microplastics caused greater disruption, reducing microbial diversity and altering nutrient cycling. The findings suggest that microplastics in contaminated soil could make heavy metals more likely to enter plants and the food chain.
Revealing the Combined Effects of Microplastics, Zn, and Cd on Soil Properties and Metal Accumulation by Leafy Vegetables: A Preliminary Investigation by a Laboratory Experiment
