Researchers found that polyethylene microplastics cause transcriptomic and physiological changes in corn seedlings, altering gene expression related to stress responses and growth, while also serving as vectors that increase the bioavailability of organic pollutants to plant roots.
Nano- and microplastics commonly cause adverse impacts on plants at environmentally relevant levels: A systematic review
Systematic review of 78 studies found that nano- and microplastics commonly cause adverse effects on plants even at environmentally relevant concentrations, with germination and root growth more strongly affected than shoot growth during early development. Chlorophyll levels were consistently reduced while stress indicators (ROS) and antioxidant enzymes were consistently upregulated across species.
Physiological Toxicity and Antioxidant Mechanism of Photoaging Microplastics on Pisum sativum L. Seedlings
Researchers tested the toxicity of pristine and photoaged microplastics made of four different polymers (PS, PA, PE, PET) on pea seedlings. The study found that photoaged microplastics caused more harm to root growth than pristine ones, generated reactive oxygen species that worsened oxidative stress, and disrupted nutrient transport in plant tissues. These findings suggest that environmental weathering of microplastics increases their toxicity to plants through enhanced oxidative damage.
Effect of polypropylene microplastics on seed germination and nutrient uptake of tomato and cherry tomato plants
Researchers tested the effects of polypropylene microplastics on tomato and cherry tomato seed growth in lab conditions. While microplastics did not significantly affect germination, they did alter how plants absorbed certain nutrients like potassium and calcium. This suggests that microplastic-contaminated soil could subtly change the nutritional quality of food crops, even if the plants appear to grow normally.
Micro (nano) plastics uptake, toxicity and detoxification in plants: Challenges and prospects
This review examines how micro and nanoplastics are taken up by plants, covering their toxic effects on growth and gene expression as well as potential detoxification strategies. Smaller nanoplastics can penetrate plant cell walls and accumulate in tissues, causing oxidative stress and genetic damage. The findings are important for human health because contaminated crops could transfer microplastics directly into the food supply.
Micro and nanoplastics pollution: Sources, distribution, uptake in plants, toxicological effects, and innovative remediation strategies for environmental sustainability
This review examines how microplastics and nanoplastics enter plants through roots, disrupt growth and photosynthesis, and cause oxidative stress that reduces crop yields. Because these plastic particles can move through plant tissues and into edible parts, they represent a potential pathway for microplastics to enter the human food supply.
Adsorption, uptake and toxicity of micro- and nanoplastics: Effects on terrestrial plants and aquatic macrophytes
This review summarizes research on how micro- and nanoplastics interact with terrestrial plants and aquatic macrophytes, finding that many species can absorb or take up plastic particles. Both short-term and long-term plastic exposure triggered stress responses in plants, and since plants are at the base of food chains and a major part of the human diet, there is concern about plastics moving up through the food web. The findings suggest that plastic pollution could potentially affect plant productivity and broader ecosystem function.

Foliar uptake and leaf-to-root translocation of nanoplastics with different coating charge in maize plants
Researchers showed that nanoplastics can enter maize plants not just through roots but also through leaves, and then travel down to the roots through the plant's internal transport system. Positively charged nanoplastics stuck to leaf surfaces more readily but also caused more damage to photosynthesis and triggered stronger stress responses in the plants. This finding is important because it reveals an additional pathway for nanoplastic contamination of food crops through airborne particles landing on leaves.
