ClearNano- 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.
Impacts of Plastics on Plant Development: Recent Advances and Future Research Directions
This review summarizes how microplastics and nanoplastics affect plant growth, from blocking seed germination and root development to causing oxidative stress and DNA damage in plant cells. Nanoplastics are small enough to be absorbed by roots and transported to stems, leaves, and even fruits. These findings are concerning for human health because they show that microplastics can enter the food supply through crops, creating a direct pathway for human exposure through plant-based foods.
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.

Microplastics as emerging stressors in plants: biochemical and metabolic responses
This review examines how microplastics act as environmental stressors in plants, disrupting biochemical and metabolic processes including photosynthesis, antioxidant defenses, and nutrient uptake, with effects varying by polymer type, particle size, and concentration.
Nanoplastic–plant interaction and implications for soil health
This review summarizes research on how nanoplastics interact with plants in soil environments, finding that these tiny particles can be taken up by roots and transported to all plant organs, including edible parts like grain. Researchers found that nanoplastics induce oxidative stress in plants, inhibiting photosynthesis and growth, and can also carry other soil pollutants into plant tissues. The study highlights significant concerns about nanoplastic contamination entering the food chain through agricultural crops.
Occurrence and distribution of micro/nanoplastics in soils and their phytotoxic effects: A review
This review examined how micro- and nanoplastics distribute across different soil types and get taken up by plant roots, finding that smaller, spherical particles are absorbed more easily. Researchers found that these plastic particles accumulate in plants and trigger oxidative stress, which disrupts gene expression and metabolic pathways important for plant growth and biomass production.
Research Progress on the Mechanisms of Terrestrial Plant Uptake, Transport, and Growth Inhibition Responses to Micro (nano) Plastics
This review synthesizes current research on how terrestrial plants take up micro- and nanoplastics from contaminated soil, finding that particles can enter through roots, accumulate in plant tissues, block root function, and trigger oxidative damage that stunts growth. These pathways mean that food crops grown in microplastic-contaminated soils could expose humans to plastic particles through the diet, in addition to the harm caused to agricultural productivity.
Impacts of Micro(nano)plastics on Terrestrial Plants: Germination, Growth, and Litter
This review examines how micro and nanoplastics affect every stage of a plant's life cycle, from seed germination to growth to decomposition of dead plant material. The tiny plastic particles can physically block nutrient and water channels in plants, disrupt photosynthesis, and alter gene expression, with smaller nanoplastics generally causing more harm. These effects on plants are relevant to human health because they could reduce crop yields and allow microplastics to enter the food supply through contaminated produce.
Effects of nanoplastics and compound pollutants containing nanoplastics on plants, microorganisms and rhizosphere systems: A review
This review summarizes how nanoplastics, the tiniest plastic particles, affect plants, soil microorganisms, and the root zone where they interact. Nanoplastics can disrupt photosynthesis, alter gene activity, and reduce microbial diversity, and their harmful effects get worse when they combine with heavy metals or other pollutants. Since plant roots are a key pathway for nanoplastics to enter the food chain, these effects could ultimately impact the safety and nutritional quality of the food we eat.
