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.
Mitigation of microplastic-induced phytotoxicity in poplar micropropagation by multi-walled carbon nanotubes
Researchers exposed in vitro hybrid poplar (Populus alba × P. glandulosa) to polystyrene microplastics and found significant concentration-dependent inhibition of rooting, shoot regeneration, and photosynthesis. Multi-walled carbon nanotubes co-applied with microplastics mitigated toxicity by scavenging reactive oxygen species and supporting cell wall regeneration.
Unlocking the Potential of Carbon Quantum Dots for Cell Imaging, Intracellular Localization, and Gene Expression Control in Arabidopsis thaliana (L.) Heynh.
This paper is not relevant to microplastics research — it investigates how carbon quantum dots are transported and affect gene expression in Arabidopsis plants, with no connection to microplastic contamination.
A Plant Bioreactor for the Synthesis of Carbon Nanotube Bionic Nanocomposites

Researchers investigated how polystyrene microplastics of different sizes and concentrations affect seed germination of three ornamental plant species, finding that nanoscale particles at high concentrations significantly inhibited germination and early growth.
Nanoparticles as catalysts of agricultural revolution: enhancing crop tolerance to abiotic stress: a review
This review looks at how nanoparticles can help crops withstand environmental stresses like drought, salt, and heavy metal contamination. While not directly about microplastics, the research is relevant because nanoparticles and microplastics share similar size ranges and behaviors in soil, and understanding how tiny particles interact with plants helps scientists assess both the risks and potential benefits of nanoscale materials in agriculture.
Effects of nano- & microplastics on terrestrial plants are ubiquitous and widespread: a systematic review
This systematic review finds that nano- and microplastics have widespread negative effects on plants, including reduced germination, stunted growth, and biochemical stress responses. Since plants form the base of our food supply, these findings suggest that microplastic contamination in agricultural soils could affect crop health and potentially the quality of food we eat.
Impact of Titanium Dioxide Nanoparticles on Agricultural Crops Performance: A Review of Efficacy and Mechanisms
This paper is not relevant to microplastics research; it reviews the effects of titanium dioxide nanoparticles on agricultural crop performance, focusing on photosynthesis enhancement and antimicrobial protection rather than plastic pollution.
Recent advances on microplastics/nanoplastics interaction with plant species: A concise review
This review synthesizes research on how microplastics and nanoplastics interact with plants, finding that plastic particles in soil can interfere with root uptake, germination, and crop yields depending on the type and concentration of plastic present. The findings are particularly relevant to human health because food crops grown in microplastic-contaminated agricultural soils may absorb or accumulate plastic particles, creating a direct dietary exposure route.
Micro (nano) plastic pollution: The ecological influence on soil-plant system and human health.
This review examines how micro- and nanoplastics affect soil health, plant growth, and food quality, finding that these particles accumulate in plant root systems and can reduce crop yields and alter nutritional content. Since contaminated soil and water are increasingly delivering microplastics to food crops, these findings are directly relevant to agricultural food safety.
How to improve crop photosynthesis more efficiently using nanomaterials: Lessons from a meta-analysis
Researchers analyzed dozens of studies and found that applying nanomaterials to crops can boost photosynthesis — the process plants use to grow — especially under drought and salt stress conditions, though they caution that lab results may not always translate to real farm fields and that nanoplastics in the soil can reduce these benefits.
Unveiling the mechanism of micro-and-nano plastic phytotoxicity on terrestrial plants: A comprehensive review of omics approaches.
This comprehensive review examined how micro-and-nano plastics (MNPs) in terrestrial soils damage plant health by inhibiting water and nutrient uptake, reducing seed germination, impairing photosynthesis, and inducing oxidative stress. The review identified key knowledge gaps in understanding MNP phytotoxicity mechanisms and their implications for food security.
Effect of Innovative Bio-Based Plastics on Early Growth of Higher Plants
Researchers tested five bio-based plastics on early plant growth and found that monocotyledonous plants were largely unaffected, while PLA-based plastics inhibited root growth in dicotyledonous plants by up to 22% and PBS-based plastic stimulated shoot growth, suggesting bio-based plastic particles are not entirely benign in soil environments.
A Review on Crop Responses to Nanofertilizers for Mitigation of Multiple Environmental Stresses
This review examines how nanoscale fertilizers can help crops survive environmental stresses like drought, salt, and pollution by improving nutrient delivery at the cellular level. While focused on agricultural benefits, the research is relevant to microplastics because nanofertilizers may help plants cope with microplastic-contaminated soil. However, the authors caution that widespread use of nanoparticles in farming raises its own questions about potential effects on the environment and human health.
Can microplastics mediate soil properties, plant growth and carbon/nitrogen turnover in the terrestrial ecosystem?
This review assessed evidence for microplastic effects on soil properties, plant growth, and carbon and nitrogen cycling in terrestrial ecosystems. Microplastics were found to alter soil structure, water retention, microbial activity, and nutrient cycling, with cascading effects on plant growth and soil organic matter turnover.
Microplastic/nanoplastic toxicity in plants: an imminent concern
This review examines the growing body of research on how microplastics and nanoplastics affect terrestrial plants, from root uptake to changes in growth and gene expression. Researchers found that these particles can alter plant physiology and biochemistry at varying degrees depending on particle size and concentration. The study calls for more research on how plastic contamination in soil may ultimately affect food crop quality and human health through the food chain.
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.
