Accumulation and Toxicity of Nanoplastics in Photosynthetic‐Species
Summary
This review examines how nanoplastics, plastic particles smaller than one micrometer, affect plants ranging from algae to crop species. Researchers found that nanoplastics can cross plant cell barriers and interfere with photosynthesis, growth, and gene expression. The study highlights that the small size of nanoplastics makes them particularly concerning because they can penetrate deeper into plant tissues than larger microplastics.
Abstract This plastic waste degrades into nanoparticles, which are referred to as nanoplastics (NPs) pollutants, due to faulty reuse and recycling processes. These micro and nano plastic pollutants have the ability to absorb and interact with common pollutants and have a high surface area to volume ratio, which causes serious effects on the environment, especially plants. The size of pollutants is so small that they can cross the biological barriers and affect the cellular and molecular levels. Exposure to nanoplastics in photosynthetic species affects the growth and photosynthesis mechanism of the plants. Nanoplastics also affect humans through intake of the exposed plant materials. These pollutants can be plastic pellets, personal care products, marine coatings, synthetic textiles, etc. Plastic pollutants may enter the human body mainly through contaminated food and water. This review incorporates the toxicity of such pollutant and how their remediation is being done. The focus is also on the advancement of detection and remediation techniques.

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.
Impacts of Micro/Nanoplastics on Crop Physiology and Soil Ecosystems: A Review
This review synthesized evidence on how micro- and nanoplastics affect crop physiology and soil ecosystems, covering how plastic particles enter plants via roots, disrupt soil microbiota, and impair crop growth through oxidative stress, nutrient cycling disruption, and physical root interference. The authors found that nanoplastics pose greater plant risks than microplastics due to their ability to cross cell membranes.
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.
Micro- and nanoplastics-induced stress in plants: uptake, physiological disruption, and toxicity mechanisms
This review paper summarizes existing research on how tiny plastic particles (called microplastics and nanoplastics) are absorbed by plants and damage their health. These plastic particles can build up in plant tissues and disrupt how plants grow and function, which matters because we eat these plants. Since plastic pollution keeps breaking down into smaller pieces that plants absorb, this could eventually affect the safety and quality of our food supply.
The threat of micro/nanoplastic to aquatic plants: current knowledge, gaps, and future perspectives
This review summarizes what is known about how micro- and nanoplastics affect aquatic plants, including how plants absorb these particles through roots and leaves and transport them internally. Exposure can alter plant growth, photosynthesis, and interactions with other organisms, though effects vary widely depending on plastic type and concentration. The authors highlight major research gaps and call for more studies on real-world conditions rather than controlled lab settings.
