Calcium-mediated mitigation of aged nanoplastic-induced stress in microalgae: Insights into photosynthesis, energy metabolism, and antioxidant defense from physiological and multi-omics analyses
Scientists found that tiny plastic particles (nanoplastics) severely damage microalgae, which are important organisms used to clean wastewater before it enters our water supply. However, adding calcium to the water protected the microalgae from this plastic pollution and helped them continue removing harmful substances from wastewater. This research suggests calcium could help maintain clean water treatment systems even as plastic pollution increases in our environment.
Protective role of nano-selenium on Gymnocypris przewalskii under saline–alkaline stress: a comprehensive analysis of transcriptomics and metabolomics
Scientists studied a type of fish that lives in very salty, harsh water and found that tiny selenium particles helped protect the fish from stress and damage. The selenium particles worked by changing how the fish's genes and body chemistry responded to the difficult environment. While this study was done in fish, selenium is an important nutrient for humans too, and this research could help scientists better understand how selenium protects our bodies from environmental stress and damage.
Selenium-driven trophic restructuring of soil nematode communities and biochemical regulation alleviate the toxicity caused by microplastic pollution in highland barley
Researchers investigated whether selenium supplementation could counteract the harmful effects of polyethylene microplastics on highland barley and soil nematode communities. They found that microplastics significantly reduced plant growth metrics and disrupted nematode populations, but selenium application helped restore chlorophyll content, root development, and beneficial soil organism diversity. The study suggests that selenium may serve as a practical tool for mitigating microplastic-induced damage in agricultural soils.

The study found that selenium nanoparticles improved photosynthesis, reduced oxidative damage, and showed strong antifungal activity, suggesting they may help mitigate microplastic-induced phytotoxicity and fungal disease in agricultural settings.
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.
Selenium alleviates the adverse effects of microplastics on kale by regulating photosynthesis, redox homeostasis, secondary metabolism and hormones
Researchers found that treating soil with selenium could protect kale plants from the harmful effects of microplastic contamination. Microplastics triggered damaging oxidative stress in the plants, but selenium helped restore the balance by boosting antioxidant defenses, improving photosynthesis, and regulating plant hormones. This suggests selenium supplementation could help maintain food crop health in microplastic-contaminated agricultural soils.
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.
Unraveling the toxic mechanisms of microplastics in aquatic ecosystem: A case study on Vallisneria natans and Myriophyllum verticillatum
Researchers exposed two submerged aquatic plant species (Vallisneria natans and Myriophyllum verticillatum) to PVC, polystyrene, and polyethylene microplastics at three concentrations, finding that all three types significantly inhibited photosynthesis and growth and triggered oxidative stress, with effects varying by plastic type and plant species.
Natural filters of marine microplastic pollution: implications for plants and submerged environments
Researchers reviewed how vegetated ecosystems — like wetlands and marshes — act as natural filters that trap microplastics before they flow into waterways, but found that these trapped particles can still harm soil health and plant growth by causing oxidative stress. The review highlights a critical gap: plants help protect aquatic environments from microplastic pollution while simultaneously being harmed by it themselves.

Unveiling the Effects of Polypropylene Microplastics (PP-MPs) on Growth Attributes and Antioxidant Defense System in Wheat (Triticum aestivum L.)
Scientists found that tiny plastic particles from everyday items like food containers can harm wheat plants when present in soil at higher levels, stunting their growth and reducing important nutrients. This matters because wheat is a major food crop worldwide, and if microplastics continue building up in farmland soil, it could affect our food supply and the nutritional quality of foods we eat. The study shows that plastic pollution isn't just an ocean problem—it's also threatening the crops that feed us.
