Summary

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.

Plastic pollution has emerged as a global challenge affecting ecosystem health and biodiversity conservation. Terrestrial environments exhibit significantly higher plastic concentrations compared to aquatic systems. Micro/nano plastics (MNPs) have the potential to disrupt soil biology, alter soil properties, and influence soil-borne pathogens and roundworms. However, limited research has explored the presence and impact of MNPs on aquaculture systems. MNPs have been found to inhibit plant and seedling growth and affect gene expression, leading to cytogenotoxicity through increased oxygen radical production. The article discusses the potential phytotoxicity process caused by large-scale microplastics, particularly those unable to penetrate cell pores. It also examines the available data, albeit limited, to assess the potential risks to human health through plant uptake.
