Polystyrene Nanoplastics Compromise the Nutritional Value of Radish (Raphanus sativus L.)
AI summary Read the abstract
Researchers found that polystyrene nanoplastics accumulated in radish roots and peels, reducing the vegetable's nutritional quality by disrupting its metabolism at the genetic level. When the contaminated radish was put through a simulated human digestion process, the nanoplastics were released and could potentially be absorbed by the body. This study shows how nanoplastics in soil can reduce the nutritional value of crops and create a direct route of human exposure through everyday vegetables.
The accumulation of nanoplastics (NPs) in crops has drawn global attention due to their potential exacerbation in human health through food chain transfer. The present study investigated the distribution, accumulation, and phytotoxicity of polystyrene (PS) NPs in radish and evaluated the potential risks of PS NPs to human health via a simulated INFOGEST model. PS NPs were mainly accumulated in the cortex and xylem of radish roots and primarily accumulated within the peels via direct adsorption onto tuber surfaces. Transcriptomic and metabolomic analyses revealed that exposure to PS NPs triggered plant defense systems by upregulating gene expression and metabolites involved in flavonoid biosynthesis as well as starch and sucrose metabolisms. However, the downregulation of genes associated with plant hormone signal transduction, as well as the biosynthesis of glucosinolates (the most valued compounds contributing to radish nutrition and flavor), and amino acids reduced crop yield and quality. Importantly, the investigations using a simulated INFOGEST model showed that PS NPs significantly reduced bioaccessibilities or index of nutritional quality (INQ) of amino acids and glucosinolates in the digesta of radish fruits, thereby compromising the nutritional value of radish. These findings further our understanding of the negative effects of NPs-contaminated crops on human digestive tract health.

Determining the accumulation potential of nanoplastics in crops: An investigation of 14C-labelled polystyrene nanoplastic into radishes
AI summary Read the abstract
Researchers used a radioactive labeling technique to track nanoplastics as they moved through radish plants, demonstrating for the first time that these particles can accumulate in edible tissues. About 25% of the nanoplastics absorbed by the roots were found in the edible fleshy root, with another 10% reaching the shoots. The findings highlight a potential pathway for human exposure to nanoplastics through everyday vegetables.
Transport Dynamics and Physiological Responses of Polystyrene Nanoplastics in Pakchoi: Implications for Food Safety and Environmental Health
AI summary Read the abstract
Researchers tracked fluorescently labeled nanoplastics as they traveled through pakchoi (a leafy green vegetable), entering through the roots, moving up through the plant's water-transport system, and accumulating in the leaves. The nanoplastics caused oxidative damage and disrupted plant hormones, demonstrating a clear pathway by which plastic pollution in soil could enter the human food supply through everyday vegetables.
