Nano Size Plastic Particles – Accumulation in Mature Peanut and Rice Reported

The abstract of an October 17, 2022, Advanced Science study by researchers with China Zhejiang University report: “… Nanoplastics are emerging pollutants of global concern. Agricultural soil is becoming a primary sink for nanoplastics generated from plastic debris … whether nanoplastics can enter grains and their impact on the grains of crop grown in contaminated soil is still unknown. Here, the translocation of polystyrene nanoplastics (PS-NPs) in crops, including peanut … and rice … is investigated. It is demonstrated PS-NPs translocation from the root and accumulation in the grains at the maturation stage … PS-NPs exerted adverse effects on nutritional quality, such as decreasing the content of mineral elements, amino acids, and unsaturated fatty acids … this is the first report of the presence of nanoplastics in the grains of crop plants grown in soil containing nanoplastics, and the results highlight the impact of nanoplastics on the yield and nutritional quality of crop grains …” #NanoPlastics #MicroPlastics #PlasticWaste #SingleUsePlastic
