The aim of this study was to determine nutrient elements in soybean (Glycine max) plants cultivated in farm soil amended with nCeO2 at 0-1000 mg kg(-1) and nZnO at 0-500 mg kg(-1). Digested samples were analyzed by ICP-OES/MS. Compared to control, pods from nCeO2 at 1000 mg kg(-1) had significantly less Ca but more P and Cu, while pods from 100 mg kg(-1)nZnO had more Zn, Mn, and Cu. Plants treated with nZnO showed significant correlations among Zn, P, and S in pods with Zn in roots. Correlations among pod Zn/root Zn was r = 0.808 (p ≤ 0.01) and pod P/root P was r = 0.541 (p ≤ 0.05). The correlation among pod S/root S was r = -0.65 (p ≤ 0.01). While nCeO2 treatments exhibited significant correlations between pod Ca/root Ca (r = 0.645, p ≤ 0.05). The data suggest that nCeO2 and nZnO alter the nutritional value of soybean, which could affect the health of plants, humans, and animals.
本研究的目的是测定在添加了0 - 1000毫克/千克纳米二氧化铈（nCeO2）和0 - 500毫克/千克纳米氧化锌（nZnO）的农田土壤中种植的大豆（Glycine max）植株中的营养元素。采用电感耦合等离子体发射光谱/质谱仪（ICP - OES/MS）对消化后的样品进行分析。与对照相比，添加1000毫克/千克nCeO2处理的豆荚中钙含量显著降低，但磷和铜含量增加，而添加100毫克/千克nZnO处理的豆荚中锌、锰和铜含量增加。用nZnO处理的植株，豆荚中的锌、磷和硫与根中的锌之间存在显著相关性。豆荚锌/根锌的相关性为r = 0.808（p≤0.01），豆荚磷/根磷的相关性为r = 0.541（p≤0.05）。豆荚硫/根硫的相关性为r = - 0.65（p≤0.01）。而nCeO2处理显示豆荚钙/根钙之间存在显著相关性（r = 0.645，p≤0.05）。数据表明，nCeO2和nZnO会改变大豆的营养价值，这可能会影响植物、人类和动物的健康。
