Bisphenol A (BPA) is a ubiquitous chemical in the environment and potentially harmful to plants. However, relevant studies of the effects of BPA on plants are relatively scarce. In the present work, the effects of BPA on the biomass (fresh wt and dry wt), absorptive function (activity and absorptive area), and mineral element levels in soybean (Glycine max L.) seedling roots treated with 1.5 mg L(-1) , 3.0 mg L(-1) , 6.0 mg L(-1) , 12.0 mg L(-1) , 24.0 mg L(-1) , 48.0 mg L(-1) , and 96.0 mg L(-1) BPA were investigated. Treatment with 1.5 mg L(-1) BPA increased the levels of nitrate and other mineral elements (P, K, Mg, Mn, Zn, and Mo) in the roots, whereas treatments with BPA at higher concentrations decreased the levels of these elements in the roots. All treatments with BPA caused increases in the levels of ammonium, Ca, Fe, and Cu in the roots. Moreover, treatment with 1.5 mg L(-1) BPA increased the fresh weight, dry weight, activity, and absorptive area of the roots, whereas treatments with BPA at higher concentrations decreased these indices in a dose-dependent manner. Furthermore, correlation analysis data showed that BPA affected the levels of mineral elements and absorptive function of soybean seedling roots, which may be the physiological basis of BPA action on plants.
双酚A（BPA）是环境中一种普遍存在的化学物质，对植物可能有害。然而，关于BPA对植物影响的相关研究相对较少。在本研究中，研究了用1.5毫克/升、3.0毫克/升、6.0毫克/升、12.0毫克/升、24.0毫克/升、48.0毫克/升和96.0毫克/升BPA处理的大豆（Glycine max L.）幼苗根系的生物量（鲜重和干重）、吸收功能（活性和吸收面积）以及矿质元素水平。用1.5毫克/升BPA处理可提高根系中硝酸盐和其他矿质元素（磷、钾、镁、锰、锌和钼）的水平，而较高浓度BPA处理则会降低根系中这些元素的水平。所有BPA处理均导致根系中铵、钙、铁和铜的水平升高。此外，用1.5毫克/升BPA处理可增加根系的鲜重、干重、活性和吸收面积，而较高浓度BPA处理则以剂量依赖的方式降低这些指标。此外，相关性分析数据表明，BPA影响大豆幼苗根系的矿质元素水平和吸收功能，这可能是BPA对植物作用的生理基础。
