双酚 A (BPA) 是环境中普遍存在的化学物质，对植物可能有害。然而，有关BPA对植物影响的相关研究却相对较少。在本工作中，BPA 对经 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 和研究了 96.0 mg L−1 BPA。用 1.5 mg L−1 BPA 处理增加了根中硝酸盐和其他矿物元素（P、K、Mg、Mn、Zn 和 Mo）的水平，而用较高浓度的 BPA 处理则降低了根中这些元素的水平。所有使用 BPA 的处理都会导致根部的铵、钙、铁和铜含量增加。此外，用 1.5 mg L−1 BPA 处理增加了根部的鲜重、干重、活性和吸收面积，而用较高浓度的 BPA 处理则以剂量依赖性方式降低了这些指数。此外，相关分析数据表明，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。环境毒理学化学 2015；34：133–140。 © 2014 塞塔克
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.
