摘要:The absorption, distribution, and transport trends of organic and inorganic arsenic (As) in honesuckle (Lonicera japonica) were studied using synchrotron X-ray fluorescence spectroscopy (mu-XRF). The root, stem, and leaf samples were analyzed by mu-XRF, proving that in the presence of dimethyl arsenate acid, a small amount of As accumulated in local areas of the epidermis and cortex of roots, while most of As migrated to the upper plant through the middle vascular column. After reaching the stem, As was mainly distributed in the outer skin, indicating that the root and stem of L. japonica blocked the transport of As in the plant. In the presence of As(iii), A large amount of As accumulated in the epidermis and cortex of the root, reducing its further transport from the plant roots. Once As entered the stem of L. japonica from the root, it achieved a strong transport capacity, thus causing severe harm to plants. The element correlation analysis revealed that As in L. japonica had the strongest correlation with Cu and Zn elements, for the future research on the influence of As pollution on plants, the interference based on the above two elements can be considered.
