Study on arsenic speciation and redistribution mechanism in <i>Lonicera japonica</i> plants via synchrotron techniques

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