Arsenic speciation in submerged and terrestrial soil-plant systems

Abstract

In a series of cultivation experiments in unsaturated and water-saturated soil/sediment, As speciation was determined in the terrestrial plant lettuce and the emergent plant common cottongrass. Arsenic species were analyzed in soils and plants using XANES/EXAFS and HPLC-AAS. The transformation process between As species was much faster in plant tissue than in soil. When arsenite was present in soil, plant roots contained more arsenate than arsenite. Lettuce growing in terrestrial soil with no arsenite contained more arsenate in shoots than arsenite, in contrast to common cottongrass. Differences in the arsenate/arsenite-ratio of plant tissue indicated both plant species and environmental differences. © 2014 Taylor & Francis Group.
