Arsenic accumulation and speciation in plants from different habitats

► Submerged plants have a higher accumulation capacity of As than terrestrial and emergent plants. ► The As accumulation factor decreases with increasing soil As concentration. ► Even though submerged soil contains primarily arsenite submerged plants contains more arsenate. ► Even though arid soil contains more arsenate than arsenite terrestrial plants contains more arsenite than arenate.
