Arsenic distribution in soils and plants of an arsenic impacted former mining area

► Environmental assessment of an abandoned arsenical tungsten mining exploitation. ► Under the present soils conditions As mobility is relatively low, with [As]soluble/[As]total ≤ 2%. ► The highest risk of As mobilisation would take place under reducing conditions. ► The shrubs Salix atrocinerea and Genista scorpius are suitable for revegetation. ► The species Scirpus holoschoenus accumulates high As contents at root level.
