The phytoremediation represents an environmentally friendly alternative to chemical decontamination of sites degraded by various anthropogenic activities. The dendroremediation abilities of some tree species can be combined with the production of the woody biomass for energy purposes. The aim of the paper was to determine the phytoextraction efficiency of total arsenic (As) by two varieties of short rotation coppice willows. The research was conducted in a pot experiment. Dormant cuttings of the varieties were planted into a mining sludge obtained from a tailing pond located in the eastern part of Slovakia. The results of the chemical analysis showed that As was accumulated mainly in the roots of the willow varieties. The highest concentration of As was recorded in the roots of the variety Tora (43.6 mg kg-1). The concentration was almost 50 % higher than the concentration of As in the roots of Gudrun (25.5 mg kg-1). The concentrations of As in the shoots and leaves of Tora were significantly lower compared to the roots (7.2 and 9.1 mg kg-1, respectively). The amounts of As accumulated in the shoots and leaves of Gudrun were lower compared to Tora (4.7 and 6.1 mg kg-1, respectively) pointing to higher phytoextraction performance of Tora.
