Atriplex atacamensis and Atriplex halimus resist As contamination in Pre-Andean soils (northern Chile)

► A. atacamensis and A. halimus resist high levels of arsenic in soils. ► A. halimus accumulated higher levels of arsenic than A. atacamensis. ► A atacamensis retains arsenic in the roots and A. halimus translocated it to leaves. ► Both species can be recommended to generate plant cover in As-contaminated soils.
