Resumo: Trace elements accumulation and translocation in two spontaneous plants of genus Cistus, Cistus ladanifer L. and Cistus monspeliensis L., growing in the Chança mine area, were compared. Samples of plants and soils from rizosphere were collected and characterized. Soil samples showed different total content of arsenic, chromium, copper, manganese, vanadium and zinc, and some of the trace elements had the following total values (mg kg-1): 151 (As); 320 (Cr); 926 (Cu); 1010 (Mn); 235 (V). The concentra-tions of chromium, manganese and vanadium in roots were different between species. In the shoots, only manganese and nickel con-centrations were similar. The two species were manganese accumulators, with C. mon-speliensis exception in one of the sampled areas. Cistus monspeliensis showed the larg-est translocation capacity of trace elements from roots to shoots. Both species presented the translocation coefficient of chromium, manganese, nickel and zinc larger than 1,5.
