Characterization and phytoremediation of abandoned contaminated mining area in ...
Canha, N.; Freitas, M.C.; Anawar, H.M.; Dionísio, I.; Dung, H.M.; Pinto-Gomes, Carlos; Bettencourt, A.This study aims to find out a vascular plant species that accumulate relatively high concentrations of arsenic (As) for its use as phytoremediator ar abandoned and contaminated mining areas, such as São Domingos mines (Portugal). The assessement of As contamination levels in soils and plants of other similar sites in the north of the coutry (Castromil ando Poço de Freitas) was also conducted and the sample anal...

Freitas, M. C.; Pacheco, A. M. G.; Anawar, H. M.; Dionísio, I.; Dung, H. M.; Canha, N.; Bettencourt, A.; Henriques, F.; Pinto-Gomes, CarlosThis study has determined contamination levels in soils and plants from the Sa˜o Domingos mining area, Portugal, by k0-INAA. Total concentrations of As, Sb, Cr, Hg, Cu, Zn and Fe in soils were very high, exceeding the maximum limits in Portuguese legislation. Concentrations of toxic elements like As, Sb and Zn were highest in roots of Erica andevalensis, Juncus acutus, Agrostis castellana and Nicotiana glauca. ...
