Field study on the accumulation of trace elements by vegetables produced in the...
Alvarenga, Paula M.; Simões, Isabel; Palma, Patrícia; Amaral, Olga; Matos, João XavierAvailable online 15 November 2013 ; To evaluate the accumulation of trace elements (TE) by vegetables produced in the vicinity of abandoned pyrite mines, eighteen different small farms were selected near three mines from the Portuguese sector of the Iberian Pyrite Belt (São Domingos, Aljustrel and Lousal). Total and bioavailable As, Cu, Pb, and Zn concentrations were analyzed in the soils, and the same TE we...
A contribution towards the risk assessment of soils from the Sao Domingos Mine ...
Alvarenga, Paula; Palma, Patricia; De Varennes, Amarilis; Cunha-Queda, Ana C.This study is a contribution towards a risk assessment of the São Domingos Mine area (Portugal), integrating information from: soil physicochemical characteristics, pseudo-total and bioavailable trace elements (As, Cd, Cr, Cu, Ni, Pb and Zn), ecotoxicological evaluation, and microbial indicators. The bioassays using soil eluates (seed germination, luminescent inhibition of Vibrio fischeri and Daphnia magna immo...
Utilização de Lolium perenne L. na fitoestabilização controlada de solos degrad...
Alvarenga, Paula; Fernandes, Rosa Maria; Varennes, Amarilis; Vallini, Giovanni; Duarte, Elisabeth; Cunha-Queda, Ana CristinaWe studied the application of Lolium per-enne L. and of different organic residues in the assisted phytostabilization of mine-contaminated soils (Aljustrel Mine Area, Iberian Pyrite Belt). Although the applica-tion of the organic residues led to immobilization of Cu, Pb, and Zn in the soil, decreas-ing their effective available fraction, their concentrations in the above-ground plant material did not change. Th...
