Phytoextraction technologies uses plants to extract toxics metals from contaminated soils and accumulate them in the harvestable parts of the plants, which can then be removed from site. This work describe inconclusive results of the phytoextracion capacity of three kind of plants: 1) hyperaccumulator plant species such as Brassica napus, 2) fast-growing non-hyperaccumulator plants such as Festuca arundinacea (Both 1 and 2 grown in Pb industrial level contaminated soil), and 3) Lolium perenne grown in Pb contaminated soil and in crops of hydroponics.
SR µXRF technique offers a powerful approach for probing and mapping the distribution of Pb in selected sections of plant tissues. The measurements were carried out at the D09B XRF Fluorescence beamline of the LNLS. Preparation of contaminated soil, seed selection, seeding, control of handling plant growth variables, selective harvesting and preparation of samples for SR µXRF were done at CEPROCOR.
