With the increasing industrialization, heavy metals concentration in soils has greatly increased. Phytoremediation is a low-cost, non-intrusive and aesthetically harmonious technology that uses plants to remediate contaminated sites by heavy metals. The aim of the study was to determine Cd, Pb and Zn concentration in the biomass of plant species growing on a multi-metal-contaminated site of lead smelter processing, to assess the workability of using these plants for phytoremediation purposes and highlight possible damage in morphological leaf changes. Two plant species, i.e., Ipomoea asarifolia and Urochloa decumbens and the associated soil samples were collected and analyzed Cd, Pb and Zn concentrations and then calculating the bioconcentration factor and translocation factor parameters for each element. Leaves and roots samples were observed by light microscopy. Metal concentrations varied greatly and majorly depend on site sampled, plant species and tissue. Cd, Pb and Zn in tissue ranged from 0 to 102.48, 0 to 381.04 and 12.84 to 295.02 mg Kg?1. However, none of the plant showed potential for hyperaccumulation. Both plants showed bioaccumulation factor more than one, where it was 7.66 and 6.82 for Pb and Zn in U. decumbens, respectively. Translocation factor was calculated below one for both plants and all metals. Morphological studies revealed development of adaptive features that strengthen the U. decumbens to grow in contaminated soil. Our study suggests that I. asarifolia and U. decumbens have potential for phytostabilization at multi-metal-contaminated site.

Os produtos de sensoriamento remoto constituem ferramentas importantes para mapeamentos e monitoramentos do uso e da cobertura das terras. O mapeamento do uso e da cobertura das terras em área rural do Município de Guararapes (SP) nos anos de 1972 e 2009 foi realizado por meio de interpretação visual de fotografias aéreas (1972) e de imagens do sensor AVNIR do satélite ALOS (2009). As alterações verificadas entre esses dois anos foram caracterizadas e quantificadas, como subsídio para estudos da dinâmica agropecuária regional e de seus impactos ambientais e socioeconômicos, importantes para ações de planejamento e gestão territorial na região. As pastagens, que cobriam 77% da área de estudo em 1972, foram reduzidas para 45% em 2009, como consequência sobretudo da grande expansão da cultura da cana-de-açúcar. |
