In the present work, we focused on soils contaminated with elevated lead concentrations in an agricultural and residential area surrounding a lead smelter plant in Bouwer, province of Córdoba, Argentina. The aim of this research work was to assess the phytoextraction suitability of native plant species growing in the vicinity of a former lead smelter.The lead concentration in leaves, stems and roots was determined in ten species collected at ten sampling sites along a lead concentration gradient in soil. It was found that at circa 1,600 μg g -1 Pb HCl 0,5 M extractable concentration in soil two native species, Tagetes minuta L.

“…Recently, the removal of metal ions by low-cost and eco-friendly biosorption processes utilizing lichen biomass has been explored (Ekmekyapar et al, 2006;Uluözlü et al, 2008Uluözlü et al, , 2010Bingöl et al, 2009;Tüzen et al, 2009). Lichen thallus is particularly favored because lichens do not have root systems, nor do they have waxy cuticles, and thus they are strongly dependent on wet and dry deposition for their mineral nutrients (Bermudez et al, 2009), especially epiphytic species. They have a high surfacevolume ratio and ion exchange properties; unlike many other plants, they lack variability in morphology throughout the growing season and they have no cuticle.…”

The biosorption characteristics of Cu(II) ions from aqueous solution using Lobaria pulmonaria (L.) Hoffm. biomass were investigated. The biosorption efficiency of Cu(II) onto biomass was significantly influenced by the operating parameters. The maximum biosorption efficiency of L. pulmonaria was 65.3% at 10 mg/L initial metal concentration for 5 g/L lichen biomass dosage. The biosorption of Cu(II) ions onto biomass fits the Langmuir isotherm model and the pseudo-second-order kinetic model well. The thermodynamic parameters indicate the feasibility and exothermic and spontaneous nature of the biosorption. The effective desorption achieved with HCl was 96%. Information on the nature of possible interactions between the functional groups of the L. pulmonaria biomass and Cu(II) ions was obtained via Fourier transform infrared (FTIR) spectroscopy. The results indicated that the carboxyl (-COOH) and hydroxyl (-OH) groups of the biomass were mainly involved in the biosorption of Cu(II) onto L. pulmonaria biomass. The L. pulmonaria is a promising biosorbent for Cu(II) ions because of its availability, low cost, and high metal biosorption and desorption capacities.Implications: Lobaria pulmonaria is a promising biosorbent for Cu(II) ions because of its availability, low cost, and high metal biosorption and desorption capacities. To the best of our knowledge, this is the first paper on the biosorption Cu by L. pulmonaria.

“…Regarding this subject, we must highlight the species of Tillandsia, known as biomonitors of air quality, due to their high tolerance to pollution in urban areas (Graciano et al 2003, Alves et al 2008, Bermudez et al 2009). Thus, changes resulting from anthropogenic disturbances, such as increases in luminosity and temperature, reduction of humidity, scarcity of pollinators and pollution, can act as environmental filters, turning the occurrence of species that cannot tolerate such changes and opening space for the establishment and proliferation of other species in such environments, including accidental holoepiphytes, due to reduced competition.…”

“…In addition, we investigated the floristic similarity of this community with other areas composed of urban seasonal forests in the same phytogeographic domain. Based on data available in the literature, we tested the following hypotheses: 1) the study area has low richness and diversity of epiphytic species, suggesting that urban areas tend to be more susceptible to human impacts (McKinney 2006(McKinney , 2008; 2) the specific and generic composition and the proportion of ecological categories tend to be similar between urban areas as some species are more tolerant to anthropogenic stresses (Barthlott et al 2001, Bermudez et al 2009); 3) Because humidity is an important factor for the establishment of epiphytes (Johansson 1974, Benzing 1990, the areas closer to the ocean are clustered by separating those that are farther away from the ocean.…”

-(Diversity, vertical structure and floristic relationships of vascular epiphytes in an urban remnant of the Brazilian Atlantic Forest). This study was conducted in a fragment of montane seasonal semi-deciduous forest (Minas Gerais State) with a history of anthropogenic disturbance. Our goals were to characterise the composition, structure and floristic diversity of vascular epiphytes and to investigate the floristic similarities of the community with other areas of urban seasonal forests in Brazil. We sampled 61 phorophytes with 47 epiphytic species. The richest families were Bromeliaceae (seven) and Polypodiaceae (seven). The most common ecological category was accidental holoepiphytes with 21 speciesan unprecedented result for the Neotropical region. The Shannon index was 2.95 and the Pielou evenness index 0.77, showing a relatively high diversity with a few dominant species and numerous rare species. Similarity analyses showed a longitudinal gradient and strong influence of the distance from the ocean on floristic relationships as well as influence of dense ombrophilous forests on the composition of the vascular epiphytes of the surveyed area. Keywords: accidental holoepiphytes, biodiversity hotspot, multivariate analyses, taxonomic diversity, urban forest RESUMO -(Diversidade, estrutura vertical e relações florísticas de epífitas vasculares em um remanescente urbano da Floresta Atlântica brasileira). Este estudo foi realizado em um fragmento de floresta estacional semidecidual montana (Minas Gerais) com histórico de perturbação antrópica. Os objetivos foram caracterizar a composição, estrutura e diversidade florística das epífitas vasculares e investigar a similaridade florística da comunidade com outras áreas de florestas estacionais urbanas no Brasil. Foram amostrados 61 forófitos e registradas 47 espécies de epífitas. As famílias mais ricas foram Bromeliaceae (sete) e Polypodiaceae (sete). A categoria ecológica mais comum foi a de holoepífitas acidentais com 21 espécies -um resultado inédito na Região Neotropical. O índice de Shannon foi 2,95 e o índice de uniformidade de Pielou foi 0,77, mostrando diversidade relativamente alta com certa dominância de poucas espécies, enquanto as espécies raras foram numerosas. Análises de similaridade mostraram gradiente longitudinal e forte influência da distância do oceano sobre as relações florísticas, assim como influência das florestas ombrófilas densas sobre a composição das epífitas vasculares na área estudada. Palavras-chave: análises multivariadas, diversidade taxonômica, floresta urbana, holoepífitas acidentais, "hotspot" de biodiversidade
