“…Growth disorders and biomass reductions are commonly observed in plants subjected to high levels of metal contamination (Panich-Pat et al 2010). The decline in plant growth occurs due to the adverse effect of heavy metals on cell division and may be due to their influence on DNA, RNA or protein metabolism (Auda & Ali 2010).…”

Phytoremediation is an effective and affordable approach to extract or remove lead from contaminated soil. An understanding of the physiological responses of different species subjected to heavy metal contamination is necessary before considering their use for environmental clean-up. The objective of this study was to assess the effect of lead (Pb) on growth and nutrient uptake in three forest species native to Iran: Cappadocian maple (Acer cappadocicum), European ash (Fraxinus excelsior) and Oriental aborvitae (Platycladus orientalis). The capability of lead uptake in different organs was studied in oneyear-old potted seedlings grown in contaminated soils with Pb concentration ranging from 100 to 500 mg kg -1 for six months in a nursery. Several phytoextraction parameters such as translocation factor (TF), tolerance index (TI) and bioconcentration factor (BCF) were assessed to investigate the phytoremediation potential of these species. Increasing Pb application in the soil caused a gradual decrease in dry weight of leaf and shoot of all species, while the dry weight of root remains unaffected. However, such inhibition was less marked in the conifer (P. orientalis) compared to the two broad-leaf species. Phosphorus uptake of all species slightly declined in contaminated soils. Contrastingly, Pb application did not hinder nitrogen and potassium uptake in seedlings. Atomic absorption thermo electron analysis of Pb-treated plants showed an increasing Pb accumulation in all plant compartments, although the result was more evident in the tissues of P. orientalis. This species also showed the highest values for TF, TI and BCF, indicating this conifer species as a potential candidate for phytoremediation of lead-polluted soils in Iran.

“…The both M(II) ions are well-known as toxic metals to living things in nature [17], but were employed here as simply model metal ones. Additionally, Bz was selected because a lot of data for the extraction of these M(II) ions with B18C6 or 18-crown-6 ether (18C6) is available [1, 3,6,8,[18][19][20].…”

“…La fitoremediación se define como el uso de plantas para eliminar, destruir o transformar contaminantes del suelo, agua y aire (Zhi-xin et al, 2007;Panich-Pat et al, 2010). En este proceso, las plantas son seleccionadas principalmente por su potencial fisiológico, como en el caso de enzimas presentes para tolerar y asimilar sustancias tóxicas, por sus tasas de crecimiento, por la profundidad de sus raíces y su habilidad para bioacumular y/o degradar contaminantes Ospina-Álvarez et al, 2006;Wei et al, 2009).…”

Madera-Parra, J.M. Sánchez, J. Medina-Vásquez: Bioprospección de plantas nativas para su uso en procesos de biorremediación: caso Helicona psittacorum (heliconiaceae). Rev. Acad. Colomb. Cienc. 37 (145): 469-481, 2013. ISSN 0370-3908. La fitoremediación es el proceso que emplea la vegetación para el tratamiento de la contaminación en el agua, suelo y aire. Los Humedales artificiales de flujo sub-superficial y superficial, constituyen la principal aplicación tecnológica para la matriz agua, basada en un tipo de plantas cuya características principales son la hiperacumulación de sustancias toxicas, y transformación de dichos compuestos gracias a sus propiedades biológicas. Recientemente, se han estudiado el empleo de especies nativas como el caso de las Heliconias, cuyo uso más reconocido es en la ornamentación. Los estudios realizados con Heliconia psitttacorum para evaluar su potencial fitorremediador se ha logrado demostrar que la especie presenta características adecuadas a las condiciones en los humedales construidos para el tratamiento de aguas residuales, a partir de su capacidad de eliminación de DBO 5 , DQO y SST, por encima del 70 % de remoción sin detrimento de sus propiedades fisiológicas. Los resultados aquí presentados plantean la necesidad de ampliar la evaluación del desempeño de especies nativas frente a la capacidad de tolerancia de las mismas para el manejo del estrés del contaminante. Esta información complementaria es importante para identificar los problemas del tratamiento de aguas residuales mediante la fitoremediación en zonas tropicales.Palabras clave: fitoremediación, humedales artificiales, Heliconia, plantas hiperacumuladoras.
