A B S T R A C TLead is a toxic metal that affects plant growth and the ecosystem. This study evaluated the lead (Pb) bioaccumulation potential of vetiver (Vetiveria zizanioides L.), sunflower (Helianthus annuus L.), elephant ear (Alocasia macrorrhiza) and 'embaúba' (Cecropia sp.). The plant species were tested in a 50% nutrient solution -Hoagland and Arnon, constantly aerated, containing five Pb concentrations: 0, 50, 100, 200 and 400 mg L ). Pb concentration of up to 100 and 50.9 mg L -1 stimulated sunflower biomass and root length, respectively. None of the evaluated species met the hyperaccumulator criterion; however, sunflower and vetiver have the potential to be tested for phytostabilization purposes.Mudanças induzidas no crescimento de quatro espécies vegetais pela toxicidade de chumbo A biomassa e o comprimento radicular de girassol foram estimulados até a concentração de 100 e 50,9 mg L -1 de Pb, respectivamente. Nenhuma das espécies atendeu aos critérios de hiperacumulação; entretanto, girassol e vetiver devem ser testados como espécies fitoestabilizadoras.

“…Huang and Cunningham (1996) observed that Pb reduced Mg concentrations in shoots of Z. mays and A. artemisiifolia plants. Lamhamdi et al (2013) reported that Pb concentrations higher than 1.5 mM significantly decreased Mg contents in shoots and roots of Triticum aestivum and Spinacia oleracea seedlings.…”

“…Increased proline biosynthesis has been considered to play an important role in plant tolerance to Pb stress (POURRUT et al, 2011;QURESHI et al, 2007;DUBEY, 2005). Lamhamdi et al (2013) found that proline contents increased in leaves of T. aestivum and S. oleracea when the plants were exposed to increasing Pb concentrations. According to Verbruggen and Hermans (2008), proline contents may vary among species, and their values are up to 100 times higher in stressed plants than those in control ones.…”

However, little research has been conducted on the damage caused by Pb to physiological and biochemical processes in sunflower (Helianthus annuus L.).…”

The aim of this study was to evaluate the effects of increasing concentrations of lead (Pb) in the nutrient solution on growth and macronutrient and organic solute contents of Helianthus annuus plants. The experimental design was completely randomized with four replications. The dry mass yield was not affected by the treatments up to a Pb concentration of 0.6 mM, indicating that H. annuus was tolerant to this Pb concentration in the growth medium. The reductions in leaf, stem and root dry masses at a Pb concentration of 0.8 mM were 74, 84 and 85%, respectively. Lead stress did not reduce the levels of nitrogen (N), phosphorus (P) and potassium (K), indicating that the growth reduction observed at 0.8 mM Pb could not be attributed to deficiencies of these nutrients. On the other hand, Pb significantly reduced calcium (Ca) and magnesium (Mg) contents in leaves, stems and roots, which might, at least in part, explain the Pb-induced growth reduction in the H. annuus plants. Pb increased soluble carbohydrate, free amino acid and proline contents in leaves, and soluble protein and proline contents in roots, showing stress-induced changes in cell metabolism. The data also suggest that Ca and Mg concentrations may be used as nutritional indicators and the proline content may be used as a biochemical indicator of Pb toxicity in H. annuus.

“…Thus, the imbalance of nutrients and decreasing of plant biomass might be a convenient and reliable symptom of heavy metal toxicity in plants. On the other hand, lead accumulation in plant tissues increases with an increase in the exogenous lead level (Lamhamdi et al 2013). Therefore, plant species with high accumulation ability in their organs are good candidates for heavy metal remediation.…”

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.
