“…Previous reports have indicated that sunflower (Soudek et al, 2004) and rapeseed (Chou et al, 2005) have high 133 Cs uptake capacities and our study supports those results. Borghei et al (2011) grew Calendula alata plants hydroponically in CsCl solutions with concentrations of 0.6, 2, and 5 mg/L, and found that 47%, 41%, and 52%, respectively, of the Cs was remediated after 15 days. Moogouei et al (2011) reported that when Chenopodium album and Amaranthus chlorostachys were exposed to 0.5 mg/L …”

We focused on the Cs uptake capacities of ornamental flowers. Ornamentals have the advantage of beautifying contaminated environments, and this may have therapeutic effects for individuals, especially in disaster areas. Furthermore, the use of ornamental plants will reduce the risk of pollutants entering the food chain. We hypothesized a strong correlation between high aboveground biomass and high Cs uptake in plants. We assessed the potential of 10 ornamental plant species for remediation of 133 Cesium in hydroponic solutions. Sunflower, rapeseed, and cosmos took up larger amounts of 133 Cs and showed better growth rates than the other 7 species. When these 3 species were exposed to 3 different concentrations of 133 Cs (0.5, 2, and 5 mg/L CsCl), more than 48% of the 133 Cs was remediated after 7 days in each case. The highest remediation rate was 67%, by sunflowers grown in 5 mg/L CsCl. Among the 3 species, shoot and root dry weights were highest in sunflower and lowest in cosmos. The rate of 133 Cs uptake was strongly correlated with aboveground plant biomass. The 133 Cs concentration did not affect plant growth rates in any of the three species.

“…Devido ao aumento significativo da contaminação do solo por metais pesados, nas últimas décadas, diversas tecnologias que utilizam espécies de plantas e microrganismos capazes de extrair ou metabolizar elementos nocivos ao meio vêm sendo estudadas para a remediação de áreas impactadas, e são genericamente denominadas de fitorremediação (ANDRADE et al, 2009;MUGOUEI et al, 2011). Nos processos de fitorremediação, os poluentes inorgânicos como os metais pesados não podem ser decompostos, porém são estabilizados no solo ou permanecem retidos nos tecidos de plantas hiperacumuladoras (COBBETT; GOLDSBROUGH, 2002;PEREIRA et al, 2012).…”

Resumo -O mecanismo que envolve a ação de fungos micorrízicos arbusculares (FMAs) na proteção das plantas em solos contaminados tem sido objeto de estudo visando a sua utilização em áreas contaminadas por metais. Nesse sentido, este trabalho teve como objetivo analisar o crescimento micelial de FMAs e seu potencial de formação de micorriza em solos contaminados por cádmio. Para isso, foram instalados dois experimentos em casa de vegetação, em esquema bifatorial, sendo os fatores: a) quatro doses crescentes de Cd (0, 5, 10 e 20 mg kg -1 ) e b) três espécies de FMAs (Rhizophagus clarus, Gigaspora rosea e Acaulospora scrobiculata), e um controle, sendo três repetições por tratamento. Cada unidade experimental foi composta por um sistema construído em PVC, dividido em dois compartimentos por uma malha 40 µm, e mistura de solo e areia como substrato, com uma planta de milho em cada compartimento. A diferença entre os experimentos foi o local de infestação dos FMAs, sendo o experimento 1, infestado em compartimento contaminado por Cd e o experimento 2, infestado em compartimento não contaminado por Cd. Em ambos os experimentos, avaliaram-se: porcentagem e intensidade de colonização, comprimento do micélio extrarradicular total e número de esporos. Todos os FMAs apresentaram comportamento diferenciado na produção de propágulos e formação de micorriza, em função das doses de Cd, nas duas posições de infestação. Verificou-se que houve crescimento micelial de todas as espécies de FMAs em solos contaminados e não contaminados por Cd, mostrando a capacidade desses FMAs crescerem em solos contaminados até 20 mg kg -1 de Cd.Palavras-Chave -contaminação do solo, propágulo, micélio, colonização micorrízica.Abstract -The mechanism that involves the action of arbuscular mycorrhizal fungi (AMF) on the protection of plants in contaminated soils has been object of a study once its use aims in areas contaminated by metals. Thus, in this context, the purpose of this study was to analyze the mycelium growth of AMF and its potential of formation of mycorrhiza in soils contaminated by cadmium. For this, two experiments were performed in greenhouse conduction, using a bi-factorial scheme: a) four increasing doses of Cd (0, 5, 10 e 20 mg kg -1 ) and b) three species of AMF (Rhizophagus clarus, Gigaspora rosea and Acaulospora scrobiculata), and one control, with three replicates per treatment. Each experimental unit consisted of a system constructed in PVC, divided into two compartments by a mesh screen 40 μm, and mixing of soil and sand as a substrate, with one corn plant in each compartment. The difference between two experiments was the place of AMF infestation, with the experiment 1 infected in compartment contaminated by Cd and the experiment 2 infected in compartment non contaminated by Cd. In both experiments, there were analyzed: mycorrhizal colonization and intensity percentage, total extra radicular mycelium length and number of spores. All AMF presented different behavior in the production of propagules and formation of mycorrhiz...

“…However, several studies have concluded that inorganic contaminants can also be dispersed in volatile form in the atmosphere by phytovolatilisation. Phytodegradation/phytotransformation can result in a partial or total reduction of the pollutant content (Moogouei et al, 2011). Contaminants are metabolized in plant tissues.…”
