Avaliação do desenvolvimento de Mentha crispa L. em solo contaminado com cádmio
The objective of this work was to evaluate the behavior of Mentha crispa L. (Garden Mint) in a soil contaminated with different concentrations of Cd. The experimental design was done with five replicates distributed in eight treatments (C0 (control), C1 (1.15 g.kg-1), C2 (1.53 g.kg-1), C3 (2.30 g.kg...

(Garden Mint) in a soil contaminated with different concentrations of Cd. The experimental design was done with five replicates distributed in eight treatments (C0 (control), C1 (1.15 g.kg-1), C2 (1.53 g.kg-1), C3 (2.30 g.kg-1), C4 (4,60 g.kg-1), C5 (9.21 g.kg-1), C6 (18.25 g.kg-1) and C7 (36.87 g.kg-1)). The C5 treatment used the maximum concentration of metal absorbed by the soil, determined through the adsorption isotherm using the Langmuir equation model. The plants were cultivated for 120 days, from June to August 2016, and every 15 days data were collected such as height, number of leaves and number of shoots. Records were made to evaluate the visual symptomatology observing the behavior of the plant in each treatment throughout the experiment period. At the end of the treatment the plants were collected and separated into three parts (leaves, stem and root) and submitted to microwave assisted acid digestion to determine cadmium through Atomic Absorption Spectrometry. It was observed that the height, number of shoots and number of leaves decreased as the concentrations of Cd increased in the treatments. Symptoms of Cd toxicity were observed in plants, such as: chlorosis, leaf blight and wilting. Plants fromC6 and C7 treatments died within 48 hours after contact with contaminated soil. Considering the total amount of cadmium absorbed by the plant, most were retained by the roots and an insignificant part was translocated to the aerial part (stem and leaves). The bioaccumulation factors were calculetd in all treatments and they was greater than one, indicating that the plant is able to accumulate Cd. The plant translocation factor was lower than one in all treatments demonstrating that although a Mentha crispa L. accumulates Cd, it can not be classified as hyperaccumulating, but as phytoextabilizing. Therefore, the Mentha crispa L. can be used to immobilize the metal in contaminated sites. The fact that the metal has pratically not been translocated to the aerial part can be a favorable point in the choice of the plant to be used in the phytoremediation, since the Mentha crispa L., from the economic point of view, may have added value in the extraction of the essential oil, which is produced by the leaves. Capes O objetivo deste trabalho foi avaliar o desenvolvimento de Mentha crispa L. (Hortelã Jardim) em um solo contaminado com diferentes concentrações de Cd. O delineamento experimental foi feito em cinco repetições, distribuído em oito tratamentos (C0(controle), C1(1,15 g.kg-1), C2(1,53 g.kg-1), C3(2,30 g.kg-1), C4(4,60 g.kg-1), C5(9,21 g.kg-1), C6(18,25 g.kg-1) e C7(36,87 g.kg-1)). O tratamento C5 usou a concentração máxima de metal absorvido pelo solo, determinado pela isoterma de adsorção usando o modelo de Langmuir. As plantas foram cultivadas durante 120 dias, no período de junho a agosto de 2016, e a cada 15 dias foram coletados dados como altura, número de folhas e número de brotos. Foram feitos registros para avaliação da sintomatologia visual observando o comportamento da planta em cada tratamento ao longo do período de experimento. Ao final do tratamento as plantas foram coletadas e separadas em três partes (folhas, caule e raiz) e submetidas à digestão ácida assistida por micro-ondas para determinação de cádmio através da Espectrometria de Absorção Atômica. Observou-se que a altura, número de brotos e número de folhas diminuíram conforme aumentavam as concentrações de Cd nos tratamentos. Sintomas da toxicidade do Cd foram observados nas plantas, como: clorose, envergamento da folha e murchamento. As plantas do tratamento C6 e C7 morreram com 48 horas em contato com solo contaminado. Considerando a quantidade total de cádmio absorvida pela planta, a maior parte foi retida pelas raízes e uma parte insignificante foi translocada para a parte aérea (caule e folhas). O fator de bioacumulação calculado em todos os tratamentos foi maior que um, indicando que a planta é capaz de acumular Cd. O fator de translocação da planta foi menor que um em todos os tratamentos, demonstrando que apesar de a Mentha crispa L. acumular Cd, ela não pode ser classificada como hiperacumuladora e sim como Fitoestabilizadora. Portanto, a Mentha crispa L. pode ser usada para imobilizar o metal em locais contaminados. O fato do metal praticamente não ter sido translocado para a parte aérea pode ser um ponto favorável na escolha da planta para ser usada na fitorremediação, já que a Mentha crispa L., do ponto de vista econômico, pode ter valor agregado na extração do óleo essencial que é produzido pelas folhas. 2017-08-11T17:02:53Z 2017-08-11T17:02:53Z 2017-02-23 masterThesis ZEMIANI, Adriana.
