Resumo: | Brazil is one of the countries that most use herbicides in the world. Its indiscriminate use generates adverse effects on the environment and health. 2,4-Dichlorophenoxyacetic acid is among the 3 most used active ingredients in pesticide in Brazil and can be used in several crops. It can be found in surface and deep soils, sediments of rivers, lakes, seas and groundwater. Bioremediation is a technique that can be efficient to reduce the presence of this residue in the soil by treating polluted areas. Many studies have shown the efficiency of anaerobic degradation of 2,4-D through the metabolism of methanogenic, sulfate-reducing or denitrifying microorganisms. Thus, the present study aimed to analyze the degradation of 2,4-D under different oxidation-reduction conditions. Anaerobic degradation tests were carried out under different conditions, methanogenic, denitrifying and sulfetogenic, using the sediment collected in the Itaipú reservoir. The test results show that there was a variation in the removal of 2.4-D between the different oxidation-reduction media, being 9.26% for the denitrifying condition, 63.33% for the sulfetogenic condition and 100% between the methanogenic conditions. Therefore, the methanogenic medium was the one that presented the best conditions for the remediation of the 2,4-D herbicide under the conditions studied. The results presented may contribute to a more complete analysis of the behavior of this compound in the environment, helping to develop more efficient bioremediation processes. |

Su uso indiscriminado genera efectos adversos sobre el medio ambiente y la salud. El ácido 2,4-diclorofenoxiacético se encuentra entre los 3 principios activos plaguicidas más utilizados en Brasil y se utiliza en varios cultivos. Se puede encontrar en suelos superficiales y profundos, sedimentos de ríos, lagos, mares, ríos y aguas subterráneas. La biorremediación es una técnica que puede ser eficiente para reducir la presencia de este residuo en el suelo mediante el tratamiento de áreas contaminadas. Numerosos estudios han demostrado la eficacia de la degradación anaeróbica del 2,4-D a través del metabolismo de microorganismos metanogénicos, sulfatoreductores o desnitrificantes. Por lo tanto, el presente estudio tuvo como objetivo analizar la degradación de 2,4-D en diferentes condiciones de oxidación-reducción. Se realizaron pruebas de degradación anaeróbica en diferentes condiciones, metanogénica, desnitrificante y sulfetogénica, utilizando el sedimento recolectado en el embalse de Itaipú. Los resultados de las pruebas muestran que hubo una variación en la remoción de 2.4-D entre los diferentes medios de oxidación-reducción, siendo 9.26% para la condición desnitrificante, 63.33% para la condición sulfetgénica y 100% entre la condición metanogénica. Por tanto, el medio metanogénico presentó las mejores condiciones para la remediación del herbicida 2,4-D en las condiciones estudiadas. Los resultados presentados pueden contribuir a un análisis más completo del comportamiento de este compuesto en el medio ambiente, ayudando a desarrollar procesos de biorremediación más eficientes.O Brasil é um dos países que mais utiliza herbicidas no mundo. Seu uso indiscriminado gera efeitos adversos ao meio ambiente e a saúde. O ácido 2,4-Diclorofenoxiacético está entre os 3 princípios ativos de pesticida mais utilizados no Brasil e é empregado em diversas lavouras. Pode ser encontrado em solos superficiais e profundos, sedimentos de rios, lagos, mares, águas fluviais e subterrâneas. O processo aeróbio de biodegradação deste herbicida é conhecido e bem relatado na literatura científica, entretanto pouco se sabe sobre o processo anaeróbio de degradação deste composto. Este trabalho se propõe a aprofundar os estudos relacionados a degradação anaeróbia do 2,4-D. Dessa maneira, o presente estudo teve como objetivo a analisar a degradação do 2,4-D em diferentes condições de oxirredução. Para isso, foram realizados ensaios de enriquecimento das comunidades microbianas anaeróbias metanogênicas, sulfatorredutoras e desnitrificantes, na presença de 2,4-D, utilizando como inóculo o sedimento coletado no reservatório de Itaipú. Os resultados dos ensaios apontam que houve variação de remoção do 2,4-D entre os diferentes meios de oxirredução, sendo 9,26%, para a condição desnitrificantes, 63,33%, para a condição sulfetgênica e 100% no meio para a condição metanogênica. Portanto, o meio metanogênico foi o que apresentou melhores condições para a remediação do herbicida 2,4-D nas condições estudadas. Os resultados apresentados podem contribuir para análise mais completa do comportamento deste composto no meio ambiente, ajudando no desenvolvimento de processos de biorremediação mais eficientes.Research, Society and Development2022-04-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2884810.33448/rsd-v11i6.28848Research, Society and Development; Vol. 11 No. 6; e20511628848Research, Society and Development; Vol. 11 Núm. 6; e20511628848Research, Society and Development; v. 11 n. 6; e205116288482525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/28848/25134Copyright (c) 2022 Gabriela Vaz Lobo Barros; Bruna Del Busso Zampieri; Tális Pereira Matias; Gian Paulo Giovanni Freschi; Adriano Barbosa; Leonardo Henrique Soares Damasceno; Gunther Bruchahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBarros, Gabriela Vaz LoboZampieri, Bruna Del Busso Matias, Tális Pereira Freschi, Gian Paulo Giovanni Barbosa, AdrianoDamasceno, Leonardo Henrique Soares Brucha, Gunther2022-05-13T18:04:10Zoai:ojs.pkp.sfu.ca:article/28848Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:46:06.976914Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
