Resumo: The objective of the present work was to evaluate the chemical treatment, durability and leaching of bamboo treated and submitted to rotting field. Stems of Dendrocalamus asper with a diameter between 10 and 15 cm were collected, totaling 12 samples. The chemical treatment consisted of immersion in chromated copper borate (CCB) solutions at concentration of 1 and 3%, and the control treatment (immersion in water). Subsequently, the material was submitted to the rotting field for a period of 5 years. After this period, the material was visually evaluated for deterioration. Representative samples of the treatments and from the soil were collected for spectrometry analyses. The treatment with CCB conferred preservation to the bamboo stems, not showing biological degradation, while the samples from control treatment showed a high stage of decay. When compared with similar studies using wood, the results obtained stand out, where the bamboo treated by immersion in CCB solutions showed high durability. By spectrometry analyses, it was verified that the lower part, in contact with the soil, presented greater leaching of copper and chromium than the aerial part of the stems.

Para isso, foram coletadas hastes de Dendrocalamus asper com diâmetro entre 10 e 15 cm, totalizando 12 amostras. O tratamento químico consistiu de imersão das amostras em solução de borato de cobre cromatado (CCB), nas concentrações de 1 e 3%, e o tratamento controle (imersão em água). Posteriormente, o material foi submetido ao ensaio em campo de apodrecimento por um período de 5 anos. Ao final do período, o material recebeu avaliação visual quanto à deterioração. Foram coletadas amostras representativas dos tratamentos, assim como do solo, para análises de espectrometria. O tratamento com CCB conferiu preservação às hastes de bambu, não apresentando degradação biológica, enquanto o tratamento controle demonstrou estágio elevado de apodrecimento. Quando comparado com estudos semelhantes utilizando madeira, os resultados obtidos se destacaram, sendo que o material de bambu tratado por imersão com CCB apresentou durabilidade elevada. Nas análises de espectrometria, verificou-se que a parte inferior, em contato com o solo, apresentou maior lixiviação de cobre e cromo do que a parte aérea das hastes.Embrapa Florestas2023-06-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/218710.4336/2023.pfb.43e202102187Pesquisa Florestal Brasileira; v. 43 (2023)Pesquisa Florestal Brasileira; Vol. 43 (2023)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2187/1696Copyright (c) 2023 Fernando Rusch, Luana Candaten, Eduarda Bandera, Tauana de Souza Mangini, Laura da Silva Zanchetta, Rômulo Trevisan, Arci Dirceu Wastowskihttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessRusch, FernandoCandaten, LuanaBandera, Eduarda Mangini, Tauana de Souza Zanchetta, Laura da Silva Trevisan, RômuloWastowski, Arci Dirceu 2023-03-16T12:47:49Zoai:pfb.cnpf.embrapa.br/pfb:article/2187Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2023-03-16T12:47:49Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
