| 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. |
