1. Influence of treatment with water-soluble CCB preservative on the physical-mechanical properties of brazilian tropical timber
This aim of this work is to present an analysis of the influence of impregnation against biological demand, realized with saline solution of CCB (Chromated Copper Borate preservative) by vacuum-pressure process, on physical-mechanical properties of tropical wood species Simarouba sp., Cedrelinga catenaeformis and Erisma uncinatum Warm. In theory, such proces

2. Differential Susceptibility of MDF and Commercial Wood to Coptotermes gestroi
ABSTRACT The present study evaluated the foraging and feeding preferences of Coptotermes gestroi (Blattodea: Rhinotermitidae) in wood from four forest species and Medium Density Fiberboard (MDF) in urban areas of the municipalities of Rio de Janeiro, São Gonçalo and Seropédica, RJ, Brazil. Wooden and MDF stakes were buried in the soil in the presence of

3. Tannic extract potential as natural wood preservative of Acacia mearnsii
ABSTRACT High toxicity of the preservatives most frequently used in wood treatment and the resulting risks of handling pose a threat to small producers and to the environment. In an attempt to mitigate these problems, the present study was conducted with the objective of evaluating the preservative effect of tannic extract on biodeterioration of Acacia mearn

5. RESISTÊNCIA BIOLÓGICA DA MADEIRA TRATADA DE Eucalyptus grandis e Eucalyptus cloeziana EM ENSAIOS DE LABORATÓRIO E CAMPO / BIOLOGICAL RESISTANCE OF TREATED WOOD OF Eucalyptus grandis and Eucalyptus cloeziana IN LABORATORY TESTS AND FIELD
A madeira, devido sua origem orgânica, dependendo das condições ambientais que seja exposta, pode ser deteriorada por agentes biológicos. Em vista disto se torna de extrema importância que a mesma, passe por algum tratamento preservativo, com o intuito de aumentar sua vida útil. A presente pesquisa teve por objetivo avaliar a resistência biológica da

7. Eficiência de inseticidas para preservar madeira contra danos de cupim subterrâneo / Efficiency of insecticides to preserve wood against damages of subterranean termite
A field test was developed to evaluate the efficiency of three insecticides as wood preservatives against damages caused by the subterranean termite Coptotermes havilandi Holmgren, 1911 (Isoptera: Rhinotermitidae). The commercial products with their respective appraised active ingredients were: Dursban 4E chlorpyrifos; Diazinon 60 EC diazinon and Dragnet 384

8. Durability of preservative treated Pinus lumber: evaluation through field stake test. / Durabilidade da madeira do gênero Pinus tratada com preservantes: avaliação em campo de apodrecimento.
When used in ground contact, wood is deteriorated by biological agents, as root fungi and subterranean termites. A way to increase the use of wood species of low natural durability, as the Pinus lumber, is the preservative treatment. However, there is a lack of information indicating the durability of treated wood. In order to determine the durability of pre

9. Degradation and O-methylation of chlorinated phenolic compounds by Rhodococcus and Mycobacterium strains.
Three polychlorophenol-degrading Rhodococcus and Mycobacterium strains were isolated independently from soil contaminated with chlorophenol wood preservative and from sludge of a wastewater treatment facility of a kraft pulp bleaching plant. Rhodococcus sp. strain CG-1 and Mycobacterium sp. strain CG-2, isolated from tetrachloroguaiacol enrichment, and Rhodo

10. In Situ Depletion of Pentachlorophenol from Contaminated Soil by Phanerochaete spp
The ability of two white rot fungi to deplete pentachlorophenol (PCP) from soil, which was contaminated with a commercial wood preservative, was examined in a field study. Inoculation of soil containing 250 to 400 μg of PCP g−1 with either Phanerochaete chrysosporium or P. sordida resulted in an overall decrease of 88 to 91% of PCP in the soil in 6.5 week
