Özet
Bu çalışmada mavi renk oluşumunun emprenye edilmiş ağaç malzemeden Cu, Cr ve As elementlerinin yıkanması üzerine etkisi incelenmiştir. Dört fark-lı mavi renk mantarı ile mavileşmiş örnekler %1 konsantrasyonda CCA-C çözeltisi ile emprenye edildikten sonra 14 gün süren yıkama işlemlerine tabi tutulmuştur. Araştırma sonucunda mavi renk oluşumun yıkanan element yüzdeleri üzerine önemli bir etkisi olmadığı belirlenmiştir.
Abstract
In this study, the effect of blue-staining on the teachability of CCA ele-ments from CCA-C treated and stained red pine specimens was evaluated. The specimens were first blue-stained in laboratory conditions using Cera-tocystis pilifera, C. huntii, C. coerulescens, and Anrobasidium putlulans fungi and then treated with 1% CCA-C solution. After fixation period, the speci-mens were subjected to 336-h of leaching according to modified AWPA stan-dard method. The blue-staining fungi used in this study had no effect on ma-jor wood components, however subsequent degradation of ray parenchyma, tracheid walls and pits by blue-staining fungi used in this study caused incre-asing of permeability of wood. On the basis of all leached elements, C. pilife-/o« and C. huntii caused somewhat more leaching of CCA from the specimens compared to percentage leaching rate of CCA in control specimens.
